This paper discusses the results of a study that investigated the need for services across the continuum of child/adolescent mental health services in Virginia. Specific objectives of the study were to: (1) describe the youth receiving services; (2) determine where and to what extent gaps in services exist; (3) determine the reasons why youth do not receive services; (4) empirically classify youth on the basis of service packages received; and (5) identify those socio-demographic, clinical, and treatment history variables that best predict the service packages needed. Data were gathered through a survey of community-based case managers on a stratified random sample of youth who were receiving public mental health services (n=2,059). Results indicated the largest service gaps for youth with serious emotional disturbances (SED) were found for in-home supported living, day treatment, and residential support where less than 50 percent of recommended services were received. Several demographic and mental health variables can be used to predict which youth will be more likely to use a particular service package, including functioning level, history of mental health hospitalization, diagnosis, special education status, legal status, and residence.
