Investigators Develop Diagnostic Guidelines for Post-Traumatic Stress Disorder


Diagnosing mental disorders is often challenging, but may be especially difficult in post-traumatic stress disorder (PTSD) due to the high rates of comorbidity between PTSD and other psychiatric disorders. Moreover, there are several problematic diagnostic questions: How do mental health care providers distinguish symptoms of agoraphobia from avoidance symptoms of PTSD? How do we differentiate overlapping symptoms of PTSD and depressive disorders? And, when are hallucinations symptomatic of PTSD versus an independent psychotic disorder? In order to answer these and other important diagnostic questions, investigators in this study interviewed 115 male Veterans with combat-related PTSD and depressive disorders who were enrolled in a randomized clinical trial comparing self-management therapy versus psycho-educational group therapy.

As a result of this study, investigators offer guidelines for the differential diagnosis of Veterans with PTSD. For example, avoidance of certain places or situations should not necessarily count as a symptom of both agoraphobia and PTSD. Assessment of the reason for the avoidance behavior should determine which disorder better accounts for it. Hallucinations that were strongly related to the theme of a traumatic experience were considered to be a re-experiencing symptom of PTSD (flashback) rather than an indication of a separate psychotic disorder. Therefore, clinicians should be aware that those suffering from PTSD might present with symptoms that initially point to other diagnoses, and that mistaken diagnoses can have detrimental effects. Of particular concern is the possibility that PTSD-related hallucinations may be seen as a primary psychotic process. Investigators believe that the guidelines they offer can lead to greater reliability in the diagnosis of PTSD and related comorbid conditions.

What are HSR&D Publication Briefs?

HSR&D requires notification by HSR&D-funded investigators about all articles accepted for publication. These journal articles are reviewed by HSR&D and publication briefs or summaries are written for a select number of articles that are then forwarded to VHA Central Office leadership to keep them informed about important findings or information. Articles to be summarized are selected by HSR&D based on timeliness of the findings, interest of leadership, or potential impact on the organization. Publication briefs are written for only a small number of HSR&D published articles. Visit the HSR&D citations database for a complete listing of HSR&D articles and presentations.
