what is an introduction in a literature review

How to write a literature review introduction (+ examples)

The introduction to a literature review serves as your reader’s guide through your academic work and thought process. Explore the significance of literature review introductions in review papers, academic papers, essays, theses, and dissertations. We delve into the purpose and necessity of these introductions, explore the essential components of literature review introductions, and provide step-by-step guidance on how to craft your own, along with examples.

Why you need an introduction for a literature review

When you need an introduction for a literature review, what to include in a literature review introduction, examples of literature review introductions, steps to write your own literature review introduction.

A literature review is a comprehensive examination of the international academic literature concerning a particular topic. It involves summarizing published works, theories, and concepts while also highlighting gaps and offering critical reflections.

In academic writing , the introduction for a literature review is an indispensable component. Effective academic writing requires proper paragraph structuring to guide your reader through your argumentation. This includes providing an introduction to your literature review.

It is imperative to remember that you should never start sharing your findings abruptly. Even if there isn’t a dedicated introduction section .

Instead, you should always offer some form of introduction to orient the reader and clarify what they can expect.

There are three main scenarios in which you need an introduction for a literature review:

• Academic literature review papers: When your literature review constitutes the entirety of an academic review paper, a more substantial introduction is necessary. This introduction should resemble the standard introduction found in regular academic papers.
• Literature review section in an academic paper or essay: While this section tends to be brief, it’s important to precede the detailed literature review with a few introductory sentences. This helps orient the reader before delving into the literature itself.
• Literature review chapter or section in your thesis/dissertation: Every thesis and dissertation includes a literature review component, which also requires a concise introduction to set the stage for the subsequent review.

It is crucial to customize the content and depth of your literature review introduction according to the specific format of your academic work.

In practical terms, this implies, for instance, that the introduction in an academic literature review paper, especially one derived from a systematic literature review , is quite comprehensive. Particularly compared to the rather brief one or two introductory sentences that are often found at the beginning of a literature review section in a standard academic paper. The introduction to the literature review chapter in a thesis or dissertation again adheres to different standards.

Here’s a structured breakdown based on length and the necessary information:

Academic literature review paper

The introduction of an academic literature review paper, which does not rely on empirical data, often necessitates a more extensive introduction than the brief literature review introductions typically found in empirical papers. It should encompass:

• The research problem: Clearly articulate the problem or question that your literature review aims to address.
• The research gap: Highlight the existing gaps, limitations, or unresolved aspects within the current body of literature related to the research problem.
• The research relevance: Explain why the chosen research problem and its subsequent investigation through a literature review are significant and relevant in your academic field.
• The literature review method: If applicable, describe the methodology employed in your literature review, especially if it is a systematic review or follows a specific research framework.
• The main findings or insights of the literature review: Summarize the key discoveries, insights, or trends that have emerged from your comprehensive review of the literature.
• The main argument of the literature review: Conclude the introduction by outlining the primary argument or statement that your literature review will substantiate, linking it to the research problem and relevance you’ve established.
• Preview of the literature review’s structure: Offer a glimpse into the organization of the literature review paper, acting as a guide for the reader. This overview outlines the subsequent sections of the paper and provides an understanding of what to anticipate.

By addressing these elements, your introduction will provide a clear and structured overview of what readers can expect in your literature review paper.

Regular literature review section in an academic article or essay

Most academic articles or essays incorporate regular literature review sections, often placed after the introduction. These sections serve to establish a scholarly basis for the research or discussion within the paper.

In a standard 8000-word journal article, the literature review section typically spans between 750 and 1250 words. The first few sentences or the first paragraph within this section often serve as an introduction. It should encompass:

• An introduction to the topic: When delving into the academic literature on a specific topic, it’s important to provide a smooth transition that aids the reader in comprehending why certain aspects will be discussed within your literature review.
• The core argument: While literature review sections primarily synthesize the work of other scholars, they should consistently connect to your central argument. This central argument serves as the crux of your message or the key takeaway you want your readers to retain. By positioning it at the outset of the literature review section and systematically substantiating it with evidence, you not only enhance reader comprehension but also elevate overall readability. This primary argument can typically be distilled into 1-2 succinct sentences.

In some cases, you might include:

• Methodology: Details about the methodology used, but only if your literature review employed a specialized method. If your approach involved a broader overview without a systematic methodology, you can omit this section, thereby conserving word count.

By addressing these elements, your introduction will effectively integrate your literature review into the broader context of your academic paper or essay. This will, in turn, assist your reader in seamlessly following your overarching line of argumentation.

Introduction to a literature review chapter in thesis or dissertation

The literature review typically constitutes a distinct chapter within a thesis or dissertation. Often, it is Chapter 2 of a thesis or dissertation.

Some students choose to incorporate a brief introductory section at the beginning of each chapter, including the literature review chapter. Alternatively, others opt to seamlessly integrate the introduction into the initial sentences of the literature review itself. Both approaches are acceptable, provided that you incorporate the following elements:

• Purpose of the literature review and its relevance to the thesis/dissertation research: Explain the broader objectives of the literature review within the context of your research and how it contributes to your thesis or dissertation. Essentially, you’re telling the reader why this literature review is important and how it fits into the larger scope of your academic work.
• Primary argument: Succinctly communicate what you aim to prove, explain, or explore through the review of existing literature. This statement helps guide the reader’s understanding of the review’s purpose and what to expect from it.
• Preview of the literature review’s content: Provide a brief overview of the topics or themes that your literature review will cover. It’s like a roadmap for the reader, outlining the main areas of focus within the review. This preview can help the reader anticipate the structure and organization of your literature review.
• Methodology: If your literature review involved a specific research method, such as a systematic review or meta-analysis, you should briefly describe that methodology. However, this is not always necessary, especially if your literature review is more of a narrative synthesis without a distinct research method.

By addressing these elements, your introduction will empower your literature review to play a pivotal role in your thesis or dissertation research. It will accomplish this by integrating your research into the broader academic literature and providing a solid theoretical foundation for your work.

Comprehending the art of crafting your own literature review introduction becomes significantly more accessible when you have concrete examples to examine. Here, you will find several examples that meet, or in most cases, adhere to the criteria described earlier.

Example 1: An effective introduction for an academic literature review paper

To begin, let’s delve into the introduction of an academic literature review paper. We will examine the paper “How does culture influence innovation? A systematic literature review”, which was published in 2018 in the journal Management Decision.

The entire introduction spans 611 words and is divided into five paragraphs. In this introduction, the authors accomplish the following:

• In the first paragraph, the authors introduce the broader topic of the literature review, which focuses on innovation and its significance in the context of economic competition. They underscore the importance of this topic, highlighting its relevance for both researchers and policymakers.
• In the second paragraph, the authors narrow down their focus to emphasize the specific role of culture in relation to innovation.
• In the third paragraph, the authors identify research gaps, noting that existing studies are often fragmented and disconnected. They then emphasize the value of conducting a systematic literature review to enhance our understanding of the topic.
• In the fourth paragraph, the authors introduce their specific objectives and explain how their insights can benefit other researchers and business practitioners.
• In the fifth and final paragraph, the authors provide an overview of the paper’s organization and structure.

In summary, this introduction stands as a solid example. While the authors deviate from previewing their key findings (which is a common practice at least in the social sciences), they do effectively cover all the other previously mentioned points.

Example 2: An effective introduction to a literature review section in an academic paper

The second example represents a typical academic paper, encompassing not only a literature review section but also empirical data, a case study, and other elements. We will closely examine the introduction to the literature review section in the paper “The environmentalism of the subalterns: a case study of environmental activism in Eastern Kurdistan/Rojhelat”, which was published in 2021 in the journal Local Environment.

The paper begins with a general introduction and then proceeds to the literature review, designated by the authors as their conceptual framework. Of particular interest is the first paragraph of this conceptual framework, comprising 142 words across five sentences:

“ A peripheral and marginalised nationality within a multinational though-Persian dominated Iranian society, the Kurdish people of Iranian Kurdistan (a region referred by the Kurds as Rojhelat/Eastern Kurdi-stan) have since the early twentieth century been subject to multifaceted and systematic discriminatory and exclusionary state policy in Iran. This condition has left a population of 12–15 million Kurds in Iran suffering from structural inequalities, disenfranchisement and deprivation. Mismanagement of Kurdistan’s natural resources and the degradation of its natural environmental are among examples of this disenfranchisement. As asserted by Julian Agyeman (2005), structural inequalities that sustain the domination of political and economic elites often simultaneously result in environmental degradation, injustice and discrimination against subaltern communities. This study argues that the environmental struggle in Eastern Kurdistan can be asserted as a (sub)element of the Kurdish liberation movement in Iran. Conceptually this research is inspired by and has been conducted through the lens of ‘subalternity’ ” ( Hassaniyan, 2021, p. 931 ).

In this first paragraph, the author is doing the following:

• The author contextualises the research
• The author links the research focus to the international literature on structural inequalities
• The author clearly presents the argument of the research
• The author clarifies how the research is inspired by and uses the concept of ‘subalternity’.

