OBJECTIVES
To identify factors associated with weekly adherence to a 12-week tracker-based activity intervention in older adults.
METHOD
Using generalized linear mixed models in a secondary analysis ( N = 35), we examined factors associated with weekly adherence (defined as wore the Jawbone Up24 tracker for ≥5 days and completed weekly calls). Factors examined included individual characteristics, gave and received virtual support, achieved step goals, barrier and task self-efficacy, and self-comment.
RESULTS
Participants' ( M = 61.7, SD = 5.7) adherence changed from 86% (Week 1) to 74% (Week 12). Achieved the previous week's goal (β = 1.13, p = .01) and received virtual support (β = 0.01, p = .02) significantly increased the odds of weekly adherence.
DISCUSSION
Achieved step goals and received virtual support were associated with improved adherence to our tracker-based activity intervention, which has promising potential to be translated into the clinical setting to promote active lifestyles.
目的
确定与老年人为期 12 周基于追踪器的活动干预每周依从性相关的因素。
方法
在二次分析中使用广义线性混合模型（N=35），我们检查了与每周依从性（定义为佩戴 Jawbone Up24 追踪器≥5 天并完成每周电话呼叫）相关的因素。检查的因素包括个体特征、给予和接受虚拟支持、达到步数目标、障碍和任务自我效能以及自我评价。
结果
参与者的（M=61.7，SD=5.7）依从性从第 1 周的 86%下降到第 12 周的 74%。达到前一周的目标（β=1.13，p=.01）和接受虚拟支持（β=0.01，p=.02）显著增加了每周依从性的几率。
讨论
达到步数目标和接受虚拟支持与提高对我们基于追踪器的活动干预的依从性相关，这具有将其转化为临床环境以促进积极生活方式的巨大潜力。
