Background: Studies have shown that adolescents find diabetes management difficult and struggle with incorporating diabetes management into their daily life. A focus on issues adolescents perceive as important is necessary when designing high quality interventions aimed at improving health outcomes for adolescents with T1D. The present study aimed to provide: (1) a broad comprehensive reflection on issues adolescents with diabetes perceive as important; (2) a basis for developing a ‘Family Mirror’, specifically designed to generate dialogue in families with an adolescent with T1D. Methods: The qualitative data originate from 11 workshops with a total of 47 adolescents with diabetes between 8 and 18 years of age. Data were systematically analyzed. Results: Seven overarching, empirical themes were identified that provided an outline of aspects important to adolescents living with T1D: (1) Support, (2) Understanding, (3) Worries, (4) Limitations, (5) Independence, (6) Perceptions, and (7) Management. Several empirical indicators elaborated on the themes, thus creating a comprehensive reflection of life with T1D during adolescence. Conclusion: Given our comprehensive and broad approach to uncovering key aspects adolescents with diabetes perceive as important, we trust that the findings can be used as a basis for designing interventions intended for adolescents with T1D.
