Text

Although the primary analyses focused on graded TE and PTSD variables to capture variability in trauma exposure and PTSD symptoms, analyses also were conducted with binary variables for comparison to prior research and to provide information on these relationships from a diagnostic perspective. In the full sample, lifetime prevalence of trauma exposure was 83.7%; lifetime prevalence of PTSD was 13.5% (full PTSD [5.4%] and partial PTSD [8.1%]).. Similar to the main results, AD was related to binary TE/PTSD, except that the percentage of the TE effect explained by PTSD was lower (24.0%; Table 3. ND was related to binary TE/PTSD, and the percentage explained by PTSD was also lower (24.6%). Finally,. MD was similarly related to binary PTSD and not TE.
