Peer Motivation Coaches, Social Media-based Support Group, and Behavior Change Strategies to Decrease Prolonged Sitting and Increase Moderate Exercise Snacks

Tweet4Wellness: a Social-media Based Support Group and Peer Motivation Coaches Approach to Decrease Prolonged Sitting and Increase Moderate Exercise Snacks

The MOV'D (Move Often eVery Day) intervention is a remotely-delivered, peer-supported intervention that delivers exercise snack (2-5 minutes of moderate to vigorous activity) and behavior change technique (BCT) videos to a private social media support group with the goal of interrupting prolonged sitting at work with MVPA minutes.

The preliminary efficacy, feasibility, and acceptability trial will test the effects of MOV'D, a socially-supported, evidence-based behavior change technique educational and behavioral intervention to increase the number of active hours (an indirect measure of prolonged sitting bouts) (Hypothesis 1) and number of MVPA minutes (Hypothesis 2). This pilot will gather important estimates of the effect sizes, the variance, and covariance of the primary outcomes to calculate the sample size needed to power a larger fully powered RCT.

Study Overview

• Status: Completed
• Conditions: Sedentary Behavior; Physical Inactivity
• Intervention / Treatment: Behavioral: Fitbit Self-Monitoring; Behavioral: MOV'D (Move Often eVery Day)

Detailed Description

Prolonged sitting and inadequate moderate to vigorous intensity physical activity (MVPA) are pervasive risk factors for cardiovascular disease (CVD). Recent research has shown that some benefits of moderate to vigorous physical activity can be accrued in motivationally accessible short, 2-5 minute bouts throughout the day rather than needing to be a single, longer, continuous bout. The MOV'D intervention is a novel, remotely-delivered, social-media-based intervention to interrupt prolonged sitting with short bouts of MVPA, compared with a Fitbit-only control. The investigators will randomly assign participants to either MOV'D or a Fitbit only control for one month, with a one-month follow-up, to compare immediate and prolonged effects of treatment on number of workday hours with activity break and number of MVPA minutes.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Active Comparator: Fitbit-Only Self-Monitoring; Control participants will be sent a Fitbit and study-provided account and will self-monitor physical activity for the duration of the study period (2 months).	Behavioral: Fitbit Self-Monitoring; All participants receive a Fitbit and are told to monitor their physical activity for the duration of the study period.
Experimental: MOV'D plus Fitbit Self-Monitoring; Treatment participants will be sent a Fitbit and study-provided account, and assigned to a private, study-created Twitter support group of 10 participants. Within the private group of 10, each participant is also further paired with a peer to be that person's peer coach, setting weekly exercise snack goals and practicing behavior change techniques.	Behavioral: Fitbit Self-Monitoring; All participants receive a Fitbit and are told to monitor their physical activity for the duration of the study period.; Behavioral: MOV'D (Move Often eVery Day); The MOV'D intervention is a remotely-delivered, peer-supported intervention that delivers exercise snack (2-5 minutes of moderate to vigorous activity) and behavior change technique (BCT) videos to a private social media support group with the goal of interrupting prolonged sitting at work with MVPA minutes.

Change in average workday MVPA minutes at post-intervention	Average minutes of moderate to vigorous minutes, or minutes above 3 METs per workday (of five) at	5 days at baseline, 5 days after 1 month treatment

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
