RT Article T1 Decide your time: a randomized trial of a drug testing and graduated sanctions program for probationers JF Criminology & public policy VO 15 IS 4 SP 1073 OP 1102 A1 O'Connell, Daniel J. A2 Brent, John J. A2 Visher, Christy A. LA English YR 2016 UL https://krimdok.uni-tuebingen.de/Record/1583728619 AB This study used a randomized controlled trial approach with a sample of 400 high‐risk probationers to test the hypothesis that a program incorporating principles of deterrence, graduated sanctions, and coerced abstinence would reduce recidivism rates among drug‐using offenders. Bivariate and multilevel modeling strategies were implemented. Findings revealed no discernable difference across multiple drug use, probationary, and recidivism measures between those randomized into the treatment condition and those receiving standard probation. In multivariate models, probationer age, employment status, and treatment participation improved some recidivism outcomes. Programmatic and sample characteristics are discussed regarding the lack of experimental effect.
