• Pros and Cons

What Types of Case Studies Are Out There?

Where do you find data for a case study, how do i write a psychology case study.

A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in many different fields, including psychology, medicine, education, anthropology, political science, and social work.

The point of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.

While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, we got you—here are some rules of APA format to reference.  

At a Glance

A case study, or an in-depth study of a person, group, or event, can be a useful research tool when used wisely. In many cases, case studies are best used in situations where it would be difficult or impossible for you to conduct an experiment. They are helpful for looking at unique situations and allow researchers to gather a lot of˜ information about a specific individual or group of people. However, it's important to be cautious of any bias we draw from them as they are highly subjective.

What Are the Benefits and Limitations of Case Studies?

A case study can have its strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.

One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult or impossible to replicate in a lab. Some other benefits of a case study:

• Allows researchers to capture information on the 'how,' 'what,' and 'why,' of something that's implemented
• Gives researchers the chance to collect information on why one strategy might be chosen over another
• Permits researchers to develop hypotheses that can be explored in experimental research

On the other hand, a case study can have some drawbacks:

• It cannot necessarily be generalized to the larger population
• Cannot demonstrate cause and effect
• It may not be scientifically rigorous
• It can lead to bias

Researchers may choose to perform a case study if they want to explore a unique or recently discovered phenomenon. Through their insights, researchers develop additional ideas and study questions that might be explored in future studies.

It's important to remember that the insights from case studies cannot be used to determine cause-and-effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.

Case Study Examples

There have been a number of notable case studies in the history of psychology. Much of  Freud's work and theories were developed through individual case studies. Some great examples of case studies in psychology include:

• Anna O : Anna O. was a pseudonym of a woman named Bertha Pappenheim, a patient of a physician named Josef Breuer. While she was never a patient of Freud's, Freud and Breuer discussed her case extensively. The woman was experiencing symptoms of a condition that was then known as hysteria and found that talking about her problems helped relieve her symptoms. Her case played an important part in the development of talk therapy as an approach to mental health treatment.
• Phineas Gage : Phineas Gage was a railroad employee who experienced a terrible accident in which an explosion sent a metal rod through his skull, damaging important portions of his brain. Gage recovered from his accident but was left with serious changes in both personality and behavior.
• Genie : Genie was a young girl subjected to horrific abuse and isolation. The case study of Genie allowed researchers to study whether language learning was possible, even after missing critical periods for language development. Her case also served as an example of how scientific research may interfere with treatment and lead to further abuse of vulnerable individuals.

Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie's case, her horrific abuse denied her the opportunity to learn a language at critical points in her development.

This is clearly not something researchers could ethically replicate, but conducting a case study on Genie allowed researchers to study phenomena that are otherwise impossible to reproduce.

There are a few different types of case studies that psychologists and other researchers might use:

• Collective case studies : These involve studying a group of individuals. Researchers might study a group of people in a certain setting or look at an entire community. For example, psychologists might explore how access to resources in a community has affected the collective mental well-being of those who live there.
• Descriptive case studies : These involve starting with a descriptive theory. The subjects are then observed, and the information gathered is compared to the pre-existing theory.
• Explanatory case studies : These   are often used to do causal investigations. In other words, researchers are interested in looking at factors that may have caused certain things to occur.
• Exploratory case studies : These are sometimes used as a prelude to further, more in-depth research. This allows researchers to gather more information before developing their research questions and hypotheses .
• Instrumental case studies : These occur when the individual or group allows researchers to understand more than what is initially obvious to observers.
• Intrinsic case studies : This type of case study is when the researcher has a personal interest in the case. Jean Piaget's observations of his own children are good examples of how an intrinsic case study can contribute to the development of a psychological theory.

The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.

The type of case study that psychology researchers use depends on the unique characteristics of the situation and the case itself.

There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:

• Archival records : Census records, survey records, and name lists are examples of archival records.
• Direct observation : This strategy involves observing the subject, often in a natural setting . While an individual observer is sometimes used, it is more common to utilize a group of observers.
• Documents : Letters, newspaper articles, administrative records, etc., are the types of documents often used as sources.
• Interviews : Interviews are one of the most important methods for gathering information in case studies. An interview can involve structured survey questions or more open-ended questions.
• Participant observation : When the researcher serves as a participant in events and observes the actions and outcomes, it is called participant observation.
• Physical artifacts : Tools, objects, instruments, and other artifacts are often observed during a direct observation of the subject.

