Brief Summary

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.

Conditions

Sedentary Behavior; Physical Inactivity

Outcome Measures

Primary Outcomes (2)

• Change in average active workday hours at post-intervention

  Average hours with \>2 min of MVPA (Moderate to Vigorous Physical Activity) or 250 steps between 8 AM - 7 PM per workday (of five); proxy for prolonged sitting time

  5 days at baseline, 5 days after 1 month treatment

• 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 Outcomes (2)

• Change in average active workday hours at follow-up

  5 days at baseline, 5 days post 1-month follow-up

• Change in average workday MVPA minutes at follow-up

  5 days at baseline, 5 days post 1-month follow-up

Study Arms (2)

Fitbit-Only Self-Monitoring

ACTIVE COMPARATOR

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

MOV'D plus Fitbit Self-Monitoring

EXPERIMENTAL

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: MOV'D (Move Often eVery Day); Behavioral: Fitbit Self-Monitoring

Interventions

MOV'D (Move Often eVery Day) BEHAVIORAL

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.

MOV'D plus Fitbit Self-Monitoring

Fitbit Self-Monitoring BEHAVIORAL

All participants receive a Fitbit and are told to monitor their physical activity for the duration of the study period.

Model Details: This is preliminary efficacy, acceptability, and feasibility pilot with a randomized controlled design. The preliminary efficacy pilot 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). The 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 trial.
