This study aims to generate knowledge needed to address seemingly intractable urban service delivery challenges: 1) lack of engagement of low-income youth with serious disruptive behavioral disorders and their families; 2) too few clinics offering family-based, evidence-informed services; 3) lack of scalable, empirically supported interventions designed for resource-strapped child settings and; 4) few empirically supported options for public policy makers to support the uptake and integration of service innovations in their systems.
