目得：为了比较不同人种/种族亚群的健康相关生活质量（HRQOL）研究结果，重要的是要证明因子不变性，即，这些项目在所研究的种族/民族群体中具有等同意义。本研究采用23项PedsQL（TM）4.0通用核心量表（Generic Core Scales.METHODS）对5-18岁儿童自报的HRQOL在不同种族/民族组间的因变量进行了检验：进行了多组验证性因素分析（CFA），指定了4个种族/民族组间的5因素模型（白色非西班牙裔，西班牙裔，亚洲/太平洋岛民，黑人非西班牙裔）。提出了多组结构方程模型，以比较四个种族/民族亚群的因素结构。该分析基于从诊所、学校和社区人群中招募的5，490名儿童。基于模型之间的比较拟合指数（CFI）的稳定性以及实际拟合的几个附加指数（包括近似均方根误差（RMSEA）、非范数拟合指数（NNFI）、和吝啬规范拟合指数（PNFI）。结论：研究结果支持一个等效的五因素结构，在四个种族/民族亚群研究。基于这些数据，可以得出结论，四个种族/民族组的儿童以相似的方式研究解释项目，无论其种族/民族如何。Ann Epidemiol 2009;19：575-581.

PURPOSE: In order to compare health-related quality of life (HRQOL) research findings across race/ethnicity subpopulations, it is important to demonstrate factorial invariance, i.e., that the items have equivalent meaning across the race/ethnicity groups studied. This study examined the factorial invariance of child self-reported HRQOL across race/ethnicity groups for ages 5-18 years utilizing the 23-item PedsQL (TM) 4.0 Generic Core Scales.METHODS: Multigroup confirmatory factor analysis (CFA) was performed, specifying a five-factor model across four race/ethnicity groups (White Non-Hispanic, Hispanic, Asian/Pacific Islander, Black Non-Hispanic). Multigroup structural equation models were proposed in order to compare the factor structure across the four race/ethnicity subpopulations. The analyses were based on 5,490 children recruited from clinic, school, and community populations.RESULTS: Strict factorial invariance across the four race/ethnicity groups was demonstrated based on stability of the Comparative Fit Index (CFI) between the models, and several additional indices of practical fit including the Root Mean Squared Error of Approximation (RMSEA), the Non-Normed Fit Index (NNFI), and the Parsimony Normed Fit Index (PNFI).CONCLUSIONS: The findings support an equivalent five-factor structure across the four race/ethnicity subpopulations studied. Based on these data, it can be concluded that children across the four race/ethnicity groups studied interpreted items in a similar manner regardless of their race/ethnicity.
