title: An examination of the differential effects of the experience of DSM-IV defined traumatic events and life stressors.
abstract: Recent evidence suggests that individuals exposed to traumatic events report similar, if not lower, levels of posttraumatic stress disorder (PTSD) symptoms than individuals exposed to nontraumatic stressful life events [J. Anxiety Disord. 19 (2005) 687-698; Br. J. Psychiatry 186 (2005) 494-499]. The current study compared the level of self-reported PTSD symptoms in a large sample (n=668) of trauma and nontrauma exposed college students. Participants were assessed for past trauma history as well as current symptoms of PTSD, depression, social interaction anxiety, and current positive and negative affect. Results indicated that while those who had experienced a traumatic event reported statistically significantly higher levels of PTSD symptoms, these differences were no longer clinically significant after other psychological distress factors were accounted for. Additional analyses suggested that those who had experienced events of an interpersonal nature had significantly higher levels of PTSD symptoms than those who had experienced other types of events.
