This monograph explores the development of comprehensive systems of care for severely emotionally disturbed children and adolescents. It is intended as a technical assistance tool for states and communities interested in improving services and as a review of the state of the art for developing systems of care. A generic model of a system of care is presented, along with principles for service delivery and alternative system management approaches. The components of the system of care include mental health services, social services, educational services, health services, vocational services, recreational services, and operational services. Management of the system of care involves consideration of state-community relationships, alternative models for system management, and the role of case management and case review committees. Assessment of the characteristics of an effective system is also featured, and worksheets to assess the status of the system of care are provided. References accompany each chapter. (JDD)
