Studying How Different Types of Weekly Feedback Affect Weight Loss in Adults Using a New Self-Monitoring System

What this Trial Is About

Researchers are evaluating how weekly feedback messages can best support people in a weight loss program. This study focuses on adults with obesity or overweight conditions and aims to learn how different types of feedback influence behaviors and weight loss. It is a micro-randomized factorial trial designed to improve self-monitoring feedback in a behavioral weight management intervention. Participants will first attend a 60-minute Weight Loss 101 session covering basic weight loss education and skills. They will learn to use tools to track their food intake, physical activity, and weight. After a one-week run-in period, participants will receive weekly feedback messages created by trained interventionists. These messages will either provide positive reinforcement alone or combine positive reinforcement with suggestions for areas of change. Throughout the 17-week study, participants will regularly record their weight, diet, and physical activity using study-provided tools. Researchers will measure weight changes weekly and assess how often participants self-monitor their weight, diet, and activity. They will also track calorie intake, goal achievement, and physical activity minutes. The study includes monitoring adherence to self-monitoring and message receipt, with safety and progress evaluated during the trial.
