Overall, conditional risk of PTSD, given exposure to a trauma, was 15.9%, ranging between 8.7% for NP males and 22.2% for SW females. Comparable figures from DAST were 13.8% overall, 9.2% for men, and 16.5% for women [17]. Baseline NCS rates were 8.1% for men and 20.4% for women [3]. Generally, then, conditional rates of PTSD among these three studies were similar, both overall and by gender.
