简明抑郁-幸福感量表中文版测评成年人的效度和信度

Validity and reliability of the Chinese version of the Short Depression-Happiness Scale in Chinese adults

目的:检验简明抑郁-幸福感量表中文版(SDHS-C)在我国成年人中的效度和信度。方法:样本1共3060人,进行条目分析和探索性因子分析(EFA);样本2共1432人,进行验证性因子分析(CFA)和效标效度分析。用生命意义感问卷的拥有意义分量表(MLQ-p)、简明焦虑量表(SSAI)、阿森斯失眠量表(AIS)作为检验效标效度的工具。结果:EFA得到抑郁感和幸福感2个因子,累计方差解释率70.8%;CFA结果表明两因子模型的拟合指数(χ2/df=7.18,CFI=0.98,TLI=0.96,RMSEA=0.07)优于单因子模型(χ2/df=40.54,CFI=0.85,TLI=0.75,RMSEA=0.17);SDHS-C总分与MLQ-p得分负相关(r=-0.42),与SSAI、AIS得分正相关(r=0.69、0.44),均P<0.001。总量表的Cronbachα系数为0.82。SDHS-C总分的性别和年龄段差异均有统计学意义(均P<0.001)。结论:简明抑郁-幸福感量表中文版在我国成年人群体中具有较好的效度和信度。

Objective:To test the validity and reliability of the Chinese version of the Short Depression-Happiness Scale(SDHS-C) in Chinese adults.Methods:Totally 3060 people were subjected for item analysis and exploratory factor analysis(EFA).A total of 1432 people were included in sample 2 for confirmatory factor analysis(CFA) and criterion validity analysis.The presence of meaning sub-scale of Meaning in Life Questionnaire(MLQ-p),Short State Anxiety Inventory(SSAI) and Athens-Insomnia Scale(AIS) were used to test the validity of the criterion.Results:EFA found 2 factors named depression and happiness which explained 70.8% of the total variance.CFA results showed that the two-factor model(χ^2/df=7.18,CFI=0.98,TLI=0.96,RMSEA=0.07) was better than the one-factor model(χ^2/df=40.54,CFI=0.85,TLI=0.75,RMSEA=0.17).The SDHS-C scores were negatively correlated with scores of MLQ-p(r=-0.42,P<0.001),and positively correlated with scores of SSAI and AIS(r=0.69,0.44,Ps<0.001).The revised scale had a good reliability,with Cronbach α of 0.82.The gender and age difference of SDHS-C total score was significant(Ps<0.001).Conclusion:The Chinese version of the Short Depression-Happiness Scale has good validity and reliability in Chinese adults.
