Incentive-based physical activity program
"Drivers will be offered rewards valued at a day's rental for meeting daily step targets over the specified number of days each month from Months 1 to 4, where steps will be tracked by a step counter. They will also be offered incentives for meeting the following criteria:~1. Accurately predicting step target attainment the following months (SGD10)~2. Wearing and providing step data over the month (SGD10 and a chance to win 1 of 3 cash prizes valued at SGD500)"
3-month follow up
After the 4-month RCT, drivers will be incentivized to wear the step counter for another 3 months (i.e. Months 5 to 7) to test if effects of the rewards are sustained once the reward is no longer in place. For wearing their step counter and providing their step data, drivers will receive a modest cash incentive (amounting to SGD10) each month as well as the chance to win 1 of 3 cash prizes valued at SGD500.
