Lottery Incentives for Moving
A study testing Incentive to exercise in people with Obesity and Sedentary Lifestyle, run by Harvard University at 1 site in United States.
Trial summary
The purpose of the study is to learn more about effective ways to motivate people to increase their non-exercise energy expenditure exercise. This is an important research question because obesity and weight-related issues are increasingly becoming a problem in America. Read more about this study

About this study
The purpose of the study is to learn more about effective ways to motivate people to increase their non-exercise energy expenditure exercise. This is an important research question because obesity and weight-related issues are increasingly becoming a problem in America. This project will address this research question by testing the effect of two different incentive schemes in motivating employees who are predominantly sedentary to use Walkstations at work. The Walkstations are treadmills that move at a very slow rate (maximum 2miles / hour) and are attached to a work station (i.e. with computer and telephone); they therefore are designed to increase energy spent not through heavy exercise, but through small changes in posture and movement associated with routines in daily life (called nonexercise activity thermogenesis or NEAT).
Subjects will be employees of Blue Cross Blue Shield of Massachusetts (BCBSMA). Subjects will be the control participants from the previous Walkstation study we ran with BCBSMA. All 120 control participants from this previous study will be told that they can now participate in a study that involves the Walkstations (up until now, they have not been given access to the Walkstations). These participants from the previous study will be sent an email informing them that they are eligible to participate in this new Walkstation pilot. Those who are interested in participating will then be invited to sign up for an enrollment session. There will be no incentives for participating in the initial enrollment session. For the 2 month follow-up session, participants will have a chance to win 1 of 3 prizes (1 * $100, 2 * $50) for completing the follow-up.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Incentive to exerciseBehavioural
Participants who attain their walkstation goal will be entered into a draw every two weeks. We are testing the effect of different prizes on walkstation usage.
| Study group | Role | What they receive |
|---|---|---|
| Personal incentive | Active comparator | If participants attain their walkstation usage goal, they are entered into bi-weekly lotteries to win money. Receives: Behavioral: Incentive to exercise |
| Token incentive | Active comparator | Participants who attain their walkstation usage goal will be entered into a bi-weekly prize to win a token reward. Receives: Behavioral: Incentive to exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Walkstation usage
Measured: after approx 60 days
Secondary outcomes (2)
Biometric measures
Height, weight, blood pressure
Measured: baseline and 60 days
Questionnaire
Measured: baseline and 45 days
