EssayFount's psychology hub publishes free worked case study examples, biopsychosocial assessment templates, CBT case conceptualizations, DSM-5 diagnostic vignettes and AP Psychology review materials, all written or peer-reviewed by credentialed clinical and research psychologists. Every example shows the reasoning behind the diagnosis, formulation, or research design so undergraduate, masters and doctoral students can apply the same logic to their own coursework and practicum write-ups.
Authored by Dr. Clara Bennett, PsyD Clinical Psychology, with twelve years teaching case formulation and abnormal psychology at the doctoral level. Peer-reviewed by Dr. Rohan Mehta, PhD Industrial Organizational Psychology, with fifteen years teaching research methods and psychometrics. Last reviewed April 2026.
How students use the EssayFount psychology hub
Across the past twelve months, 64 verified writing experts holding a Master of Arts, Master of Science, PsyD or PhD in clinical, counseling, developmental, forensic or industrial organizational psychology contributed to this hub. Together they produced 192 fully annotated case study examples, 38 reproducible research-method walk-throughs, and 410 AP Psychology practice items aligned to the College Board 2024-2025 Course and Exam Description. Traffic concentrates in three predictable windows: the week before mid-term exams, the practicum case-presentation cycle in graduate clinical programs, and the May AP Psychology review run.
Every clinical example passes a two-tier review. A subject-matter writer holding a doctorate or terminal masters drafts each formulation; a second senior psychologist verifies the diagnostic reasoning against the Diagnostic and Statistical Manual of Mental Disorders, fifth edition text revision (American Psychiatric Association, 2022) and confirms the cited evidence base before publication. Quantitative research-method examples receive an additional methodological audit from the reviewer to confirm correct statistical reporting per the Publication Manual of the American Psychological Association, seventh edition. Read more about our writers study materials and the credential verification process behind every byline.
The hub complements rather than replaces a course. Students should still complete required reading in Comer and Comer's Abnormal Psychology, Cozby and Bates's Methods in Behavioral Research, or Kazdin's Research Design in Clinical Psychology, attempt their assigned case write-ups unaided, and bring questions to faculty supervisors. When a formulation framework or statistical method does not click, the page gives a second explanation with a fully annotated worked example.

Psychology case study examples
A psychology case study is a structured narrative of one client, one organization, or one social unit that integrates presenting concerns, history, assessment data and formulation into a single document a clinician, supervisor, or course instructor can act on. Course assignments most often ask for one of three formats: a biopsychosocial assessment, a cognitive behavioral therapy (CBT) case conceptualization, or a brief DSM-5 diagnostic vignette followed by a treatment plan. Each format has its own audience and its own evidentiary standard.
Annotated biopsychosocial assessment example
The biopsychosocial model, introduced by Engel (1977) and refined for psychology training by Sperry (2010), organizes case data into three interacting domains. Below is a 320-word annotated excerpt that doctoral practicum students can adapt. The bracketed margin notes show the reasoning behind each clinical move.
Identifying information. "Maya" is a 24-year-old multiracial cisgender woman, second-year graduate student in social work, presenting at a university counseling center for an intake assessment after self-referral following two weeks of insomnia, tearfulness and a panic attack during a class presentation. [Identifying data is anonymized and limited to demographic and contextual variables relevant to formulation; per the APA Ethics Code Standard 4.07, identifying details that are not clinically necessary are removed.]
Biological domain. Maya reports broken sleep averaging four hours nightly, elevated resting heart rate during her panic attack, no current substance use, no current psychotropic medication and a maternal family history of generalized anxiety disorder. Recent thyroid panel obtained from her primary care physician was within normal limits. [A complete biological review rules in or out medical contributors before psychological formulation. The thyroid panel addresses one of the most common medical mimics of anxiety per the National Institute of Mental Health (NIMH) clinical reference for differential workup.]
Psychological domain. On the Patient Health Questionnaire 9, Maya scored 14 (moderate depression); on the Generalized Anxiety Disorder 7 scale she scored 16 (severe). She describes intrusive worry about academic performance, perfectionistic standards, and a long-standing pattern of avoidance of public speaking dating to a humiliating middle-school presentation. [Standardized self-report measures provide a reproducible severity baseline for treatment outcome monitoring per the Clinical Practice Guideline of the American Psychological Association on the treatment of depression in adults (APA, 2019).]
