Evaluation of the 4 D’s
Strengths:
•reliability
>standard test to assess symptoms
•reliability
>clinician should explore all 4 D’s for higher reliability
Weaknesses:
• reliability
> diagnosis relies on what is discussed
> measures over deviance should be standardized
- Potential for subjectivity in interpretation
- for “Deviance” = some issues are not rare, e.g: depression
Classification systems

- Diagnostic and Statistical Manual of Mental Disorders (DSM)
~ the purpose is to lead to a better-quality diagnosis
~ Not universally accepted
~ Several influential critics of these systems
~ minimize issues of reliability + validity that come from interpretation diagnosis
