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).

|---|---|---|---|---|
| Core Behavioral Weight Loss (BWL) intervention | Behavioral | Behavioral weight loss core (lessons, self weighing, self-monitoring, individual action planning, feedback and progress check ins) |
| Measure | Description | Time Frame |
|---|---|---|
| Body Weight (kg) | 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. | Baseline to 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Goal Coordination (Wingrove Goal Coordination Scale) | 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. | Baseline, 3 months, 6 months |

|
| Dyadic Action Planning | Behavioral | Participants will develop dyadic action plans together. |
|
| Joint Feedback | Behavioral | Participants will see data on their partner's progress, in addition to their own weight and behavioral data. |
|
| Autonomy Support Training | Behavioral | Participants will receive training in how to create an autonomy supportive environment within their marriage/partnership. |
|
| Home Environment Modifications | Behavioral | Participants will be trained in how to structure their home environment to support health behavior. |
|
Interdependence of partners will be measured with the Inclusion of Others in the Self Scale at baseline, 3, and 6 months. |
| Baseline, 3 months, 6 months |
| Shared Goal Representation | The Important Others Questionnaire will be used to capture shared goal representation at baseline, 3, and 6 months. | Baseline, 3 months, 6 months |
| Home Food Environment (Household Food Inventory) | The home food environment will be measured with the Household Food Inventory, administered at baseline, 3, and 6 months. | Baseline, 3 months, 6 months |
| Home Exercise Environment (Exercise Environment Questionnaire) | The home exercise environment will be measured with the Exercise Environment Questionnaire, administered at baseline, 3, and 6 months. | Baseline, 3 months, 6 months |
| Dietary Intake | Dietary intake will be assessed at baseline and 3 months as a hypothesized behavioral mediator and at 6 months as a secondary outcome measure. | Baseline, 3 months, 6 months |
| Physical Activity (Paffenbarger Physical Activity Questionnaire) | 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. | Baseline, 3 months, 6 months |