Social domain. Maya recently relocated for graduate school, reports limited local social support, financial strain from a teaching assistantship below cost of living, and ongoing supportive contact with her mother by weekly phone call. [The social section captures protective and risk factors, both of which inform the formulation and treatment plan.]
Integrative formulation (one paragraph). Maya presents with comorbid moderate major depressive disorder and severe generalized anxiety disorder, predisposed by familial loading and perfectionism, precipitated by graduate-school transition and isolation, perpetuated by avoidance of evaluative situations and sleep dysregulation, and protected by intact family support, intact reality testing and prior academic success.
Note the four-P structure (predisposing, precipitating, perpetuating, protective) in the integrative paragraph. Sperry (2010) identifies the four-Ps as the minimum acceptable formulation depth for a doctoral-level case write-up; instructors at counseling psychology programs typically dock points if any of the four is missing.
Annotated CBT case conceptualization example
A CBT case conceptualization moves beyond description into a testable hypothesis about how a client's beliefs, behaviors, and physiological responses maintain the presenting problem. The Beck Institute's standard format (J. Beck, 2021) requires a written cognitive conceptualization diagram before treatment-planning. The annotated example below shows one such diagram in narrative form for a 280-word excerpt.
Presenting problem. "Daniel," a 31-year-old software engineer, presents with social anxiety in client-facing meetings, with avoidance behaviors that are now affecting his performance review.
Relevant childhood data. Daniel was the youngest of three siblings; his older sisters frequently mocked his speech in family settings, and his father praised academic but not interpersonal achievement. [Childhood data is the developmental ground for core beliefs per Beck (2021) Cognitive Conceptualization Diagram, but is included only when the client identifies it as personally meaningful, to avoid speculative reconstruction.]
Core belief. "I am incompetent in social settings."
Conditional assumptions. "If I speak in a meeting, others will judge me." "If I am judged, I will lose respect." "If I lose respect, I will be fired."
Compensatory strategies. Over-preparation, declining to speak unless directly addressed, mentally rehearsing every sentence before speaking. [Compensatory strategies are the behaviors that protect against the feared outcome but maintain the core belief by preventing disconfirmation, per Beck (2021).]
Situation, automatic thought, emotion, behavior chain (one example). Situation: Daniel is asked to summarize a project status in a Monday client meeting. Automatic thought: "I will say something stupid and they will replace me on the account." Emotion: anxiety, rated 85 of 100. Behavior: he reads verbatim from a printed script, avoids eye contact, and ends the summary forty seconds early.
Treatment hypothesis. Cognitive restructuring of the conditional assumption "if I am judged I will lose respect" combined with behavioral experiments (graded exposure to unscripted speaking) is hypothesized to disconfirm the core belief over twelve sessions.
This conceptualization meets the Cognitive Therapy Rating Scale criterion for a passing case formulation (Young and Beck, 1980; updated 2021). Course graders looking at a CBT vignette typically check for: a clearly stated core belief, three to five conditional assumptions, identifiable compensatory strategies, and a falsifiable treatment hypothesis.
Annotated DSM-5 diagnostic vignette
A DSM-5 diagnostic vignette is a brief narrative followed by a multi-axial style summary of diagnostic codes; abnormal psychology and psychopathology courses use the vignette to assess differential reasoning. The 245-word example below shows one common format.
Vignette. "Reza," a 19-year-old undergraduate, presents to the campus health center reporting two months of depressed mood most of the day on most days, loss of interest in his usual hobbies, weight loss of nine pounds without dieting, early-morning awakening at 4 a.m., persistent feelings of guilt over a recent breakup, and difficulty concentrating in lectures. He denies current suicidal ideation, plan or intent, denies past psychiatric history, denies medical comorbidity, denies substance use beyond occasional caffeine. He has missed five class meetings in the past three weeks and is at risk of academic probation.
Differential consideration. Persistent depressive disorder requires two years duration, ruled out. Adjustment disorder with depressed mood is plausible given the breakup but the symptom count meets the major depressive disorder threshold, which takes diagnostic precedence per DSM-5-TR Section II hierarchy.
Diagnostic impression. Major depressive disorder, single episode, moderate, without psychotic features (DSM-5-TR code F32.1). No co-occurring substance use disorder. No medical condition contributing.
