A Multisite Randomized Block Experiment on the Seamless System of Care Model for Drug-Involved Probationers

Abstract

This multisite randomized block experiment examines the efficacy of the seamless system of care for probationers (an integrated probation model combined with substance abuse treatment intervention onsite at a probation office). The sample consists of 251 drug-involved probationers randomized into probation with referral to community treatment or the seamless system of care. Key outcomes are examined over a 1-year period by recidivism risk level. When compared with probationers in the control group, the findings are that those in the seamless system of care group had fewer drug use days overall, less alcohol consumption, improved treatment initiation and adherence, but a higher number of days incarcerated. Low-risk seamless system participants had the most favorable outcomes compared with other study conditions. This study demonstrates the importance of tailoring interventions to the risk level of the probationer, and that the seamless system works better for lower risk offenders with substance use disorders.
