To compare the reliabilities and convergent validities of five CES-D (Center for Epidemiologic Studies Depression) composite scores in two ethnic/racial groups of community-dwelling older adults.
CES-D measurement equivalence was tested with Structural Equation Modeling in Puerto-Rican (PR) and African American (AA) older adults, then reliabilities of five composite scores and their convergent validities were compared.
Bayesian CES-D scores had the highest reliabilities, followed by software estimated factor scores, the unit weight, and the weighted scores. Bayesian CES-D scores, factor scores, and surprisingly a group-specific three-item brief CES-D score exhibited better convergent validity than the unit-weight and weighted CES-D scores.
An ethnic group-specific three-item brief CES-D score emerged as a reliable CES-D measure in PR and AA older adults. We conclude that practitioners could emphasize three main symptoms in individual older adults in screening for depression, and researchers can model with confidence the relationships between the CES-D brief scale and its correlates.
比较五种 CES-D(流行病学研究中心抑郁量表)综合评分在两个不同族裔/种族的社区老年人中的可靠性和收敛效度。
采用结构方程模型对波多黎各裔(PR)和非裔美国人(AA)老年人进行 CES-D 测量等效性检验,然后比较五种综合评分的可靠性及其收敛效度。
贝叶斯 CES-D 评分的可靠性最高,其次是软件估计的因子评分、单位权重和加权评分。贝叶斯 CES-D 评分、因子评分,甚至令人惊讶的是,特定于群体的三个项目简短 CES-D 评分比单位权重和加权 CES-D 评分具有更好的收敛效度。
一个特定于族裔群体的三个项目简短 CES-D 评分成为 PR 和 AA 老年人中可靠的 CES-D 测量方法。我们的结论是,从业者可以在筛查抑郁症时强调个体老年人的三个主要症状,研究人员可以有信心地对 CES-D 简短量表及其相关因素之间的关系进行建模。