Treatment recommendation. Cognitive behavioral therapy weekly for sixteen sessions per the APA Clinical Practice Guideline for adult depression (APA, 2019), referral to primary care for medication evaluation, behavioral activation homework starting in session one, suicide-risk reassessment at every visit using the Columbia Suicide Severity Rating Scale.
Vignettes of this length appear on most undergraduate abnormal psychology midterms and on the National Clinical Mental Health Counseling Examination case items. Graders look for the right code, the correct severity specifier, and an evidence-based treatment recommendation linked to a specific guideline.
Treatment plans and intervention write-ups
A treatment plan translates the case formulation into measurable goals, objectives, interventions and review intervals. The Joint Commission and most state Medicaid plans require a written treatment plan within three sessions of intake. Counseling psychology, social work, and rehabilitation counseling courses ask students to draft treatment plans following a standardized SMART-goal structure (Specific, Measurable, Achievable, Relevant, Time-bound).
A typical doctoral-quality treatment plan for the Maya case above would include three goals. Goal one: reduce PHQ-9 score from 14 to under 5 within twelve weeks, with weekly behavioral activation and cognitive restructuring sessions and biweekly self-monitoring. Goal two: reduce GAD-7 score from 16 to under 8 within sixteen weeks, using exposure hierarchies and applied relaxation. Goal three: re-establish a daily sleep schedule of seven to eight hours within six weeks, using stimulus control and sleep restriction protocols per the American Academy of Sleep Medicine Clinical Practice Guideline (Edinger et al., 2021).
Each goal pairs with at least one intervention drawn from a randomized controlled trial or clinical practice guideline. Course graders dock points when interventions are listed without source citations, when goals are not measurable, or when the review interval is missing. The intervention list should also specify who delivers it, how often, and how progress is documented.
Research methods in psychology
Research methods in psychology coursework, typically a 300-level required course in undergraduate psychology programs, asks students to design, critique and report empirical studies. The four design families that appear in nearly every research methods syllabus are experimental, quasi-experimental, correlational and qualitative.
Experimental designs
True experimental designs randomly assign participants to at least two conditions, manipulate an independent variable, and measure a dependent variable. The classical between-subjects randomized controlled design remains the gold standard for causal inference per Shadish, Cook and Campbell (2002). Within-subjects (repeated-measures) designs and mixed factorial designs trade higher statistical power for added internal validity threats from order and carryover effects, addressed through counterbalancing.
Quasi-experimental designs
Quasi-experimental designs include nonequivalent control groups, interrupted time series, and regression discontinuity. They are common in school psychology, community psychology and applied behavior analysis where random assignment is impractical or unethical. The interrupted time series with a comparison series is the strongest quasi-experimental design per Shadish, Cook and Campbell (2002), provided the analyst models autocorrelation properly.
Correlational and survey designs
Correlational designs measure two or more variables on each participant and quantify their statistical association. They are widely used in personality, social and developmental psychology where the variables of interest cannot be manipulated. Standard reporting requires effect sizes (Pearson r or Spearman rho), confidence intervals, and discussion of common-method bias when the same instrument captures predictor and outcome.
Qualitative designs
Qualitative designs include phenomenological, grounded theory, case study, narrative and ethnographic approaches. They produce rich, contextual descriptions of human experience and are appropriate when the research question concerns meaning rather than frequency or magnitude. The Consolidated Criteria for Reporting Qualitative Research (COREQ; Tong, Sainsbury and Craig, 2007) provides a 32-item reporting standard widely adopted in psychology journals.
For statistical analysis support across any of these designs, see our statistics pillar essay examples for SPSS and R worked examples and our data science pillar homework help for advanced regression, machine learning and reproducible analysis pipelines.
Developmental psychology cases
Developmental psychology courses use case studies to teach Piagetian, Eriksonian, Vygotskian and contemporary cognitive-developmental frameworks. A typical assignment asks the student to observe a child of a specified age, document one developmental milestone in narrative form, and link the observation to two competing theoretical frameworks.
The hub publishes annotated examples for the four-month neonatal social smile, the eighteen-month object permanence completion, the four-year theory-of-mind transition (false-belief task), the eight-year concrete-operational reasoning, the fourteen-year identity exploration, and the early-twenties emerging adulthood transition (Arnett, 2000). Each example shows the observation, two theoretical interpretations, and a paragraph explaining why one framework better fits the observed data.
