“…In contrast, research on programs and services for offenders is dominated by individual studies that present a collage of findings and only small glimmers of insight into the characteristics of effective programs. Examples include residential drug treatment programs (Hiller, Knight, Broome, & Simpson, 1998;Inciardi, 1999;Knight, Simpson, & Hiller, 1999;Martin, Butzin, Saum, & Inciardi, 1999;Pearson & Lipton, 1999;Simpson, Wexler, & Inciardi, 1999;Wexler & Melnick, 1999), drug courts (Belenko, 2002;Marlowe, DeMatteo, & Festinger, 2003;Marlowe, Festinger, Lee, Dugosh, & Benasutti, 2006;Taxman & Bouffard, 2002Wenzel, Longshore, Turner, & Ridgley, 2001), and community supervision (Taxman, 2002;Taxman & Thanner, 2006;Thanner & Taxman, 2003;Sherman et al, 1997). The collage is incomplete, and our knowledge of effective offender treatment, particularly in system-related issues, lags far behind the general treatment field (Farabee, Prendergast, & Anglin, 1998).…”
