Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test the overall effects of incentives on physical activity among older taxi drivers, and whether mental accounting exists in this context.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

As part of the 4-month Randomized Controlled Trial, participating taxi drivers will be assigned to 1 of 2 groups where they will receive either cash or taxi rental credits for meeting specified monthly step goals measured via a step counter. Subsequently, for an additional 3 months, drivers will be incentivized to wear step counters to test if effects of the rewards are sustained once the reward is no longer in place. Effects will be quantified in terms of step activity; and in terms of changes in Body Mass Index (BMI), Resting Heart Rate (HR), Blood Pressure (BP), self-reported General Health, Health-Related Quality of Life (HR-QOL) and work productivity.

Outcome Assessors

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cash Only (CO)

As part of the Incentive-based physical activity program, drivers assigned to the Cash Only (CO) arm will earn incentives in the form of cash for meeting specified monthly step goals from Months 1 to 4.

Group Type EXPERIMENTAL

Incentive-based physical activity program

Intervention Type BEHAVIORAL

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

Intervention Type BEHAVIORAL

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.

Mental-Accounting (MA) based

As part of the Incentive-based physical activity program, drivers assigned to the Mental-Accounting (MA) based arm will receive incentives in the form of taxi rental credits for meeting specified monthly step goals from Months 1 to 4.

Group Type EXPERIMENTAL

Incentive-based physical activity program

Intervention Type BEHAVIORAL

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:

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

Intervention Type BEHAVIORAL

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.