If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines you need to follow. If you are writing your case study for a professional publication, check with the publisher for their specific guidelines for submitting a case study.

Here is a general outline of what should be included in a case study.

Section 1: A Case History

This section will have the following structure and content:

Background information : The first section of your paper will present your client's background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.

Description of the presenting problem : In the next section of your case study, you will describe the problem or symptoms that the client presented with.

Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.

Your diagnosis : Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client's symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.

Section 2: Treatment Plan

This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.

• Cognitive behavioral approach : Explain how a cognitive behavioral therapist would approach treatment. Offer background information on cognitive behavioral therapy and describe the treatment sessions, client response, and outcome of this type of treatment. Make note of any difficulties or successes encountered by your client during treatment.
• Humanistic approach : Describe a humanistic approach that could be used to treat your client, such as client-centered therapy . Provide information on the type of treatment you chose, the client's reaction to the treatment, and the end result of this approach. Explain why the treatment was successful or unsuccessful.
• Psychoanalytic approach : Describe how a psychoanalytic therapist would view the client's problem. Provide some background on the psychoanalytic approach and cite relevant references. Explain how psychoanalytic therapy would be used to treat the client, how the client would respond to therapy, and the effectiveness of this treatment approach.
• Pharmacological approach : If treatment primarily involves the use of medications, explain which medications were used and why. Provide background on the effectiveness of these medications and how monotherapy may compare with an approach that combines medications with therapy or other treatments.

This section of a case study should also include information about the treatment goals, process, and outcomes.

When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research. 

In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?

Need More Tips?

Here are a few additional pointers to keep in mind when formatting your case study:

• Never refer to the subject of your case study as "the client." Instead, use their name or a pseudonym.
• Read examples of case studies to gain an idea about the style and format.
• Remember to use APA format when citing references .

Case studies are in-depth investigations of a person, group, event, or community. Typically, data is gathered from various sources using several methods (e.g., observations & interviews).

The case study research method originated in clinical medicine (the case history, i.e., the patient’s personal history). In psychology, case studies are often confined to the study of a particular individual.

The information is mainly biographical and relates to events in the individual’s past (i.e., retrospective), as well as to significant events that are currently occurring in his or her everyday life.

The case study is not a research method, but researchers select methods of data collection and analysis that will generate material suitable for case studies.

Freud (1909a, 1909b) conducted very detailed investigations into the private lives of his patients in an attempt to both understand and help them overcome their illnesses.

This makes it clear that the case study is a method that should only be used by a psychologist, therapist, or psychiatrist, i.e., someone with a professional qualification.

There is an ethical issue of competence. Only someone qualified to diagnose and treat a person can conduct a formal case study relating to atypical (i.e., abnormal) behavior or atypical development.

 Famous Case Studies

• Anna O – One of the most famous case studies, documenting psychoanalyst Josef Breuer’s treatment of “Anna O” (real name Bertha Pappenheim) for hysteria in the late 1800s using early psychoanalytic theory.
• Little Hans – A child psychoanalysis case study published by Sigmund Freud in 1909 analyzing his five-year-old patient Herbert Graf’s house phobia as related to the Oedipus complex.
• Bruce/Brenda – Gender identity case of the boy (Bruce) whose botched circumcision led psychologist John Money to advise gender reassignment and raise him as a girl (Brenda) in the 1960s.
• Genie Wiley – Linguistics/psychological development case of the victim of extreme isolation abuse who was studied in 1970s California for effects of early language deprivation on acquiring speech later in life.
• Phineas Gage – One of the most famous neuropsychology case studies analyzes personality changes in railroad worker Phineas Gage after an 1848 brain injury involving a tamping iron piercing his skull.

