Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is designed to evaluate the feasibility and provide preliminary evidence for efficacy of a 12-week contingency management intervention to promote weight loss in overweight and obese low income adults in a community-based clinic. The study has three primary goals: (a) to determine if the contingency management treatment can be effectively applied to a new application, weight loss; (b) to obtain preliminary evidence for contingency management's efficacy in promoting weight loss and improving treatment retention, diet quality, physical activity levels, and self efficacy; and (c) to identify barriers and challenges to implementing contingency management for weight loss among low income patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A

Participants assigned to Group A will receive the DPP manual (Wing \& Gillis, 1996), a behavioral weight-loss program with demonstrated efficacy in facilitating weight loss. Participants in Group A will be instructed to read a section of the manual each week and complete suggested activities. They will also meet with the research staff once a week for weigh-in and supportive counseling.

Group Type ACTIVE_COMPARATOR

weight loss manual-guided individual therapy sessions

Intervention Type BEHAVIORAL

once weekly counseling session with research staff

B

Participants assigned to Group B will receive the DPP manual and will meet with research staff each week for weigh-in and supportive counseling. They will also receive contingency management or the opportunity to earn draws with the chance of winning prizes for losing weight and completing healthy activities.
