NCT ID: NCT02030080
Last Updated: 2017-12-29
Results Overview
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.

Feedback 50th Percentile
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.
Teams
Daily Feedback: Participants will be given daily feedback on whether or not they walked 7000 steps or more the day before.

Feedback 75th Percentile
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.

Feedback 50th Percentile + Lottery
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.

PRIMARY outcome
Timeframe: Throughout 6-month studyThe 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.
