The purpose of this study was to examine the factorial invariance of the Abbreviated Neighborhood Environment Walkability Scale (NEWS-A) across subgroups based on demographic, health-related, behavioral, and environmental characteristics among Nurses' Health Study participants ( = 2,919; age = 73.0, = 6.9 years) living in California, Massachusetts, and Pennsylvania. A series of multi-group confirmatory factor analyses were conducted to evaluate increasingly restrictive hypotheses of factorial invariance. Factorial invariance was supported across age, walking limitations, and neighborhood walking. Only partial scalar invariance was supported across state residence and neighborhood population density. This evidence provides support for using the NEWS-A with older women of different ages, who have different degrees of walking limitations, and who engage in different amounts of neighborhood walking. Partial scalar invariance suggests that researchers should be cautious when using the NEWS-A to compare older adults living in different states and neighborhoods with different levels of population density.
本研究旨在检验简化邻里环境步行适宜性量表（NEWS-A）在按人口统计学、健康相关、行为和环境特征划分的亚组间的因子不变性，这些亚组来自居住在加利福尼亚州、马萨诸塞州和宾夕法尼亚州的护士健康研究参与者（n = 2919；年龄 = 73.0岁，标准差 = 6.9岁）。进行了一系列多组验证性因子分析，以评估因子不变性的越来越严格的假设。在年龄、步行限制和邻里步行方面，因子不变性得到了支持。在州居住和邻里人口密度方面，仅支持部分标量不变性。这一证据支持对不同年龄、有不同程度步行限制且在邻里步行量不同的老年女性使用NEWS-A。部分标量不变性表明，研究人员在使用NEWS-A比较居住在不同州和人口密度不同的邻里的老年人时应谨慎。
