创伤后成长量表在汶川地震灾民中的修订与初步应用

目的:旨在5.12汶川地震灾民群体中修订创伤后成长量表,探索其因子结构,进行信效度分析。方法:研究1采用方便取样,在四川省国家级一般灾区的某个灾后安置点中,抽取了来自4个板房区的两组样本。样本群体包括工人、农民、商人和无业人员等。用创伤后成长量表施测。样本1(n=195)进行探索性因素分析,样本2(n=294)进行验证性因素分析。研究2在四川多所中学的学生中对所得创伤后成长量表进行效标效度检验(n=339)。结果:3因素(个人改变、人际改变和具体改变)模型在地震灾民群体中的拟合性(χ2=312.74,df=101,χ2/df=3.089,RMSEA=0.084,NN-FI=0.93,CFI=0.94,GFI=0.88,AGFI=0.84)优于5因素模型(χ2=667.8,df=178,χ2/df=3.752,RMSEA=0.097,NNFI=0.92,CFI=0.94,GFI=0.82,AGFI=0.77)。修订版创伤后成长量表的信度指标良好(α=0.87)。量表与抑郁、生活满意度指数、正性情绪有中等程度的显著相关,具有良好的效标效度。结论:创伤后成长量表在创伤相关群体中使用具有较好的信效度。

Revision and Preliminary Application of Posttraumatic Growth Inventory Among Earthquake Survivors in Sichuan

Objective: The present study aimed to revise Posttraumatic Growth Inventory(PTGI) in Chinese earthquake survivors in Sichuan,to explore the structure of PTGI and to test its reliability and validity.Methods: We adopted convenient sampling method to collect two samples in four temporary shelters in a severe disaster area,18 months after the 5.12 earthquake in study 1.The two samples contained manufactory staff,farmers,business persons,and the unemployed.Sample 1(n=195) was used for Exploratory Factor Analysis(EFA),whereas Sample 2(n=294) was used for Confirmatory Factor Analysis(CFA).Study 2 tested the validity of revised PIGI in high school students in Sichuan(n=339).Results: CFA indicated that a 3-factor solution(personal change,relationship development,and spiritual change fit the data better than the 5-factor model.The reliability and validity indexes were acceptable(α=0.87).PTGI was significantly correlated with the scores of positive affect,index of well being and depression as criterions.The construct and criterion validity of PTGI was acceptable.Conclusion: The Chinese version of Posttraumatic Growth Inventory is reliable and valid to conduct trauma-related research.
