Post-traumatic stress disorder and its risk factors in bereaved Tibetan adolescents 3 years after the 2010 Yushu earthquake, a cross-sectional study in China.

ABSTRACT

OBJECTIVES: This study examined the incidence of symptomatological post-traumatic stress disorder (PTSD) in bereaved Tibetan adolescents 3 years after the 2010 Yushu earthquake, then to identify possible and relational risk factors of PTSD by a cross-sectional study. METHODS: A total of 867 bereaved Tibetan adolescents seriously impacted by the 2010 earthquake were investigated. Symptomatological PTSD was evaluated by the PTSD Checklist-Civilian Version. And coping styles were evaluated by the Coping Styles Scale. Exposure of trauma to the 2010 Yushu earthquake was evaluated by a checklist about earthquake containing sociodemographic variables. RESULTS: 3 years after the Yushu earthquake, 24.4% of the bereaved Tibetan adolescents had symptomatological PTSD. The results also indicated that coping styles and disaster-related experiences after the 2010 earthquake were connected with PTSD among survivors. When the 2010 earthquake struck, those having symptomatological PTSD were more probably to be buried/injured/amputated, and to witness burial/injury/death, and to have property damage. An individual who adopted positive coping skill was probably to have less symptomatological PTSD. CONCLUSIONS: The results showed that the existence of PTSD in bereaved Tibetan adolescents in the Yushu earthquake was very prevailing after 3 years. Effective psychological rescue work should be carried out, especially targeting bereaved Tibetan adolescents with more severe PTSD.
