Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
What will happen in the study? - 250 adults with type 2 diabetes from Xiang'an Hospital (Xiamen) will be randomly assigned to one of two groups:
Intervention group:Doctors will receive special training in "linguistic nudging" techniques to encourage shared decision-making. Patients will use a mobile app to record medication preferences, and doctors will adjust advice based on these preferences.
Control group:Patients will receive standard diabetes care without these additional strategies.
\- All participants will be followed for 6 months.
What is the study aiming to find out?
The main goal is to see if patients in the intervention group:
Better follow medication plans Improve blood sugar monitoring Have better blood sugar control Feel more satisfied with doctor-patient communication
Why is this important? Good self-management is key to controlling diabetes, but many patients struggle with it. Effective communication during shared decision-making may empower patients to manage their condition day-to-day with greater confidence.
Patient safety and rights:
Participation is completely voluntary All personal information will be kept strictly confidential Medical support will be provided if any health problems occur during the study Participants may withdraw at any time
This research has been approved by the Ethics Committee of Xiang'an Hospital (Approval date: October 2025).
