Summary

We conducted a 3-month RCT with 30 adolescents (aged 13-15 years) and their caregivers to evaluate the effectiveness of the novel mHealth app "CommitFit", which uses gamification to motivate users to log and achieve health behavior goals. The RCT had three arms: (1) CommitFit only users, (2) CommitFit$, adolescents were paid $0.05 for each point they earned, and (3) Control. Software analytics, surveys, BMI, and blood pressure were evaluated at baseline, 3 months, and 4 months.

Detailed description

We will recruit 30 adolescents and 30 caregivers to beta test CommitFit. The study will be limited to one participating adolescent and one of their caregivers. There will be three groups in the study: 1) Control 2) CommitFit and 3) CommitFit$. All participants will be required to complete a screening survey at the beginning of the study. The eligible participants will be contacted via email/ phone and will give their consent after taking the screening survey, and then they will take the baseline demographic survey for their adolescents and themselves. After the participants in the CommitFit and CommitFit$ groups download the app, they will be shown how to pick a health behavior (fruits/vegetables, water, decreased sugary beverages, physical activity, sleep) and then set a goal and a time period to work on their goal. They will receive a daily reminder to log their health behaviors. At the end of their goal period, they will be rewarded with points for logging behaviors and successfully achieving their goals. Points will be used to rank the participant on the leaderboard using the username that they registered with. Users can also use points to unlock gear for their avatar in the gear store. Control group participants will receive email handouts with healthy lifestyle tips which they could use if they choose to. They will not use the CommitFit app. All participants will be compensated through eGift cards. Software analytics will be utilized to evaluate how the app was used (frequency of goals set and behaviors logged), duration of use, etc., to evaluate app features and gamification techniques. We will evaluate changes in health behaviors using online surveys, and measure health metrics (height and weight which will be used to calculate Body Mass Index (BMI), and blood pressure) in the clinic. We will have the adolescents take 7 surveys-GAD7, PedQL, Reasons why I think about being healthy, Behavior economics survey, Gamification Survey, CommitFit App Survey, and Commercialization Survey (CommitFit and CommitFit$ only for use surveys). Similarly, we will have the caregivers take 4 surveys Gamification Survey, CommitFit App Survey, Behavior economics survey, and Commercialization Survey for caregiver subject. In the control group, adolescents will only take 4 surveys- GAD7, PedQL, Reasons why I think about being healthy, and Behavior economics survey. Caregivers in the control group will take only the Behavioral Economic survey. All participants will take the surveys at the beginning of the study, after end of 3rd month, and at the end of the 4th month (follow-up visit). Weight, height and blood pressure from all adolescents and their caregivers will also be collected at the clinical site. All participants completed the 5-10 minute paper exit survey and interview at their final 4-month clinic visit.

Interventions

Type	Name	Description
OTHER	gamified mHealth lifestyle app	The CommitFit mHealth app uses gamification techniques to motivate adolescents and caregivers to set and achieve health behavior goals (eat more fruits or vegetables, increase water intake, decrease sugary beverage intake, increase physical activity, or increase overnight sleep). Users are ranked on leaderboard based on their points and can team up with caregivers on a team leaderboard.
OTHER	Attention Control	Standard of care healthy lifestyle handouts were emailed monthly to control families.
OTHER	gamified mHealth app with financial incentives	The CommitFit mHealth app uses gamification techniques to motivate adolescents and caregivers to set and achieve health behavior goals (eat more fruits or vegetables, increase water intake, decrease sugary beverage intake, increase physical activity, or increase overnight sleep). Users are ranked on leaderboard based on their points and can team up with caregivers on a team leaderboard. CommitFit$ adolescents received an extra $0.05 for each point they earned in the app.