Clinical Case Studies

• Studying the effectiveness of psychotherapy approaches with an individual patient
• Assessing and treating mental illnesses like depression, anxiety disorders, PTSD
• Neuropsychological cases investigating brain injuries or disorders

Child Psychology Case Studies

• Studying psychological development from birth through adolescence
• Cases of learning disabilities, autism spectrum disorders, ADHD
• Effects of trauma, abuse, deprivation on development

Types of Case Studies

• Explanatory case studies : Used to explore causation in order to find underlying principles. Helpful for doing qualitative analysis to explain presumed causal links.
• Exploratory case studies : Used to explore situations where an intervention being evaluated has no clear set of outcomes. It helps define questions and hypotheses for future research.
• Descriptive case studies : Describe an intervention or phenomenon and the real-life context in which it occurred. It is helpful for illustrating certain topics within an evaluation.
• Multiple-case studies : Used to explore differences between cases and replicate findings across cases. Helpful for comparing and contrasting specific cases.
• Intrinsic : Used to gain a better understanding of a particular case. Helpful for capturing the complexity of a single case.
• Collective : Used to explore a general phenomenon using multiple case studies. Helpful for jointly studying a group of cases in order to inquire into the phenomenon.

Where Do You Find Data for a Case Study?

There are several places to find data for a case study. The key is to gather data from multiple sources to get a complete picture of the case and corroborate facts or findings through triangulation of evidence. Most of this information is likely qualitative (i.e., verbal description rather than measurement), but the psychologist might also collect numerical data.

1. Primary sources

• Interviews – Interviewing key people related to the case to get their perspectives and insights. The interview is an extremely effective procedure for obtaining information about an individual, and it may be used to collect comments from the person’s friends, parents, employer, workmates, and others who have a good knowledge of the person, as well as to obtain facts from the person him or herself.
• Observations – Observing behaviors, interactions, processes, etc., related to the case as they unfold in real-time.
• Documents & Records – Reviewing private documents, diaries, public records, correspondence, meeting minutes, etc., relevant to the case.

2. Secondary sources

• News/Media – News coverage of events related to the case study.
• Academic articles – Journal articles, dissertations etc. that discuss the case.
• Government reports – Official data and records related to the case context.
• Books/films – Books, documentaries or films discussing the case.

3. Archival records

Searching historical archives, museum collections and databases to find relevant documents, visual/audio records related to the case history and context.

Public archives like newspapers, organizational records, photographic collections could all include potentially relevant pieces of information to shed light on attitudes, cultural perspectives, common practices and historical contexts related to psychology.

4. Organizational records

Organizational records offer the advantage of often having large datasets collected over time that can reveal or confirm psychological insights.

Of course, privacy and ethical concerns regarding confidential data must be navigated carefully.

However, with proper protocols, organizational records can provide invaluable context and empirical depth to qualitative case studies exploring the intersection of psychology and organizations.

• Organizational/industrial psychology research : Organizational records like employee surveys, turnover/retention data, policies, incident reports etc. may provide insight into topics like job satisfaction, workplace culture and dynamics, leadership issues, employee behaviors etc.
• Clinical psychology : Therapists/hospitals may grant access to anonymized medical records to study aspects like assessments, diagnoses, treatment plans etc. This could shed light on clinical practices.
• School psychology : Studies could utilize anonymized student records like test scores, grades, disciplinary issues, and counseling referrals to study child development, learning barriers, effectiveness of support programs, and more.

How do I Write a Case Study in Psychology?

Follow specified case study guidelines provided by a journal or your psychology tutor. General components of clinical case studies include: background, symptoms, assessments, diagnosis, treatment, and outcomes. Interpreting the information means the researcher decides what to include or leave out. A good case study should always clarify which information is the factual description and which is an inference or the researcher’s opinion.

1. Introduction

• Provide background on the case context and why it is of interest, presenting background information like demographics, relevant history, and presenting problem.
• Compare briefly to similar published cases if applicable. Clearly state the focus/importance of the case.

2. Case Presentation

• Describe the presenting problem in detail, including symptoms, duration,and impact on daily life.
• Include client demographics like age and gender, information about social relationships, and mental health history.
• Describe all physical, emotional, and/or sensory symptoms reported by the client.
• Use patient quotes to describe the initial complaint verbatim. Follow with full-sentence summaries of relevant history details gathered, including key components that led to a working diagnosis.
• Summarize clinical exam results, namely orthopedic/neurological tests, imaging, lab tests, etc. Note actual results rather than subjective conclusions. Provide images if clearly reproducible/anonymized.
• Clearly state the working diagnosis or clinical impression before transitioning to management.

