Type 2 diabetes is common in primary care, and daily self-care behaviors are essential for achieving blood sugar targets. This randomized, two-arm clinical trial will evaluate whether a structured narrative education program added to usual diabetes care improves glycemic control compared with usual care alone in adults with type 2 diabetes. Eligible participants (age ≥18 years) with suboptimal glycemic control (HbA1c ≥7.0% in the last 3 months) will be randomized 1:1 to either standard care or standard care plus narrative education. The narrative education program will be delivered by a family physician over 3 months and includes two individual face-to-face sessions (approximately 20-30 minutes) at Day 0 and Day 15 and four brief telephone reinforcement calls (approximately 3-5 minutes) on Days 30, 45, 60, and 75. The primary outcome is the absolute change in HbA1c from baseline (Day 0) to Day 90. Secondary outcomes include changes in diabetes self-care activities (SDSCA-TR), diabetes-related distress (PAID-5-TR), and body mass index (BMI) from Day 0 to Day 90.

This single-center, parallel-group randomized controlled trial will be conducted in a primary care family health center. After eligibility assessment and written informed consent, participants will be randomized 1:1 to the Narrative Education Group (intervention) or the Standard Care Group (control). Randomization will be generated by an independent third person not involved in the conduct of the study using computer-based block randomization (block size 4 or 6). Allocation concealment will be ensured using sequentially numbered, opaque, sealed envelopes opened in the presence of the participant after consent. Because of the nature of the intervention, participants and the clinician delivering the sessions cannot be blinded; however, data entry and statistical analyses will be performed using coded groups. Both groups will continue to receive routine diabetes management provided by the family physician and/or relevant specialists; the study protocol will not dictate medication initiation or changes. The control group will not receive any additional structured education sessions beyond routine counseling. Participants in the intervention group will receive a structured narrative education program over approximately 3 months, consisting of two individual face-to-face sessions (about 20-30 minutes) at Day 0 and Day 15 and four brief telephone reinforcement calls (about 3-5 minutes) at Days 30, 45, 60, and 75. Face-to-face sessions emphasize the patient's personal experience of living with diabetes using open-ended reflective questions, with the goal of increasing awareness, identifying barriers, and setting small, achievable behavior goals. Telephone calls are used for reinforcement and appointment reminders; no measurements or questionnaires are administered during these calls. Assessments will be performed at baseline (Day 0) and at 3 months (Day 90). At both time points, HbA1c and BMI will be recorded, and the SDSCA-TR and PAID-5-TR questionnaires will be administered. The primary outcome is the absolute change in HbA1c from Day 0 to Day 90. Secondary outcomes are changes in SDSCA-TR, PAID-5-TR, and BMI from Day 0 to Day 90. Process indicators (e.g., adherence to planned sessions and Day 90 follow-up rate) will also be reported.
