Brief Summary

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

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

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

Internet Obesity Treatment

Participants will attend weekly class sessions on line and track food and exercise in an on-line journal.

Group Type ACTIVE_COMPARATOR

Internet Obesity Treatment

Intervention Type BEHAVIORAL

Participants will engage in self monitoring, will receive skills training to help cope with environmental triggers, and will receive nutrition advice.

Internet Obesity Treatment with MI

Participants will attend weekly classes on line, record food and exercise in an on-line journal, and will have no more than 6 individual motivational interviewing sessions.

Group Type EXPERIMENTAL

Internet Obesity Treatment with MI

Intervention Type BEHAVIORAL

In addition to weekly group meetings, self-monitoring through recording calorie and fat intake daily as well as exercise, participants will meet one-on-one with an MI counselor on-line in order to augment an individual's motivation to change behavior.

Contingent MI

Intervention is the same as for the MI arm, however participants will only receive MI if meeting certain treatment participation conditions.

Group Type EXPERIMENTAL

Contingent MI

Intervention Type BEHAVIORAL

Participants will attend weekly behavioral internet meetings. They may or may not receive Motivational Interviewing depending on their class attendance.
