简要总结
The goal of this study is to develop an optimized intervention for reducing leisure sedentary screen time (SST) in middle-aged adults with overweight or obesity. Investigators will use the multiphase optimization (MOST) framework to conduct a highly efficient full-factorial experimental study to simultaneously test the main effects for each of three intervention components (LOCKOUT, TEXT, EARN) and their interactions (e.g., TEXT+EARN; LOCKOUT+EARN+TEXT) over 16 weeks.
详细描述
Primary Aim: To identify which component(s) from three components under consideration for inclusion in StandUPTV reduce SST by >60 min per day per day at 16 weeks. The three components tested will be: (a) LOCKOUT (no vs. yes); (b) TEXT (no vs. yes); and (c) EARN (no vs. yes). The investigators will use a highly efficient experimental strategy to detect effects of individual components as well as all two- and three-way interactions.
The secondary aim of this study is to examine how reductions in SST displace time into other active behaviors, i.e., light-intensity physical activity (LPA), moderate-to vigorous physical activity (MVPA) and activity type (e.g., housework, walking, exercise behaviors). The investigators will use both device-based (activPAL3c) and self-report (ACT24) measures to understand whether SST displacement can increase active behaviors, particularly MVPA.
