“…Despite considerable methodological and empirical developments in the economic assessment of adult substance abuse programs (Barnett, Zaric, & Brandeau, 2001;Cisler, Holder, Longabaugh, Stout, & Zweben, 1998;Daley, Argeriou, McCarty, Callahan, Shepard, & Williams, 2000;French, Salomè, Krupski, McKay, Donovan, McLellan, & Durell, 2000;French, Salome, Sindelar, & McLellan, 2002a;McCollister, French, Inciardi, Butzin, Martin, & Hooper, 2003), economic evaluation techniques have not yet been systematically adopted in studies of adolescent addiction treatment. The economic evaluation of adolescent addiction treatment is considerably more complex than that of adult treatment because of the diversity of juvenile delivery systems, the absence of standardized economic instrumentation or modules, the integral participation of parents/guardians and other family members, the unique social and economic outcomes, and outcome measures with highly skewed distributions.…”
