title: Posttraumatic stress disorder and posttraumatic growth coexistence and the risk factors in Wenchuan earthquake survivors.
abstract: Various studies have assessed the negative and/or positive changes in the aftermath of traumatic events. Yet few of these have addressed the factors associated with the coexistence of both negative and positive changes after a devastating earthquake. The aim of this study is to assess the relationship between the negative and positive changes and elucidate the risk factors of such changes one year after Wenchuan earthquake. A total of 2080 survivors from 19 counties participated in a self-report questionnaire survey which included the posttraumatic stress disorder (PTSD) Check list-Civilian, the posttraumatic growth PTG Inventory (PTGI). The prevalence of PTSD and moderate PTG was found to be 40.1% (95% CI [37.9% 42.3%]) and 51.1% (95% CI [48.9% 53.3%]). The PTSD and moderate PTG coexistence was 19.6% (95% CI [17.8% 21.4%]). PTSD symptom severity was significantly positively associated with the PTG score. Middle aged groups (31-40 and 41-50 years old, OR=2.323, 95% CI [1.059, 5.095] and OR=2.410, 95% CI [1.090, 5.329] respectively), those with lower income levels (OR=8.019, 95% CI [2.421, 26.558]), those living in temporary house (OR=1.946, 95% CI [1.280, 2.956]), and those who had had less social support (OR=1.109, 95% CI [1.076, 1.143]) had a significantly higher possibility for the presence of PTSD and moderate PTG coexistence. The results indicated the widespread positive changes in earthquake survivors. Better income levels and living conditions and higher social support were suggested to promote PTG in those with PTSD.
