Abstract
The current study investigated the latent structure of PTSD symptoms with a sample of 326 Chinese survivors who lost their children during a deadly earthquake. The results of confirmatory factor analysis indicated that a five-factor intercorrelated model comprised of intrusion, avoidance, emotional numbing, dysphoric arousal, and anxiety arousal provided significant better fit than both the four-factor numbing model of King, Leskin, King, and Weathers (1998) and the four-factor dysphoria model of Simms, Watson, and Doebbeling (2002). Further analyses with structural equation modeling showed that the PTSD factors were differentially associated with external measures of psychosocial and physical health-related quality of life. The findings provide further empirical support for the novel five-factor PTSD model, and carry implications for conceptualizing and assessing PTSD for the upcoming DSM-5.
