NCT01643538

Brief Summary

The goal of this randomized and controlled trial is to test whether a financial incentive of a donation to achieve a social goal is more effective to motivate and sustain a daily walking habit than the same dollar value given to an older adult. The investigators will achieve this using a novel computer platform utilizing a digital pedometer-internet interface.

Study Arms (4)

Control Arm

ACTIVE COMPARATOR

Daily use of pedometer for 5 months. Walking goal set based on level of walking during 2-week run-in period. Weekly feedback provided on meeting walking goal - defined as achieving goal number of steps for 5 of 7 days per week. Subjects in the Control Group will only receive pedometers and weekly feedback on their performance through the same mechanisms and with the same frequency as participants in the other three study arms. There will be no financial incentives or charity donations in this group.

Behavioral: daily pedometer use and weekly feedback

Personal Financial Incentives Arm

EXPERIMENTAL

Daily use of pedometer for 5 months. Walking goal set based on level of walking during 2-week run-in period. Weekly feedback provided on meeting walking goal - defined as achieving goal number of steps for 5 of 7 days per week. Each week, if pedometer is used and walking goal is met for 5 out of 7 days, participant will receive $20. Financial incentive is terminated after 4 months. Daily use of pedometer continues for an additional 4 weeks.

Behavioral: Financial incentiveBehavioral: daily pedometer use and weekly feedback

Social Goals Arm

EXPERIMENTAL

Daily use of pedometer for 5 months. Walking goal set based on level of walking during 2-week run-in period. Weekly feedback provided on meeting walking goal - defined as achieving goal number of steps for 5 of 7 days per week. Each week participants will be asked to designate which charity should receive a donation if they meet or exceed their goal. If they meet the goal, they will be notified that a donation of $20 in their name has been sent to the charity. Charity donation is terminated after 4 months. Daily use of pedometer continues for an additional 4 weeks.

Combined Financial Incentives & Social Goals Arm

EXPERIMENTAL

Daily use of pedometer for 5 months. Walking goal set based on level of walking during 2-week run-in period. Weekly feedback provided on meeting walking goal - defined as achieving goal number of steps for 5 of 7 days per week. Each week, the participant will be asked to choose whether to keep, give, or split the reward, if they meet or exceed their goal. If they choose to send some of the money to charity, they will be asked to identify a charity to which they would like to donate the payment. If they meet their goal, they will receive money and/or be notified that a donation of the selected amount has been sent to the charity, depending on their selected preference. Incentives are terminated after 4 months. Daily use of pedometer continues for an additional 4 weeks.

Interventions

Participants will receive a direct financial incentive in the amount of $20 for each week when their daily pedometer step count equals or exceeds their goal at least 5 out of 7 days.

Personal Financial Incentives Arm
Social GoalBEHAVIORAL

Participants will be asked to identify a charity to which they would like to donate the payment for reaching their walking goal. Each week they will be asked to designate which charity should receive a donation if they meet or exceed their goal. If they meet the goal, they will be notified that a donation of $20 in their name has been sent to the charity.

Social Goals Arm

Participants will be able to allocate their reward for reaching their walking goal: the $20 reward can be divided between personal financial incentive and a charitable donation. Each week, the participant will be asked to choose whether to keep, give, or split the reward, if they meet or exceed their goal. If they choose to send some of the money to charity, they will be asked to identify a charity to which they would like to donate the payment. If they meet their goal, they will be notified by email or mail (based on their preference), that a donation of the selected amount has been sent to the charity.

Combined Financial Incentives & Social Goals Arm

Daily use of pedometer for 5 months. Walking goal set based on level of walking during 2-week run-in period. Weekly feedback provided on meeting walking goal - defined as achieving goal number of steps for 5 of 7 days per week.
