• Conditions: Overweight and Obesity

• Registration Number: 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).

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: FACTORIAL

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.
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.
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.
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.
