Brief Summary

High quality behavioral weight loss programs are not widely accessible. The Internet offers one way to deliver health behavior programs to a wider audience. However, effective weight loss treatments are intensive and program delivery over the Internet may not be capable of duplicating the level of engagement typically generated during traditional in-person treatment. The goal of this study is to test the effectiveness of three weight loss interventions: Internet alone, Internet+periodic in-person support, and in-person alone. The investigators hypothesize that the in-person and internet+in-person interventions will produce better weight loss and maintenance than the internet only group.

Conditions

Overweight; Obesity

Outcome Measures

Primary Outcomes (1)

• Body Mass Index or body weight change

  0, 6, 12, 18 month time points

Secondary Outcomes (1)

• Social support, diet, exercise, adherence to treatment components

  0, 6, 12, 18 months

Study Arms (3)

1

EXPERIMENTAL

Individuals in this arm receive a 6 month behavioral weight loss intervention delivered on-line. Groups meet via a web chat weekly for 24 weeks and monthly for the following 12 months.

Behavioral: internet, in-person and internet+in-person

2

EXPERIMENTAL

In-person; Individuals in the in-person condition attend weekly group behavioral weight loss sessions for 24 weeks and then monthly sessions for the following 12 months.

Behavioral: internet, in-person and internet+in-person

3

EXPERIMENTAL

In-person+internet; Individuals in this condition receive a behavioral weight loss intervention over the internet weekly for 24 weeks and monthly for the following 12 months. Every month during the first 24 weeks and every third month during the following year they have an in-person meeting.

Behavioral: internet, in-person and internet+in-person

Interventions

internet, in-person and internet+in-person BEHAVIORAL

All participants receive an 18 month behavioral weight loss program that meets weekly for the first 6 months and monthly for the next year.
