The Short-Form Health Survey (SF-12; Ware, Kosinski, & Keller, 1996) is a widely used screening device for measuring physical and mental health to assess quality of life. However, limited psychometric data exist for older adults, especially minority aging samples. Findings from Resnick and Nahm (2001) suggest revising traditional SF-12 scoring for use in older adults because of different factor loadings for two questions. This study sought to examine the reliability and validity of a verbally administered SF-12 in a community-dwelling sample of African Americans using the Detroit City-Wide Needs Assessment Database (N = 985). Reliability analysis resulted in an overall Cronbach's alpha of 0.77. Factor analysis with principal components extraction and varimax rotation yielded two factors. Consistent with Resnick and Nahm (2001), question 10 loaded on the physical health factor and question 12 on both the physical and the mental health factors. The overall SF-12 score was significantly related to use of home health services, visits to a physician, number of prescription drugs, as well as number of chronic diseases. The SF-12 appears to be a valid and reliable measure used as a screening device for use with African American elders overall. However, for optimal measurement, modifications to traditional scoring methods for the SF-12 should be considered.
简明健康调查问卷(SF - 12;Ware、Kosinski和Keller,1996年)是一种广泛用于测量身心健康以评估生活质量的筛查工具。然而,针对老年人,尤其是少数族裔老年样本的心理测量数据有限。Resnick和Nahm(2001年)的研究结果表明,由于两个问题的因子负荷不同,应修订传统的SF - 12评分以用于老年人。本研究旨在使用底特律全市需求评估数据库(N = 985),检验在非裔美国人社区居住样本中口头施测的SF - 12的信度和效度。信度分析得出总体Cronbach's alpha系数为0.77。采用主成分提取和方差最大化旋转的因子分析产生了两个因子。与Resnick和Nahm(2001年)一致,问题10加载在身体健康因子上,问题12加载在身体健康和心理健康因子上。SF - 12的总体得分与家庭健康服务的使用、看医生的次数、处方药数量以及慢性病数量显著相关。总体而言,SF - 12似乎是一种用于筛查非裔美国老年人的有效且可靠的测量工具。然而,为了实现最佳测量,应考虑对SF - 12的传统评分方法进行修改。
