张北尚义地震后创伤后应激障碍随访研究

纵向研究地震后创伤后应激障碍（ＰＴＳＤ）的发病率及其特点。方法：研究对象随机选自距震中不同距离的两个村，分别有１８１人和１５７人在震后３个月、９个月时接受调查，并以ＳＤＭ－ＩＶ对ＰＴＳＤ进行诊断，同时测查了ＷＨ０－ＱＱＬ和ＳＣＬ－９０的三个分量表。结果：初始暴露程度较高而受灾后支持较好的群体ＰＴＳＤ发病率低，震后９月，两村ＰＴＳＤ发病率分别为１９．８％和３０．３％，就总体而言，震后９月ＰＴＳＤ发病

Longitudinal Study of Earthquake-related PTSD in North China

Objective: Longitudinally describe the rates of posttraumatic stress disorder (PTSD) in two groups with different exposure to an earthquake attacking North China. Method: The subjects were sampled randomly from two villages at different distances from epicenter. 181 and 157 subjects were assessed at 3 months and 9 months after the earthquake, respectively for PTSD with the DSM-IV criteria. WHO QOL-BREF and three subscales of Symptoms Checklist were also administered at both assessment points. Results: The higher initial exposure coupled with increased support resulted in lower PTSD than lower exposure with less support. DSM-IV PTSD onset rates within 9 months for the two groups were 19.8% and 30.3% respectively. As a whole, the earthquake related PTSD onset rate within 9 months was 24.2%. Conclusion: PTSD in disaster victims in China might be as prevalent and persistent as those found elsewhere. Prompt and effective post-disaster intervention could mitigate the impacts of initial exposure and reduce the probability of PTSD occurrence.
