No Intervention
Static Messaging
Adaptive Messaging
Control Condition
We will send patients a total of seven messages per week (one per day) at 10.00 am. For the physical health management messages we use messages from established topics in the Diabetes Prevention Program(23) content with the emphasis on physical activity and stress management. The final message, on the seventh day will ask patients to rate their mood on a scale from 1 to 9. Physical activity (step-count/day) will be passively monitored via the app on their smartphone.
Patients in the adaptive messaging arm will receive the daily messages of the static arm, and additionally receive daily messages within different categories of feedback and motivational messages that are chosen using a reinforcement learning (RL) algorithm. Physical activity (step-count/day) will be actively monitored via the app on their smartphone.
Control patients will only install the app on their phone and will not receive any feedback messages. They will receive one message a week, on a fixed day, asking them to assess their mood in the previous week on a scale of 1 to 9. The message will be sent daily at 10:00 am. Non-responders will receive reminders to submit their mood self-assessments in two hour intervals.
