地震对灾民创伤后应激障碍的长期影响

创伤后应激障碍是震后最常见的心理创伤。以往研究多关注灾民在震后短时间内的应激反应, 地震两年后创伤心理研究非常缺乏。本研究拟结合汶川地震后进行的6次重复测量数据(2008~2016)重点探讨：创伤后应激障碍在震后不同时点的变化轨迹及影响因素; 震后针对创伤后应激障碍在不同时点的干预内容。预期研究成果不仅是对灾后心理创伤长期影响研究的补充, 也将为灾后救助政策以及心理干预提供依据。

Long impact of earthquake on Post-traumatic Stress Disorder

Post-traumatic stress disorder (PTSD) is common among earthquake survivors, and will adversely affect individuals, families and societies. Recent systematic review study showed that the number of health related academic articles dropped dramatically 2 years after the earthquake, which, to some extent, reflected, that researchers ignored the long term impact of a disaster to the affected population. Clearly, then, there is a need for more research on the long-term health consequences of earthquake. This study is a follow-up study conducted among survivors of the Sichuan earthquake, based on six-wave repeated cross-sectional survey during 2008 to 2016. Following questions will be answered: what is the prevalence of probable PTSD at different time points following an earthquake? Why people have different symptoms: Chronic, delayed, recovered, and resilience? How is the relationship between PTSD and changes of income, relationship and resources? When and how to organize and promote activities for PTSD intervention? The results of this study have theoretical significance and may be helpful for further mental health interventions for survivors after earthquakes. It will provide references for policymakers to make policy for public health service in disaster.