3. Management and Outcome

• Indicate the total duration of care and number of treatments given over what timeframe. Use specific names/descriptions for any therapies/interventions applied.
• Present the results of the intervention,including any quantitative or qualitative data collected.
• For outcomes, utilize visual analog scales for pain, medication usage logs, etc., if possible. Include patient self-reports of improvement/worsening of symptoms. Note the reason for discharge/end of care.

4. Discussion

• Analyze the case, exploring contributing factors, limitations of the study, and connections to existing research.
• Analyze the effectiveness of the intervention,considering factors like participant adherence, limitations of the study, and potential alternative explanations for the results.
• Identify any questions raised in the case analysis and relate insights to established theories and current research if applicable. Avoid definitive claims about physiological explanations.
• Offer clinical implications, and suggest future research directions.

5. Additional Items

• Thank specific assistants for writing support only. No patient acknowledgments.
• References should directly support any key claims or quotes included.
• Use tables/figures/images only if substantially informative. Include permissions and legends/explanatory notes.
• Provides detailed (rich qualitative) information.
• Provides insight for further research.
• Permitting investigation of otherwise impractical (or unethical) situations.

Case studies allow a researcher to investigate a topic in far more detail than might be possible if they were trying to deal with a large number of research participants (nomothetic approach) with the aim of ‘averaging’.

Because of their in-depth, multi-sided approach, case studies often shed light on aspects of human thinking and behavior that would be unethical or impractical to study in other ways.

Research that only looks into the measurable aspects of human behavior is not likely to give us insights into the subjective dimension of experience, which is important to psychoanalytic and humanistic psychologists.

Case studies are often used in exploratory research. They can help us generate new ideas (that might be tested by other methods). They are an important way of illustrating theories and can help show how different aspects of a person’s life are related to each other.

The method is, therefore, important for psychologists who adopt a holistic point of view (i.e., humanistic psychologists ).

Limitations

• Lacking scientific rigor and providing little basis for generalization of results to the wider population.
• Researchers’ own subjective feelings may influence the case study (researcher bias).
• Difficult to replicate.
• Time-consuming and expensive.
• The volume of data, together with the time restrictions in place, impacted the depth of analysis that was possible within the available resources.

Because a case study deals with only one person/event/group, we can never be sure if the case study investigated is representative of the wider body of “similar” instances. This means the conclusions drawn from a particular case may not be transferable to other settings.

Because case studies are based on the analysis of qualitative (i.e., descriptive) data , a lot depends on the psychologist’s interpretation of the information she has acquired.

This means that there is a lot of scope for Anna O , and it could be that the subjective opinions of the psychologist intrude in the assessment of what the data means.

For example, Freud has been criticized for producing case studies in which the information was sometimes distorted to fit particular behavioral theories (e.g., Little Hans ).

This is also true of Money’s interpretation of the Bruce/Brenda case study (Diamond, 1997) when he ignored evidence that went against his theory.

What Is a Case Study? | Definition, Examples & Methods

Published on May 8, 2019 by Shona McCombes . Revised on November 20, 2023.

A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.

A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating and understanding different aspects of a research problem .

Table of contents

When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyze the case, other interesting articles.

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.

Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.

You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.

Prevent plagiarism. Run a free check.

Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:

• Provide new or unexpected insights into the subject
• Challenge or complicate existing assumptions and theories
• Propose practical courses of action to resolve a problem
• Open up new directions for future research

TipIf your research is more practical in nature and aims to simultaneously investigate an issue as you solve it, consider conducting action research instead.

Unlike quantitative or experimental research , a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.

Example of an outlying case studyIn the 1960s the town of Roseto, Pennsylvania was discovered to have extremely low rates of heart disease compared to the US average. It became an important case study for understanding previously neglected causes of heart disease.

However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.

Example of a representative case studyIn the 1920s, two sociologists used Muncie, Indiana as a case study of a typical American city that supposedly exemplified the changing culture of the US at the time.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:

• Exemplify a theory by showing how it explains the case under investigation
• Expand on a theory by uncovering new concepts and ideas that need to be incorporated
• Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions

To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.

There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews , observations , and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.

