Adolescent amphetamine users in treatment: client profiles and treatment outcomes.

This study compares client profiles of adolescent amphetamine users to those of nonusers and examines the multivariate prediction of posttreatment drug use, criminal, and HIV risk behavior outcomes in the year following their separation from treatment. Data were collected as part of a larger longitudinal study on a sample of 938 adolescents who were admitted to residential therapeutic community drug treatment programs across the eastern United States and Canada from April of 1992 through April of 1994. A subsample of 485 adolescents were reinterviewed one year after their separation from treatment. Findings indicated that amphetamine users tended to be white, older, and have parents with higher education and occupational levels than nonusers. However, they also had more psychopathology, more extensive drug use and criminal histories, and engaged in more HIV-risk behaviors than nonusers. Additionally, amphetamine users tend to come from homes where one or both parents used illicit drugs, drank regularly, or had a mental illness, and they often reported histories of childhood maltreatment. Analyses of the one-year follow-up data indicated that being an amphetamine user was not related to treatment outcome after the client's demographic characteristics, overall drug use severity, and treatment completion were taken into account. Therefore, therapeutic community treatment appears to be an effective means of treating adolescent amphetamine users.
