Fifth, findings related to lifetime prevalence of PTSD among those exposed to different types of traumatic events were important for two reasons. Findings were consistent with previous reports that the highest conditional probabilities of PTSD are associated with events involving interpersonal violence or military combat (e.g., Breslau et al., 1998; Kessler et al., 2005; Resnick et al., 1993). Although the conditional probabilities of PTSD to interpersonal violence and combat/war related events were relatively lower than those observed in studies noted above, this may partially relate to the breadth of events assessed (e.g., broad range of physical and sexual assault), the lack of selection of index events based on symptom endorsement that is included in the methodology of some studies, and the inclusion of all event types as opposed to worst or other selected index event as the method of PTSD assessment. Similarly, the event-specific PTSD prevalence of symptoms to a given event type is narrower than the conditional risk of Same Event PTSD (to any specific event) among those with a given history of the event type (e.g., sexual or
