本手稿检验了 CES-D 应用于老年非裔美国人 (n=227) 时的测量充分性。所有项目的响应分布都倾向于较少的症状，CES-D 的内部一致性是可以接受的（α = 0.86）。探索性因素分析揭示了抑郁症状的四个潜在因素：（1）抑郁/躯体； (2) 积极； （3）人际交往； (4)社会福祉。主要因素是抑郁症和躯体症状的结合，这是种族群体中常见的单维因素。此外，还出现了第四个之前未被识别的因素，被标记为“社会福祉”。这个因素包括三个可能影响老年人社交互动的项目：食欲、希望和谈话。这些发现为 CES-D 在不同人群中的独特测量特性提供了越来越多的证据。 (C) 2002 Elsevier Science Ireland Ltd. 保留所有权利。
This manuscript examines the measurement adequacy of the CES-D when applied in older African-Americans (n=227). The response distribution was skewed towards less symptomatology on all items, and the internal consistency of the CES-D was acceptable (alpha = 0.86). An exploratory factor analysis revealed four underlying factors of depressive symptomatology: (1) depressive/somatic; (2) positive; (3) interpersonal; and (4) social well-being. The primary factor was a combination of depression and somatic symptoms, a commonly reported uni-dimensional factor among ethnic groups. Additionally, a fourth factor emerged that has not previously been identified, labeled 'social well-being'. This factor consisted of three items that may tap into the social interactions of the elderly: appetite, hopeful, and talk. These findings contribute to the growing body of evidence on the unique measurement properties of the CES-D across diverse populations. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
