Summary

The purpose of this research study is to learn how to identify the most effective ways to provide weekly feedback on participants' progress toward intervention goals during a weight loss program.

Detailed description

This micro-randomized factorial trial is designed to provide information about how to optimize self-monitoring feedback within a behavioral weight management intervention. All participants will attend a "Weight Loss 101" session that covers foundational weight loss education and behavioral skills training. During this session, they will also learn how to use study-provided tools to track their dietary intake, physical activity, and weight. Each weekly feedback message will be composed by a trained interventionist. Participants will be randomized each week to one of the two conditions to examine how the tone and composition of feedback messages impact participant behaviors and weight loss. The main questions that this study aims to answer are: * How does the composition of supportive feedback and ideas for potential changes in dietary or physical activity behaviors impact weight loss. * How is this feedback affected by individual or contextual factors?

Conditions

• Obesity & Overweight
• Obesity (Disorder)

Interventions

Type	Name	Description
BEHAVIORAL	Positive Reinforcement	Feedback composed by a study interventionist that focuses exclusively on positively reinforcing the participant's progress toward achieving their goals.
BEHAVIORAL	Positive Reinforcement + Areas for Change	Feedback provided by a study interventionist that combines positive reinforcement of the participant's progress with constructive guidance on areas for improvement to support successful goal attainment.
