Lifetime DSM-5 PTSD prevalence varied as a function of the type of Criterion A event (see Table 5). Consistent with prior research, prevalence was highest among victims of interpersonal violence and combat. Prevalence of Same Event PTSD according to the DSM-5 among those reporting exposure to any DSM-5 Criterion A event was 9.3%. Same Event and Composite Event PTSD prevalence increased as a function of numbers of DSM-5 Criterion A event types experienced (see Figure 1).
