ABSTRACT

The purpose of this study is to identify the effect of a tailored domain-specific intervention using contextual information about sedentary behavior to reduce sedentary time. A total of 40 participants (i.e., general adults) were randomly assigned to three groups (i.e., tailored domain-specific intervention, standard intervention and control). Behavioral strategies included educational meeting and materials, goal setting and feedback, and self-monitoring for the two intervention groups. Additionally, the contextual information was given to the tailored domain-specific intervention group. Sedentary time was measured by accelerometers at baseline, firstand second intervention week, and contextual information about their sedentary behavior was obtained from the Sedentary Behavior Record instrument. A Bayesian repeated measures ANOVA was conducted. Thirty-six participants were included in this study. There was an evidence of interaction effect between group and time (BF₁₀ = 8.17). In the tailored domain-specific intervention group, sedentary time at the first intervention week (BF₁₀ = 19.09) and at the second intervention week (BF₁₀ = 86.39) was less than the sedentary time at baseline. The tailored domain-specific intervention using contextual information was effective, reducing sedentary time.

摘要

本研究的目的是使用有关久坐行为的上下文信息来减少久坐时间，从而确定量身定制的针对特定领域的干预措施的效果。总共40名参与者（即普通成年人）被随机分为三组（即，针对特定领域的干预，标准干预和对照）。行为策略包括教育会议和材料，目标设定和反馈以及对两个干预组的自我监控。此外，将上下文信息提供给量身定制的特定领域干预组。静坐时间是在基线，第一和第二干预周通过加速计测量的，并且从久坐行为记录仪中获取了有关其久坐行为的上下文信息。进行了贝叶斯重复测量方差分析。这项研究包括了36名参与者。有证据表明组与时间之间存在交互作用（BF₁₀  = 8.17）。在针对特定领域的定制干预组中，第一个干预周（BF ₁₀  = 19.09）和第二个干预周（BF ₁₀  = 86.39）的久坐时间少于基线时的久坐时间。使用上下文信息量身定制的针对特定领域的干预是有效的，从而减少了久坐时间。
