Title

The Utility of the Personality Assessment Inventory in the Assessment of Posttraumatic Stress Disorder in OEF/OIF/OND Veterans

Abstract

We examined the use of the Personality Assessment Inventory (PAI) in a small sample of 47 U.S. military veterans of the conflicts in Iraq and Afghanistan. Approximately half of the sample met criteria for posttraumatic stress disorder (PTSD) based on the Clinician-Administered PTSD Scale. PAI profiles were compared between the PTSD and non-PTSD groups. The PTSD group had clinically significant scores (≥ 70T) on the PAI for 5 clinical scales (anxiety, anxiety-related disorders, depression, paranoia, and schizophrenia) and 10 clinical subscales consistent with the typical symptom picture for PTSD. Effect size correlations (r) between scales and diagnosis group membership were large (r ≥.5) for several scales that reflect PTSD symptoms and for the PTSD LOGIT function. In a receiver operating characteristics curve analysis, the PTSD LOGIT function and the Traumatic Stress Subscale both demonstrated good diagnostic utility (areas under the curve >.80).
