Provides an overview of the Northwestern Juvenile Project, the first large-scale, prospective longitudinal study of drug, alcohol, and psychiatric disorders in a diverse sample of juvenile detainees. This bulletin provides an overview of the project and presents information on its goals, sampling and interview methods, areas of measurement, and selected findings. The research found that the mental health needs of youth detained in the juvenile justice system are far greater than those in the general population, and that these needs are largely untreated. Among detainees with major psychiatric disorders and functional impairment, only 15 percent had been treated in the detention center before release. |
