Trial Summary

What is the purpose of this trial?

Self-monitoring (of weight, intake, and activity) is a core component in evidence-based lifestyle interventions for obesity. Research has shown that interventionist feedback increases adherence to self-monitoring and improves weight loss outcomes; however, little empirical evidence exists on how this feedback should be provided. This research study aims to optimize the provision of self-monitoring feedback.

Treatment Details

Interventions

• Optimizing Self-Monitoring Feedback

Trial Overview The study tests how different components like diet quality, goal setting, calorie goals, and physical activity affect the success of self-monitoring in treating obesity. It aims to find the best way to provide feedback that encourages adherence to these components.

Participant Groups

Group I: Component 4: Goal Setting Experimental Treatment 1 Intervention

Participants will be randomized to either receive or not receive feedback based on weekly goal setting.

Group II: Component 3: Physical Activity Goal Attainment Experimental Treatment 1 Intervention

Participants will be randomized to either receive or not receive feedback based on physical activity goal attainment.

Group III: Component 2: Diet Quality Experimental Treatment 1 Intervention

Participants will be randomized to either receive or not receive feedback based on diet quality.

Group IV: Component 1: Calorie Goal Attainment Experimental Treatment 1 Intervention

Participants will be randomized to either receive or not receive feedback based on calorie goal attainment.
