DIAMANTE Trial Design

3Treatment groups
Experimental Treatment
Active Control
Group I: Adaptive MessagingExperimental Treatment1 Intervention
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.
Group II: Static MessagingActive Control1 Intervention
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.
Group III: Control ConditionActive Control1 Intervention
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.
