目的 验证抑郁-焦虑-压力量表精简版(DASS-21)在震后学生群体中的信效度.方法 使用DASS-21精简版和加州大学创伤后应激障碍反应指数修改版(UCLA PTSD RI)对雅安地震灾区876名五至九年级学生心理健康状况进行测查.结果 (1)各条目间具有较好的区分度,CR值为9.268~22.438 (P<0.01),与各维度相关系数为0.306~ 0.742;(2) DASS-21有较高的内部一致性信度(总量表及三个分量表的α系数为0.781~0.911);(3)量表总分与抑郁、焦虑、压力间的相关系数为0.774~0.914,PTSD与量表总分、抑郁、焦虑、压力分量表间相关系数为0.626~ 0.774;(4)对量表进行探索性因素分析表明,KMO值为0.937、X2=3126.85、df=210、P<0.01,抽取3个因子可解释方差总变异的47.813%;各条目因子载荷为0.339~0.715;对量表三因素结构进行验证性因素分析,数据拟合指标X2/df=4.180(P<0.01),PCFI=0.728,CFI=0.904、IFI=0.905、TLI=0.881、RMSEA=0.060.结论 DASS-21精简版在震后学生群体中具有良好的适用性,可作为该群体应激评估的有效工具.

Other Abstract

Objective To test the reliability and validity of the short version of depression-anxiety-stress scale (DASS-21) for students in the disaster region.Methods DASS-21 and the Chinese version of UCLA PTSD Reaction Index for DSM-IV,Revision I were used to evaluate psychological health among 876 students from grades 5 to 9 after Ya' an earthquake.Results (1) Each of the items had a good distinction degree,with CR value ranging from 9.268 to 22.438 (P< 0.01),and the correlation coefficients ranged from 0.306 to 0.742.(2)The Cronbach' s alpha coefficients ranged from 0.781 to 0.911.(3) The correlation coefficients between total score and each dimension ranged from 0.714 to 0.914,and the correlation coefficient between PTSD and total DASS score,depression anxiety and stress score was 0.626-0.774.(4)Through the item analysis and explore factor analysis,the revised scale contained 21 items and 3 subscales which could explain 47.813% of the total variance(KMO =0.937,x2 =3126.85,df=210,P<0.01),and the results of confirmatory factor analysis supported the three-factor model (x2/df=4.180,P<0.01,PCFI =0.728,CFI =0.904,IFI =0.905,TLI =0.881,and RMSEA =0.060),and the load of each item was between 0.339 to 0.715.Conclusion The short version of DASS-21 is reliable and valid,and can be used as a tool for post-disaster stress assessment on local students.
