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）：目的：在主观措施中，种族和种族之间的差异已得到充分记录。但是，主观评估也通过混淆与种族/种族有关的变量以及其他潜在偏见的来源，例如语言和/或文化。因此，在美国所有亚种群中，一些最广泛使用的主观措施可能无效。这项研究研究了几个不同种族/族裔群体中SF-36（主观度量）（主观度量）和基于绩效的措施（PBM）指数（PBM）指数（PBM）指数（“黄金标准”）的测量当量特性（“金标准”），解决以下问题：1） 2）是否有迹象表明种族/族裔群体在主观衡量标准中的差异项目功能（DIP）； 3）在控制其他变量之后，主观度量是否可以预测每个组的基于绩效的度量（度量和标量等效）； 4）观察到的差异是否根据性别有所不同吗？方法：来自4个种族/民族群体中每个人（非西班牙裔白人，非西班牙裔非裔美国人，讲英语的西班牙裔西班牙裔，讲西班牙语的西班牙裔美国人； n = 1320），大约有330名45-64岁的受试者。 SF-36，简短的人群调查以及11项身体任务（上肢和下肢强度，耐力，敏捷性/敏捷性，步态和爬楼梯）将使用训练有素的临床研究助理对每个受试者进行管理。将审查医疗图表，并记录慢性病和药物。使用结构方程建模，验证性因素分析，多元回归技术和项目响应理论（IRT）的数据分析将用于研究上述目的。意义：这项研究将是第一个使用基于绩效的“黄金标准”（包括中年英语和西班牙语的西班牙裔人）来验证身体机能和一般健康状况的主观措施的研究，这增加了我们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，结果都将在指导进一步的研究时提供启发式价值，并为评估当前调查的变化提供指导。
