中文摘要：

目的：探讨社会性创伤是否可能通过降低心理控制感的方式加剧创伤后应激障碍（PTSD）的发展。方法：通过方便取样抽取正常组被试390人（样本一）、临床组被试86人（样本二）,运用自编社会性创伤问卷、夏皮罗一般控制感子量表、DSM-5创伤后应激障碍检测量表进行施测。临床组被试还完成了创伤历史筛查问卷。结果：（1）社会性创伤-心理控制感-PTSD中介效应模型拟合度高;（2）正常组,心理控制感在社会性创伤和PTSD之间的间接效应显著,起到部分中介作用。（3）临床组,在对传统创伤的影响进行控制的条件下,心理控制感的间接效应仍显著,起到部分中介作用。结论：社会性创伤可以通过心理控制感间接预测创伤后症状的严重性,对心理控制感的干预具有重要的临床价值。

英文摘要：

Objective： The current study investigated whether perceived control played a mediating role on the relation- ship between social trauma and posttraumatic stress disorder（PTSD）. Methods： 390 normal participants（Sample 1） and 86 clinical participants（Sample 2） were recruited by convenient sampling in the study to complete the Social Trauma Question- naire（self- made）, the General Domain Sense of Control Scale（in Shapiro Control Inventory）, and the PTSD Checklist for DSM-5. Clinical sample also completed the Trauma History Screen. Results： ①The mediating effect model of social trau- ma-psychological control-PTSD showed good global fit. ②In normal group, psychological control was found to partially mediate the association between social trauma and PTSD. ③The partially mediating effect of psychological control was also significant while the effect of the traditional trauma was controlled. Conclusion： The results suggest psychological control is one of the important mediators between social trauma and posttraumatic stress responses. It is clinically important to perform an intervention on perceived control.
