This study aims to examine the effects on diabetes self-management, health fatalism and metabolic parameters of individuals with type 2 diabetes. The study will be conducted in a health institution between February 2025 and May 2025 and participants will be assigned to experimental and control groups by simple random sampling method. The experimental group will be trained with motivational interviewing techniques based on the health belief model for 8 weeks, followed by sending reminder SMS for 4 weeks. The control group will receive no intervention. The study is expected to improve the self-care behaviors of individuals with diabetes by creating positive effects on diabetes management and health fatalism.

This study aims to determine the effect of education given with motivational interviewing technique structured according to the health belief model on diabetes self-management, health fatalism and metabolic parameters in individuals with type 2 diabetes. The research will be conducted in a pre-test and post-test randomized controlled experimental design.The population of the study will consist of individuals with type 2 diabetes who are registered in a health institution between February 2025 and May 2025 and who meet the research criteria. The sample determined by power analysis will consist of a total of 66 patients, 33 in the experimental group and 33 in the control group. Patient Introduction Form, Type 2 DM Self-Management Scale (SMS) and Health Fatalism Scale will be used to collect data from the experimental and control groups for pre-test and post-test. Weight, height, waist circumference and body mass index of the individuals will be measured by the researcher and HbA1c values of the last one month will be recorded. The experimental group will be given diabetes education with motivational interviewing technique structured according to the health belief model in line with the literature.Brochures and powerpoint presentations will be prepared as training materials. Trainings will be held in the training room on the days and times determined with the patients in 8 sessions lasting 30-40 minutes. At the end of the training, an SMS message will be sent once a week for four weeks. At the end of each visit, the next visit will be scheduled. Trainings will be conducted face-to-face by the researcher. The control group will not receive any training. After the completion of the trainings, a post-test will be administered to both the experimental and control groups. In the evaluation of the data; numbers, percentages, standard deviation, mean, minimum and maximum values, Chi-square, Fisher-Freeman-Halton Exact Test, Paired Samples t-test and Independent Samples t-test will be used.
