Background: Type 1 diabetes mellitus is the most common endocrine disease during infancy and adolescence. Diabetes causes serious coping problems during adolescence because of the need for continuous observation and because of diabetesrelated complications. Thus, adolescents must adapt to and effectively manage their diabetes. Purpose: This study was designed to determine the perceived barriers to home care in adolescentswith Type 1 diabetes using the Health Promotion Model. Methods: Eighteen adolescents were selected from the qualified patients who applied to a diabetes polyclinic at a training and research hospital in western Turkey. Interview questions were created based on the Health Promotion Model. A phenomenological analysis of the data was conducted using the content analysis method. Results: The barriers that participants identified as negatively impacting their ability to manage their disease effectively were categorized into the three themes of “negative feelings about having diabetes,”“personal barriers,” and “environmental barriers.” The barriers identified included school, friends, family, fear of complications, lack of information, and personal characteristics, among others. Conclusions/Implications for Practice: This qualitative study enables us to understandwhat patients feel because the participants explained their difficulties in managing their disease and inmaintainingmetabolic control. The findings provide an understanding of the subjective experiences of adolescent patients with diabetes. The findings of this study are intended to be helpful in restructuring training in clinics, raising diabetes awareness among teachers and students, socializing diabetic adolescents, and providing family-centered education.
