The current study reports the results of a pilot test of the Environmental Corrections model of probation and parole, a framework for supervising offenders in the community that focuses on opportunity-reduction strategies. A pilot test of Environmental Corrections was performed in one probation and parole office in a large metropolitan area of Australia. All staff in the office (n = 13) implemented the new model following training, and all offenders supervised at this office were subjected to the model (average daily caseload size, n = 450; total supervisees that took part in trial, n = 993). Trends and rates in official recidivism (new offences recorded by police) and breaches (technical violations of supervision conditions) were analysed at 6 months post-intervention using a statistically equivalent comparison group created through propensity score matching across 19 covariates associated with recidivism risk. Using the propensity score-matched control group, at 6 months post-intervention, 34.81% of the offenders in the control group had reoffended compared with 25.00% of the offenders in the matched treatment group (χ2 = 3.929, p < .05), for a reduction in the rate of reoffending of 28.18%. There were no statistically significant differences in rates of contravention between the two groups. The pilot test demonstrates that opportunity-reduction strategies hold promise for reducing recidivism among community-supervised offenders through the Environmental Corrections model, which incorporates case plan stipulations which knife-off crime opportunities, redesigns offenders’ routine activities, and utilises brief interventions focused on reducing situational propensity.
