TASK NUMBER E-Mail:5f. WORK UNIT NUMBER The primary research aims are to examine the early longitudinal course of PTSD symptoms and test hypotheses regarding risk factors for chronic PTSD in military personnel returning from Iraq or Afghanistan. To date, 238 subjects have completed baseline interviews; 6, 12, and 24 month interviews have been completed for 177, 131, and 62 participants respectively. Data processing is continuing. Of 179 participants with processed data, 13% met full criteria for PTSD; 40% reported 3 or more symptoms of PTSD at month one postdeployment. Symptoms of hyperarousal were the most common. Total scores from the Clinician Assessment of PTSD Scale (CAPS) decreased significantly from month one to month 6 post-deployment. 18% had a current diagnosis of a mood disorder, and 9% had current alcohol abuse or dependence. PTSD symptom clusters of numbing / avoidance and hyperarousal were significantly associated with psychosocial impairment, controlling for the presence of other Axis I disorders. Psychosocial variables showing significant associations with PTSD included pre-deployment trauma, severity of warzone trauma exposure, several features of the deployment environment, lower post-deployment social support, and higher post-deployment life stress. Further assessments and data processing will continue over the next 3 months, and data analyses will be conducted to address the specific hypotheses on the fuller sample.
