Background: Social comparison feedback is often used in physical activity interventions but the optimal design of feedback is unknown.
Methods: This 4-arm, randomized trial consisted of a 13-week intervention period and 13-week follow-up period. During the intervention, 4-person teams were entered into a weekly lottery valued at about $1.
Article Synopsis
- A study aimed to see if lottery-based financial incentives could boost physical activity among University of Pennsylvania employees with a higher body mass index.
- 209 participants were monitored for 26 weeks, using smartphones to track their steps, with some receiving various types of incentives over half the study period.
- Results showed the "combined lottery" group achieved their step goals more often than the control group, while the "jackpot" group saw a drop in performance, indicating that the combined lottery incentives were the most effective in promoting activity.
Purpose: To compare the effectiveness of different combinations of social comparison feedback and financial incentives to increase physical activity.
Design: Randomized trial (Clinicaltrials.gov number, NCT02030080).
Background: More than half of adults in the United States do not attain the minimum recommended level of physical activity to achieve health benefits. The optimal design of financial incentives to promote physical activity is unknown.
Objective: To compare the effectiveness of individual versus team-based financial incentives to increase physical activity.
Background: Financial incentive designs to increase physical activity have not been well-examined.
Objective: To test the effectiveness of 3 methods to frame financial incentives to increase physical activity among overweight and obese adults.
Design: Randomized, controlled trial.
Study Objectives: We tested whether providing adults with obstructive sleep apnea (OSA) with daily Web-based access to their positive airway pressure (PAP) usage over 3 mo with or without a financial incentive in the first week improves adherence and functional outcomes.
Setting: Academic- and community-based sleep centers.
Participants: One hundred thirty-eight adults with newly diagnosed OSA starting PAP treatment.
