Adequate access to child and adolescent mental health services for young people in high need populations is an important concern of service systems researchers and program evaluators. We present results of a statewide study of access to community mental health services for eight populations of special concern. The analysis relied exclusively on existing databases in conjunction with innovative statistical techniques to provide comprehensive measures of access to care. Our findings indicate that access to care varied substantially across special populations, although children and adolescents in each of our eight “special populations” had greater access to public mental health services than members of the general population of the state. The interpretation of the findings and directions for future research are discussed.
