NCT00714168

Brief Summary

The number of overweight and obese adults in the United States is increasing at a rapid rate. A "stepped-care" weight loss program, which at key times increases the frequency of contact between an individual trying to lose weight and the program staff, may be beneficial for achieving long-term weight loss. This study will compare a standard behavioral weight loss program with a "stepped-care" weight loss program in their abilities to help people who are overweight or obese to lose weight.

Study Arms (2)

1

ACTIVE COMPARATOR

Participants will take part in a standard behavioral weight loss program.

Behavioral: Standard Behavioral Weight Loss Program

2

EXPERIMENTAL

Participants will take part in a stepped-care weight loss program.

Behavioral: Stepped-Care Weight Loss Program

Interventions

This program will include group sessions that will focus on modifying eating and physical activity behaviors to improve weight loss.

1

In this program, increases in the intensity of treatment will be based on participants' abilities to achieve predetermined weight loss goals. Participants will initially receive less contact with program staff. The intensity and/or frequency of contact will then increase at 12-week intervals, based on weight loss progress until a 10% weight loss is attained and maintained. The program will stay constant, unless weight loss drops below the 10% level.

Limitations and Caveats

This study was not designed to test for weight loss equivalency between conditions. This study is unable to determined if an alternative intensity or frequency of intervention steps would be more or less effective for weight loss.
