Of the total NESARC wave 2 (when PTSD was assessed) (n = 34 653), 8.7% experienced sexual assault, 16.5%, severe accidents, 15.7%, disaster and 41.6%, unexpected death of someone close. Table 1 presents the numbers of persons exposed to each of these events and the numbers in each index event on which the conditional percentages of PTSD are based. The probability of PTSD associated with sexual assault was 40.2%, markedly higher than the PTSD probability associated with each of the comparison events (Table 1) or any other traumatic event in NESARC (Breslau et al. 2010). For sexual assault and for each of the three comparison events, females’ PTSD risk was higher than males’.
