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, 152 subjects have completed baseline interviews 6, 12, and 24 month interviews have been completed for 110, 66, and 24 participants respectively. Preliminary findings from analyses of 100 baseline and 81 6 month follow-ups show that while 17 met full criteria for PTSD, over half reported 3 or more symptoms of PTSD at baseline, with symptoms of hyperarousal the most common. Total CAPS scores decrease significantly from baseline to 6 and 12 months rates of remission for individual symptoms were variable, ranging from 3 to 36. PTSD symptoms were significantly associated with psychosocial impairment. Psychosocial variables showing significant associations with PTSD include pre-deployment trauma, severity of warzone trauma exposure, lower post-deployment social support, and higher post-deployment life stress.
