Symptoms of posttraumatic stress disorder among adult survivors two months after the Wenchuan earthquake.

This study investigated the symptoms of Posttraumatic Stress Disorder (PTSD) and associated risk factors among adult survivors 2 mo. after the Wenchuan earthquake in China. 228 survivors completed the Chinese version of the Impact of Event Scale-Revised. The prevalence of probable PTSD was 43%. The significant predictive factors for the severity of PTSD symptoms included being female, having lower educational level, being bereaved, and witnessing death. Findings of this study suggest that PTSD is a common mental health problem among earthquake survivors in China. Given inadequate knowledge and practices concerning the mental health of disaster victims in China, the information provided by this study is useful for directing, strengthening, and evaluating disaster-related mental health needs and interventions after earthquakes.
