Evaluation of the South St. Louis Adult Drug Court:Process and Outcomes Jeff Maahs, PhD Katie Zafft, MA University of Minnesota Duluth Special thanks to Jared Hoy, Jane Greathouse, Jen Wright, Cheryl Harder, and Dennis Cummings.
Drug Court Basics • Collaborative Effort • Courts, Public Defenders, Prosecutors, Probation, Police, Local service providers... • Treatment orientation • Expect some failure early on (graduated sanctions) • Team supervision approach • Judge, prosecution, treatment staff are all involved in review of cases
The South St. Louis Drug Court • Inception in April of 2002 • The program takes all 3rd through 5th degree felony drug offenders, assuming other criteria are met • Primary exclusion criteria include non-residency and prior conviction for a violent crime. • Offenders get Rule 25 assessment, and appear in drug court as soon as possible • Drug treatment through outpatient and residential treatment through private vendors
The South St. Louis Drug Court(cont.) • Clients proceed through three phases • Restrictions, drug testing, supervision decreases at each phase • Phase four is graduation • Basic program elements • Probation supervision • Drug treatment and/or cognitive skills group treatment • UA • Court reviews
Study Background • Initial Process Evaluation completed in December, 2004 • Current Study Completed in November, 2007 • Update/reassess process related issues • Conduct outcome (recidivism) analysis with a comparison group • Both studies utilized data collected by ARC
Process Related Questions • Is the drug court enrolling appropriate clients? (Risk, Substance Abuse) • Are participants completing the program? (Retention rates, Graduation rates) • Are participants receiving the treatment and supervision outlined in the drug court protocol? • Does drug court have an impact on graduates? (Substance use, Risk for recidivism)
Who is in drug court? • Demographics • Risk for Recidivism • LSI • Criminal History • Substance Use • Arrest Data, LSI self-report data • LSI Alcohol/Drug problems scale • Not “A bunch of UMD students who got caught with mushrooms” • Medium risk group overall
Time Between Arrest and Drug Court Entry • Drug court rationale = get people involved in the program while they are still “shaken up” from arrest • Median time to from arrest to first drug court appearance = roughly 4 months • Hides many “quick” entries • Primary problem appears to be bail • Is speed really critical for effectiveness?
Level of Supervision • Urinalysis data • Probation Supervision • ROPE checks and cognitive skills sessions not “counted” in data • Court Reviews • Overall, supervision appears up to snuff
Treatment • Drug Treatment • Residential = 35%, Outpatient = 34% • Total Drug Treatment Rate = 65% • The role of Rule 25 assessment • Over 80% successfully complete treatment • Cognitive Skills program • 72% attended treatment • Overall (Cog skills + drug treatment) Treatment rate for grads = 95%
Intermediate Outcomes • Substance use • Average of over 370 days of clean UAs prior to graduation • Given that most had at least one dirty UA, this is a reduction in use • Recidivism Risk • LSI reassessment • Reduction in total LSI • Especially apparent in Alcohol/Drug Scale
The relationship between drug treatment and recidivism • Expectation is that those who complete treatment should be less likely to be convicted of a new offense • No clear pattern consistent with this expectation • Controlling for risk, treatment does not predict conviction for a new offense. • Different ways of controlling for risk, different measures of recidivism
Outcome Study • Quasi-experimental Design • Historical Comparison Group • Would have been eligible for drug court if drug court had existed • Arrested for 3rd through 5th degree felony drug offenses between 1999-2002 • Received probation • Recidivism • BCA checks backed up by CSTS checks • Any conviction, Felony conviction, Felony drug convictions • Conviction as a conservative measure of recidivism
How similar are the drug court and control groups? • Differences in prior record • Control group appears to be higher risk based on: • % Male, % Nonwhite • Prior adult convictions • Prior post-conviction incarceration • LSI data questions • Control group scores higher on criminal history, but lower on less “objective” measures • Reliability Issue We used most objective component of LSI (criminal history)
The Issue of Time at Risk • Control group arrested from 1999-2002 • More street time = more time for failure • One solution is “survival analysis” • Essentially, a moving (week to week, or month to month) recidivism rate • Each percentage based only on the people who are still eligible to offend • If someone is only at risk for the first three months, they are not used to calculate the recidivism rate for the fourth month • “SURVIVAL” rate = (1 - Recidivism Rate)
Must still “control” for differences in groups • Ran multiple “Cox regression” models, controlling for: • Age • Race • Sex • Education • Criminal History • Does group status (drug court versus control) predict survival? • Yes, when predicting felony conviction
Survival plot for felony convictions, controlling for demographics and criminal history
Ya see Timmy... • Solid Evidence that the South St. Louis Drug Court reduces the likelihood of recidivism • Drug Treatment • Why doesn’t successful drug treatment completion predict recidivism? • Review of drug treatment providers? • Process Related Issues • Overall, process measures are good • Keep moving towards higher risk clients • Increase the drug treatment rates • LSI quality control • Keep tracking the drug court cohort
