PURPOSE OF REVIEW: A systematic review was conducted of family-based interventions to improve glycemic control, adherence, and psychosocial outcomes in children and adolescents with type 1 diabetes (T1D). Electronic databases were searched for randomized controlled trials (RCTs) published since the seminal Diabetes Control and Compliance Trial (DCCT). Interventions are summarized and findings reviewed to help guide clinical practice and future research. RECENT FINDINGS: Twenty-five RCTs are reviewed. The majority of studies (n = 15) focused on interventions targeting both children and adolescents and their caregivers and were delivered in diabetes clinics, outpatient settings, mental health clinics, or participants' homes. Family-based interventions for youth with T1D appear effective at improving diabetes and family-centered outcomes. Additional research is needed to examine the pathways to improvement in glycemic control, as outcomes were mixed. Future research should also involve measures beyond HbA1c given new markers for sustained health improvement and outcomes are being explored.
