Summary
A randomized controlled trial will test the effectiveness of social incentives relative to traditional incentives in promoting walking behavior among college students (N=200). Participants who are rewarded for walking together will be compared to those who are rewarded for walking even when alone. Research participants will download activity tracking apps (Fitbit app and AWARE app) that provide activity and location data. Participants will be consented and then randomized to one of two incentive schemes for walking. Over a 2-week intervention period, the standard incentive group will earn $2 per day when they meet their walking goal regardless of whether they walk alone or with others. The social incentive group will earn $1 per day when they reach their walking goal plus an additional $1 when they walk at least 2000 steps with their walking partner. The incentive scheme will be in place for 2-weeks, preceded by a 1-week baseline period and followed by a 2-week follow-up period.
