Mobility as a multidimensional concept has rarely been examined as a day-to-day varying phenomenon in its within-person association with older adults' daily well-being. This study examined associations between daily mobility and daily well-being in community-dwelling older adults with a set of GPS-derived mobility indicators that were representative of older adults' daily mobility.
Participants wore a custom-built mobile GPS sensor ("uTrail") and completed smartphone-based experience sampling questionnaires on momentary affective states (7 times per day) and daily life satisfaction (in the evening). Analyses included data across 947 days from 109 Swiss older adults aged 65-89 years.
Multilevel modeling showed that, within persons, a day with a larger life space area, more time spent in passive transport modes, and a higher number of different locations was associated with higher daily life satisfaction but not daily positive or negative affect. Follow-up analysis showed that the daily maximum distance from home was positively associated with daily life satisfaction, providing a first indication that exposure to non-habitual environments might be a possible underlying mechanism to explain the effects of mobility.
Traveling a long distance away from home and visiting diverse locations may be a way to improve life satisfaction. Results are discussed in the context of research on healthy aging.
移动性作为一个多维概念，很少在个体内部与老年人的日常幸福感方面作为日常变化的现象进行研究。本研究使用一套代表老年人日常移动性的 GPS 衍生移动性指标，考察了社区居住的老年人日常移动性与日常幸福感之间的关系。
参与者佩戴了一个定制的移动 GPS 传感器（“uTrail”），并通过智能手机完成了关于瞬间情感状态（每天 7 次）和日常生活满意度（晚上）的体验抽样问卷。分析包括来自 109 名年龄在 65-89 岁的瑞士老年人的 947 天的数据。
多层次模型显示，在个体内部，生活空间面积较大、被动交通模式花费时间较多、不同地点数量较多的一天与更高的日常生活满意度相关，但与日常积极或消极情绪无关。后续分析表明，每天离家的最大距离与日常生活满意度呈正相关，这首次表明接触非习惯性环境可能是解释移动性影响的一个潜在机制。
远离家的长途旅行和访问不同的地方可能是提高生活满意度的一种方式。研究结果在健康老龄化研究的背景下进行了讨论。
