A descriptive evaluation methodology, dated June 1992, was prepared by the evaluation team and adapted to the unique characteristics of each program. New data were collected and analyzed when possible; existing data were assessed; and project staff and community stakeholders were interviewed for their perceptions of program strengths and weaknesses. The evaluation framework provided for the review of five basic aspects of program performance: program design, program management, service area coverage accountability, service delivery accountability, and program outcomes. The latter measure of program performance attempted to identify and measure reasonable indicators of program impact on treatment compliance and future behavior of the target populations. This report presents findings in each of these areas. Data on program outcomes focus on respondent perceptions of success, treatment completion rates, juvenile program completion rates, adult program completion rates, posttreatment arrest histories, and posttreatment arrests by completion status, as well as juvenile posttreatment arrest histories. The individual treatment programs reviewed varied greatly in the posttreatment arrest experiences of their clients; however, one clear pattern that emerged was that juvenile programs had higher posttreatment arrest rates than adult programs. 16 figures
