Prolonged Exposure (PE) is an evidenced-based psychotherapy for posttraumatic stress disorder (PTSD) that is being disseminated nationally within the U.S. Department of Veterans Affairs (VA) with promising initial results. Empirical evidence, however, regarding the effectiveness of PE for treatment of PTSD in military veterans is limited. Building on previous treatment outcome research, the current study investigated the effectiveness of PE in a diverse veteran sample. One-hundred fifteen veterans were enrolled in PE at an urban VA medical center and its surrounding outpatient clinics. PTSD and depression symptoms as well as quality of life were measured before and after treatment. Several baseline patient characteristics were examined as predictors of treatment response. Eighty-four participants completed treatment. Participants experienced a 42% reduction in PTSD symptoms, a 31% reduction in depression symptoms, and an increase in quality of life following PE. Veterans not prescribed psychotropic medication reported greater PTSD symptom reduction than veterans prescribed such medication. The implications of these results for treatment programs targeting PTSD in veterans are discussed.
