Brief summary
The goal of the proposed project is to test the effectiveness of an intervention (Connect4Health Engage) focused on motivating and guiding patients to use empirically supported, freely available online tools for weight loss. A randomized trial will be conducted in primary care clinics. Fifteen to twenty PCPs will be recruited, followed by 453 patients. Patients will complete either the 52-week Connect4Health Engage intervention or Connect4Health Discover, an educational control.
