Summary
The post-traumatic stress disorder (PTSD) diagnosis, while useful, has conceptual issues with its trauma criterion (A-criterion). Revising this criterion may improve clarity and avoid misleading causal attributions in PTSD research.
Area of Science:
- Psychiatry
- Psychology
- Mental Health Research
Background:
- Post-traumatic stress disorder (PTSD) has been a significant diagnosis since 1980.
- Its clinical utility and heuristic value are widely recognized in practice and research.
Purpose of the Study:
- To critically evaluate the conceptual difficulties associated with the PTSD diagnosis.
- To examine the A-criterion (trauma criterion) of PTSD and its impact on understanding the disorder's etiology.
Main Methods:
- Conceptual analysis of the Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria for PTSD.
- Review of the historical and theoretical underpinnings of the PTSD diagnosis, particularly the A-criterion.
Main Results:
- The A-criterion, stipulating a monocausal etiology, is considered inadequate, misleading, and tautological.
- This criterion is influenced by social and political factors rather than purely scientific ones.
Conclusions:
- Omitting the A-criterion and defining PTSD based on descriptive, phenomenological terms is proposed.
- This approach aims to prevent confusion regarding causal attributions in PTSD.
