【摘要】 目的:在经历汶川地震的初中生群体中修订创伤后成长量表(Post-traumatic Growth Inventory,PTGI),并考察其信效度。方法:采用方便取样,在重庆市2个一般灾区的2所初中共抽取2个样本,用创伤后成长量表、儿童抑郁量表(Children’s Depression Inventory,CDI)、儿童版事件影响量表(Children’s Revised Impact of Event Scale,CRIES)进行施测。用样本1(N=294)进行探索性因素分析,样本2(N=625)进行验证性因素分析。结果:(1)探索性因素分析获得3因素模型(人际关系、新可能性、个人力量),各条目在所属因子的载荷为0.41～0.77,3因子可解释总变异为47.2%。验证性因素分析发现拟合指标较好,IFI=0.990,CFI=0.990,RMSEA=0.051,χ2/df=3.082。将3因素模型和原5因素模型比较,发现前者指标优于后者(5因素:IFI=0.987,CFI=0.981,RMSEA=0.053,χ2/df=3.317)。(2)创伤后成长量表修订版内部一致性信度在0.663～0.851之间。(3)PTGI总分及各分量表分与CRIES侵袭量表得分呈正相关(r=0.19～0.27,P<0.01),与抑郁量表得分呈负相关(r=-0.21～-0.29,P<0.01)。结论:创伤后成长量表修订版具有较好的信、效度,可用于同龄人群创伤后成长研究。更多还原

【Abstract】 Objective:To revise the Post-traumatic Growth Inventory(PTGI) in a sample of adolescents who experienced the Wenchuan earthquake.Method:The Chinese version of PTGI together with the Children’ s Depression Inventory(CDI)and Children’ s Revised Impact of Event Scale(CRIES)were administrated among 2 samples of the middle school students from two middle schools in Chongqing city.Result:A three-factor model of PTGI(interpersonal relationship,new possibility,and personal strength)was found in the first sample by exploratory factor analysis and was confirmed in the second sample by confirmatory analysis.The main parameters were as follows:IFI=0.990,CFI=0.990,RMSEA=0.051,and χ2/df=3.082.The original five-factor model(IFI=0.987,CFI =0.981,RMSEA=0.053,and χ2/df =3.317)was also tested by confirmatory analysis and was found inferior to the three-factor model.The reliability of the revised scale was acceptable,with Cronbach’ s a coefficients ranging from 0.66~0.85.The total score of PTGI and the score of sub-scales were moderately correlated with the intrusion scale in CRIES,with coefficients ranging from 0.19 to 0.27.The total score of PTGI and the score of sub-scales were negatively correlated with CDI,with coefficients ranging from -0.21 to -0.29.Conclusion:The newly revised adolescent version of PTGI demonstrates good structure validity and acceptable reliability.It may be a potentially good instrument to measure posttraumatic growth among Chinese adolescents.更多还原
