Finding effective treatment models for youth in the juvenile justice system with serious emotional, mental health, and behavioral needs can be difficult. The traditional categorical approach that the juvenile justice, child welfare, and mental health systems often use places youth in a "one-size-fits-all" program, regardless of the youth's needs. Wraparound Milwaukee takes a quite different approach. This approach, which is based on the Wraparound philosophy, offers care that is tailored to each youth. The following elements of the Wraparound approach have been found to be of particular importance when working with children in the juvenile justice system: a strength-based approach to children and families; family involvement in the treatment process; needs-based service planning and delivery; individualized service plans; and an outcome-focused approach. This program, which began in 1994, is made up of the following components: care coordination; the Child and Family Team; a mobile crisis team; and a provider network. Because Wraparound Milwaukee blends system funds, it can provide a flexible and comprehensive array of services to delinquent youth and their families. While this program offers many formal services, informal services that the care coordinator and Child and Family Team identify through strengths assessment are often even more effective. Outcomes for youth participating in Wraparound Milwaukee have been encouraging. Data indicate that the program is achieving positive outcomes. The challenges and the future of this program are briefly discussed. (MKA)
