ABSTRACT
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).SETTING:
Philadelphia, Pennsylvania.PARTICIPANTS:
Two hundred eighty-six adults.INTERVENTIONS:
Twenty-six weeks of weekly feedback on team performance compared to the 50th percentile (n = 100) or the 75th percentile (n = 64) and 13 weeks of weekly lottery-based financial incentive plus feedback on team performance compared to the 50th percentile (n = 80) or the 75th percentile (n = 44) followed by 13 weeks of only performance feedback.MEASURES:
Mean proportion of participant-days achieving the 7000-step goal during the 13-week intervention.ANALYSIS:
Generalized linear mixed models adjusting for repeated measures and clustering by team.RESULTS:
Compared to the 75th percentile without incentives during the intervention period, the mean proportion achieving the 7000-step goal was significantly greater for the 50th percentile with incentives group (0.45 vs 0.27, difference 0.18, 95% confidence interval [CI] 0.04 to 0.32; P = .012) but not for the 75th percentile with incentives group (0.38 vs 0.27, difference 0.11, 95% CI -0.05 to 0.27; P = .19) or the 50th percentile without incentives group (0.30 vs 0.27, difference 0.03, 95% CI -0.10 to 0.16; P = .67).CONCLUSION:
Social comparison to the 50th percentile with financial incentives was most effective for increasing physical activity.Palavras-chave