Thus, the author successfully introduces the literature review, from which point onward it dives into the main concept (‘subalternity’) of the research, and reviews the literature on socio-economic justice and environmental degradation.

While introductions to a literature review section aren’t always required to offer the same level of study context detail as demonstrated here, this introduction serves as a commendable model for orienting the reader within the literature review. It effectively underscores the literature review’s significance within the context of the study being conducted.

Examples 3-5: Effective introductions to literature review chapters

The introduction to a literature review chapter can vary in length, depending largely on the overall length of the literature review chapter itself. For example, a master’s thesis typically features a more concise literature review, thus necessitating a shorter introduction. In contrast, a Ph.D. thesis, with its more extensive literature review, often includes a more detailed introduction.

Numerous universities offer online repositories where you can access theses and dissertations from previous years, serving as valuable sources of reference. Many of these repositories, however, may require you to log in through your university account. Nevertheless, a few open-access repositories are accessible to anyone, such as the one by the University of Manchester . It’s important to note though that copyright restrictions apply to these resources, just as they would with published papers.

Master’s thesis literature review introduction

The first example is “Benchmarking Asymmetrical Heating Models of Spider Pulsar Companions” by P. Sun, a master’s thesis completed at the University of Manchester on January 9, 2024. The author, P. Sun, introduces the literature review chapter very briefly but effectively:

PhD thesis literature review chapter introduction

The second example is Deep Learning on Semi-Structured Data and its Applications to Video-Game AI, Woof, W. (Author). 31 Dec 2020, a PhD thesis completed at the University of Manchester . In Chapter 2, the author offers a comprehensive introduction to the topic in four paragraphs, with the final paragraph serving as an overview of the chapter’s structure:

PhD thesis literature review introduction

The last example is the doctoral thesis Metacognitive strategies and beliefs: Child correlates and early experiences Chan, K. Y. M. (Author). 31 Dec 2020 . The author clearly conducted a systematic literature review, commencing the review section with a discussion of the methodology and approach employed in locating and analyzing the selected records.

Having absorbed all of this information, let’s recap the essential steps and offer a succinct guide on how to proceed with creating your literature review introduction:

• Contextualize your review : Begin by clearly identifying the academic context in which your literature review resides and determining the necessary information to include.
• Outline your structure : Develop a structured outline for your literature review, highlighting the essential information you plan to incorporate in your introduction.
• Literature review process : Conduct a rigorous literature review, reviewing and analyzing relevant sources.
• Summarize and abstract : After completing the review, synthesize the findings and abstract key insights, trends, and knowledge gaps from the literature.
• Craft the introduction : Write your literature review introduction with meticulous attention to the seamless integration of your review into the larger context of your work. Ensure that your introduction effectively elucidates your rationale for the chosen review topics and the underlying reasons guiding your selection.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : Predictors and Outcomes of U.S. Quality Maternity Leave: A Review and Conceptual Framework:  10.1177/08948453211037398  

Systematic review : "The authors of a systematic review use a specific procedure to search the research literature, select the studies to include in their review, and critically evaluate the studies they find." (p. 139). Nelson, L. K. (2013). Research in Communication Sciences and Disorders . Plural Publishing.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

Meta-analysis : "Meta-analysis is a method of reviewing research findings in a quantitative fashion by transforming the data from individual studies into what is called an effect size and then pooling and analyzing this information. The basic goal in meta-analysis is to explain why different outcomes have occurred in different studies." (p. 197). Roberts, M. C., & Ilardi, S. S. (2003). Handbook of Research Methods in Clinical Psychology . Blackwell Publishing.

• Example : Employment Instability and Fertility in Europe: A Meta-Analysis:  10.1215/00703370-9164737

Meta-synthesis : "Qualitative meta-synthesis is a type of qualitative study that uses as data the findings from other qualitative studies linked by the same or related topic." (p.312). Zimmer, L. (2006). Qualitative meta-synthesis: A question of dialoguing with texts .  Journal of Advanced Nursing , 53 (3), 311-318.

• Example : Women’s perspectives on career successes and barriers: A qualitative meta-synthesis:  10.1177/05390184221113735

What is a Literature Review? | Guide, Template, & Examples

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research.

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarise sources – it analyses, synthesises, and critically evaluates to give a clear picture of the state of knowledge on the subject.

• Quick Run-through
• Step 1 & 2

When you write a dissertation or thesis, you will have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. We’ve written a step-by-step guide that you can follow below.

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

You can use our free APA Reference Generator for quick, correct, consistent citations.

To begin organising your literature review’s argument and structure, you need to understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly-visual platforms like Instagram and Snapchat – this is a gap that you could address in your own research.

There are various approaches to organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarising sources in order.

Try to analyse patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organise your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text, your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, discussing the significance of findings in relation to the literature as a whole.
• Critically evaluate: mention the strengths and weaknesses of your sources.
• Write in well-structured paragraphs: use transitions and topic sentences to draw connections, comparisons and contrasts.

In the conclusion, you should summarise the key findings you have taken from the literature and emphasise their significance.

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a dissertation , thesis, research paper , or proposal .

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarise yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

The literature review process involves a number of steps.

This guide focuses on:

• evaluating.

A literature review is a survey and critical analysis of what has been written on a particular topic, theory, question or method.

"In writing the literature review, the purpose is to explore what knowledge and ideas have been established on a topic, what approaches and viewpoints have been adopted, and what are their strengths and weaknesses."

The type of literature review you do will depend on a variety of factors:

• Your discipline
• The purpose - undergraduate assessment, PHD thesis, journal article?
• Your lecturer or supervisor's requirements

Always follow the guidelines outlined by your lecturer or supervisor or consult the instructions for authors (for journal articles), when conducting your literature review.

• is an overview of the significant literature on a topic
• typically includes a critical analysis of each work included
• demonstrates the reviewers knowledge of the topic
• is a list of citations of research sources (books, journal articles, websites etc) on a topic
• includes a brief summary and analysis or evaluation of each citation = the annotation
• a critical assessment of all research studies on a particular research question
• has specific criteria for collecting and evaluating the literature
• includes a synthesis of the findings of the included studies
• This method developed by Griffith University's School of Environment bridges the gap between traditional narrative review methods and meta-analyses to enable students to produce results that are reliable, quantifiable and reproducible.

The requirements of narrative literature reviews are usually quite different than systematic reviews . However, you may be required to adopt some of the characteristics of a systematic approach when doing your literature review. Check the guidelines or criteria that have been set by your supervisor so you know what is expected of you.

What is a Literature Review? How to Write It (with Examples)

A literature review is a critical analysis and synthesis of existing research on a particular topic. It provides an overview of the current state of knowledge, identifies gaps, and highlights key findings in the literature. 1 The purpose of a literature review is to situate your own research within the context of existing scholarship, demonstrating your understanding of the topic and showing how your work contributes to the ongoing conversation in the field. Learning how to write a literature review is a critical tool for successful research. Your ability to summarize and synthesize prior research pertaining to a certain topic demonstrates your grasp on the topic of study, and assists in the learning process.

What is a literature review?

A well-conducted literature review demonstrates the researcher’s familiarity with the existing literature, establishes the context for their own research, and contributes to scholarly conversations on the topic. One of the purposes of a literature review is also to help researchers avoid duplicating previous work and ensure that their research is informed by and builds upon the existing body of knowledge.

What is the purpose of literature review?

A literature review serves several important purposes within academic and research contexts. Here are some key objectives and functions of a literature review: 2  

• Contextualizing the Research Problem: The literature review provides a background and context for the research problem under investigation. It helps to situate the study within the existing body of knowledge. 
• Identifying Gaps in Knowledge: By identifying gaps, contradictions, or areas requiring further research, the researcher can shape the research question and justify the significance of the study. This is crucial for ensuring that the new research contributes something novel to the field. 
• Understanding Theoretical and Conceptual Frameworks: Literature reviews help researchers gain an understanding of the theoretical and conceptual frameworks used in previous studies. This aids in the development of a theoretical framework for the current research. 
• Providing Methodological Insights: Another purpose of literature reviews is that it allows researchers to learn about the methodologies employed in previous studies. This can help in choosing appropriate research methods for the current study and avoiding pitfalls that others may have encountered. 
• Establishing Credibility: A well-conducted literature review demonstrates the researcher’s familiarity with existing scholarship, establishing their credibility and expertise in the field. It also helps in building a solid foundation for the new research. 
• Informing Hypotheses or Research Questions: The literature review guides the formulation of hypotheses or research questions by highlighting relevant findings and areas of uncertainty in existing literature. 

Literature review example

Let’s delve deeper with a literature review example: Let’s say your literature review is about the impact of climate change on biodiversity. You might format your literature review into sections such as the effects of climate change on habitat loss and species extinction, phenological changes, and marine biodiversity. Each section would then summarize and analyze relevant studies in those areas, highlighting key findings and identifying gaps in the research. The review would conclude by emphasizing the need for further research on specific aspects of the relationship between climate change and biodiversity. The following literature review template provides a glimpse into the recommended literature review structure and content, demonstrating how research findings are organized around specific themes within a broader topic. 

