In this study, the comprehensive health service center will be considered the cluster and the unit of randomization. A multistage sampling method will be used. First, a list of all urban, rural, and urban–rural comprehensive health service centers in Khorramshahr will be prepared, and six centers will be selected using simple random sampling. These six centers (clusters) will then be randomly allocated by a statistician to either the intervention group (three centers) or the control group (three centers) using simple random allocation. After the allocation of clusters, the list of patients with type 2 diabetes covered by each center will be obtained and used as the sampling frame. From each center, 30 eligible participants will be selected using systematic random sampling. Additionally, a list of 30 replacement participants will be prepared to substitute individuals who do not meet the inclusion criteria or decline participation. All participants in centers allocated to the intervention group will receive the educational intervention, whereas participants in centers allocated to the control group will receive routine care provided by the health centers. In this design, all patients within each center will be assigned to the same study group according to the cluster allocation in order to prevent contamination between the intervention and control groups, Blinding description: This study is designed as a single‑blind trial. In this study, the data analyst will be blinded to the allocation of participants to the intervention and control groups as well as to the details of the intervention. Due to the educational nature of the intervention, blinding of participants is not feasible. N/A Diabetes. Intervention 1: Control group: Participants in the control group will receive only the routine health care services provided at the comprehensive health service centers during the study period. Intervention 2: Intervention group: In the intervention group, a blended educational program consisting of face‑to‑face and virtual education will be implemented. The face‑to‑face component will be conducted through lecture sessions accompanied by question‑and‑answer discussions, while the virtual component will include educational video clips, distribution of pamphlets, and motivational educational text messages sent to the participants’ mobile phones. The intervention is designed based on the Theory of Planned Behavior and will be delivered over four weeks, including two one‑hour face‑to‑face educational sessions and four virtual sessions during the same period. After obtaining informed consent from the participants, the questionnaires will be completed and fasting blood sugar (FBS) will be measured in both the intervention and control groups before the start of the intervention. In addition, three months after completion of the educational program, follow‑up will be conducted, the questionnaires will be completed again, and fasting blood sugar will be measured by taking blood samples from patients at the comprehensive health service centers.
