“This study adds to the existing juvenile drug court literature by providing a national multi-site outcome and process evaluation of nine juvenile drug courts from across the U.S. This study assesses the relative effect of each court, as well as their combined effectiveness in reaching the overall goal of reducing recidivism and improving youths' social functioning. It also identifies, where possible, the characteristics of youth and programs associated with successful outcomes” (p. 6). Five sections follow an executive summary: research problem and study overview; background and literature review; research questions and objectives; results according to a sample description, site-by-site descriptives and results for nine juvenile drug courts, Evidence-Based Correctional Program Checklist – Drug Court (CPC-DC) results, and major outcomes; and summary and discussion. The drug courts did not reduce recidivism; in fact, they increased the level of risk that participants would experience new referrals and adjudication.
