OBJECTIVE
The aim of the study was to explore the association between fear of falling (FOF), dual-task ability during a mobility task, and the activities of daily living (ADL) in a sample of older adults.
METHODS
Seventy-six older adults (mean age M = 70.87 ± 5.16 years) participated in the study. Data on FOF (using the Falls Self-Efficacy Scale-International), walking ability during both single- and dual-task performances and ADL were collected.
RESULTS
Mediation analysis demonstrated the mediation effect of dual-task ability (β = 0.238, p = 0.011) between FOF and ADL level (β = 0.559, p < 0.001). Moreover, significantly lower performances were observed during dual-task condition [F (2, 73) = 7.386, p < 0.001], and lower ADL levels were also found in older adults with FOF [F (2, 73) = 13.734, p < 0.001].
CONCLUSION
The study underlines the relationship between FOF, dual-task ability and ADL level. These results could be used to develop specific intervention programmes for successful ageing.
目的
本研究旨在探讨恐惧跌倒（FOF）、移动任务中的双重任务能力与老年人日常活动能力（ADL）之间的关联。
方法
76 名老年人（平均年龄 M=70.87±5.16 岁）参与了这项研究。收集了 FOF（使用跌倒自我效能感量表-国际版）、单任务和双重任务行走能力以及 ADL 数据。
结果
中介分析表明，FOF 和 ADL 水平之间存在双重任务能力的中介效应（β=0.238，p=0.011）。此外，在双重任务条件下观察到的表现明显较差[F（2,73）=7.386，p<0.001]，FOF 老年人的 ADL 水平也较低[F（2,73）=13.734，p<0.001]。
结论
本研究强调了 FOF、双重任务能力和 ADL 水平之间的关系。这些结果可用于制定成功老龄化的特定干预计划。
