A Tailored Domain-specific Intervention Using Contextual Information about Sedentary Behavior to Reduce Sedentary Time: A Bayesian Approach

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.
