To determine the usefulness of the Center for Epidemiological Studies Depression Scale (CES-D) as a measure of depressive symptoms among frail and disabled elderly, we conducted a first- and second-order confirmatory factor analysis testing the four-factor structure of the CES-D and the existence of a single underlying second-order factor. We also examined the relative contribution of the somatic factor of the total symptom score, and relationships of age, race, functional status, and health with the four factors. We found that the factor structure is replicated when used with frail elderly, and scores are not distorted by the disproportionate influence of somatic items. Age and health do not affect the somatic subscale more than the other three subscales. Functional limitations are associated with higher somatic scores. We conclude that the CES-D is an appropriate tool to measure depressive symptoms in frail elderly.
为了确定流行病学研究中心抑郁量表（CES-D）作为衡量体弱和残疾老年人抑郁症状的工具是否有用，我们进行了一阶和二阶验证性因子分析，以检验CES-D的四因子结构以及单一潜在二阶因子的存在。我们还研究了躯体因子对总症状评分的相对贡献，以及年龄、种族、功能状态和健康状况与这四个因子的关系。我们发现，该量表用于体弱老年人时，其因子结构可以重现，且躯体项目的不成比例影响不会扭曲得分。年龄和健康状况对躯体子量表的影响并不比其他三个子量表更大。功能受限与更高的躯体得分相关。我们得出结论，CES-D是测量体弱老年人抑郁症状的合适工具。
