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 1 year 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.
