Official title

Improving Diabetes and Depression Self-management Via Adaptive Mobile Messaging

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The main aim of the "Diabetes and Mental Health Adaptive Notification Tracking and Evaluation" trial (DIAMANTE) is to test a smartphone intervention that generates adaptive messaging, learning from daily patient data to personalize the timing and type of text-messages. We will compare the adaptive content to 1. a static messaging intervention with health management and educational messages and 2. a control condition that receives a weekly mood message. The primary outcomes for this aim will be improvements in physical activity at 6-month follow-up defined by daily step counts.
