This study tested the risk principle with 400 New York City drug-court participants, using demographic data and data on criminal history, instant case, treatment modality, program failure, and rearrest.
Actuarial risk scores were created for program failure and re-arrest by performing stepwise logistic regressions based on criminal history, present case, and demographic predictors of these outcomes. Placement in a residential (vs. outpatient) setting increased the likelihood of program failure and re-arrest after controlling for actuarial risk scores. Residential placement was particularly counter-productive with low-risk program participants, whose re-arrest rate was more than double that of low-risk participants placed in an outpatient setting. Conversely, placement of low-risk participants in the least restrictive treatment modalitya non-intensive outpatient settinglowered the likelihood of re-arrest relative to placement either in a residential setting or an intensive outpatient program. Results are discussed in terms of the Risk-need-responsivity model of offender intervention, which recommends avoiding overly restrictive treatment of low-risk offenders. 26 references (Publisher abstract modified)
