An Adolescent Study Group was established by the Michigan Department of Public Health/Center for Substance Abuse Services (MCPH/CSAS) to examine the current delivery system of substance abuse treatment services for adolescents. The primary focus was on treatment services for alcohol, tobacco and other drug (ATOD) problems among adolescents in Michigan. The four charges of the group were to: (1) review CSAS current concept papers and other literature and develop a final position paper; (2) recommend how CSAS can assure that adolescents have access to and receive quality treatment services; (3) review current adolescent residential capacity in Michigan and make recommendations for improvement; and (4) provide input to CSAS regarding licensing requirements for adolescent treatment services. Subcommittees made 33 recommendations for improvement of service delivery. Some of the highlighted findings were: special attention to the treatment needs of homeless, runaway and school dropout adolescents is needed; the adult addiction model does not apply to most adolescents and should not be used in a clinical setting; and, adolescents indicated therapy groups should not be a mix of adolescents and adults. A glossary and extensive appendices are also included. Contains 43 references. (JBJ)
