Effective communication between pediatric diabetes patients and their providers has the potential to enhance patient satisfaction and health outcomes, as well as improve diabetes-related self-management. In this review, we highlight the importance of communication between patients and providers, focusing on the effect of communication on adherence in the high-risk population of adolescents with type 1 diabetes. We synthesize the literature describing patient–provider communication in pediatric populations and provide implications for practice that focus on the most relevant, modifiable factors for improving self-management in adolescents with type 1 diabetes.
