Brief Summary

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

The major goal of this project is to evaluate an innovative approach to obesity involving modification of the home environment. The project also will evaluate if home environment modification is more effective when supplemented with distress tolerance and related skills training.
