- NCT05796141
- Lead Sponsor
- University of Connecticut
- Brief Summary
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).

- Primary Outcome Measures
Name Time Method Body Weight (kg) Baseline to 6 months Weight change from baseline to 6 months. Weight will be objectively measured on a digital scale in the participant's home and weight change will be calculated.
- Secondary Outcome Measures
Name Time Method Transactive Density Baseline, 3 months, 6 months Interdependence of partners will be measured with the Inclusion of Others in the Self Scale at baseline, 3, and 6 months.
Physical Activity (Paffenbarger Physical Activity Questionnaire) Baseline, 3 months, 6 months Physical activity will be assessed using the Paffenbarger Physical Activity Questionnaire at baseline and 3 months as a hypothesized behavioral mediator and at 6 months as a secondary outcome measure.
Dietary Intake Baseline, 3 months, 6 months Dietary intake will be assessed at baseline and 3 months as a hypothesized behavioral mediator and at 6 months as a secondary outcome measure.
Home Food Environment (Household Food Inventory) Baseline, 3 months, 6 months The home food environment will be measured with the Household Food Inventory, administered at baseline, 3, and 6 months.
Goal Coordination (Wingrove Goal Coordination Scale) Baseline, 3 months, 6 months Goal coordination (the extent to which partners integrate and align their weight management goals) will be measured with the Wingrove Goal Coordination Scale at baseline, 3, and 6 months.
Shared Goal Representation Baseline, 3 months, 6 months The Important Others Questionnaire will be used to capture shared goal representation at baseline, 3, and 6 months.
Home Exercise Environment (Exercise Environment Questionnaire) Baseline, 3 months, 6 months The home exercise environment will be measured with the Exercise Environment Questionnaire, administered at baseline, 3, and 6 months.
