Finally, in addition to number of traumas, we also examined type of trauma as a predictor of the conditional risk of PTSD. We conducted a second logistic regression using the same demographic predictors mentioned above (i.e., group status, gender, ethnicity, education, income) and also included 5 different categories of trauma: rape /sexual assault, other assaultive violence, witnessing trauma to others, non-violent trauma, and other trauma. An individual could report any or all of these different traumatic experiences. In this multivariate analysis, the prediction of PTSD differed by exposure to the different types of traumatic experiences. Those who experienced either sexual assault or other assaultive violence were two and a half times more likely to have PTSD than those who did not experience these types of trauma (see Table 5). Witnessing trauma to others, experiencing other trauma, and being female were also significant predictors of conditional risk of PTSD.
