Details and patient eligibility

About

The goal of this project is to investigate how to enhance the effects of an online-only (mHealth) couples weight loss program. This study will use an innovative methodological framework, the Multiphase Optimization Strategy (MOST), to test four different strategies for weight loss and partner support in addition to a core intervention (i.e., dyadic action planning, joint feedback on goal progress, autonomy support training, and home environment modifications).

Enrollment: 736 estimated patients

Sex: All

Ages: 18 to 75 years old

Volunteers: No Healthy Volunteers
