摘要
目的:分析10项CES-D问卷在中老年人群中的信效度,以及该量表在中年和老年群体中的信效度差异。方法:使用中国健康与养老追踪调查2011年数据,样本人群年龄45岁以上,共14931人;首先,运用区分度分析量表各条目对不同水平被试的区分能力;其次,分别对整个人群、老年人群和中年人群进行内部一致性检验,并在3个不同因子结构的假定下(单因子结构;二因子结构:积极因子和消极因子;三因子结构:积极因子、消极因子和躯体因子)分别对3个人群进行验证性因子分析,并利用多组验证性因子分析检验两因子结构模型在中年人群和老年人群中的恒等性。结果:区分度分析发现,在总分百分位数27%的最高组和最低组之间各项目得分具有显著的差异,在整个人群中的科隆巴赫系数为0.815,两因子结构对整个样本人群拟合较好;在中年人群和老年人群中,内部一致性系数分别为0.814、0.813;两因子结构模型在4个嵌套模型的对比检验中显示,△CFI、△RMSEA和△SRMR的差异均满足横等性最低临界值要求。结论:10项CES-D量表具有较高的信效度,两因子结构模型在中年人群和老年人群具有恒等性,量表具有良好的区分效度,能有效地测量中老年人群的抑郁水平。
Objective：To examine the reliability and validity of 10-item of Center for Epidemiologic Studies Depression Scale among older adults and test the scale invariance for middle aged and older a-dults.Methods：Data were derived from 2011 wave of China Health and Retirement Longitudinal Study and 14931 individuals with 45 or more years old.First,item discrimination analysis was used to test the discriminative ability among different people with various level;Second,among the entire sample,older a-dults and middle aged adults,internal consistency analysis was conducted to test the internal consistency, and,Confirmatory Factor Analysis（ CFA） were used to test the three assumed factors：A one-factor mod-el,a two-factor model（Depressed affect,Positive affect）and a three-factor（Depressed affect,Somatic affect Positive affect）respectively.Next,multiple-group analysis was conducted to test the scale invari-ance for middle aged and older adults.Results：The discrimination analysis showed that item score differ-ences between the highest and lowest 27%percentile in total scores was statistically significant.The Cron-bach＇s alpha was 0.815,0.814 and 0.813 for entire sample,middle aged adults and older adults respec-tively and data support the two-factor model for the entire sample;For comparison with the two-factor unrestrictive model,the△CFI,△RMSEA and △SRMR meet the cutoff point for scale invariance.Con-clusion：10-item CESD demonstrates adequate reliability and validity,two-factor model has factorial e-quivalence across the older and middle aged adults,the scale has good discrimination and can be used to screen depressive symptoms among middle aged and older adults.
