Suicidality associated with PTSD, depression, and disaster recovery status among adult survivors 8 years after the 2008 Wenchuan earthquake in China

It has been eight years since the Wenchuan earthquake. We don't know how the lives of those affected by the disaster may remain blighted by its effects, or how many remain thus affected. The aim of the present study was to examine the relationship of disaster exposure, PTSD, depression and suicidal behaviors, using data from a cross-sectional survey conducted in earthquake-affected areas of China. 1369 participants were recruited from two different sites that were severely affected by the Wenchuan earthquake. The survey assessed suicidality (suicidal ideation, plans and attempts) and other mental health issues. Probable PTSD was assessed using the Impact of Event Scale-Revised (IES-R). The Center for Epidemiologic Studies Depression Scale (CES-D) Chinese edition was used to assess depressive symptoms. The results showed that 11.2% of participants felt that their lives had not yet recovered from the effects of the Wenchuan earthquake, even after eight years. Suicidal ideation, plans, and attempts were reported by 9.1%, 2.9%, and 3.3%, respectively, of the respondents. PTSD, depression, and perceived non -recovery were highly associated with suicidality. These results indicate that suicidality can be a long-term mental health sequela of disaster. Targeted, long-term suicide prevention programs for adult survivors should be further developed.
