Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Internet only
Participants will be required to attend a weekly Internet chat session with your group members and one of the behavioral weight control therapists. Participants will learn the principles of managing eating and exercise behaviors in weekly, hour-long chat sessions and by completing weekly lessons. Participants are asked to self-monitor foods and exercise through the use of a smartphone ap. Participants will wear a tracking device that monitors steps. All participants will be contacted via e-mail individually, by their group leader who will monitor their progress and offer advice and encouragement. Meetings are weekly for 24 weeks and monthly for 12 months.
Internet Only
18 month behavioral weight loss intervention delivered online
Internet + Incentives
Participants are given the same intervention as described for the internet only group, with the exception that they will have the opportunity to earn financial incentives. Financial incentives will be based on participants weight loss, and compliance with certain weight loss behaviors including meeting exercise goals, self-monitoring foods consumed, and daily weighing and reporting.
Internet + Incentives
18 month behavioral weight loss intervention delivered online with the possibility of earning incentives for losing weight and performing weight loss behaviors including monitoring food intake, exercising, and daily weighing
