主动反刍、创伤后应激障碍与创伤后成长的关系:一项来自汶川地震后青少年的长程追踪研究

本文以追踪研究的方式, 在汶川地震后3.5年、4.5年和5.5年三个时间点, 采用反刍问卷、创伤后应激障碍问卷和创伤后成长问卷对汶川地震后245名中学生进行调查。通过建立交叉滞后模型, 考察主动反刍、创伤后应激障碍与创伤后成长的相互作用关系。结果发现, 震后3.5~5.5年间, 创伤后应激障碍对主动反刍具有跨时间点的正向预测作用, 主动反刍对创伤后应激障碍跨时间点的预测作用不显著;主动反刍与创伤后成长之间存在跨时间点的相互正向预测关系;创伤后应激障碍与创伤后成长之间跨时间点的直接预测作用不显著, 但震后3.5年的创伤后应激障碍可以通过震后4.5年的主动反刍间接地正向预测震后5.5年的创伤后成长;创伤后应激障碍与创伤后成长的横断关系随着时间历程的变化而逐渐减弱。

The Relationship among Deliberate Rumination,Posttraumatic Stress Disorder and Posttraumatic Growth: Evidence From Longitudinal Study of Adolescents after Wenchuan Earthquake

The longitudinal study examined the course and bidirectional relation between deliberate rumination, posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). 245 secondary school students in the most severely affected area were investigated by self-report deliberate rumination, PTSD and PTG questionnaires at 3.5 year 4.5 year and 5.5 year after Wenchuan Earthquake. The cross-lagged structure equation analysis revealed that there are a one-way positively predictive relationship of PTSD onto deliberate rumination from 3.5 year to 5.5 year after earthquake. The bi-directional relationship between deliberate rumination and PTG was found, and PTSD have no directional relation to PTG from 3.5 year to 5.5 year after earthquake. Moreover, PTSD at 3.5 year have a indirectly positive effect on PTG at 5.5 year through deliberate rumination at 4.5 year after earthquake. In addition, the cross-sectional relationship between PTSD and PTG weaken with time change.