Example of a mixed methods case studyFor a case study of a wind farm development in a rural area, you could collect quantitative data on employment rates and business revenue, collect qualitative data on local people’s perceptions and experiences, and analyze local and national media coverage of the development.

The aim is to gain as thorough an understanding as possible of the case and its context.

In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis , with separate sections or chapters for the methods , results and discussion .

Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications (for example, by using textual analysis or discourse analysis ).

In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

How to Write a Case Conceptualization: 10 Examples (+ PDF)

Such understanding can be developed by reading relevant records, meeting with clients face to face, and using assessments such as a mental status examination.

As you proceed, you are forming a guiding concept of who this client is, how they became who they are, and where their personal journey might be heading.

Such a guiding concept, which will shape any needed interventions, is called a case conceptualization, and we will examine various examples in this article.

In psychology and related fields, a case conceptualization summarizes the key facts and findings from an evaluation to provide guidance for recommendations.

This is typically the evaluation of an individual, although you can extend the concept of case conceptualization to summarizing findings about a group or organization.

Based on the case conceptualization, recommendations can be made to improve a client’s self-care , mental status, job performance, etc (Sperry & Sperry, 2020).

• Summary of the client’s identifying information, referral questions, and timeline of important events or factors in their life . A timeline can be especially helpful in understanding how the client’s strengths and limitations have evolved.
• Statement of the client’s core strengths . Identifying core strengths in the client’s life should help guide any recommendations, including how strengths might be used to offset limitations.
• Statement concerning a client’s limitations or weaknesses . This will also help guide any recommendations. If a weakness is worth mentioning in a case conceptualization, it is worth writing a recommendation about it.

Note: As with mental status examinations , observations in this context concerning weaknesses are not value judgments, about whether the client is a good person, etc. The observations are clinical judgments meant to guide recommendations.

• A summary of how the strengths, limitations, and other key information about a client inform diagnosis and prognosis .

You should briefly clarify how you arrived at a given diagnosis. For example, why do you believe a personality disorder is primary, rather than a major depressive disorder?

Many clinicians provide diagnoses in formal psychiatric terms, per the International Classification of Diseases (ICD-10) or Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Some clinicians will state a diagnosis in less formal terms that do not coincide exactly with ICD-10 or DSM-5 codes. What is arguably more important is that a diagnostic impression, formal or not, gives a clear sense of who the person is and the support they need to reach their goals.

Prognosis is a forecast about whether the client’s condition can be expected to improve, worsen, or remain stable. Prognosis can be difficult, as it often depends on unforeseeable factors. However, this should not keep you from offering a conservative opinion on a client’s expected course, provided treatment recommendations are followed.

This is a 15-year-old Haitian–American youth, referred by his mother for concerns about self-isolation, depression, and poor social skills. He reportedly moved with his mother to the United States three years ago.

He reportedly misses his life and friends in Haiti. The mother states he has had difficulty adjusting socially in the United States, especially with peers. He has become increasingly self-isolating, appears sad and irritable, and has started to refuse to go to school.

His mother is very supportive and aware of his emotional–behavioral needs. The youth has been enrolled in a social skills group at school and has attended three sessions, with some reported benefit. He is agreeable to start individual counseling. He reportedly does well in school academically when he applies himself.

Limitations

Behavioral form completed by his mother shows elevated depression scale (T score = 80). There is a milder elevation on the inattention scale (T score = 60), which suggests depression is more acute than inattention and might drive it.

He is also elevated on a scale measuring social skills and involvement (T score = 65). Here too, it is reasonable to assume that depression is driving social isolation and difficulty relating to peers, especially since while living in Haiti, he was reportedly quite social with peers.

Diagnostic impressions, treatment guidance, prognosis

This youth’s history, presentation on interview, and results of emotional–behavioral forms suggest some difficulty with depression, likely contributing to social isolation. As he has no prior reported history of depression, this is most likely a reaction to missing his former home and difficulty adjusting to his new school and peers.

Treatments should include individual counseling with an evidence-based approach such as Cognitive-Behavioral Therapy (CBT). His counselor should consider emotional processing and social skills building as well.

Prognosis is favorable, with anticipated benefit apparent within 12 sessions of CBT.

How to write a case conceptualization: An outline

The following outline is necessarily general. It can be modified as needed, with points excluded or added, depending on the case.

