Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
