Participant Flow

After a participant consented to participating in the study, they are given a Fitbit device to wear for a 2 week run-in period to collect step and sleep data to estimate their 2-week baseline. Participants with a baseline above 7500 are excluded from the study due to them being too active.

240 participants were officially consented and enrolled per study design protocol. Out of 240, 137 are deemed ineligible due to high baseline (\>7500 steps) during the 2-week run-in or did not complete all recruitment steps before the study closed for enrollment. Out of 103 randomized, 9 from the intervention arm dropped before starting the study.

Participant milestones

Participant milestones
Measure
Control
Participants will receive a wearable device (e.g. FitBit) but no other interventions during the intervention or follow-up periods.Participants will also complete milestones within the study, such as the cognition and function assessment during weeks 1- 2, and 15-16. Participants will complete an end-of-study questionnaire on their experience with the wearable device and time in the study.
Gamification
Intervention participants will receive a wearable device (eg. FitBit) and enter a game designed with behavioral economics concepts over a 12-week intervention period. At the end of the 12 weeks, participants will enter a 6 week follow-up period where interventions will cease but passive step data collection will continue. Participants will complete milestones within the study: cognition and function assessment at weeks 1- 2, and 15-16. They will complete an end-of-study questionnaire on their experience with the wearable device and intervention design. Gamification: Each participant signs a pre-commitment contract agreeing to try their best to achieve their daily step goal. Each week over the 12 week intervention period, participants are endowed 70 points (10/day). Participants are told they will lose 10 points for each day the step goal is not met. Points are refreshed at the start of the week. At the end of the week, if the participant has 40 points or more, they will advance one level, or drop one level if they have less than 40 points. The levels include: blue (lowest), bronze, silver, gold, platinum (highest). Each participant begins in the middle (silver). Each participant will select a spouse, family member, or friend they see often to serve as supportive sponsor that receives a weekly email on participant progress including points, game level, and average step count. The supportive sponsor will enhance social incentives to motivate the participant towards their goal.

n=44 Participants
Intervention participants will receive a wearable device (eg. FitBit) and enter a game designed with behavioral economics concepts over a 12-week intervention period. At the end of the 12 weeks, participants will enter a 6 week follow-up period where interventions will cease but passive step data collection will continue. Participants will complete milestones within the study: cognition and function assessment at weeks 1- 2, and 15-16. They will complete an end-of-study questionnaire on their experience with the wearable device and intervention design. Gamification: Each participant signs a pre-commitment contract agreeing to try their best to achieve their daily step goal. Each week over the 12 week intervention period, participants are endowed 70 points (10/day). Participants are told they will lose 10 points for each day the step goal is not met. Points are refreshed at the start of the week. At the end of the week, if the participant has 40 points or more, they will advance one level, or drop one level if they have less than 40 points. The levels include: blue (lowest), bronze, silver, gold, platinum (highest). Each participant begins in the middle (silver). Each participant will select a spouse, family member, or friend they see often to serve as supportive sponsor that receives a weekly email on participant progress including points, game level, and average step count. The supportive sponsor will enhance social incentives to motivate the participant towards their goal.
