This glossary contains terms frequently used when referring to the mental health needs of children and adolescents. The list is alphabetical. Words in italics are defined separately within the glossary. Since the words service and services are used frequently throughout the glossary, it may be helpful to begin by reading the definition for service. The terms in this glossary describe ideal services. These services may not be available in all communities. The Comprehensive Community Mental Health Services Program for Children and Their Families, administered by the Center for Mental Health Services (CMHS), has grantees in communities across the country that are demonstrating these services. For more information about children's mental health issues or services, call SAMHSA's National Mental Health Information Center at 1-800-789-2647.
