Indeed, gender is critical to understanding PTSD prevalence. Breslau and colleagues [26,27] have written extensively about the gender differentials in PTSD prevalence found in DAST and other studies. Typically, men have reported higher levels of trauma than women, accompanied by lower rates of PTSD. In contrast, in AI-SUPERPFP, men and women reported comparable levels of trauma exposure [6]. Furthermore, although a gender differential existed in conditional rates of PTSD, the odds ratios for gender were considerably smaller among AI-SUPERPFP participants than in either NCS and DAST [2,3]. When we parse the findings by event category, an interesting difference emerges between DAST and AI-SUPERPFP. In both instances, conditional rates of PTSD associated with interpersonal trauma were typically twice those of other trauma types [2]. However, whereas DAST reported a strong gender differential in conditional PTSD for interpersonal trauma [26], this gender difference was not statistically significant in the American Indian samples as seen in Table 3, nor were the interactions between gender and event type significant when examined in preparation for Table 4. This finding may be interpretable in view of
