Study Overview
Brief Summary
This study involves an evaluation of the role of domestic partner support in a comprehensive weight loss initiation and maintenance program.
Detailed Description
Couples will be randomized to a comprehensive weight program directed at patients alone or involving their partners. In months 1-6, all patients will receive group-based weight loss program. In months 7-18, all patients will receive a telephone-based weight loss maintenance intervention. In the partner-assisted arm only, partners will participate in the intervention, learning and practicing communication skills and support strategies. In months 19-24, intervention will be withdrawn to examine sustainability of effects.
Due to COVID-19, option of doing screening and outcome assessment visits and attending the group classes (including exercise) remotely via a video conference may be available. COVID-19 survey will be administered every 3 month starting at screening/enrollment visit.