Literature Review on Climate Change Impacts on Biodiversity:

Climate change is a global phenomenon with far-reaching consequences, including significant impacts on biodiversity. This literature review synthesizes key findings from various studies: 

a. Habitat Loss and Species Extinction:

Climate change-induced alterations in temperature and precipitation patterns contribute to habitat loss, affecting numerous species (Thomas et al., 2004). The review discusses how these changes increase the risk of extinction, particularly for species with specific habitat requirements. 

b. Range Shifts and Phenological Changes:

Observations of range shifts and changes in the timing of biological events (phenology) are documented in response to changing climatic conditions (Parmesan & Yohe, 2003). These shifts affect ecosystems and may lead to mismatches between species and their resources. 

c. Ocean Acidification and Coral Reefs:

The review explores the impact of climate change on marine biodiversity, emphasizing ocean acidification’s threat to coral reefs (Hoegh-Guldberg et al., 2007). Changes in pH levels negatively affect coral calcification, disrupting the delicate balance of marine ecosystems. 

d. Adaptive Strategies and Conservation Efforts:

Recognizing the urgency of the situation, the literature review discusses various adaptive strategies adopted by species and conservation efforts aimed at mitigating the impacts of climate change on biodiversity (Hannah et al., 2007). It emphasizes the importance of interdisciplinary approaches for effective conservation planning. 

How to write a good literature review

Writing a literature review involves summarizing and synthesizing existing research on a particular topic. A good literature review format should include the following elements. 

Introduction: The introduction sets the stage for your literature review, providing context and introducing the main focus of your review. 

• Opening Statement: Begin with a general statement about the broader topic and its significance in the field. 
• Scope and Purpose: Clearly define the scope of your literature review. Explain the specific research question or objective you aim to address. 
• Organizational Framework: Briefly outline the structure of your literature review, indicating how you will categorize and discuss the existing research. 
• Significance of the Study: Highlight why your literature review is important and how it contributes to the understanding of the chosen topic. 
• Thesis Statement: Conclude the introduction with a concise thesis statement that outlines the main argument or perspective you will develop in the body of the literature review. 

Body: The body of the literature review is where you provide a comprehensive analysis of existing literature, grouping studies based on themes, methodologies, or other relevant criteria. 

• Organize by Theme or Concept: Group studies that share common themes, concepts, or methodologies. Discuss each theme or concept in detail, summarizing key findings and identifying gaps or areas of disagreement. 
• Critical Analysis: Evaluate the strengths and weaknesses of each study. Discuss the methodologies used, the quality of evidence, and the overall contribution of each work to the understanding of the topic. 
• Synthesis of Findings: Synthesize the information from different studies to highlight trends, patterns, or areas of consensus in the literature. 
• Identification of Gaps: Discuss any gaps or limitations in the existing research and explain how your review contributes to filling these gaps. 
• Transition between Sections: Provide smooth transitions between different themes or concepts to maintain the flow of your literature review. 

Conclusion: The conclusion of your literature review should summarize the main findings, highlight the contributions of the review, and suggest avenues for future research. 

• Summary of Key Findings: Recap the main findings from the literature and restate how they contribute to your research question or objective. 
• Contributions to the Field: Discuss the overall contribution of your literature review to the existing knowledge in the field. 
• Implications and Applications: Explore the practical implications of the findings and suggest how they might impact future research or practice. 
• Recommendations for Future Research: Identify areas that require further investigation and propose potential directions for future research in the field. 
• Final Thoughts: Conclude with a final reflection on the importance of your literature review and its relevance to the broader academic community. 

Conducting a literature review

Conducting a literature review is an essential step in research that involves reviewing and analyzing existing literature on a specific topic. It’s important to know how to do a literature review effectively, so here are the steps to follow: 1  

Choose a Topic and Define the Research Question:

• Select a topic that is relevant to your field of study. 
• Clearly define your research question or objective. Determine what specific aspect of the topic do you want to explore? 

Decide on the Scope of Your Review:

• Determine the timeframe for your literature review. Are you focusing on recent developments, or do you want a historical overview? 
• Consider the geographical scope. Is your review global, or are you focusing on a specific region? 
• Define the inclusion and exclusion criteria. What types of sources will you include? Are there specific types of studies or publications you will exclude? 

Select Databases for Searches:

• Identify relevant databases for your field. Examples include PubMed, IEEE Xplore, Scopus, Web of Science, and Google Scholar. 
• Consider searching in library catalogs, institutional repositories, and specialized databases related to your topic. 

Conduct Searches and Keep Track:

• Develop a systematic search strategy using keywords, Boolean operators (AND, OR, NOT), and other search techniques. 
• Record and document your search strategy for transparency and replicability. 
• Keep track of the articles, including publication details, abstracts, and links. Use citation management tools like EndNote, Zotero, or Mendeley to organize your references. 

Review the Literature:

• Evaluate the relevance and quality of each source. Consider the methodology, sample size, and results of studies. 
• Organize the literature by themes or key concepts. Identify patterns, trends, and gaps in the existing research. 
• Summarize key findings and arguments from each source. Compare and contrast different perspectives. 
• Identify areas where there is a consensus in the literature and where there are conflicting opinions. 
• Provide critical analysis and synthesis of the literature. What are the strengths and weaknesses of existing research? 

Organize and Write Your Literature Review:

• Literature review outline should be based on themes, chronological order, or methodological approaches. 
• Write a clear and coherent narrative that synthesizes the information gathered. 
• Use proper citations for each source and ensure consistency in your citation style (APA, MLA, Chicago, etc.). 
• Conclude your literature review by summarizing key findings, identifying gaps, and suggesting areas for future research. 

The literature review sample and detailed advice on writing and conducting a review will help you produce a well-structured report. But remember that a literature review is an ongoing process, and it may be necessary to revisit and update it as your research progresses. 

Frequently asked questions

A literature review is a critical and comprehensive analysis of existing literature (published and unpublished works) on a specific topic or research question and provides a synthesis of the current state of knowledge in a particular field. A well-conducted literature review is crucial for researchers to build upon existing knowledge, avoid duplication of efforts, and contribute to the advancement of their field. It also helps researchers situate their work within a broader context and facilitates the development of a sound theoretical and conceptual framework for their studies.

Literature review is a crucial component of research writing, providing a solid background for a research paper’s investigation. The aim is to keep professionals up to date by providing an understanding of ongoing developments within a specific field, including research methods, and experimental techniques used in that field, and present that knowledge in the form of a written report. Also, the depth and breadth of the literature review emphasizes the credibility of the scholar in his or her field.  

Before writing a literature review, it’s essential to undertake several preparatory steps to ensure that your review is well-researched, organized, and focused. This includes choosing a topic of general interest to you and doing exploratory research on that topic, writing an annotated bibliography, and noting major points, especially those that relate to the position you have taken on the topic. 

Literature reviews and academic research papers are essential components of scholarly work but serve different purposes within the academic realm. 3 A literature review aims to provide a foundation for understanding the current state of research on a particular topic, identify gaps or controversies, and lay the groundwork for future research. Therefore, it draws heavily from existing academic sources, including books, journal articles, and other scholarly publications. In contrast, an academic research paper aims to present new knowledge, contribute to the academic discourse, and advance the understanding of a specific research question. Therefore, it involves a mix of existing literature (in the introduction and literature review sections) and original data or findings obtained through research methods. 

Literature reviews are essential components of academic and research papers, and various strategies can be employed to conduct them effectively. If you want to know how to write a literature review for a research paper, here are four common approaches that are often used by researchers.  Chronological Review: This strategy involves organizing the literature based on the chronological order of publication. It helps to trace the development of a topic over time, showing how ideas, theories, and research have evolved.  Thematic Review: Thematic reviews focus on identifying and analyzing themes or topics that cut across different studies. Instead of organizing the literature chronologically, it is grouped by key themes or concepts, allowing for a comprehensive exploration of various aspects of the topic.  Methodological Review: This strategy involves organizing the literature based on the research methods employed in different studies. It helps to highlight the strengths and weaknesses of various methodologies and allows the reader to evaluate the reliability and validity of the research findings.  Theoretical Review: A theoretical review examines the literature based on the theoretical frameworks used in different studies. This approach helps to identify the key theories that have been applied to the topic and assess their contributions to the understanding of the subject.  It’s important to note that these strategies are not mutually exclusive, and a literature review may combine elements of more than one approach. The choice of strategy depends on the research question, the nature of the literature available, and the goals of the review. Additionally, other strategies, such as integrative reviews or systematic reviews, may be employed depending on the specific requirements of the research.

