Psychiatry's problem child: PTSD in the forensic context: (part 1).

Area of Science:

• Forensic Psychiatry
• Psychopathology
• Legal Medicine

Background:

• Post-traumatic stress disorder (PTSD) diagnosis in forensic contexts is questioned.
• Concerns exist regarding the application of diagnostic criteria, particularly Criterion A(1).
• This may lead to an inflated prevalence of PTSD in litigation.

Purpose of the Study:

• To review literature questioning PTSD prevalence in forensic settings.
• To examine the application of the stressor criterion (Criterion A) in forensic evaluations.
• To assess potential biases and errors in forensic PTSD diagnoses.

Main Methods:

• Review of literature concerning the PTSD stressor criterion from DSM-III to DSM-IV-TR.
• Analysis of studies addressing the application of this criterion in forensic contexts.
• Examination of the implications for PTSD prevalence in legal cases.

Main Results:

• The nature of the stressor required for PTSD diagnosis has remained consistent since DSM-III.
• Despite this, PTSD is widely diagnosed in forensic settings, contrasting with its rarity in objective clinical studies.
• The potential for malingering PTSD symptoms for secondary gain (e.g., benefits) is recognized.

Conclusions:

• PTSD's ubiquity in forensic contexts may stem from its association with benefits and potential for simulation.
• Some forensic psychiatric evaluations may lack the rigor of clinical assessments.
• The utility of PTSD as a clinical diagnosis warrants reconsideration, especially with ongoing discussions for DSM-V.
