MoST-Influenced Behavioral Intervention for Walking

Summary

This study is a randomized, factorial experiment using the basic Science of Behavior Change (SOBC) approach to efficiently test the effects of four distinct behavior change techniques (BCTs), goal setting, action planning, self- monitoring and feedback, thought to engage one key behavioral mechanism of action (MoA) for improving daily walking by at least 1000 steps per day in persons who have been objectively verified as sedentary and are at risk for cardiovascular disease.

Interventions

BEHAVIORAL

Goal Setting

Individuals will receive daily text messages that include the Goal Setting behavior change technique (BCT) with the goal of increasing daily walking by 1,000 more steps than their baseline average step count. An example of the Goal Setting BCT is "Is your goal to walk an extra 1,000 steps more than your baseline average?".

BEHAVIORAL

Action Planning

Individuals will receive daily text messages that include the Action Planning behavior change technique (BCT) with the goal of increasing daily walking by 1,000 more steps than their baseline average step count. An example of the Action Planning BCT is "Take one minute and plan for today how, where and when you can walk an extra 1,000 steps more than your baseline average. Have you planned for today?"

BEHAVIORAL

Self-Monitoring of Behavior

Individuals will receive daily text messages that include the Self-Monitoring behavior change technique (BCT) with the goal of increasing daily walking by 1,000 more steps than their baseline average step count. An example of the Self-Monitoring BCT is "Check your fitbit for yesterday. Type in the number of steps you did yesterday."

BEHAVIORAL

Feedback on Behavior

Individuals will receive daily text messages that include the Feedback behavior change technique (BCT) with the goal of increasing daily walking by 1,000 more steps than their baseline average step count. An example of the Feedback BCT is "Your goal is to walk 1000 steps more than your baseline average. Yesterday you did not meet your goal. If you think this is incorrect you can check your step count from yesterday on your Fitbit app to confirm. "