The literature review format can vary depending on the specific publication guidelines. However, there are some common elements and structures that are often followed. Here is a general guideline for the format of a literature review:  Introduction:   Provide an overview of the topic.  Define the scope and purpose of the literature review.  State the research question or objective.  Body:   Organize the literature by themes, concepts, or chronology.  Critically analyze and evaluate each source.  Discuss the strengths and weaknesses of the studies.  Highlight any methodological limitations or biases.  Identify patterns, connections, or contradictions in the existing research.  Conclusion:   Summarize the key points discussed in the literature review.  Highlight the research gap.  Address the research question or objective stated in the introduction.  Highlight the contributions of the review and suggest directions for future research.

Both annotated bibliographies and literature reviews involve the examination of scholarly sources. While annotated bibliographies focus on individual sources with brief annotations, literature reviews provide a more in-depth, integrated, and comprehensive analysis of existing literature on a specific topic. The key differences are as follows:

• Step #4: Synthesizing Content
• #5 Writing the Review
• Citing Your Sources

WRITING THE REVIEW 

You've done the research and now you're ready to put your findings down on paper. When preparing to write your review, first consider how will you organize your review.

The actual review generally has 5 components:

Abstract  -  An abstract is a summary of your literature review. It is made up of the following parts:

• A contextual sentence about your motivation behind your research topic
• Your thesis statement
• A descriptive statement about the types of literature used in the review
• Summarize your findings
• Conclusion(s) based upon your findings

Introduction :   Like a typical research paper introduction, provide the reader with a quick idea of the topic of the literature review:

• Define or identify the general topic, issue, or area of concern. This provides the reader with context for reviewing the literature.
• Identify related trends in what has already been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.
• Establish your reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope)  - 

Body :  The body of a literature review contains your discussion of sources and can be organized in 3 ways-

• Chronological -  by publication or by trend
• Thematic -  organized around a topic or issue, rather than the progression of time
• Methodical -  the focusing factor usually does not have to do with the content of the material. Instead, it focuses on the "methods" of the literature's researcher or writer that you are reviewing

You may also want to include a section on "questions for further research" and discuss what questions the review has sparked about the topic/field or offer suggestions for future studies/examinations that build on your current findings.

Conclusion :  In the conclusion, you should:

Conclude your paper by providing your reader with some perspective on the relationship between your literature review's specific topic and how it's related to it's parent discipline, scientific endeavor, or profession.

Bibliography :   Since a literature review is composed of pieces of research, it is very important that your correctly cite the literature you are reviewing, both in the reviews body as well as in a bibliography/works cited. To learn more about different citation styles, visit the " Citing Your Sources " tab.

Literature Review Tips for the Introduction and Discussion Sections

A literature review is a summary of studies related to a particular area of research. It identifies and summarizes all the relevant research conducted on a particular topic. It is important that your literature review is focused . Therefore, you should choose a limited number of studies that are central to your topic rather than trying to collect a wide range of studies that might not be closely connected.

Literature reviews help you accomplish the following:

• Evaluate past research  Collecting relevant resources will help you see what research has already been done. This will also help avoid duplication.
• Identify experts It is important to identify credible researchers who have knowledge in a given field, in order to seek their help if you get stuck with certain aspects of your research.
• Identify key questions  Your ultimate aim is to bring something new to the conversation. Collecting resources will help you determine the important questions that need to be addressed.
• Determine methodologies used in past studies Knowing how others have approached a particular topic will give you the opportunity to identify problems and find new ways to research and study a topic. If the reported methodology was successful, you can use it and save time that you would otherwise be spending on optimization.

Presenting Literature Review in the Introduction and Discussion Sections

There are many benefits to presenting literature reviews in the introduction and discussion sections of your manuscripts . However, there are differences in how you can present literature reviews in each section.

What Should be Included in the Literature Review of the Introduction Section?

The literature reviewed in the introduction should:

• Introduce the topic
• Establish the significance of the study
• Provide an overview of the relevant literature
• Establish a context for the study using the literature
• Identify knowledge gaps
• Illustrate how the study will advance knowledge on the topic

As you can see, literature review plays a significant role in the introduction section. However, there are some things that you should avoid doing in this section. These include:

• Elaborating on the studies mentioned in the literature review
• Using studies from the literature review to aggressively support your research
• Directly quoting studies from the literature review

It is important to know how to integrate the literature review into the introduction in an effective way. Although you can mention other studies, they should not be the focus. Instead, focus on using the literature review to aid in setting a foundation for the manuscript.

What Goes in the Literature Review of the Discussion Section?

Literature reviews play an important role in the discussion section of a manuscript . In this section, your findings should be the focus, rather than those of other researchers. Therefore, you should only use the studies mentioned in the literature review as support and evidence for your study.

There are three ways in which you can use literature reviews in the discussion section:

• To Provide Context for Your Study Using studies from the literature review helps to set the foundation for how you will reveal your findings and develop your ideas.
• Compare your Findings to Other Studies You can use previous literature as a backdrop to compare your new findings. This helps describe and also advance your ideas.
• State the Contribution of Your Study In addition to developing your ideas, you can use literature reviews to explain how your study contributes to the field of study.

However, there are three common mistakes that researchers make when including literature reviews in the discussion section. First, they mention all sorts of studies, some of which are not even relevant to the topic under investigation. Second, instead of citing the original article, they cite a related article that mentions the original article. Lastly, some authors cite previous work solely based on the abstract, without even going through the entire paper.

We hope this article helps you effectively present your literature review in both the introduction as well as the discussion section of your manuscript. You can also mention any other tips that will add to this article in the comments section below.

How To Structure Your Literature Review

3 options to help structure your chapter.

By: Amy Rommelspacher (PhD) | Reviewer: Dr Eunice Rautenbach | November 2020 (Updated May 2023)

Writing the literature review chapter can seem pretty daunting when you’re piecing together your dissertation or thesis. As  we’ve discussed before , a good literature review needs to achieve a few very important objectives – it should:

• Demonstrate your knowledge of the research topic
• Identify the gaps in the literature and show how your research links to these
• Provide the foundation for your conceptual framework (if you have one)
• Inform your own  methodology and research design

To achieve this, your literature review needs a well-thought-out structure . Get the structure of your literature review chapter wrong and you’ll struggle to achieve these objectives. Don’t worry though – in this post, we’ll look at how to structure your literature review for maximum impact (and marks!).

But wait – is this the right time?

Deciding on the structure of your literature review should come towards the end of the literature review process – after you have collected and digested the literature, but before you start writing the chapter. 

In other words, you need to first develop a rich understanding of the literature before you even attempt to map out a structure. There’s no use trying to develop a structure before you’ve fully wrapped your head around the existing research.

Equally importantly, you need to have a structure in place before you start writing , or your literature review will most likely end up a rambling, disjointed mess. 

Importantly, don’t feel that once you’ve defined a structure you can’t iterate on it. It’s perfectly natural to adjust as you engage in the writing process. As we’ve discussed before , writing is a way of developing your thinking, so it’s quite common for your thinking to change – and therefore, for your chapter structure to change – as you write. 

Need a helping hand?

Like any other chapter in your thesis or dissertation, your literature review needs to have a clear, logical structure. At a minimum, it should have three essential components – an  introduction , a  body   and a  conclusion . 

Let’s take a closer look at each of these.

1: The Introduction Section

Just like any good introduction, the introduction section of your literature review should introduce the purpose and layout (organisation) of the chapter. In other words, your introduction needs to give the reader a taste of what’s to come, and how you’re going to lay that out. Essentially, you should provide the reader with a high-level roadmap of your chapter to give them a taste of the journey that lies ahead.

Here’s an example of the layout visualised in a literature review introduction:

Your introduction should also outline your topic (including any tricky terminology or jargon) and provide an explanation of the scope of your literature review – in other words, what you  will   and  won’t   be covering (the delimitations ). This helps ringfence your review and achieve a clear focus . The clearer and narrower your focus, the deeper you can dive into the topic (which is typically where the magic lies). 

Depending on the nature of your project, you could also present your stance or point of view at this stage. In other words, after grappling with the literature you’ll have an opinion about what the trends and concerns are in the field as well as what’s lacking. The introduction section can then present these ideas so that it is clear to examiners that you’re aware of how your research connects with existing knowledge .

2: The Body Section

The body of your literature review is the centre of your work. This is where you’ll present, analyse, evaluate and synthesise the existing research. In other words, this is where you’re going to earn (or lose) the most marks. Therefore, it’s important to carefully think about how you will organise your discussion to present it in a clear way. 

The body of your literature review should do just as the description of this chapter suggests. It should “review” the literature – in other words, identify, analyse, and synthesise it. So, when thinking about structuring your literature review, you need to think about which structural approach will provide the best “review” for your specific type of research and objectives (we’ll get to this shortly).

There are (broadly speaking)  three options  for organising your literature review.

Option 1: Chronological (according to date)

Organising the literature chronologically is one of the simplest ways to structure your literature review. You start with what was published first and work your way through the literature until you reach the work published most recently. Pretty straightforward.

The benefit of this option is that it makes it easy to discuss the developments and debates in the field as they emerged over time. Organising your literature chronologically also allows you to highlight how specific articles or pieces of work might have changed the course of the field – in other words, which research has had the most impact . Therefore, this approach is very useful when your research is aimed at understanding how the topic has unfolded over time and is often used by scholars in the field of history. That said, this approach can be utilised by anyone that wants to explore change over time .

