Arms Assigned Interventions
Experimental: Teamwork Group
Families randomized to the Teamwork Group received the behavioral family teamwork intervention.
Behavioral: Family Teamwork Intervention

No Intervention: Standard Care
Families in the Standard Care group received standard diabetes care and equal attention from study staff between visits to schedule appointments and encourage regular diabetes follow-up care.
