结局指标
主要结局
Usability of the Application
时间窗: 4 weeks
Usability is defined via Young's Mobile Phone Usability Questionnaire (MPUQ) as how easy the app is to use and how easy it is to learn. The investigators will assess components of usability including: 1) learnability (how easy is it to accomplish basic tasks the first time the app is used?); 2) efficiency (once users can use the app, how quickly can they perform tasks?); 3) memorability (if a user returns to an app after not using it for some time, how easy is it to re-establish proficiency?); 4) errors (how many, how severe, how easy to recover?); and 5) satisfaction (how pleasant is it to use the app?).
Engagement with the Application
时间窗: 4 weeks
The quantitative assessment of the daily use of the mobile application, including the response to prompts, interactions with lifestyle coach, points earned, and tracking of weight, diet, and physical activity.
