Way to Be Active 2 (Lotteries)

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. Our primary outcome measure is the proportion of days a minimum activity of 7000 steps or more is achieved. We will assess outcomes 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 |
| --- | --- |
| No Intervention: Control<br>Participants receive either an email or text message daily (based on the participant's preference) stating whether the participant achieved the 7000 step goal during the previous day. | |
| Experimental: Basic Lottery<br>Participants receive either an email or text message daily (based on the participant's preference) stating whether the participant achieved the 7000 step goal during the previous day. Each day a lottery will be held, and participants will be eligible to collect monetary rewards only if the participant met the step goal the day before. The names of the winners will be announced during each lottery. The daily lotteries are as follows: About a 1 in 4 chance of winning $5. Expected value is about $1.40 per person per day. | Behavioral: Basic Lottery<br>* Participants who meet their daily step goals will be eligible for a daily lottery. They will have about a 1 in 4 chance of winning $5. Expected value is about $1.40 per person per day.<br>|
| Experimental: Combined Lottery<br>Participants receive either an email or text message daily (based on the participant's preference) stating whether the participant achieved the 7000 step goal during the previous day. Each day a lottery will be held, and participants will be eligible to collect monetary rewards only if the participant met the step goal the day before. The names of the winners will be announced during each lottery. The daily lotteries are as follows: About a 1 in 5 chance of winning $5 and a 1 in 100 chance of winning $50. Expected value is about $1.40 per person per day. | Behavioral: Combined Lottery<br>* Participants who meet their daily step goals will be eligible for a daily lottery. They will have about a 1 in 4 chance of winning $5 and a 1 in 100 chance of winning $50. Expected value is about $1.40 per person per day.<br>|
| Experimental: Jackpot Lottery<br>Participants receive either an email or text message daily (based on the participant's preference) stating whether the participant achieved the 7000 step goal during the previous day. Each day a lottery will be held, and participants will be eligible to collect monetary rewards only if the participant met the step goal the day before. The names of the winners will be announced during each lottery. The daily lotteries are as follows: About a 1 in 400 chance of winning $500. Expected value is about $1.40 per person per day. | Behavioral: Jackpot Lottery<br>* Participants who meet their daily step goals will be eligible for a daily lottery. They will have about a 1 in 400 chance of winning $500. Expected value is about $1.40 per person per day.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of Days a Minimum Activity of 7000 Steps or More is Achieved During Intervention | Our primary outcome measure is the proportion of days a minimum activity of 7000 steps or more is achieved. We will assess outcomes for 3 months using incentives followed by 3 months of follow-up without incentives. All available data will be analyzed, and missing will be treated as true missing data points. Secondary outcomes will include the average steps walked per day. | End of study- 6 months of after enrollment | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average Number of Steps Per Day During Intervention | Secondary outcomes include average number of steps per day during intervention (with incentives) and follow up periods (without incentives). | End of study- 6 months after enrollment |
