DESCRIPTION (provided by applicant): Aims: Differences between racial and ethnic groups in subjective measures of health are well documented. However, subjective assessments also differ by confounding variables related to race/ethnicity as well as other potential sources of systematic bias, for example, language and/or culture. Hence, some of the most widely used subjective measures may not be valid across all sub-populations in the United States. This study examines measurement equivalence properties of the SF-36 (subjective measure) and a performance based measure (PBM) index of physical functioning ("gold standard") among several diverse racial/ethnic groups, addressing the following questions: 1) are there structural equivalence differences (measurement invariance) in the subjective measure and PBM across these populations; 2) are there indications of differential item functioning (DIP) within the subjective measure by racial/ethnic group; 3) does the subjective measure predict the performance-based measures equally across each group (metric and scalar equivalence), after controlling for other variables; and 4) do any observed differences vary according to gender? Methods: Approximately 330 subjects age 45-64 from each of the 4 racial/ethnic groups (non- Hispanic whites, non-Hispanic African-Americans, English-speaking Hispanics, Spanish-speaking Hispanics; N=1320) will be recruited from 4 general medicine clinics and other community centers in Cleveland and Chicago. The SF-36, a short demographic survey, and 11 physical tasks (upper and lower extremity strength, endurance, agility/dexterity, gait, and stair climbing) will be administered to each subject using trained clinical research assistants. Medical charts will be reviewed and chronic conditions and medications recorded. Data analysis using structural equation modeling, confirmatory factor analysis, multivariate regression techniques, and item response theory (IRT) will be used to investigate the above aims. Significance: This study will be the first to validate subjective measures of physical functioning and general health status using a performance-based "gold standard" including middle-age English and Spanish speaking Hispanics, adding to the knowledge of health status measurement of our fastest growing ethnic population. Regardless of outcome, results will provide heuristic value in directing further research, and will provide guidance in evaluating changes to current surveys.

描述（由申请人提供）： 目标：种族和族裔群体之间在主观健康指标方面的差异有据可查。然而，主观评估也因与种族/民族相关的混杂变量以及其他潜在的系统偏见来源（例如语言和/或文化）而有所不同。因此，一些最广泛使用的主观衡量标准可能不适用于美国的所有亚人群。本研究考察了几个不同种族/族裔群体中 SF-36（主观测量）和基于表现的身体机能测量（PBM）指数（“黄金标准”）的测量等效性，解决了以下问题：1）这些人群的主观测量和 PBM 是否存在结构等效性差异（测量不变性）； 2）在按种族/族裔群体进行的主观测量中是否存在差异项目功能（DIP）的迹象； 3）在控制其他变量后，主观测量是否在每个组中平等地预测基于绩效的测量（度量和标量等效）； 4）观察到的差异是否因性别而异？方法：将从克利夫兰和芝加哥的 4 个普通医学诊所和其他社区中心招募来自 4 个种族/族裔群体（非西班牙裔白人、非西班牙裔非裔美国人、说英语的西班牙裔人、说西班牙语的西班牙裔人；N=1320）的大约 330 名年龄在 45-64 岁之间的受试者。 SF-36、一项简短的人口统计调查和 11 项身体任务（上肢和下肢力量、耐力、敏捷性/灵巧性、步态和爬楼梯）将由经过培训的临床研究助理对每个受试者进行。将审查医疗图表并记录慢性病和药物。使用结构方程模型、验证性因素分析、多元回归技术和项目反应理论（IRT）的数据分析将用于研究上述目标。意义：这项研究将首次使用基于表现的“黄金标准”来验证身体机能和总体健康状况的主观测量，其中包括中年英语和西班牙语西班牙裔，增加了对我们增长最快的种族人口的健康状况测量的了解。无论结果如何，结果都将为指导进一步研究提供启发价值，并将为评估当前调查的变化提供指导。
