摘要
目的:在军校学员群体中初步修订创伤后成长量表,进行条目分析、探索并验证其因子结构。方法:将创伤后成长量表翻译成中文,施测于706名近几年经历各种创伤事件的军校学员。将样本按事件奇偶分半,样本1(n=353)用于探索性因素分析,样本2(n=353)用于验证性因素分析和信度检验。结果:①探索性因素分析抽取4个特征值大于1的因子(个人力量的改变、对生活的理解和欣赏、人际关系的改变、新的可能性),能解释总方差的56.37%。②验证性因素分析4因子模型,χ2/df=3.054,NNFI=0.88,CFI=0.90,GFI=0.89,IFI=0.90,RMSEA=0.076。③4因子结构的量表内部一致性信度α=0.902。结论:修订后的4因子结构量表信、效度检验基本达到心理测量学要求,可用于大学生群体创伤后成长的评估。
Objective： To revise Posttraumatic Growth Inventory （PTGI） among Chinese military undergraduates, and to examine the factor structure of PTGI. Methods： PTGI was first translated into Chinese, and then was administrated to 706 military undergraduates who had experienced a significant negative life event during the past several years. Two subsam- pies were split by odd and even： one（n=353） was examined with the Exploratory Factor Analysis（EFA）, and the other（n= 353） was examined with Confirmatory Factor Analysis （CFA）. Results： （~）EFA produced four factors with eigenvalues greater than one, accounting for 56.37% of the common variance. The factors were labeled change of persona/strength, appreciation of life, change of relation to others, new possibilities. @）CFA indicated the 4 factor model（x2/df=-3.054, NNFI= 0.88 ,CFI--0.90,GFI=0.89 ,IFI=0.90, RMSEA=0.076） was superior to the original 5 factor model of PTGI. （3）The internal consistency of the 4 factor model of PTGI was α=0.902. Conclusion： The validity and reliability of the revised version of PTGI is acceptable, It is applicable to trauma-related research.