• Client’s gender, age, level of education, vocational status, marital status
• Referred by whom, why, and for what type of service (e.g., testing, counseling, coaching)
• In the spirit of strengths-based assessment, consider listing the client’s strengths first, before any limitations.
• Consider the full range of positive factors supporting the client.
• Physical health
• Family support
• Financial resources
• Capacity to work
• Resilience or other positive personality traits
• Emotional stability
• Cognitive strengths, per history and testing
• The client’s limitations or relative weaknesses should be described in a way that highlights those most needing attention or treatment.
• Medical conditions affecting daily functioning
• Lack of family or other social support
• Limited financial resources
• Inability to find or hold suitable employment
• Substance abuse or dependence
• Proneness to interpersonal conflict
• Emotional–behavioral problems, including anxious or depressive symptoms
• Cognitive deficits, per history and testing
• Diagnoses that are warranted can be given in either DSM-5 or ICD-10 terms.
• There can be more than one diagnosis given. If that’s the case, consider describing these in terms of primary diagnosis, secondary diagnosis, etc.
• The primary diagnosis should best encompass the client’s key symptoms or traits, best explain their behavior, or most need treatment.
• Take care to avoid over-assigning multiple and potentially overlapping diagnoses.

When writing a case conceptualization, always keep in mind the timeline of significant events or factors in the examinee’s life.

• Decide which events or factors are significant enough to include in a case conceptualization.
• When these points are placed in a timeline, they help you understand how the person has evolved to become who they are now.
• A good timeline can also help you understand which factors in a person’s life might be causative for others. For example, if a person has suffered a frontal head injury in the past year, this might help explain their changeable moods, presence of depressive disorder, etc.

Sample #1: Conceptualization for CBT case

This is a 35-year-old Caucasian man referred by his physician for treatment of generalized anxiety.

Strengths/supports in his case include willingness to engage in treatment, high average intelligence per recent cognitive testing, supportive family, and regular physical exercise (running).

Limiting factors include relatively low stress coping skills, frequent migraines (likely stress related), and relative social isolation (partly due to some anxiety about social skills).

The client’s presentation on interview and review of medical/psychiatric records show a history of chronic worry, including frequent worries about his wife’s health and his finances. He meets criteria for DSM-5 generalized anxiety disorder. He has also described occasional panic-type episodes, which do not currently meet full criteria for panic disorder but could develop into such without preventive therapy.

Treatments should include CBT for generalized anxiety, including keeping a worry journal; regular assessment of anxiety levels with Penn State Worry Questionnaire and/or Beck Anxiety Inventory; cognitive restructuring around negative beliefs that reinforce anxiety; and practice of relaxation techniques, such as progressive muscle relaxation and diaphragmatic breathing .

Prognosis is good, given the evidence for efficacy of CBT for anxiety disorders generally (Hofmann, Asnaani, Vonk, Sawyer, & Fang, 2012).

Sample #2: Conceptualization for DBT case

This 51-year-old Haitian–American woman is self-referred for depressive symptoms, including reported moods of “rage,” “sadness,” and “emptiness.” She says that many of her difficulties involve family, friends, and coworkers who regularly “disrespect” her and “plot against her behind her back.”

Her current psychiatrist has diagnosed her with personality disorder with borderline features, but she doubts the accuracy of this diagnosis.

Strengths/supports include a willingness to engage in treatment, highly developed and marketable computer programming skills, and engagement in leisure activities such as playing backgammon with friends.

Limiting factors include low stress coping skills, mild difficulties with attention and recent memory (likely due in part to depressive affect), and a tendency to self-medicate with alcohol when feeling depressed.

The client’s presentation on interview, review of medical/psychiatric records, and results of MMPI-2 personality inventory corroborate her psychiatrist’s diagnosis of borderline personality disorder.

The diagnosis is supported by a longstanding history of unstable identity, volatile personal relationships with fear of being abandoned, feelings of emptiness, reactive depressive disorder with suicidal gestures, and lack of insight into interpersonal difficulties that have resulted in her often stressed and depressive state.

Treatments should emphasize a DBT group that her psychiatrist has encouraged her to attend but to which she has not yet gone. There should also be regular individual counseling emphasizing DBT skills including mindfulness or present moment focus, building interpersonal skills, emotional regulation, and distress tolerance. There should be a counseling element for limiting alcohol use. Cognitive exercises are also recommended.

