Research on outcome evaluation of the support given to families of an aged person who requires care

本研究旨在编制家庭生活方式稳定量表，以评估日本照顾年老家庭成员的家庭所得到的支持。首先，通过质的研究揭示了家庭生活方式稳定性的结构。其次，根据研究结果，提取了58个用于测量家庭生活方式稳定性的条目。随后，我们对233个在家中照顾体弱老人的日本城市家庭进行了调查。用因子分析确定量表的因子结构，用克朗巴赫α系数进行信度分析。本研究以32个项目构建了护理掌握、家庭纽带、家庭参与照料、家庭生活回旋余地和居家照料服务管理5个因素，并提取了5个因素作为家庭生活方式稳定性的规则因素。因子提取后，累积贡献率为48.9%。每个因素的克朗巴赫α系数在0.697到0.795之间，总系数为0.880。验证了该量表的内容效度和内部一致性。然而，有必要对效度的其他各个方面进行研究，如同时效度和预测效度。此外，有必要制定一个修订版的FLSS，其中将包括较少的老年人受访者的项目。

The purpose of this study was to develop the Family Lifestyle Stability Scale (FLSS) for evaluating the support given to the families caring for frail elderly household members in Japan. First, we revealed the structure of family lifestyle stability in this regard by the qualitative research. Second, based on the results, 58 items were extracted for use in measuring family lifestyle stability. Following this, we conducted a survey of 233 urban Japanese families caring, for frail elderly people at home. The factor structure of the FLSS was determined using factor analysis, and the reliability was analyzed using the Cronbach α coefficient. As a result, five factors, namely, mastery of care, family bonds, family participation in caregiving, leeway in family's life, and management of the home care service were constructed using 32 items and were extracted as rule factors of family lifestyle stability. After the factor extraction, the accumulation contribution was 48.9%. The Cronbach α coefficients for each factor ranged from 0.697 to 0.795, and the overall coefficient was 0.880. The content validity and internal consistency of the FLSS was confirmed. Nevertheless, it is essential to study various other aspects of validity, such as concurrent validity and predictive validity. Moreover, it is necessary to develop a revised version of the FLSS, which will include fewer items for elderly respondents.
