中文版自我分化量表在青少年群体中的信效度研究

Verifying the reliability and validity of revised Chinese Differentiation of Self Inventory in adolescents

目的:以青少年群体为样本检验自我分化量表修订版(DSI-R)的信度和效度。方法:在芜湖市部分初中、高中和大学抽取1500名学生用DSI-R进行测试,完成项目分析、探索性因子分析、内部一致性信度检验和效标关联效度分析。结果:修订后的DSI-R具有较好的项目区分度,各条目与总分相关系数为0.331~0.650(P均<0.001),CR值为3.282~25.517(P均<0.01);探索性因子分析提取了5个公因子,方差累计贡献率为50.589%;问卷α系数、分半信度分别是0.583~0.893、0.580~0.844。结论:修订后的中文版自我分化量表的分半信度、结构效度、效标关联效度均较理想,符合心理测量学的要求。

Objective:To verify the reliability and validity of differentiation of self inventory-revised version(DSI-R)in adolescents.Methods:DSI-R was used to survey 1500 students from middle and high schools as well as colleges in Wuhu area,and verified through analysis of the items in DSI-R,exploratory factors,internal consistency estimation,and validation of the reliability and criterion.Results:The findings indicated better differentiation among items defined in the revised Chinese version of DSI,with correlation coefficients ranging from 0.331 to 0.650(all P<0.001),and critical value(CR)from 3.282 to 25.517(all P<0.01).Exploratory factor analysis determined by the 5 dimensions showed 50.59%by accumulated variance contribution rate.The Cronbach′sαcoefficient and split-half reliability were 0.583-0.893 and 0.580-0.844,respectively.Conclusion:Revised Chinese version of DSI has better split-half reliability,structural validity and validity associated with criteria,and can meet with psychometric standard.
