Type 1 diabetes is one of the most common pediatric chronic illnesses. Adolescents are at risk for poorer glycemic control; however, youth whose parents remain involved in diabetes care are in better control. The current study examined parental involvement (PI) using a multi-method, multi-source approach in a sample of 255 youth (Age M = 12.83). The Diabetes Family Responsibility Questionnaire, Parental Monitoring of Diabetes Care Scale, and 24-Hour Diabetes Interview assessed two types of PI, parental responsibility and parental monitoring. Global and specific assessment served to cross-corroborate indicators of PI related to HbA1c. Higher levels of monitoring related to lower HbA1c for both parent- and youth-report; however, the effect decreased after controlling for socioeconomic status (SES). Additionally, monitoring mediated the relation between age and HbA1c. Controlling for SES, youth whose parents demonstrated higher levels of monitoring were in better glycemic control. Both research and clinical implications are discussed
