Trial Title: Use of Continuous Glucose Sensors by Adolescents With Inadequate Diabetic Control

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: HEALTH_SERVICES_RESEARCH
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 3.0

Eligibility Criteria:
Inclusion Criteria:~1. Age of adolescent \> 11 years and \< 17 years. This age range was chosen because families of adolescents often struggle with diabetes management. Youths \> 18 years old may be likely to leave home during the study.~2. Diagnosis of type 1 diabetes based on the clinician's best judgment regarding the adolescent's proper diagnostic category.~3. Duration of type 1 diabetes \> 2 years or \> 1 year with negligible stimulated c-peptide level, to exclude those with significant residual pancreatic insulin production.~4. Treatment of diabetes for the 6 months prior to enrollment must consist of an intensified regimen including either daily use of an insulin pump or 3 or more daily insulin injections with pre-meal insulin doses calculated using a correction factor that considers prevailing blood glucose levels and planned carbohydrate intake.~5. Adolescent must have established diabetes care at a participating Nemours Children's Clinic site as evidenced by at least two diabetes clinic visits within the prior 12 months.~6. Most recent HbA1C \> 7.5% and \< 10.0% or mean HbA1C over the prior 12 months within that same range.~7. Intention to remain in the same region and to maintain diabetes care at the enrolling center for 12 months.~8. Family has working telephone service.~Exclusion Criteria:~1. Youth has not used a CGM device with real-time glucose feedback for clinical management of diabetes within the prior 6 months. Intermittent or one-time use of blinded CGM devices for retrospective analysis only is permissible.~2. Absence of any other medical conditions that, in the opinion of the attending endocrinologist, would impede completion of the study protocol.~3. Youths may not be on daily glucocorticoid medications due to hyperglycemic effects of these agents.~4. Not enrolled in special education for mental retardation, autism or severe behavior disorders.~5. Child not in an inpatient psychiatric unit or day treatment program during the 6 months prior to enrollment.~6. Primary diabetes caregiver not diagnosed or in treatment for major depression, psychosis, bipolar disorder or substance use disorder within the 6 months prior to enrollment; Child not in an inpatient psychiatric unit or day treatment program during the 6 months prior to enrollment.

Study Arms:
- Standard Care (Type: ACTIVE_COMPARATOR): Standard Care constitutes intensified diabetes management, an enrollment criterion for the study, consisting of either continuous subcutaneous insulin infusion (insulin pump) or multiple daily injections using a basal-bolus approach. All patients must be using carbohydrate counting and have prescribed correction factors for targeted insulin bolus dose adjustments.
- Continuous Glucose Sensor (Type: ACTIVE_COMPARATOR): Patients will have the same diabetes management regimen as those in the Standard Care group. In addition they will be given a continuous glucose sensor, receive expert instruction in its use, and be guided by a physician and diabetes educator in achieving glycemic benefits through retrospective and real-time interpretation of CGS results and by learning to respond judiciously to the various CGS alarms.
- CGS + Behavior Therapy (Type: EXPERIMENTAL): Patients in the use group will receive the same medical management as the Continuous Glucose Sensor group above. In addition, they will have 6 scheduled encounters with a behavior therapist that are designed to reduce or eliminate typical behavioral and/or psychological barriers to optimal use of CGS as part of diabetes care.

Based on this trial design, predict the completion outcome and termination type (if applicable).