For example , if a student of politics is investigating how the understanding of democracy has evolved over time, they could use the chronological approach to provide a narrative that demonstrates how this understanding has changed through the ages.

Here are some questions you can ask yourself to help you structure your literature review chronologically.

• What is the earliest literature published relating to this topic?
• How has the field changed over time? Why?
• What are the most recent discoveries/theories?

In some ways, chronology plays a part whichever way you decide to structure your literature review, because you will always, to a certain extent, be analysing how the literature has developed. However, with the chronological approach, the emphasis is very firmly on how the discussion has evolved over time , as opposed to how all the literature links together (which we’ll discuss next ).

Option 2: Thematic (grouped by theme)

The thematic approach to structuring a literature review means organising your literature by theme or category – for example, by independent variables (i.e. factors that have an impact on a specific outcome).

As you’ve been collecting and synthesising literature , you’ll likely have started seeing some themes or patterns emerging. You can then use these themes or patterns as a structure for your body discussion. The thematic approach is the most common approach and is useful for structuring literature reviews in most fields.

For example, if you were researching which factors contributed towards people trusting an organisation, you might find themes such as consumers’ perceptions of an organisation’s competence, benevolence and integrity. Structuring your literature review thematically would mean structuring your literature review’s body section to discuss each of these themes, one section at a time.

Here are some questions to ask yourself when structuring your literature review by themes:

• Are there any patterns that have come to light in the literature?
• What are the central themes and categories used by the researchers?
• Do I have enough evidence of these themes?

PS – you can see an example of a thematically structured literature review in our literature review sample walkthrough video here.

Option 3: Methodological

The methodological option is a way of structuring your literature review by the research methodologies used . In other words, organising your discussion based on the angle from which each piece of research was approached – for example, qualitative , quantitative or mixed  methodologies.

Structuring your literature review by methodology can be useful if you are drawing research from a variety of disciplines and are critiquing different methodologies. The point of this approach is to question  how  existing research has been conducted, as opposed to  what  the conclusions and/or findings the research were.

For example, a sociologist might centre their research around critiquing specific fieldwork practices. Their literature review will then be a summary of the fieldwork methodologies used by different studies.

Here are some questions you can ask yourself when structuring your literature review according to methodology:

• Which methodologies have been utilised in this field?
• Which methodology is the most popular (and why)?
• What are the strengths and weaknesses of the various methodologies?
• How can the existing methodologies inform my own methodology?

3: The Conclusion Section

Once you’ve completed the body section of your literature review using one of the structural approaches we discussed above, you’ll need to “wrap up” your literature review and pull all the pieces together to set the direction for the rest of your dissertation or thesis.

The conclusion is where you’ll present the key findings of your literature review. In this section, you should emphasise the research that is especially important to your research questions and highlight the gaps that exist in the literature. Based on this, you need to make it clear what you will add to the literature – in other words, justify your own research by showing how it will help fill one or more of the gaps you just identified.

Last but not least, if it’s your intention to develop a conceptual framework for your dissertation or thesis, the conclusion section is a good place to present this.

Example: Thematically Structured Review

In the video below, we unpack a literature review chapter so that you can see an example of a thematically structure review in practice.

Let’s Recap

In this article, we’ve  discussed how to structure your literature review for maximum impact. Here’s a quick recap of what  you need to keep in mind when deciding on your literature review structure:

• Just like other chapters, your literature review needs a clear introduction , body and conclusion .
• The introduction section should provide an overview of what you will discuss in your literature review.
• The body section of your literature review can be organised by chronology , theme or methodology . The right structural approach depends on what you’re trying to achieve with your research.
• The conclusion section should draw together the key findings of your literature review and link them to your research questions.

Great work. This is exactly what I was looking for and helps a lot together with your previous post on literature review. One last thing is missing: a link to a great literature chapter of an journal article (maybe with comments of the different sections in this review chapter). Do you know any great literature review chapters?

I agree with you Marin… A great piece

I agree with Marin. This would be quite helpful if you annotate a nicely structured literature from previously published research articles.

Awesome article for my research.

I thank you immensely for this wonderful guide

It is indeed thought and supportive work for the futurist researcher and students

Very educative and good time to get guide. Thank you

Great work, very insightful. Thank you.

Thanks for this wonderful presentation. My question is that do I put all the variables into a single conceptual framework or each hypothesis will have it own conceptual framework?

Thank you very much, very helpful

This is very educative and precise . Thank you very much for dropping this kind of write up .

Pheeww, so damn helpful, thank you for this informative piece.

I’m doing a research project topic ; stool analysis for parasitic worm (enteric) worm, how do I structure it, thanks.

comprehensive explanation. Help us by pasting the URL of some good “literature review” for better understanding.

great piece. thanks for the awesome explanation. it is really worth sharing. I have a little question, if anyone can help me out, which of the options in the body of literature can be best fit if you are writing an architectural thesis that deals with design?

I am doing a research on nanofluids how can l structure it?

Beautifully clear.nThank you!

Lucid! Thankyou!

Brilliant work, well understood, many thanks

I like how this was so clear with simple language 😊😊 thank you so much 😊 for these information 😊

Insightful. I was struggling to come up with a sensible literature review but this has been really helpful. Thank you!

You have given thought-provoking information about the review of the literature.

Thank you. It has made my own research better and to impart your work to students I teach

I learnt a lot from this teaching. It’s a great piece.

I am doing research on EFL teacher motivation for his/her job. How Can I structure it? Is there any detailed template, additional to this?

You are so cool! I do not think I’ve read through something like this before. So nice to find somebody with some genuine thoughts on this issue. Seriously.. thank you for starting this up. This site is one thing that is required on the internet, someone with a little originality!

I’m asked to do conceptual, theoretical and empirical literature, and i just don’t know how to structure it

The Most Important Thing

The best time to write an introduction is AFTER you write the body of your paper.

Well, how do you know what to introduce until after you've figured out what you want to say?

The best time to write an introduction is as one of the last things you do.

Basic Introduction Template

For any other sort of scholarly writing, the following basic structure works well for an introduction:

• What has been said or done on this topic?  
• What is the problem with what has been said or done?
• What will you offer to solve the problem?  (The answer to this is your thesis statement.)
• How does your solution address necessary change?

Writing an Introduction

The job of an introduction is to preview what you are going to say so the audience knows what is coming.  A good introduction starts out generally and works towards a specific statement of what you intend to discuss in your writing. 

The introduction explains the focus and establishes the importance of the subject. It discusses what kind of work has been done on the topic and identifies any controversies within the field or any recent research which has raised questions about earlier assumptions. It may provide background or history, and it indicates why the topic is important, interesting, problematic, or relevant in some way.  It concludes with a purpose or thesis statement. In a stand-alone literature review, this statement will sum up and evaluate the state of the art in this field of research; in a review that is an introduction or preparatory to a larger work, such as the Culminating Project, it will suggest how the review findings will lead to the research the writer proposes to undertake.

In a literature review, an introduction may contain the following:

• A concise definition of a topic under consideration (this may be a descriptive or argumentative thesis, or proposal), as well as the scope of the related literature being investigated. (Example: If the topic under consideration is ‘women’s wartime diaries’, the scope of the review may be limited to published or unpublished works, works in English, works from a particular location, time period, or conflict, etc.)  
• The introduction should also note what topics are being included and what are intentional exclusions. (Example: “This review will not explore the diaries of adolescent girls.”)
• A final sentence should signal the list of key topics that will be used to discuss the selected sources.

Many theories have been proposed to explain what motivates human behavior. Although the literature covers a wide variety of such theories, this review will focus on five major themes which emerge repeatedly throughout the literature reviewed. These themes are incorporation of the self-concept into traditional theories of motivation, the influence of rewards on motivation, the increasing importance of internal forces of motivation, autonomy and self-control as sources of motivation, and narcissism as an essential component of motivation. Although the literature presents these themes in a variety of contexts, this paper will primarily focus on their application to self-motivation.

Let's break that apart.

Introductions and Literature Reviews

• Author By Troy Mikanovich

• Categories: academic journal , CARS , introduction , literature review , research , research question

Writing literature reviews is one of the trickiest things you’ll have to do in graduate school.  It is even more tricky because a lot of professors will want you to do things that are pedagogically valuable but so tailored to the specific class they are teaching that it can be hard to generalize the lessons you are meant to take away.

This page is meant to be a general overview to the goals and purposes of introductions and literature reviews (or an introduction that contains a literature review–we’ll talk about that), so even if it doesn’t exactly match what you have been asked to do in an assignment, I hope it’ll be helpful.

What is the difference between an introduction and a literature review?

As of writing this, the year is 2022 and words mean nothing. Rather than getting caught up on what these things are in some kind of objective sense, let’s look at what they are supposed to do.

