Testing a Communication Strategy to Improve Shared Decision Making and Self-Management in Adults with Type 2 Diabetes

What this Trial Is About

Researchers are evaluating whether a communication method called linguistic nudging can help adults with type 2 diabetes make better treatment decisions together with their doctors. This study aims to see if this approach improves patients ability to manage their diabetes, including medication adherence, blood sugar monitoring, and satisfaction with doctor-patient communication. The trial includes 250 adults with type 2 diabetes and is supported by the Ethics Committee of Xiangan Hospital. Participants are randomly assigned to one of two groups an intervention group where doctors receive special training in linguistic nudging to encourage shared decision-making and patients use a mobile app to record medication preferences and a control group receiving standard diabetes care without these additional strategies. The doctors in the intervention group adjust their advice based on patient preferences recorded through the app. All participants are followed for 6 months. During the study, researchers will measure changes in blood sugar control using glycated hemoglobin HbA1c levels, assess diabetes self-management ability through a questionnaire at baseline, 3 months, and 6 months, and evaluate shared decision-making scores at the start. Personal information is kept confidential, safety is monitored, and participants may withdraw at any time. The study lasts 6 months from enrollment to final assessments.
