Many researchers have developed various measures to evaluate the functional status of community-dwelling elderly. The Frenchay Activities Index (FAI) was developed to measure instrumental activities of daily living in stroke populations. The FAI has undergone the most intensive evaluation, but its factor structure has not been examined in Japan. The primary purpose of this study was to investigate the construct validity of the FAI for non-stroke community-dwelling elderly in Japan. The study subjects were 1,323 randomly selected community older residents in Hojo city, Ehime prefecture, the southern part of Japan. In order to investigate the construct validation, we performed factor analyses, i.e., exploratory factor analysis and confirmatory factor analysis. Furthermore, we examined the influences of age and gender on the FAI constructs. In the results, the FAI had a two-factor structure consisting of domestic chores, including washing clothes and preparing meals, and work and leisure, including gardening, driving and outings. Younger age was significantly related to increased performance on both factors. In addition, relative to females, males had a lower performance on the domestic chores and a greater performance on the work and leisure. These results suggest that the FAI satisfies the construct validity in the Japanese community-dwelling elderly. The FAI and its two factors provide important and clinically valuable information for understanding the patterns of functional status in the Japanese community-dwelling elderly.
许多研究人员已经开发出各种方法来评估社区老年人的功能状态。法国ay活动指数（FAI）是为测量中风人群的日常生活工具性活动而开发的。FAI经过了最深入的评估，但其因子结构在日本尚未得到检验。本研究的主要目的是调查FAI在日本非中风社区老年人中的结构效度。研究对象是从日本南部爱媛县北条市随机选取的1323名社区老年居民。为了调查结构效度，我们进行了因子分析，即探索性因子分析和验证性因子分析。此外，我们还研究了年龄和性别对FAI结构的影响。结果显示，FAI具有两因素结构，包括洗衣服和做饭等家务，以及园艺、开车和外出等工作与休闲活动。年龄较小与这两个因素的表现提高显著相关。此外，相对于女性，男性在家务方面的表现较低，而在工作与休闲方面的表现较高。这些结果表明，FAI在日本社区老年人中满足结构效度。FAI及其两个因素为了解日本社区老年人的功能状态模式提供了重要且具有临床价值的信息。