The introduction and the literature review of your paper have the same job. Both are supposed to justify the question(s) you are asking about your topic and to demonstrate to your audience that the thing you are writing about is interesting and of some importance.  However, while they have the same job, they do it in two different ways.

An introduction should demonstrate that there is some broader real-world significance to the thing that you are writing about. You can do this by establishing a problem or a puzzle or by giving some background information on your topic to show why it is important.  Here’s an example from Brian E. Bride’s “Prevalence of Secondary Traumatic Stress among Social Workers” (2007, link below), where he begins by establishing a problem:

“ In the United States, the lifetime prevalence of exposure to traumatic events ranges from 40 percent to 81 percent, with 60.7 percent of men and 51.2 percent of women having been exposed to one or more traumas and 19.7 percent of men and 11.4 percent of women reporting exposure to three or more such events (Breslau, Davis, Peter-son, & Schultz, 1997; Kessler, Sonnega, Bromet, & Nelson, 1995; Stein, walker, Hazen, & Forde, 1997). Although exposure to traumatic events is high in the general population, it is even higher in subpopulations to whom social workers are likely to provide services…

Although not exhaustive of the populations with whom social workers practice, these examples illustrate that social workers face a high rate of professional contact with traumatized people. Social workers are increasingly being called on to assist survivors of childhood abuse, domestic violence, violent crime, disasters, and war and terrorism. It has become increasingly apparent that the psychological effects of traumatic events extend beyond those directly affected.”

So, Bride (2007) starts with a broad problem (lots of people with exposure to traumatic events) and narrows it to a more specific problem (social workers who work with those people are exposed to secondary trauma as they assist them) .

A literature review should demonstrate that there is some academic significance to the thing you are writing about. You can do this by establishing a scholarly problem (i.e. a “research gap”) and by demonstrating that the state of the existing scholarship on your topic needs to develop in a particular way.

As Bride (2007) transitions to talking about the scholarship on the topic of social workers and secondary trauma, he establishes what scholarship has done and identifies what it has not done .

“Figley (1999) defined secondary traumatic stress as “the natural, consequent behaviors and emotions resulting from knowledge about a traumatizing event experienced by a significant other. It is the stress resulting from helping or wanting to help a traumatized or suffering person” (p. 10). Chrestman (1999) noted that secondary traumatization includes symptoms parallel to those observed in people di-rectly exposed to trauma such as intrusive imagery related to clients’ traumatic disclosures (Courtois, 1988; Danieli, 1988; Herman, 1992; McCann & Pearlman, 1990); avoidant responses (Courtois; Haley, 1974); and physiological arousal (Figley, 1995; McCann & Pearlman, 1990). Thus, STS is a syndrome of symptoms identical to those of PTSD, the characteristic symptoms of which are intrusion, avoidance, and arousal (Figley, 1999)…

Collectively, these studies have provided empirical evidence that individuals who provide services to traumatized populations are at risk of experiencing symptoms of traumatic stress (Bride). However, the extant literature fails to document the prevalence of individual STS symptoms and the extent to which diagnostic criteria for PTSD are met as a result of work with traumatized populations.”

Taken together, Bride (2007) justifies its existence–the research that the author has undertaken in order to read the article that you are now reading–like this:

Broad real world background: Lots of people are suffering from traumatic stress.

Narrowed real world background: People who have suffered traumatic experiences often work with social workers.

Real world problem: Many social workers may through their work suffer from secondary exposure to traumatic experiences.

Broad academic background: There has been a lot of research on secondary traumatic stress

Narrowed academic background: Particularly, this research has shown that social workers are at risk of experiencing symptoms of secondary traumatic stress.

Academic problem/gap : We don’t know how prevalent individual symptoms of secondary traumatic stress are.

Introductions, then, give you space to explain why you are writing about the thing you are writing about, and literature reviews are where you explain what prior scholarship has said about the topic and what the consequences of that prior scholarship are. In an introduction you are writing about the topic; in a literature review you are writing about people writing about the topic.

So does a literature review need to be a separate section from an introduction? Or is a literature review part of an introduction?

It depends on your field, tbh. And on the expectations of the assignment/journal/outlet that you are writing for.

For instance, in the above example (Bride, 2007) the literature review is a part of the introduction. Here’s that paper and some other examples of other places where this is the case. Notice that they do not differentiate between an introductory section and a distinct “Literature Review” as they outline their topic/questions before describing their methodology:

Bride, B. E. (2007) Prevalence of secondary traumatic stress among social workers.  Social Work, 52 (1), 63-70. https://doi.org/10.1093/sw/52.1.63

Wei, X., Teng, X., Bai, J., & Ren, F. (2022). Intergenerational transmission of depression during adolescence: The mediating roles of hostile attribution bias, empathetic concern, and social self-concept.  The Journal of Psychology, 157 (1), 13-31. https://doi.org/10.1080/00223980.2022.2134276

However, plenty of other articles have distinct “Literature Review” sections separate from their introductions. The first two examples name it as such, while the third organizes its literature review with thematic sub-sections:

Schraedley, M.K., & Dougherty, D.S. (2021). Creating and disrupting othering during policymaking in a polarized context.  Journal of Communication, 72 (1), 111-140. https://doi.org/10.1093/joc/jqab042

Whether you separate your literature review into its own distinct section is mostly a function of what you’ve been asked to do (if you are writing for a class) or what the conventions and constraints are of your field.

Introduction to Literature Reviews

Introduction.

• Step One: Define
• Step Two: Research
• Step Three: Write
• Suggested Readings

A literature review is a written work that :

• Compiles significant research published on a topic by accredited scholars and researchers;
• —Surveys scholarly articles, books, dissertations, conference proceedings, and other sources;
• —Examines contrasting perspectives, theoretical approaches, methodologies, findings, results, conclusions.
• —Reviews critically, analyzes, and synthesizes existing research on a topic; and,
• Performs a thorough “re” view, “overview”, or “look again” of past and current works on a subject, issue, or theory.

From these analyses, the writer then offers an overview of the current status of a particular area of knowledge from both a practical and theoretical perspective.

Literature reviews are important because they are usually a  required  step in a thesis proposal (Master's or PhD). The proposal will not be well-supported without a literature review. Also, literature reviews are important because they help you learn important authors and ideas in your field. This is useful for your coursework and your writing. Knowing key authors also helps you become acquainted with other researchers in your field.

Look at this diagram and imagine that your research is the "something new." This shows how your research should relate to major works and other sources.

Literature Reviews

Introduction

Searching the literature

Critical reading, writing your review, citing and referencing.

• Further assistance

What is a Literature Review?

A literature review investigates and appraises existing knowledge, research, material and sources that have been published on a particular topic.  It can serve as a framework that informs the development and focus of an ensuing study, such as a thesis, article or research report. It can also be a stand-alone piece of research, such as an essay or conceptual article.

Literature reviews provide analyses that demonstrate a deep understanding of the existing literature, and commonly identify gaps and areas for future research to examine.  Importantly, literature reviews are diverse in their format and purpose:

• A literature review may be undertaken with a strong focus on critical evaluation, while others may adopt a more descriptive and exploratory approach.
• Some reviews concentrate on data, findings and methodologies, others examine ideas, themes, and theories.
• A review may aim to be summative in comprehensively synthesising all known literature on a topic. Other reviews may attempt to be more integrative in exploring related and interdisciplinary literatures.

This guide recognises the diversity of literature reviews. Rather than listing prescriptive advice, it aims to provide general guidance on the literature review process and share resources with you to help you get started.

Writing an Annotated Bibliography?

An annotated bibliography is a list of citations (articles, books, or other resources), each followed by a short descriptive paragraph that summarises the source's content and evaluates its relevance to the topic in question. For more information on how to write an annotated bibliography:

Visit the Academic Skills resource "Writing an annotated bibliography"

Writing a Systematic Review?

A systematic review appraises the literature in relation to a clearly-formulated question. It generally follows a strict protocol, with well-defined inclusion and exclusion criteria for the literature, data or studies assessed in the review, to ensure the transparency and reproducibility of the conclusions drawn by the review. To find out more about systematic reviews:

Visit the Systematic Reviews library guide

Strategies for an effective and comprehensive literature search

Maximise the quality, scope and appropriateness of the literature you review. When commencing a search:

• Determine key concepts and issues surrounding them
• Establish terminology so you can develop lists of key words and synonyms to use in your search
• Encyclopedias and key articles will often introduce topics and provide lists of key references

Reviewing a good range of the available literature on your topic is an important consideration. The tips below may be useful in helping you search for literature, and decide what literature to include in the scope of your review: 

• Consider the age of resources as appropriate for your review
• Use a variety of resources - books, journal articles, theses, conference papers and reports
• Search by keyword, subject, and also author
• Evaluate the information - is a journal refereed (peer-reviewed)? Is a source authoritative?
• Develop good referencing skills
• You can broaden your search by looking laterally for literature in related fields

Some things to consider before you start reading

• Keep your purpose in mind when you read
• Don't let the arguments in the text distract you
• Before beginning to read, take a few moments to think about what it is you are expecting from the article or chapter
• Skim-read the abstract, headings, conclusion, and the first sentence of each paragraph. Do you need to read everything with equal attention? Can you see where the arguments are headed?

