ABSTRACT
Until fairly recently, evaluations of multi-site substance abuse treatment programs based their conclusions on the predictors of program outcomes using data aggregated across units of treatment delivery. Little attention has been paid in the prior research to more systematically separate the effects of individual characteristics and treatment environment on treatment outcomes. This study investigates whether there are differences between sites in treatment effectiveness after controlling for differences in individual characteristics of participants. Effectiveness is measured by post-release arrests and detected drug use three years after release. The present study uses data from the TRIADD Drug Treatment Evaluation Project, a comprehensive evaluation of the Drug Abuse Program (DAP) delivered in 20 sites within the Federal Bureau of Prisons. The sample contains approximately 950 subjects who participated in drug treatment at low, minimum, and medium security level institutions from 1992-1997. Predictors include individual characteristics (eg., demographics, substance use history, psychiatric diagnoses, program completion status, and aftercare services received). In order to test for variations in treatment outcomes by institution, we use event history allowing for random effects.
