Brief Summary

To use a randomized controlled trial to test the effectiveness of four goal-setting strategies within a gamification intervention to increase physical activity among adults at elevated risk for ASCVD.

Detailed Description

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality in the United States. While increased physical activity can reduce this risk, less than half of adults in the United States meet the minimum recommendation guidelines for physical activity. Gamification, or the application of game design elements to non-game settings, has demonstrated promise in increasing physical activity when designed using insights from behavioral economics. However, the best way to design goal-setting within these interventions has not been well-examined. In this randomized controlled trial, the investigators will evaluate the effectiveness of four different goal-setting strategies within a gamification intervention to increase physical activity among adults with elevated risk for ASCVD. The trial will include a 2-week run-in period to estimate a baseline, followed by an 8-week introductory phase, an 8-week maintenance phase, and then after the intervention is completed an 8-week follow-up period.

Arm && Interventions

Group	Intervention	Description
Control	Daily performance feedback	Participants receive a daily message with their step count on the prior day to serve as an active control for 24 weeks (daily performance feedback). No other interventions during the 24-week study
Choice + Immediate	Daily performance feedback	Participants choose a step goal between 1000-3000 steps greater than their baseline (choice). They are asked to reach their full step goal upon intervention start (immediate). They will be in a gamification intervention for the first 16 weeks and then receive only daily feedback during the 8-week follow-up
Assigned + Immediate	Gamification	Participants in this arm will be assigned a step goal 2000 steps greater than their baseline (assigned). They will be asked to reach their full step goal as soon as the intervention begins (immediate). They will be in a gamification intervention for the first 16 weeks and then receive only daily feedback during the 8-week follow-up
Choice + Immediate	Choice + Immediate	Participants choose a step goal between 1000-3000 steps greater than their baseline (choice). They are asked to reach their full step goal upon intervention start (immediate). They will be in a gamification intervention for the first 16 weeks and then receive only daily feedback during the 8-week follow-up
Choice + Gradual	Gamification	Participants are asked to choose a step goal between 1000-3000 steps greater than their baseline (choice). They will be asked to increase their step goal by even increments of 12.5% each week for the 8 weeks of the ramp-up period (gradual). After the 8-week ramp-up period, they will be asked to maintain the step goal for the study. They may change their goal within the range at anytime. They will be in a gamification intervention for the first 16 weeks and then receive only daily feedback during the 8-week follow-up
Assigned + Gradual	Assigned + Gradual	Participants in this arm will be assigned a step goal 2000 steps greater than their baseline (assigned). They will be asked to achieve their step goal of 2000 steps incrementally over the 8 weeks of the ramp-up period (gradual). After the first 8 weeks, they will be asked to maintain their full step goal of 2000 for the the study. They will be in a gamification intervention for the first 16 weeks and then receive only daily feedback during the 8-week follow-up
