Early studies of DWI Courts have shown successful results. Numerous individual courts have evaluated their program to find a significant reduction in recidivism.
Furthermore, a three-county evaluation in Michigan found that participants in DWI Courts were considerably less likely than DWI
offenders sentenced in a traditional court to be arrested for a new DWI offense or for any new criminal offense within 2 years of entering the programs.
The study was conducted by the Michigan State Court Administrative Office and data analyses were performed independently by NPC Research, Inc. The study examined outcomes for all participants who entered the programs, regardless of whether they graduated successfully, and drew on comparison offenders from the same counties who were matched on relevant eligibility criteria.
Some of the conclusions of the study were:
participants were re-arrested significantly less often than
comparison group offenders who were sentenced in a traditional
court. In an example from one DWI Court site, the comparison
offenders from a traditional court were re-arrested nearly six
times more often in the first year after starting probation for
the DWI charge than the DWI Court participants.
- In another example, in a 2-year period, traditional sentenced offenders in
the comparison group were more than three (3) times more likely
to be re-arrested for any charge and were nineteen (19) times
more likely to be re-arrested for a DWI charge than the DWI
- Participants in the DWI Court significantly decreased the percent of positive
drug tests over time. This provides support that the DWI Court was instrumental in reducing the amount of illegal drug use
during the first year participants spend in the program.
- Results show that DWI Court participants spent considerably more time in
treatment than those sentenced in a traditional court. Further, the average waiting period between arrest and sentencing was
significantly reduced in the DWI Court.
- The number of days spent in jail prior to program or probation start and the
total time in jail for that DWI case was also significantly reduced, thus saving the criminal justice system time and money.
- Time enrolled in the program was higher for DWI Court participants. Longer time spent in the program predicts success both in completing the program and in reducing recidivism.