Of note, DBT is the only evidence-based treatment for borderline personality disorder (May, Richardi, & Barth, 2016). Prognosis is guardedly optimistic, provided she engages in both group and individual DBT treatments on a weekly basis, and these treatments continue without interruption for at least three months, with refresher sessions as needed.

Sample #3: Conceptualization in a family therapy case

This 45-year-old African-American woman was initially referred for individual therapy for “rapid mood swings” and a tendency to become embroiled in family conflicts. Several sessions of family therapy also appear indicated, and her psychiatrist concurs.

The client’s husband (50 years old) and son (25 years old, living with parents) were interviewed separately and together. When interviewed separately, her husband and son each indicated the client’s alcohol intake was “out of control,” and that she was consuming about six alcoholic beverages throughout the day, sometimes more.

Her husband and son each said the client was often too tired for household duties by the evening and often had rapid shifts in mood from happy to angry to “crying in her room.”

On individual interview, the client stated that her husband and son were each drinking about as much as she, that neither ever offered to help her with household duties, and that her son appeared unable to keep a job, which left him home most of the day, making demands on her for meals, etc.

On interview with the three family members, each acknowledged that the instances above were occurring at home, although father and son tended to blame most of the problems, including son’s difficulty maintaining employment, on the client and her drinking.

Strengths/supports in the family include a willingness of each member to engage in family sessions, awareness of supportive resources such as assistance for son’s job search, and a willingness by all to examine and reduce alcohol use by all family members as needed.

Limiting factors in this case include apparent tendency of all household members to drink to some excess, lack of insight by one or more family members as to how alcohol consumption is contributing to communication and other problems in the household, and a tendency by husband and son to make this client the family scapegoat.

The family dynamic can be conceptualized in this case through a DBT lens.

From this perspective, problems develop within the family when the environment is experienced by one or more members as invalidating and unsupportive. DBT skills with a nonjudgmental focus, active listening to others, reflecting each other’s feelings, and tolerance of distress in the moment should help to develop an environment that supports all family members and facilitates effective communication.

It appears that all family members in this case would benefit from engaging in the above DBT skills, to support and communicate with one another.

Prognosis is guardedly optimistic if family will engage in therapy with DBT elements for at least six sessions (with refresher sessions as needed).

17 Science-Based Ways To Apply Positive CBT

These 17 Positive CBT & Cognitive Therapy Exercises [PDF] include our top-rated, ready-made templates for helping others develop more helpful thoughts and behaviors in response to challenges, while broadening the scope of traditional CBT.

Created by Experts. 100% Science-based.

The following resources can be found in the Positive Psychology Toolkit© , and their full versions can be accessed by a subscription.

Analyzing Strengths Use in Different Life Domains can help clients understand their notable strengths and which strengths can be used to more advantage in new contexts.

Family Strength Spotting is another relevant resource. Each family member fills out a worksheet detailing notable strengths of other family members. In reviewing all worksheets, each family member can gain a greater appreciation for other members’ strengths, note common or unique strengths, and determine how best to use these combined strengths to achieve family goals.

Four Front Assessment is another resource designed to help counselors conceptualize a case based on a client’s personal and environmental strengths and weaknesses. The idea behind this tool is that environmental factors in the broad sense, such as a supportive/unsupportive family, are too often overlooked in conceptualizing a case.

In helping professions, success in working with clients depends first and foremost on how well you understand them.

This understanding is crystallized in a case conceptualization.

Case conceptualization helps answer key questions. Who is this client? How did they become who they are? What supports do they need to reach their goals?

The conceptualization itself depends on gathering all pertinent data on a given case, through record review, interview, behavioral observation, questionnaires completed by the client, etc.

Once the data is assembled, the counselor, coach, or other involved professional can focus on enumerating the client’s strengths, weaknesses, and limitations.

It is also often helpful to put the client’s strengths and limitations in a timeline so you can see how they have evolved and which factors might have contributed to the emergence of others.

Based on this in-depth understanding of the client, you can then tailor specific recommendations for enhancing their strengths, overcoming their weaknesses, and reaching their particular goals.
