Brief Summary

Problems with diabetes management in adolescents with type 1 diabetes are common - occurring at rates as high as 93% - and have serious health consequences, including poor blood sugar control and risk for later complications. Therefore, the investigators proposed to test a positive psychology intervention for adolescents with type 1 diabetes aimed at increasing motivation for diabetes management; specifically, to increase the frequency of blood glucose monitoring. This intervention will boost positive mood in adolescents (age 13-17) through tailored exercises in gratitude, self-affirmation, small gifts, and parent affirmation as a way to improve motivation for diabetes management. In addition, this study will explore the use of technology, by comparing telephone-administered vs. automated text-messaging versions of the intervention, to determine which mode of delivery is more appealing, convenient, and beneficial for adolescents in managing their diabetes. Participants and parents will complete questionnaires on mood and diabetes management during a routine clinic visits at baseline, 3 months, and 6 months. Clinical measures of diabetes management will be collected from participants' electronic medical records.
