Making Effective Use of State and Local Data Sources: Drug Court Evaluations in Michigan Gwen Marchand, NPC Research Shannon M. Carey, NPC Research Mark Waller, NPC Research David Crumpton, NPC Research Michael W. Finigan, NPC Research
Background • Outcome and Cost Evaluation for the State Court Administrative Office (SCAO) in Michigan • Focus on two local courts: • Barry County Drug Court • Kalamazoo Adult Drug Treatment Court
Guiding Questions • 3 key policy questions guiding evaluation: • Do drug treatment court programs reduce substance abuse? • Do drug treatment court programs reduce recidivism? • Do drug treatment court programs produce cost savings (in terms of avoided costs)?
Court Descriptions • Barry County • Court serves about 80 individuals annually • Overall graduation rate of 44% • Emphasis on OUIL (drunk driving) offenders • Kalamazoo County • Serves approximately 260 individuals annually • Gender specific services • Overall graduation rate of 37%
Evaluation Samples • Barry • Drug Court Group: • All participants from January 1, 2002 through July 1, 2004 • N = 87 • Comparison Group: • Chosen from eligible referred individuals who exceeded start-up capacity • Individuals arrested on DC eligible charges during study time period, but who did not go to DC • N = 148
Evaluation Samples • Kalamazoo • Drug Treatment Court Group: • Participants enrolling between January 2002 and December 2003 • Female N = 74 • Male N = 167 • Comparison Group: • Referrals who did not enroll in KADTC • Female N = 95 • Male N = 163
Data Collection Challenges • Location • Access • Format
Question 1: Do drug treatment court programs reduce substance abuse? Barry County: YES

Question 1: Do drug treatment court programs reduce substance abuse? Kalamazoo County: YES
Substance Abuse Reduction • Kalamazoo Points of Interest: • After first 2 months, graduates never exceeded 5% positive tests • When using probation data, comparison group maintained consistent level of positive tests (4-6%), whereas DTC participant positive tests declined • Comparison group higher drug-related arrests than • Male KADTC participants • Female KADTC participants
Question 2: Do drug treatment court programs reduce recidivism? Barry County: YES
Recidivism • Barry Points of Interest: • In 24 months following drug court entry… • 4% of graduates were re-arrested • 26% of all BCADC participants were re-arrested • 50% of comparison group were re-arrested • BCADC members had significantly fewer • Misdemeanor arrests • Felony arrests • Drug-related arrests

Question 3: Do drug treatment court programs produce cost savings? • Cost Elements: • Arrest • Jail and Booking • Probation days • Prison days • Subsequent court cases • Treatment • Victimizations • Jail Sanction Days
Question 3: Do drug treatment court programs produce cost savings? • Total Program Cost Savings (for outcomes over a 24-month period) $3000 x 108 = $353,160 Barry County: YES
Cost • Barry County Points of Interest: • Program Costs • $7,752/participant • Investment Costs • Drug Court = $3,109 • Comparison Group = $3,949 • Outcome Costs • Graduates = $1,385 • Drug Court total = $7,584 • Comparison Group = $10,854
Question 3: Do drug treatment court programs produce cost savings? • Total Program Cost Savings (for outcomes over a 24-month period) $442,520 + $150,634 = $593,154 Kalamazoo County: YES Women Men
Costs • Kalamazoo County Points of Interest: • Program Costs • Men = $5,767/participant • Women = $7,450/participant • Investment Costs • Men’s Drug Court = $3,134/Comp group = $3,360 • Female DC = $2,632/Comparison group = $4,979 • Outcome Costs • Male Drug Court = $21,969/Comp group = $22,871 • Female DC = $10,004/Comp group = $15,984
Final Points • These two programs were: • Beneficial to participants: Functioning member of society • Beneficial to taxpayers: Cost effective • A standardized methodology: • Should act as a guide for evaluation • Should be flexible • Should be rigorous
