Posttraumatic stress disorder and posttraumatic growth among adult survivors of Wenchuan earthquake after 1 year: prevalence and correlates.

This study investigates the prevalence and predictors for posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) in adult survivors 1year after the 2008 Wenchuan earthquake. Questionnaires were used to collect the data. PTSD was assessed using the PTSD Check List-Civilian (PCL-C), and PTG was assessed using the Post Traumatic Growth Inventory (PTGI). A total of 2,300 individuals were involved in the survey with 2,080 completing the questionnaire, a response rate of 90.4%. The PTSD prevalence estimate in this study was found to be 40.1%, and the prevalence for PTG among the participants was measured at 51.1%. A bivariate correlation analysis indicated that there was a positive association between PTG and PTSD. In the conclusions, possible explanations for the findings and implications for future research are discussed.
