In 1984, the Federal Child and Adolescent Service System became the first to systematically address children’s mental health in collaboration with family members, advocates, policy makers, service and technical assistance providers, agency administrators, and cultural brokers. This group conceived the ”system of care” concept, which was defined two years later, and again in 2010: Updating the system of care concept and philosophy.

In 1992  the Comprehensive Community Mental Health Services for Children and Their Families Programbegan funding “systems of care” in states, communities, territories and tribal organizations. The aim was to galvanize collaborative, comprehensive ”systems,” including community-based organizations, to focus their support of young people’s recovery on resiliency and skills building through family-driven, youth-guided and culturally and linguistically competent services, supports, planning and treatment.

The Thrive Initiative (2005-2011) was Maine’s third System of Care grant from the federal Substance Abuse and Mental Health Services Administration (SAMHSA). As a result of Thrive’s work with Maine’s Office of Child and Family Services, all state contracted mental health agencies were required to be trauma-informed.

In October 2011 THRIVE became a non-profit entity. At the same time, Maine was one of 24 states, tribal communities and territories to receive a one-year SAMHSA expansion grant, under which three work groups overseen by a THRIVE-facilitated Statewide Leadership Team: developed continuous quality improvement standards for mental health agencies; planned for implementation of trauma-informed principles, practices and assessments in juvenile justice services; and developed and distributed a military family-driven mental health services satisfaction survey.

In October 2012 THRIVE became the training and technical assistance partner for Maine’s Department of Corrections Division of Juvenile Services’ four-year SAMHSA grant, Expanding Trauma-Informed System of Care Practices in Maine.