Suggested critical questions to ask as you read

• What were the authors trying to discover?
• Why is this piece of research important?
• What was measured?
• What information do you have on the sample?
• How was the data collected?
• What were the results?
• What do the authors conclude and to what do they attribute their findings?
• Can you accept the findings as true?
• How can you apply these findings to your own work?

When results are conflicting, you might find it useful to ask the following questions:

• How similar were the programs used?
• Were different measurement instruments used?
• How were the programs evaluated?

Visit the Academic Skills "Reading and notetaking resources"

Structure of the review

The structure of your literature review will be based largely on your discipline and your topic. Your review is also influenced by how you decide to organise your argument(s):

• Chronological/historical
• Major authors/key studies
• Perspectives or positions taken on the topic under study
• Issues or debates (key issues/related issues)
• Methodological focus, etc.

Suggestions for structure

Organise your literature review according to an approach that best fits your topic. This means that you should not be too attached to an idea or template of how the literature review should ‘look’; instead, seek out effective models of literature reviews written in your discipline area. Broadly, the structure of a review may comprise the following elements:

• Provide an overview of the contents of the review. What is the significance and importance of the review?

Body (i.e. where you critically analyse the relevant literature)

• Synthesise the essence of literature that has dealt with your topic
• Consider any gaps or deficiencies, any inconsistencies or conflicting viewpoints and the broader implications of all this knowledge for your topic
• Draw together the important points and briefly explain how the information you have found addresses your original research question
• Indicate if more research is needed.

Important considerations

• Set parameters (e.g. inclusion and exclusion criteria for the literature referred to, date range)
• Make sure your literature review is a critical synthesis of the information you have discovered, and not just a summary
• Organise the material logically
• Make your purpose clear
• Emphasise recent/current research and developments
• Amount of detail around an issue is proportional to its importance
• Your own voice needs to be strong throughout the literature review - it needs to introduce and guide the reader through the research that is presented in the literature
• Provide commentary on design, methodology, conflicting arguments, and lack of conclusions
• Make sure citations and references are correct and accurate.

Any material you get from a source, even if you write it in your own words, needs to have a citation or footnote. Check the guidelines for your literature review, or speak to your supervisor, to determine which citation style you should be using.

What is a Literature Review?

A literature or narrative review is a comprehensive review and analysis of the published literature on a specific topic or research question. The literature that is reviewed contains: books, articles, academic articles, conference proceedings, association papers, and dissertations. It contains the most pertinent studies and points to important past and current research and practices. It provides background and context, and shows how your research will contribute to the field. 

A literature review should: 

• Provide a comprehensive and updated review of the literature;
• Explain why this review has taken place;
• Articulate a position or hypothesis;
• Acknowledge and account for conflicting and corroborating points of view

From  S age Research Methods

Purpose of a Literature Review

A literature review can be written as an introduction to a study to:

• Demonstrate how a study fills a gap in research
• Compare a study with other research that's been done

Or it can be a separate work (a research article on its own) which:

• Organizes or describes a topic
• Describes variables within a particular issue/problem

Limitations of a Literature Review

Some of the limitations of a literature review are:

• It's a snapshot in time. Unlike other reviews, this one has beginning, a middle and an end. There may be future developments that could make your work less relevant.
• It may be too focused. Some niche studies may miss the bigger picture.
• It can be difficult to be comprehensive. There is no way to make sure all the literature on a topic was considered.
• It is easy to be biased if you stick to top tier journals. There may be other places where people are publishing exemplary research. Look to open access publications and conferences to reflect a more inclusive collection. Also, make sure to include opposing views (and not just supporting evidence).

Difference Between Introduction and Literature Review

Main difference – introduction vs literature review.

Although introduction and literature review are found towards the beginning of a text, there is a difference between them in terms of their function and purpose. The main difference between introduction and literature review is their purpose; the purpose of an introduction is to briefly introduce the text to the readers whereas the purpose of a literature review is to review and critically evaluate the existing research on a selected research area. 

In this article, we will be discussing,

     1. What is an Introduction?           – Definition, Features, Characteristics

     2. What is a Literature Review?           – Definition, Features, Characteristics

What is an Introduction

An introduction is the first part of an article, paper, book or a study that briefly introduces what will be found in the following sections. An introduction basically introduces the text to the readers. It may contain various types of information, but given below some common elements that can be found in the introduction section.

• Background/context to the paper
• Outline of key issues
• Thesis statement
• Aims and purpose of the paper
• Definition of terms and concepts

Note that some introductions may not have all these elements. For example, an introduction to a short essay will only have several lines. Introductions can be found in nonfiction books, essays, research articles, thesis, etc. There can be slight variations in these various genres, but all these introductions will provide a basic outline of the whole text. 

Introduction of a thesis or dissertation will describe the background of the research, your rationale for the thesis topic, what exactly are you trying to answer, and the importance of your research.

What is a Literature Review

A literature review, which is written at the start of a research study, is essential to a research project. A literature review is an evaluation of the existing research material on a selected research area. This involves reading the major published work (both printed and online work) in a chosen research area and reviewing and critically evaluating them. A literature review should show the researcher’s awareness and insight of contrasting arguments, theories, and approaches. According to Caulley (1992) a good literature review should do the following:

• Compare and contrast different researchers’ views
• Identify areas in which researchers are in disagreement
• Group researchers who have similar conclusions
• Criticize the research methodology
• Highlight exemplary studies
• Highlight gaps in research
• Indicate the connection between your study and previous studies
• Indicate how your study will contribute to the literature in general
• Conclude by summarizing what the literature says

Literature reviews help researchers to evaluate the existing literature, to identify a gap in the research area, to place their study in the existing research and identify future research.

Introduction is at the beginning of a text.

Literature Review is located after the introduction or background.

Introduction introduces the main text to the readers.

Literature Review critically evaluates the existing research on the selected research area and identifies the research gap.

Introduction will have information such as background/context to the paper, outline of key issues, thesis statement, aims, and purpose of the paper and definition of terms and concepts. 

Literature Review will have summaries, reviews, critical evaluations, and comparisons of selected research studies.

Introduction Person-centred care (PCC) is provision of care that is respectful of and responsive to individual patient preferences, needs and values, and ensures that patient values guide all clinical decisions. While there is a large body of evidence on the benefits of PCC in high-income countries, little research exists on PCC in Ghana and Sub-Saharan Africa at large. Most studies on PCC have focused on maternity care as part of the global movement of respectful maternity care. The few studies on patient experiences and health system responsiveness beyond maternal health also highlight gaps in patient experience and satisfaction as well as discrimination in health facilities, which leads to the most vulnerable having the poorest experiences. The protocol for this scoping review aims to systematically map the extent of literature focused on PCC in Ghana by identifying patient expectations and preferences, barriers and facilitators, and interventions.

Methods and analysis The protocol will be guided by the Arksey and O’Malley methodological framework and recommendations by Levac et al . A comprehensive search strategy will be used to search for published articles in PubMed, EMBASE, Web of Science and the African Journals Online from their inception to August 2022. Grey literature and reference lists of included studies will also be searched. Two independent reviewers will perform the literature search, eligibility assessments and study selection. Any disagreements will be resolved through discussion with a third reviewer. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram for the scoping reviews will be used to outline the study selection process. Extracted data from the included articles will be synthesised and reported under key concepts derived from the outcomes of the scoping review.

Ethics and dissemination This scoping review does not require ethical approval. The findings will be disseminated through publications and conference presentations.

STRENGTHS AND LIMITATIONS OF THIS STUDY

This scoping review will use Preferred Items for Systematic reviews and Meta-analyses extension for Scoping Reviews checklist to guide the reporting of the findings.

An inclusive approach was used in developing the research questions and search strategy for this protocol.

A transdisciplinary team who bring both clinical and research experience from various fields of medicine and public health as well as in-depth knowledge of healthcare in Ghana will conduct this review.

Two independent reviewers will conduct the screening of all articles according to a prespecified set of inclusion and exclusion criteria.

Articles included in this scoping review will not be subjected to quality assessment.

