Understanding of prefrailty's relationship with limitations in activities of daily living (ADLs) moderated by psychological resilience is needed, as resilience might support ADLs' maintenance and thus protect against frailty. Therefore, this study aims to analyze the influence of psychological resilience (using the Connor-Davidson Resilience Scale; CD-RISC) on the relation between ADLs and frailty status of older individuals (i.e. prefrail versus robust).
Cross-sectional design.
UZ Brussels, Belgium.
Robust (Fried 0/4;n = 214; Age = 82.3 ± 2.1yrs) and prefrail (Fried 1-2/4; n = 191; Age = 83.8 ±3.2yrs) community-dwelling older individuals were included.
Frailty scores were obtained from weight loss, exhaustion, gait speed, and grip strength. A total Disability Index (DI) expressed dependency for basic (b-), instrumental (i-), and advanced (a-)ADLs. Mediation was investigated by estimating direct and indirect effects of all levels of ADLs and CD-RISC total score on prefrailty/robustness using a stepwise multiple regression approach.
Prefrailty/robustness significantly correlated with a-ADL-DI (point-biserial correlation (r) = 0.098; p<0.05). Adjusted for age and gender, the a-ADL-DI (p<0.05) had a significant protective direct effect against prefrailty. No effects were found with the CD-RISC total score.
Less limitation in a-ADLs is a directly correlated factor of prefrailty and might represent a higher likelihood of robustness.
由于心理韧性可能有助于维持日常生活活动能力（ADLs），从而预防衰弱，因此需要了解由心理韧性调节的脆弱前期与日常生活活动受限之间的关系。因此，本研究旨在分析心理韧性（使用康纳-戴维森韧性量表；CD-RISC）对老年人ADLs与衰弱状态（即脆弱前期与健康状态）之间关系的影响。
横断面设计。
比利时布鲁塞尔大学医院。
纳入了健康（弗里德衰弱量表评分为0/4；n = 214；年龄 = 82.3 ± 2.1岁）和脆弱前期（弗里德衰弱量表评分为1 - 2/4；n = 191；年龄 = 83.8 ± 3.2岁）的社区居住老年人。
通过体重减轻、疲劳、步速和握力获得衰弱评分。总残疾指数（DI）表示对基本（b-）、工具性（i-）和高级（a-）ADLs的依赖程度。使用逐步多元回归方法，通过估计ADLs各水平和CD-RISC总分对脆弱前期/健康状态的直接和间接影响来研究中介作用。
脆弱前期/健康状态与a-ADL-DI显著相关（点二列相关系数（r） = 0.098；p<0.05）。在调整年龄和性别后，a-ADL-DI（p<0.05）对脆弱前期有显著的保护性直接影响。未发现CD-RISC总分有影响。
a-ADLs受限较少是脆弱前期的直接相关因素，可能代表更高的健康可能性。
