To assess the predictive validity of the 15 components of the Tilburg Frailty Indicator (TFI), a self-report questionnaire, for quality of life domains physical health, psychological, social relations and environmental in community-dwelling older persons in a longitudinal study.
The predictive validity of the components of the TFI was tested in a sample of 484 community-dwelling persons aged 75 years and older in the Netherlands in 2008 (response rate 42%). A subset of all respondents participated two years later, in 2010 (n = 261, 54%), and a subset of these respondents participated again in 2012 (n = 196, 75%). The WHOQOL-BREF was used for measuring four quality of life domains.
Four physical frailty components (physical unhealthy, difficulty in maintaining balance, difficulty in walking and physical tiredness), one psychological frailty component (feeling down) and one social frailty component (lack of social support) predicted future scores on quality of life domains, even after controlling for background characteristics and diseases.
This longitudinal study showed that quality of life is predicted by physical as well as psychological and social frailty components. This finding emphasizes the relevance of a multidimensional assessment of frailty. To improve quality of life of older persons, special attention should go to the screening and subsequent interventions focusing on the frailty components difficulty in walking, feeling down and lack of social support.
在一项纵向研究中，评估 15 项蒂尔堡虚弱指标（TFI）自我报告问卷的组成部分对社区居住的老年人生活质量领域（身体健康、心理、社会关系和环境）的预测效度。
在荷兰，2008 年对 484 名 75 岁及以上的社区居住者进行了 TFI 组成部分的预测效度测试（响应率为 42%）。所有受访者的一部分在两年后参加了 2010 年的研究（n=261，54%），其中这些受访者的一部分在 2012 年再次参加了研究（n=196，75%）。WHOQOL-BREF 用于测量四个生活质量领域。
四个身体虚弱组成部分（身体不健康、维持平衡困难、行走困难和身体疲劳）、一个心理虚弱组成部分（情绪低落）和一个社会虚弱组成部分（缺乏社会支持）预测了未来生活质量领域的得分，即使在控制了背景特征和疾病之后。
这项纵向研究表明，身体虚弱以及心理和社会虚弱成分都可以预测生活质量。这一发现强调了对虚弱进行多维评估的相关性。为了提高老年人的生活质量，应特别关注行走困难、情绪低落和缺乏社会支持等虚弱成分的筛查和后续干预。
