The DSM-5 got PTSD right: comment on Friedman (2013)

Area of Science:

• Psychiatry
• Mental Health Diagnostics
• Trauma Studies

Background:

• The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) recently revised its criteria for posttraumatic stress disorder (PTSD).
• The DSM-5 classification of PTSD within Trauma and Stressor-Related Disorders represents a significant shift.
• International Classification of Mental Disorders (ICD-11) has also proposed changes to PTSD diagnosis.

Purpose of the Study:

• To evaluate the DSM-5 PTSD diagnosis and its placement within the Trauma and Stressor-Related Disorders category.
• To compare the DSM-5 PTSD criteria with proposed changes in the ICD-11.
• To advocate for robust evidence supporting diagnostic revisions in mental health.

Main Methods:

• Analysis of the DSM-5 diagnostic process and criteria for PTSD.
• Comparative review of DSM-5 PTSD versus proposed ICD-11 criteria.
• Examination of data from web surveys supporting DSM-5 revisions.

Main Results:

• The DSM-5's placement of PTSD highlights the importance of environmental factors ('nurture') alongside genetic predispositions ('nature').
• The broader DSM-5 PTSD construct is deemed reliable and clinically significant.
• Web surveys provided crucial data supporting the DSM-5 revisions.

Conclusions:

• The DSM-5 PTSD diagnosis is a significant advancement, emphasizing psychosocial factors.
• The ICD-11's proposed changes warrant caution due to substantial differences from the validated DSM-5 criteria.
• Further evidence is required before adopting the ICD-11's divergent approach to PTSD diagnosis.
