简要总结

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.

详细描述

The objective of the study is to test whether social incentives that encourage physical activity with another person are more effective than incentives for individual exercise. Physical inactivity and social isolation are growing epidemics linked to increased morbidity and mortality particularly among aging Americans. This research aims to address both problems by encouraging co-productive physical activities among college students. Co-productive physical activity mean anything involving physical activity that two people can do together, e.g., walking their dogs or shopping together. Additionally, in light of the COVID-19 pandemic, walking together in this study means either walking while communicating digitally or over the phone, or by physically walking together while wearing a mask, staying 6 feet apart, and following the recommendations from health professionals. A small randomized controlled trial will test the effectiveness of social incentives relative to traditional incentives in promoting walking behavior. Participants who are rewarded for walking together will be compared to those who are rewarded for walking even when alone. The results will indicate whether social incentives are more motivating than traditional incentives for walking behavior.

结局指标

主要结局

Mean Number of Days Met Daily Step Goal During Follow-up Period (Weeks 4-5) Minus Mean Number of Days Met Same Level of Walking in Baseline Period (Week 1)

时间窗: week 4-5

Mean number of days when an individual's number of steps walked was at or above daily goal during the follow-up period (weeks 4 \& 5) minus the mean number of days the individual's number of step's walking was at or above that same level during the baseline period (week 1)

Change in Score on University of California Los Angeles (UCLA) Loneliness Scale (Survey Measure)

时间窗: week 5

20-item scale measuring subjective feelings of loneliness and social isolation. Minimum score = 0; maximum score = 60; higher scores indicate more loneliness. We computed the difference in score from baseline (beginning of week 1) to end of study (end of week 5).

Change in Mean Daily Steps Walked From Baseline Period (Week 1) to Intervention Period (Weeks 2 and 3)

时间窗: week 2-3

Change in mean daily steps walked from baseline (week 1) to intervention period (weeks 2 and 3), as recorded on the FitBit app

Change in Mean Daily Steps Walked From Baseline Period (Week 1) to Follow-up Period (Weeks 4-5)

时间窗: week 4-5

Change in mean daily steps walked from baseline to follow-up period, as recorded on the FitBit app

Mean Number of Days Met Daily Step Goal During Intervention Period (Weeks 2-3) Minus Mean Number of Days Met Same Level of Walking in Baseline Period (Week 1)

时间窗: week 2-3

Mean number of days when an individual's number of steps walked was at or above daily goal during the intervention period (weeks 2 \& 3) minus the mean number of days the individual's number of step's walking was at or above that same level during the baseline period (week 1)

次要结局

  • Fraction of Days Participant Walked Together With Partner (Self Report) During Intervention Period (Weeks 2-3)(week 2-3)
  • Proportion of Days Participant Walked Together With Partner (Coded)(week 4-5)
  • Fraction of Days Participant Walked Together With Partner (Self Report) During Follow-up Period (Weeks 4-5)(week 4-5)
