The purpose of this article is to highlight the benefits of collaboration in child focused mental health services research. Three unique research projects are described. These projects address the mental health needs of vulnerable, urban, minority children and their families. In each one, service delivery was codesigned, interventions were co-delivered and a team of stakeholders collaboratively tested the impact of each one. The results indicate that the three interventions designed, delivered, and tested are associated with reductions in youth mental health symptoms. These interventions are feasible alternatives to traditional individualized outpatient treatment.
