This clinical study aims to determine the effects of motivational interviewing and social media-based patient monitoring on metabolic control and self-efficacy in adolescents with Type 1 diabetes. Additionally, the study will assess the adolescents' attitudes toward their disease, quality of life, and perceived levels of social support. The primary research questions are as follows:

For adolescents with Type 1 diabetes who receive motivational interviewing and social media-based monitoring:

How do their attitudes toward their disease compare to those in the control group? How do their perceived levels of social support compare to those in the control group? How do their self-efficacy levels compare to those in the control group? How does their quality of life compare to that of the control group? How do their HbA1c levels compare to those in the control group?

One of the most common chronic diseases in adolescence is type 1 diabetes mellitus (T1DM). T1DM is one of the most common endocrine diseases of childhood and requires lifelong management. To minimize the impact of T1DM on adolescents, metabolic control should be ensured, self-efficacy should be gained, quality of life should be improved, and anxiety should be reduced.

Because the epidemiology, pathophysiology, developmental status, and response to diabetes treatment are different in adolescents than in adults with diabetes, the care of adolescents should be different from that of adults. This population should be managed by a multidisciplinary team trained in pediatric diabetes management and sensitive to the difficulties of adolescents with T1DM. The diabetes nurse in this team is responsible for providing diabetes self-management education and support, medical nutrition therapy, and psychosocial support during and regularly after diagnosis. Interventions should focus on empowering adolescents to better manage their disease. Educational programs should include approaches such as teaching specific diabetes management skills and developing independence in these tasks (e.g., carbohydrate counting, blood glucose monitoring) and promoting autonomy and motivation.

Motivational interviewing techniques can be used to elicit behavior change by helping patients identify and resolve ambivalent feelings. Motivational interviewing is defined as a collaborative approach that elicits intrinsic motivation and strengthens commitment to behavior change goals. Motivating patients makes them feel ready to change their behavior and ensures that interventions to improve diabetes management are effective. Recent studies have shown that motivational interviewing also has a positive impact on diabetes self-management.

Today, social media is a valuable tool for people with diabetes to improve their self-management skills. Lifestyle changes such as diet and exercise, blood glucose monitoring, online education, peer support, and real-time interaction between patients and healthcare professionals can all be facilitated through social media. Therefore, it is recommended that healthcare professionals use social media-based applications to improve diabetes self-management skills and thereby improve glycemic control. This study will determine the effect of motivational interviewing and social media-based patient monitoring on metabolic control and self-efficacy in adolescents with type 1 diabetes. It will also determine the attitudes of adolescents with T1DM toward their own disease, quality of life, and perceived level of social support.
