Way to Be Active IV (Framing vs Incentives)

Study Overview
=================
Brief Summary
-----------------
Employers are increasingly looking for opportunities to motivate sedentary employees to become more physically active. Workplace walking programs have had mixed success and typically show most improvement among participants that are already fairly active at a baseline. The goal of this study is to determine whether a financial incentive program can motivate sedentary employees to increase the number of steps they walk per day to meet a minimum threshold. The primary outcome measure is the proportion of days a minimum activity of 7000 steps or more is achieved. Outcomes will be assessed each week for 3 months using incentives followed by 3 months of follow-up without incentives. Secondary outcomes will include the average steps walked per day.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Feedback 50th Percentile<br>At the end of each week, participants will be told the average daily step count for their team for the previous week. They will also be told the average for the 50th percentile in their arm. | Behavioral: Teams<br> <br> Behavioral: Daily Feedback<br>* Participants will be given daily feedback on whether or not they walked 7000 steps or more the day before.<br>|
| Experimental: Feedback 75th Percentile<br>At the end of each week, participants will be told the average daily step count for their team for the previous week. They will also be told the average for the 75th percentile in their arm. | Behavioral: Teams<br> <br> Behavioral: Framing of feedback<br> <br> Behavioral: Daily Feedback<br>* Participants will be given daily feedback on whether or not they walked 7000 steps or more the day before.<br>|
| Experimental: Feedback 50th Percentile + Lottery<br>At the end of each week, participants will be told the average daily step count for their team for the previous week. They will also be told the average for the 50th percentile in their arm. If their team's average daily step count is ≥ 7000 steps, they'll be eligible to collect winnings from a weekly lottery. Teams whose average daily step count is less than 7000 will receive messages about how much they would have won had the team met its goal. | Behavioral: Financial incentives<br> <br> Behavioral: Teams<br> <br> Behavioral: Daily Feedback<br>* Participants will be given daily feedback on whether or not they walked 7000 steps or more the day before.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Days a Participant Walks 7000 Steps or More | The primary outcome measure is the proportion of days a minimum activity of 7000 steps or more is achieved. Outcomes will be assessed each week for 3 months using incentives followed by 3 months of follow-up without incentives. Below we report the highest mean proportions found. | Throughout 6-month study | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average Number of Steps Per Day | Secondary outcomes include average number of steps per day during the incentive period (first 3 months) and follow-up period (second 3 months). | Throughout the 6-month study |