For students drafting the literature review section that anchors a developmental research paper paper assistance, see our literature review format pillar writing guide for the standard graduate structure.
Industrial organizational psychology
Industrial organizational (I-O) psychology applies psychological science to workplace problems including selection, performance management, training, leadership and organizational change. I-O coursework draws heavily on case studies of selection-system validation, job-analysis, structured interview design and engagement survey interpretation.
The hub publishes worked examples for the criterion-related validation of a customer-service selection battery, a competency-based job analysis for a software-engineering manager role, a behavioral-anchored rating scale for clinical-supervisor performance review, and a structural-equation model of an employee engagement survey. Each example aligns with the Society for Industrial and Organizational Psychology Principles for the Validation and Use of Personnel Selection Procedures, fifth edition (2018).
Students taking I-O courses should also reference Cascio and Aguinis's Applied Psychology in Talent Management and the Annual Review of Organizational Psychology and Organizational Behavior for current empirical work.
Forensic and clinical-legal psychology
Forensic psychology courses ask students to draft mock competency to stand trial evaluations, sanity at the time of offense reports, and risk assessments for violence or sexual recidivism. The hub publishes redacted, fully fictional teaching examples of competency reports following the Grisso (2003) framework, sanity reports addressing Massachusetts and Federal standards, and structured professional judgment risk reports using the Historical Clinical Risk-20 third version (Douglas, Hart, Webster and Belfrage, 2013).
Each example flags ethical and legal landmines: dual-relationship risk, the duty to warn following the Tarasoff rulings, the Marsy's Law victim-notification requirement in some states, and limits to confidentiality when court-ordered. Students producing a forensic case write-up for course credit should never use real client material, even with redaction; the hub examples are constructed from composite teaching scenarios.
AP Psychology practice and review
AP Psychology is one of the College Board's largest examinations, with over 280,000 candidates taking it each May per the most recent published participation report. The 2024-2025 Course and Exam Description redistributed weighting across the nine units, with the largest weight on Cognitive Psychology and Biological Psychology. The hub publishes 410 multiple-choice review items, eight free-response question samples with annotated graders' rubrics, and a unit-by-unit topic outline aligned to the current CED.
Students preparing for AP Psychology benefit from spaced retrieval (Roediger and Karpicke, 2006) and from practicing free-response questions under timed conditions before the May administration. The hub's free-response samples each show the question stem, an exemplary response, and the College Board scoring rubric scored at the 6 of 7 and 7 of 7 levels with explicit rubric annotations.
Real-world examples and credit-eligible work
The hub's case studies and research-method examples are teaching materials. They are not substitutes for licensed clinical supervision, and students must never represent a hub example as their own assessment of a real client. Programs that allow case-based assignments require a signed academic-integrity statement; the hub's examples are designed to model the format, the depth and the citation discipline of doctoral-quality work, not to be turned in as the student's own.
For students who need a fully written, original case formulation or research-paper draft created from their own course-specific instructions and rubric, our psychology assignment writing service assigns a credentialed writer with a doctorate in clinical, counseling or research psychology and produces a model document students can study, annotate, and rewrite in their own voice. For graduate dissertation chapters in psychology, our intro to dissertation writing service study materials matches doctoral writers with subject-matter expertise to the proposed methodology.
How we choose the writers behind every example
Every psychology contributor passes a four-step credentialing process. First, terminal-degree verification through a National Student Clearinghouse or international equivalent transcript review. Second, sample-task review where the candidate produces one biopsychosocial assessment, one CBT conceptualization and one APA-formatted research-method critique, scored independently by two existing senior writers against a published rubric. Third, ethics screening for the APA Ethical Principles of Psychologists and Code of Conduct, the relevant state licensure-board requirements where applicable, and an attestation that no contributor has an open ethics complaint. Fourth, ongoing peer-review across the lifespan of every contribution, with random spot-checks of cited evidence by a senior reviewer holding a PhD and at least ten years of teaching experience.
The senior reviewer for this hub, Dr. Rohan Mehta, additionally audits all quantitative claims in the research-methods section against original sources before publication. Where a cited claim cannot be traced to its primary source within fifteen minutes of review, the citation is removed and the claim is rewritten or cut.
