title: Latent Factor Structure ofDSM-5Posttraumatic Stress Disorder.
abstract: The current study examined the latent factor structure of posttraumatic stress disorder (PTSD) based onDSM-5criteria in a sample of participants (N= 374) recruited for studies on trauma and health. Confirmatory factor analyses (CFA) were used to compare the fit of the previous 3-factorDSM-IVmodel of PTSD to the 4-factor model specified inDSM-5as well as to a competing 4-factor "dysphoria" model (Simms, Watson, & Doebbeling, 2002) and a 5-factor (Elhai et al., 2011) model of PTSD. Results indicated that the Elhai 5-factor model (re-experiencing, active avoidance, emotional numbing, dysphoric arousal, anxious arousal) provided the best fit to the data, although substantial support was demonstrated for theDSM-54-factor model. Low factor loadings were noted for two of the symptoms in theDSM-5model (psychogenic amnesia and reckless/self-destructive behavior), which raises questions regarding the adequacy of fit of these symptoms with other core features of the disorder. Overall, the findings from the present research suggest theDSM-5model of PTSD is a significant improvement over the previousDSM-IVmodel of PTSD.
