目的:探讨灾后一年地震幸存者的创伤后应激反应的症状结构。方法:在汶川地震一年后通过723名极重灾区幸存者的PTSD症状自评量表(PCL)的评定数据对创伤后应激反应的5个理论模型进行了验证性因素分析。结果:包括闯入、回避、麻木和高警觉的四因素麻木模型具有最好的拟合度(χ2=715.823,CFI=0.982,RMSEA=0.086,AIC=795.823,BIC=979.159)。结论:5.12汶川地震一年后我国成人幸存者除了表现出典型的PTSD症状如闯入、回避和高警觉之外,还表现出麻木症状。
Objective: To explore the symptom structure of posttraumatic stress syndrome one year after of the earthquake disaster in China.Methods: Confirmatory factor analysis(CFA) was used to analyze the PCL scores of 723 survivors one year after of 5·12 Sichuan earthquake.Results: The four factor numbing model got the best fit index(χ2=715.823,CFI=0.982,RMSEA=0.086,AIC=795.823,BIC=979.159).Conclusion: This study showed that not only the classical PTSD symptoms,but also numbing exist in the survivors of 5·12 Sichuan earthquake.
