Internet-based weight control programs have been shown effective in producing weight loss,
but in-person delivery of behavioral weight control produces significantly greater weight
loss than on-line delivery of the same program. Motivational Interviewing has been shown to
increase weight loss when delivered as an adjunct to in-person weight loss programs but has
not been examined in conjunction with web-based obesity treatment. Therefore, the overall
goal of this project is to determine if the addition of on-line Motivational Interviewing to
a web-based group behavioral obesity treatment program will augment weight loss outcomes.

This randomized controlled trial is designed to determine whether weight losses in a group
behavioral weight loss intervention conducted over the Internet are increased with the
inclusion of individual, online MI sessions. All participants will receive the same online
6-month group-based behavioral weight loss program followed by 12 months of weight
maintenance. Overweight and obese adults at two study sties (N=426) will be randomized to (1)
Internet intervention; or 2) Internet intervention with individual MI sessions occurring at
three month intervals on a fixed schedule (Internet+MI-Fixed). Assessments will be conducted
every six months and will include measures of body weight and height, diet and exercise
behaviors, Quality of Life, adherence measures (eg., attendance, compliance with
self-monitoring), social influence components, motivation, treatment satisfaction,
demographic data and descriptive information regarding use of website components. A third arm
was added for the final 3 intervention cohorts. All participants received the program as
described above with the addition of motivational interviewing contingent on participants'
attendance in classes.
