Impaired-driving recidivism among repeat offenders following an intensive court-based intervention.
PURPOSE: Repeat impaired-drivers resist successful rehabilitation. This paper describes and evaluates an innovative court-based intervention for repeat impaired-driving offenders, the driving under the influence (DUI) Intensive Supervision Program (DISP) developed in Multnomah County, Oregon. METHODS: The hazard of re-offending was compared between DISP participants (N=460) and a comparison group (N=497). The stratified Cox proportional hazards model was used to model the hazard of re-offense, adjusting for matching criteria and stratified by county of residence. RESULTS: Adjusted hazard of DUI re-offense for DISP participants was 0.52 that of comparison offenders (95% CI=0.36-0.76). DISP clients also had lower arrest rates for driving while revoked/suspended and for all other traffic offenses. CONCLUSION: Preliminary results suggest the DISP is an effective means of reducing recidivism among repeat impaired-driving offenders.
