The prevalence of self-reported exposure to traumatic events is given in Table 1. Some enrichment for childhood trauma (see eTable 4 for comparison), consistent with the sample’s ascertainment based on twins’ report of CSA or CPA, is evident, as is enrichment for psychiatric disorders (see eTable 2). The risk of PTSD associated with nomination of each specific event as the most disturbing (Table 2) exhibits a fairly consistent pattern in which higher risk is observed for assaultive and severe childhood trauma. One surprising exception is the relatively modest PTSD risk observed for combat exposure, the least prevalent event for both men and women.
