Diabetes Disparities: Texting to Extend Treatment (DD-TXT)
Source: ClinicalTrials.gov · Last updated 26 Jun 2026
Brief summary (registry, in English)
One way to help Veterans improve their diabetes control is through the use of technology to help provide information, motivation, and reminders necessary to support diabetes self-management. The study will seek input from diverse groups of Veterans living with diabetes to help develop a new customizable, interactive texting intervention that allows Veterans to choose what kinds of diabetes self-management support they need, and when. This diabetes support will be provided to Veterans through "Annie for Veterans", a VA texting system for self-management support. Patients will be randomized to receive a once-daily standard diabetes self-management texting intervention called DSMS based on standard diabetes self-management education content or a customizable, patient-centered diabetes self-management support intervention with additional features called DSMS Plus (DSMS+) in order to test the comparative effectiveness of these two texting interventions.
