TCE Psychology — Level 3
DSM Classification — Flashcards & Quiz
The Diagnostic and Statistical Manual (DSM) is the standard reference for classifying mental disorders. TCE Psychology Level 3 uses it to define abnormal behaviour and asks you to explain diagnostic criteria, compare categorical vs dimensional approaches, and critically evaluate the DSM's strengths (standardisation) and weaknesses (stigma, cultural bias, reliability).
Key Points
- DSM classifies disorders by symptom clusters (categorical approach): a person either meets the criteria or doesn't.
- Each diagnosis has specific inclusion criteria (symptoms that must be present), duration requirements, and exclusion criteria.
- Strengths: standardised diagnosis enables communication between clinicians, research comparability, and insurance/legal clarity.
- Weaknesses: categorical boundaries are arbitrary (someone just below threshold may still need help), stigma attached to labels, cultural and gender biases in criteria.
- Dimensional approach (proposed): disorders as continuous traits rather than discrete categories — better captures real variation but harder for clinical decisions.
- DSM-5 added cross-cutting symptom measures and removed the multi-axial system, moving slightly toward a dimensional approach.
Common Mistakes to Avoid
- Treating DSM as the only classification system — ICD (international) is also widely used.
- Confusing categorical (either/or) with dimensional (continuous) approaches.
- Ignoring the stigma and cultural bias critiques when asked to evaluate.
- Claiming DSM is the cause of mental illness — it's a tool for diagnosis, not creation.
- Forgetting reliability and validity concerns in evaluation responses.
Exam Strategy
TASC Level 3 abnormal psychology questions ask you to describe DSM structure or evaluate the classification system. Method: (1) explain the categorical approach with examples, (2) describe strengths (standardisation, communication), (3) evaluate weaknesses (stigma, cultural bias, reliability), (4) discuss dimensional alternatives, (5) conclude with a qualified judgement.
Sample Flashcards
Q1: What is the DSM-5 and what are its strengths and limitations?
The DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition) is published by the American Psychiatric Association and provides standardised criteria for diagnosing mental disorders. Strengths: improves diagnostic reliability, facilitates communication between clinicians, supports research. Limitations: may medicalise normal behaviour, categorical rather than dimensional, cultural bias (Western-centric), influenced by pharmaceutical industry interests.
Sample Quiz Questions
Q1: The DSM-5 is published by the World Health Organisation and is the only classification system for mental disorders.
Answer: FALSE
The DSM-5 is published by the American Psychiatric Association (APA). The World Health Organisation publishes the ICD (International Classification of Diseases), which is a separate and widely used classification system. Both systems classify mental disorders but differ in their criteria and structure.
Revision Tip
DSM evaluation is a balanced argument — drill a Revizi deck pairing each strength with a weakness for structured response practice.
