创伤后成长量表在汶川地震灾民中的修订与初步应用

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

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。

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.
