DSM-5, psychiatric epidemiology and the false positives problem.

Area of Science:

• Psychiatry
• Mental Health Diagnostics
• Scientific Publishing

Background:

• The Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) underwent a revision process.
• Criticism has been leveled at the DSM-5's revision process, goals, and outcomes.
• Concerns exist regarding the transparency and rationale behind diagnostic changes.

Purpose of the Study:

• To critically evaluate the revision process, goals, and outcomes of the DSM-5.
• To examine the impact of DSM-5's diagnostic criteria on research validity, particularly concerning false positives.
• To illustrate specific examples of problematic diagnostic expansions in the DSM-5.

Main Methods:

• Critical analysis of the DSM-5 revision process.
• Review of stated goals for the DSM-5 revision.
• Examination of the DSM-5's approach to the false positives problem.
• Case examples illustrating diagnostic expansion and potential issues.

Main Results:

• The DSM-5 revision process lacked transparency and adequate public record of rationale.
• Key revision goals, such as dimensionalizing diagnosis, were largely abandoned.
• The DSM-5 failed to adequately address the problem of diagnostic false positives.
• Specific diagnostic changes, including for substance use disorder and major depression, are criticized for expanding criteria inappropriately.

Conclusions:

• The DSM-5 revision was flawed in process, goals, and outcome.
• The failure to address false positives threatens the validity of psychiatric research and epidemiology.
• Specific diagnostic expansions in DSM-5 require re-evaluation to ensure diagnostic accuracy and research integrity.
