Outcome Measures

Primary Outcomes (1)

  • Glycemic control, assessed by hemoglobin A1c

    Every 3 months

Secondary Outcomes (3)

  • Psychosocial factors (diabetes-specific family conflict, responsibility-sharing for diabetes management tasks, quality of life, affect regarding blood glucose monitoring, disordered eating behaviors)

    Annually

  • Weight, assessed by z-BMI (age- and gender-adjusted body mass index)

    Every 3 months

  • Frequency of hospitalizations, emergency department visits, and episodes of severe hypoglycemia

    Every 3 months

Study Arms (3)

Standard Care

NO INTERVENTION

* Routine diabetes support and education from diabetes health care team * Assistance from a non-medical case manager (Care Ambassador) to schedule appointments, provide reminders about appointments, and help families contact health care providers about questions or concerns

Care Plus

EXPERIMENTAL

* Routine diabetes support and education from diabetes health care team * Assistance from a non-medical case manager (Care Ambassador) to schedule appointments, provide reminders about appointments, and help families contact health care providers about questions or concerns

Behavioral: Care Ambassador Intervention

Care Ultra

Behavioral: Care Ambassador InterventionBehavioral: Psychoeducational Intervention

Interventions

Care Ambassador provides additional monthly outreach (by phone or e-mail) to families between clinic visits.

Care PlusCare Ultra

A psychoeducational intervention module is reviewed with the family by the Care Ambassador at each clinic visit. The intervention focuses on incorporating intensive therapy into the daily routine of the child through positive family support for blood glucose monitoring and healthy eating. The intervention modules review positive family communication, realistic expectations, ways to avoid perfectionism and maintain family involvement, prevention of hypoglycemia, avoidance of diabetes-specific family conflict, and approaches to reducing "diabetes burnout".
