The goal of this research is to examine the addition of a digitally delivered social support training approach to an existing digital program designed to promote a physically active lifestyle among self-selected teams of adults who are not meeting physical activity guidelines. The main aims are to:
Self-selected teams of 3-8 insufficiently active adults (about 60 teams comprised of a total of 300 participants) will be randomized to receive either a 3-month, theory-based, technology-delivered physical activity intervention characterized by personalized physical activity goals, a wearable physical activity tracker, electronic feedback, and behavior change modules embedded within a mobile-compatible app (Team) or the same intervention plus digitally delivered social support training (Team+Training). Outcome assessments will be completed at baseline, 3, and 12 months.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Team Program | Active Comparator | Teams randomized to this arm will be provided with personal physical activity goals focused on moderate-to-vigorous intensity aerobic physical activity minutes and steps. They will also be provided with a Fitibt wearable smartwatch for self-monitoring physical activity, receive weekly electronic feedback for the first month of the intervention about their physical activity progress, and have access to a mobile-compatible study web app containing behavior change content and physical activity progress information. |
|
| Team+Training Program | Experimental | Teams randomized to this arm will receive the same intervention as the Team study arm, as well as digitally delivered social support training. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Mobile STRIDES app (psychoeducation features) | Behavioral | Twelve theory-based physical activity behavior change lessons/modules during the course of the 3-month intervention. |

| Measure | Description | Time Frame |
|---|---|---|
| Change in minutes per week of moderate-to-vigorous intensity aerobic physical activity (MVPA) at 3 months | Change in minutes per week of moderate-to-vigorous intensity aerobic physical activity (MVPA) from baseline to 3 months as measured by accelerometer | Baseline and 3 months |
| Measure | Description | Time Frame |
|---|---|---|
| Change in minutes per week of moderate-to-vigorous intensity aerobic physical activity (MVPA) at 12 months | Change in minutes per week of moderate-to-vigorous intensity aerobic physical activity (MVPA) from 3 months to 12 months as measured by accelerometer | 3 months and 12 months |
| Change in supportive accountability at 3 months |
| Measure | Description | Time Frame |
|---|---|---|
| Mediation analysis of social support on moderate-to-vigorous intensity aerobic physical activity | A mediation analysis will be conducted to explore whether social support mediates increased (at 3 months) and sustained (at 12 months) moderate-to-vigorous intensity aerobic physical activity within the overall study sample. The Social Support for Healthy Behaviors Questionnaire (physical activity support scale) adapted to query about one's team will be used to measure social support at baseline, 3 months, and 12 months. Items are scored using response options on a 5-point scale which ranges from almost never/not applicable to almost always, with higher mean scores indicating more support. Minutes per week of moderate-to-vigorous intensity aerobic physical activity will be measured using an accelerometer at baseline, 3 months, and 12 months. These data will facilitate the construction of mediation models. |

| Mobile STRIDES app (self-regulation features) | Behavioral | Personalized physical activity goals focused on moderate-to-vigorous intensity aerobic physical activity and steps. Physical activity (tracked with a Fitbit wearable smartwatch and synced with the Mobile STRIDES app) tracking component, displaying team and individual progress. Weekly individualized feedback messages crafted by a trained professional for the first month of the intervention. |
|
| Mobile STRIDES app (social support training features) | Behavioral | For the experimental group, the Mobile STRIDES app also includes five social support training lessons/modules (during the course of the 3-month intervention) focused on providing guidance related to effective communication when exchanging social support for physical activity within a team. In addition, six team feedback messages will be delivered to respective teams throughout the course of the 3-month intervention to reinforce content taught via the training lessons/modules. A weekly poll will also be administered that complements the social support training lessons, with cumulative results displayed. |

Support Accountability Inventory adapted for physical activity and to query about one's team. Items rated on a Likert scale response format ranging from 1 (Strongly Disagree) to 7 (Strongly Agree) with a not applicable option, with higher total scores indicating higher perceived supportive accountability. |
| Baseline and 3 months |
| Change in motivation at 3 months | Treatment Self-Regulation Questionnaire adapted for physical activity. Items scored using a 7-point Likert scale (1 = not at all to 7 = very true). Higher scores on the Autonomous Subscale indicate greater autonomous motivations for behavior change and higher scores on the Controlled Motivations subscale indicate higher controlled regulation. | Baseline and 3 months |
| Change in supportive accountability at 12 months | Support Accountability Inventory adapted for physical activity and to query about one's team. Items rated on a Likert scale response format ranging from 1 (Strongly Disagree) to 7 (Strongly Agree) with a not applicable option, with higher total scores indicating higher perceived supportive accountability. | 3 months and 12 months |
| Change in motivation at 12 months | Treatment Self-Regulation Questionnaire adapted for physical activity. Items scored using a 7-point Likert scale (1 = not at all to 7 = very true). Higher scores on the Autonomous Subscale indicate greater autonomous motivations for behavior change and higher scores on the Controlled Motivations subscale indicate higher controlled regulation. | 3 months and 12 months |
| Change in autonomy support at 3 months | Important Other Climate Questionnaire adapted for physical activity and to query about one's team. Items rated on a Likert scale response format ranging from 1 (Strongly Disagree) to 7 (Strongly Agree) with a not applicable option, with higher total scores indicating higher perceived autonomy support. | Baseline and 3 months |
