Although posttraumatic stress disorder (PTSD) factor analytic research has yielded little support for the DSM-IV 3-factor model of reexperiencing, avoidance, and hyperarousal symptoms, no clear consensus regarding alternative models has emerged. One possible explanation is differential instrumentation across studies. In the present study, the authors used confirmatory factor analysis to compare a self-report measure, the PTSD Checklist (PCL), and a structured clinical interview, the Clinician-Administered PTSD Scale (CAPS), in 2,960 utility workers exposed to the World Trade Center Ground Zero site. Although two 4-factor models fit adequately for each measure, the latent structure of the PCL was slightly better represented by correlated reexperiencing, avoidance, dysphoria, and hyperarousal factors, whereas that of the CAPS was slightly better represented by correlated reexperiencing, avoidance, emotional numbing, and hyperarousal factors. After accounting for method variance, the model specifying dysphoria as a distinct factor achieved slightly better fit. Patterns of correlations with external variables provided additional support for the dysphoria model. Implications regarding the underlying structure of PTSD are discussed.

This study assessed self and interpersonal dysfunction as well as posttraumatic stress disorder (PTSD) among three groups of women: women sexually assaulted in both childhood and adulthood, women sexually assaulted only in adulthood and women who were never assaulted. Rates of PTSD were high and equivalent in the two assault groups. However, retraumatized women were more likely to be alexithymic, show dissociation scores indicating risk for dissociative disorders, and to have attempted suicide compared to the other two groups, who did not differ from each other. Additionally, only the retraumatized women experienced clinically significant levels of interpersonal problems. The findings suggest that formulations more inclusive than PTSD are required to capture the psychological difficulties experienced by this population. Treatment implications are discussed.

PE is an efficacious treatment for active-duty Army soldiers with PTSD from deployments to Iraq or Afghanistan. Results extend previous evidence supporting the efficacy of PE to active-duty military personnel and raise important questions for future research on VRE. (PsycINFO Database Record
