StandUPTV: Reducing Sedentary Screen Time in Adults

Completed · Not applicable

Conditions studied: Sedentary Behavior, Screen Time, Physical Activity, Sleep

In brief

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.
