The purpose of this study was to test reliability and validity of the Physical Resilience Scale.
A single-group repeated measure design was used and 130 older adults from three different housing sites participated. Participants completed the Physical Resilience Scale, Hardy-Gill Resilience Scale, 14-item Resilience Scale, 5-item Geriatric Depression Scale, and the Yale Physical Activity Survey at baseline and again 2 weeks later.
There was evidence of validity of the Physical Resilience Scale based on model testing using a Rasch Analysis and significant correlations with commonly used general resilience measures. Evidence of reliability was supported based on a Separation Index and alpha coefficient of .89 and test-retest reliability with correlations between testing times of .73.
Future use of the Physical Resilience Scale should consider adding more challenging items to better differentiate those particularly high in physical resilience.
本研究旨在测试身体韧性量表的信度和效度。
采用单组重复测量设计，共有来自三个不同居住地点的 130 名老年人参与。参与者在基线时和两周后分别完成身体韧性量表、哈迪-吉尔韧性量表、14 项韧性量表、5 项老年抑郁量表和耶鲁体力活动调查。
基于使用 RASCH 分析的模型测试，身体韧性量表具有有效性的证据，并且与常用的一般韧性测量指标显著相关。基于分离指数和 α 系数为.89 以及测试 - 重测信度的证据得到支持，两次测试之间的相关性为.73。
未来使用身体韧性量表时，应考虑增加更具挑战性的项目，以更好地区分那些身体韧性特别高的人。
