Based on research at the Oregon Social Learning Center, Multidimensional Treatment Foster Care (MTFC) targets children aged 3-18 who demonstrate chronic antisocial behavior, emotional disturbance and delinquency. Children are placed in a 'treatment foster family' where a positive, consistent and structured environment is provided to encourage pro-social and age-appropriate behavior. Young people aged 3-5years (MTFC-preschool), 6-11years (MTFC-latency) and 12-18 years (MTFC-adolescent) are referred to the program from youth justice, foster care and mental health agencies. Multidimensional Treatment Foster Care is a Blueprints Model Program.
