This document presents a review of recent research literature on eight components in a system of care for children with serious emotional disturbances. It is intended to be a guide and source of information to communities for building systems of care. Components include: residential services (psychiatric hospitals and residential treatment centers), outpatient services (psychotherapy), day treatment services, family preservation services, therapeutic foster care, crisis and emergency services, case management/individualized care, and family support services. The review of each component consists of definitions, summaries of outcome and empirically based efficacy studies, cost-effectiveness data, and (for most components) research needs. Generally, only studies published since 1988 were included. (Each chapter contains references.) (JDD)