Introduction

Person-centred care (PCC)—which refers to providing care that is respectful of and responsive to individual patient preferences, needs and values, and ensuring that patient values guide all clinical decisions—is a key component of quality of care. 1 Research indicates that there is a discrepancy between the healthcare sought by patients and the care patients receive. 2–4 PCC is an approach aimed at accommodating patients’ desired care to minimise this discrepancy, and emphasises treating patients with dignity and respect and involving them in all decisions about their health. 5 In addition, PCC involves providing people with the education and support they need to make decisions and participate in their own care. It also focuses on the patient’s experience of illness and healthcare and on the systems that work or fail to meet individual patient’s needs. 6

PCC requires that care is organised around the health needs and expectations of people rather than diseases: that is, focusing more on the patient’s problem than on his or her diagnosis and shifting away from asking, ‘what is the matter with you’ to ‘what matters to you’. 6 For providers, it requires qualities of compassion, empathy, communication and responsiveness to the needs, values and expressed preferences of each patient. 1

There is a large body of evidence in high-income countries such as the USA and Canada on the impact of PCC on outcomes, including health literacy, patient engagement, adherence to recommended prevention and treatment processes, emotional health, physiologic measures (such as blood pressure and blood sugar levels), pain control, symptom resolution, functional status and lower mortality. 7–9 PCC is also associated with increased preventive health screening, fewer emergency department and urgent care visits and fewer readmissions leading to higher healthcare effectiveness and lower cost. 10 In addition, PCC is associated with better patient safety and trust and higher patient as well as provider satisfaction. 9–11

Study rationale

Despite the benefits of PCC, little research exists on PCC in Ghana and most of Sub-Saharan Africa. 12 Most studies on PCC have focused on maternity care as part of the global movement of respectful maternity care. These studies have highlighted disrespect and abuse of women, poor communication and lack of respect for women’s autonomy, and lack of supportive care during childbirth. 13–15 The few studies on patient experiences and health system responsiveness beyond maternal health also highlight gaps in patient experience and satisfaction. Furthermore, these studies point out discrimination in health facilities, which leads to the most vulnerable having the poorest experiences. 16–19 From unpublished observations, patients and their carers’ in large health facilities in Ghana, such as the Korle Bu Teaching Hospital, continue to express their dissatisfaction for the care received in most of the hospital’s departments. The media in Ghana has also highlighted the state of PCC in Ghana, some of which we have witnessed as clinicians. There is, however, a dearth of systematic research on the extent of PCC in Ghana. We seek to bridge this gap by conducting a scoping review on PCC in Ghana to assess the extent of PCC in Ghana and to inform interventions to address it. From our preliminary database search, there is no prior scoping review in Ghana that addresses our study’s objectives.

Study objectives

The objectives of this scoping review are to:

Assess the extent of PCC research in Ghana.

Assess person-centeredness of care documented in Ghana.

Identify documented patient expectations and preferences for PCC in Ghana.

Identify documented barriers to PCC in Ghana.

Identify facilitators to PCC in Ghana.

Identify documented PCC interventions that have been implemented in Ghana and their effectiveness.

Identify gaps in PCC research in Ghana.

Methods and analysis

Protocol design.

This is a protocol for a scoping review of literature reporting on PCC in Ghana. A scoping review method is appropriate as it aims to delineate various types of evidence about the subject of interest and identify gaps for further research in Ghana. The review will be guided by the methodological framework proposed by Arksey and O’Malley and recommendations on the framework by Levac et al . 20 21 This scoping review will, therefore, follow these five steps: (1) identifying the research question, (2) identifying relevant studies, (3) selection of eligible studies, (4) charting the data, and (5) collating, summarising and reporting results. Quality appraisal will not be performed since the objective of this review is to get a scope of all research activities concerning PCC in Ghana.

Identifying the research question

The review questions are:

How is PCC provided in Ghana?

What are patients’ expectations and preferences regarding PCC in Ghana?

What are the barriers and facilitators to PCC in Ghana?

Are there PCC interventions that have been implemented in Ghana and how effective were they?

This study will use the Population, Intervention, Comparison and Outcome (PICO) format to align the study selection with the research question.

Identifying relevant studies

The search strategy will be designed in collaboration with an information specialist using methods previously used by other authors of systematic reviews on PCC. 22 23 Both keywords developed from core concepts and index terms Medical Subject Headings and Embase Thesaurus will be developed for the theme, PCC, and subsequently combined with Ghana in a search strategy. The search strategy for PubMed will be adapted for the other databases. The developed search strategy will be piloted to ascertain the appropriateness of keywords, which may be refined to include relevant new keywords. A proposed search strategy for PubMed is found in table 1 .

Search strategy for PubMed

The databases that will be searched for published studies include PubMed, EMBASE and Web of Science. Online supplemental appendix I provides the search strategies for PubMed, Embase and Web of Science databases. There will be no search restrictions such as publication date range, type of material or language. The databases will be searched from their inception to August 2022. The African Journals Online will be hand searched for relevant articles. Authors of retrieved studies and experts in the review’s topic area will be contacted by email to help identify additional relevant published articles and grey literature for the review. To increase the yield, backward searching of references of key articles already retrieved will be done. In addition, Google scholar will be used to identify papers that have cited identified key references in a forward search.

Supplemental material

Selection of eligible studies.

The title and abstract screening will be guided by the PICO format ( tables 2–5 ).

PICO for person-centredness of care in Ghana (objective 1)

PICO for patient expectations and preferences regarding PCC in Ghana (objective 2)

PICO for barriers and facilitators to PCC in Ghana (objective 3)

PICO for available interventions for improving PCC in Ghana (Objective 4)

Inclusion criteria:

The review is interested in all PCC in Ghana and will consider all quantitative, qualitative and mixed method studies that reported primary research findings on the review objectives. Also, grey literature with relevant findings will be included if they report on the review’s objectives and quality will not be used as a basis for inclusion or otherwise, just as for peer-reviewed articles. There will be no language restriction and translations will be sought for studies that are not published in English. Studies focused on PCC at all healthcare levels, medical specialties and health conditions in Ghana are eligible. Reviews which present primary study findings not reported elsewhere will be included. The review is interested in studies that focus on aspects of PCC such as satisfaction, perceived quality, communication, disrespect, supportive care, discrimination/stigma and abuse.

Exclusion criteria

Studies not conducted in Ghana or that do not include participants from Ghana, and studies whose full-text article cannot be obtained will be excluded.

Studies retrieved from the various databases will be exported to Covidence, ‘a web-based collaboration software platform that streamlines the production of systematic and other literature reviews’. 24 This tool will be used to remove duplicates, for title/abstract screening, full-text screening and data abstraction. Two authors will screen both titles and abstracts independently and exclude studies that do not satisfy the inclusion criteria. Two authors will then screen the full texts of the selected potentially eligible studies against the eligibility criteria. Any disagreements will be resolved through discussion with a third reviewer. Reasons for exclusion will be given for studies excluded at this stage. The selection process will be guided by the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) checklist, and a PRISMA flow diagram will be used to demonstrate the study selection process. 25 Included studies will be exported to Zotero reference manager for in-text citations. Online supplemental appendix II provides the completed PRISMA protocols 2015 statement for this protocol. 26

Charting the data

A predesigned data charting form will be used to extract relevant data from the included studies. The data charting form will first be piloted on two randomly selected studies by the two reviewers; the feedback will then be incorporated in a revision and adopted for the other included studies. The data charting form will be modified and revised during the data charting process as necessary. Data will be charted in three broad forms: qualitative studies, quantitative studies and intervention studies. Data tables will be used to summarise the relevant extracted information from the included studies. The extracted data will include, but not limited to, study ID, title of study, lead author, date of publication, study aims, geographical location, type of facility, specialty, study design, population characteristics, specific aspects or focus of PCC, instruments used, intervention and control group as well as outcomes of study. A draft extraction form is provided in online supplemental appendix III . Two authors will independently conduct the data charting process. The extracted data from the two independent authors will be compared and any differences will be resolved through consensus. Authors of studies with missing data or unclear information will be contacted for additional data or clarification through the contact details (email, phone) of the corresponding author. If this is not possible, the extent of the missing data and its potential impact on the review’s findings will be described.

Collating, summarising and reporting results

A descriptive summary of extracted data will be produced based on the following outcomes:

Primary outcomes

Person-centeredness of care (regardless of measurement approach).

Patient expectations and preferences with regards to PCC in Ghana.

Barriers and facilitators to PCC in Ghana.

Effectiveness of available interventions aimed at improving person-centred care in Ghana

Secondary outcomes

Reported health outcomes from interventions.

Stakeholder satisfaction with interventions.

Unintended adverse events from interventions.

A thematic analysis will be done for both included qualitative and quantitative studies. This will involve summarising the findings of included studies under thematic headings based on the research questions. 27

Patient and public involvement

We did not involve patients in the development of this protocol.

Ethics and dissemination

This scoping review aims to identify and describe PCC research in Ghana, identify multilevel facilitators and barriers of PCC across health contexts in Ghana as well as identify gaps in PCC research in the country. Identification of documented person-centeredness of care according to providers and patients and patient expectations and preferences with regards to PCC will help with advocacy to improve PCC and inform the development of interventions to improve PCC. Additionally, this review will provide evidence that can assist policymakers in implementing healthcare policies that centre patient needs and preferences. Furthermore, identification of various barriers and facilitators and evidence of effective PCC interventions will influence policy, practice and further research in Ghana. Therefore, the findings of this review will be disseminated among relevant Ghanaian stakeholders such as the Ministry of Health and Ghana Health Service. The findings of this study will also be published in a peer-reviewed journal and presented at conferences. The study does not require ethical approval since data will be sourced from published literature and will not involve human participants.
