5.2% of US veterans tested positive for DSM-5 PTSD from the previous month. The best dimensional representation of DSM-5 PTSD symptom clusters is provided by a 6-factor model of symptoms that builds on existing models and adds a sixth externalizing behavior factor. This model also showed validity in evaluating health outcomes of relevance in this population.
What is DSM-5?
- The American Psychiatric Association's taxonomy and diagnostic manual, Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), was updated in 2013 to reflect current research (APA).
- The DSM is the leading source of psychiatric diagnoses in the United States.
- DSM classifications are frequently used to guide treatment recommendations and decide how much healthcare professionals are paid, therefore the release of a new version has real-world implications.
- The DSM-5 is the only DSM that uses an Arabic number in place of a Roman number in its title. It is also the only DSM that is a live document.
The National Health and Resilience in Veterans Study, a nationally representative survey of 1,484 US veterans conducted from September to October 2013, provided the data for this analysis.
- Confirmatory factor analyses of PTSD symptoms were carried out to determine their factor structure, and structural equation models were built to investigate the relationship between clusters of PTSD symptoms and their external correlates.
- 5.2% and 12.0% of veterans with recent PTSD, respectively, tested positive on screenings.
- The data were much better suited by a 5-factor dysphoric arousal model and a recently proposed 6-factor model than by the DSM-5's 4-factor model.
- The entire sample, as well as subsamples of female veterans and veterans with lifetime PTSD, showed the best data fit with the 6-factor model.
