There are State \u201csystems\u201d that provide standard guidelines to counties and local communities in the State, and there are numerous local county and community programs that appear promising in reducing DWI recidivism. The authors prepared case studies for two State programs (Nebraska and Wisconsin), four individual area ISPs (\u201cStaggered Sentencing for Multiple DWI Convicted Offenders\u201d in Minnesota; \u201cSerious Offender Program\u201d in Nevada; \u201cDWI Enforcement Program\u201d in New York; and \u201cDUII Intensive Supervision Program\u201d (DISP) in Oregon) and two rural programs (\u201c24/7 Sobriety Project\u201d in South Dakota; and \u201cDUI Supervised Probation Program\u201d in Wyoming). These ISPs revealed certain common features: 1. Screening and assessment of offenders for the extent of their alcohol/substance abuse problem; 2. Close monitoring and supervision of the offenders; 3. Encouragement by officials to complete the program requirements successfully; 4. Jail for noncompliance. The authors evaluated three of the programs. The Minnesota Staggered Sentencing Program appeared to be successful in reducing offender recidivism, even given the small sample size of program offenders (n=200). Compared to a similar matched group of DWI offenders, the staggered sentencing offenders had a significant 30.6% lower recidivism rate (p=.017) up to 4 years post-offense. The program prevented an estimated 15 to 23 re-arrests for DWI due to its effectiveness. The Westchester County program appeared to be effective in the short term (18.1% lower recidivism in 5 years post-offense [p.001). The program prevented 67 re-arrests for DWI in the first 8 years. The benefit/cost of ISPs appears to be very good for the prevention of rearrests. Preventing re-arrest for DWI for multiple offenders saves thousands of dollars in sanctions (jail time) and rehabilitation.129
