Alternative Sentencing Policies for Drug Offenders: Evaluating the Effectiveness of Kansas Senate Bill 123, 2001-2010 (ICPSR 30982)

Released/updated on: 2014-01-31
Geographic coverage: United States, Kansas
Time period: 2001-11-01--2010-08-31

The study examined the first five years of operation of Kansas senate bill 123 (November 2003-November 2008) examining individual-level and system-level outcomes over time and across community corrections districts and judicial actors. The study also assesses the impact of SB 123 on the work routines of criminal justice system actors, examining changes in sentencing and supervision practices and interactions across agencies following the implementation of SB 123.

Individual-level impacts of SB 123 on recidivism rates are assessed using sentencing and revocation data collected by the Kansas Sentencing Commission for drug possessors sentenced in Kansas between November 1, 2001 and October 31, 2008 (Dataset 1). Propensity score matching was used to compare the revocation and reconviction rates of drug possessors sentenced to SB 123 with the recidivism rates of similar individuals sentenced to regular probation (standard supervision by community corrections or court services) (Dataset 2). Supervision and program participation data provided by the Kansas Department of Corrections were used to assess the use of drug treatment services, education and employment services, and sanctions for individuals sentenced to SB 123 or standard community corrections (Dataset 3). These quantitative data were complemented by a set qualitative data derived from interviews with SB 123-eligible offenders (Dataset 4), community corrections managers, and courtroom actors (judges, prosecutors, public defenders) (Dataset 5).

Census of Problem-Solving Courts, 2012 (ICPSR 36717)

Released/updated on: 2017-04-06
Geographic coverage: United States

With the creation of the first drug court in Miami-Dade County, Florida in 1989, problem-solving courts emerged as an innovative effort to close the revolving door of recidivism. Designed to target the social and psychological problems underlying certain types of criminal behavior, the problem-solving model boasts a community-based, therapeutic approach. As a result of the anecdotal successes of early drug courts, states expanded the problem-solving court model by developing specialized courts or court dockets to address a number of social problems. Although the number and types of problem-solving courts has been expanding, the formal research and statistical information regarding the operations and models of these programs has not grown at the same rate. Multiple organizations have started mapping the variety of problem-solving courts in the county; however, a national catalogue of problem-solving court infrastructure is lacking. As evidence of this, different counts of problem-solving courts have been offered by different groups, and a likely part of the discrepancy lies in disagreements about how to define and identify a problem-solving court. What is known about problem-solving courts is therefore limited to evaluation or outcome analyses of specific court programs.

In 2010, the Bureau of Justice Statistics awarded the National Center for State Courts a grant to develop accurate and reliable national statistics regarding problem-solving court operations, staffing, and participant characteristics. The NCSC, with assistance from the National Drug Court Institute (NDCI), produced the resulting Census of Problem-Solving Courts which captures information on over 3,000 problem-solving courts that were operational in 2012.

Empirical Investigation of "Going to Scale" in Drug Interventions in the United States, 1990, 2003 (ICPSR 26101)

Released/updated on: 2009-08-26
Geographic coverage: United States
Despite a growing consensus among scholars that substance abuse treatment is effective in reducing offending, strict eligibility rules have limited the impact of current models of therapeutic jurisprudence on public safety. This research effort was aimed at providing policy makers some guidance on whether expanding this model to more drug-involved offenders is cost-beneficial. Since data needed for providing evidence-based analysis of this issue were not readily available, micro-level data from three nationally representative sources were used to construct a 40,320 case synthetic dataset -- defined using population profiles rather than sampled observation -- that was used to estimate the benefits of going to scale in treating drug involved offenders. The principal investigators combined information from the NATIONAL SURVEY ON DRUG USE AND HEALTH, 2003 (ICPSR 4138) and the ARRESTEE DRUG ABUSE MONITORING (ADAM) PROGRAM IN THE UNITED STATES, 2003 (ICPSR 4020) to estimate the likelihood of drug addiction or dependence problems and develop nationally representative prevalence estimates. They used information in the DRUG ABUSE TREATMENT OUTCOME STUDY (DATOS), 1991-1994 (ICPSR 2258) to compute expected crime reducing benefits of treating various types of drug involved offenders under four different treatment modalities. The project computed expected crime reducing benefits that were conditional on treatment modality as well as arrestee attributes and risk of drug dependence or abuse. Moreover, the principal investigators obtained estimates of crime reducing benefits for all crimes as well as select sub-types. Variables include age, race, gender, offense, history of violence, history of treatment, co-occurring alcohol problem, criminal justice system status, geographic location, arrest history, and a total of 134 prevalence and treatment effect estimates and variances.

Evidence-Based Screening and Assessment: A Randomized Trial of a Validated Assessment Tool in Three New York City Drug Courts, 2011-2015 (ICPSR 36310)

Released/updated on: 2022-07-28
Geographic coverage: New York City, United States, New York (state)
Time period: 2011-04-01--2015-04-30
With funding from the National Institute of Justice, the Center for Court Innovation examined the impact of introducing an evidence-based risk-need assessment and treatment matching protocol into three New York City drug courts. Preexisting practice in all three sites involved administration of a non-validated bio-psychosocial assessment, whose results informed the professional judgment of court-employed case managers, but without the aid of a structured decision making system.

Examining the Multifaceted Impacts of Drug Decriminalization on Public Safety, Law Enforcement, and Prosecutorial Discretion, Oregon, 2008-2024 (ICPSR 39669)

Released/updated on: 2026-03-11
Geographic coverage: Oregon, United States
Time period: 2008-01-01--2024-01-01

This project sought to understand the effects of successive drug policy reforms in the state of Oregon. These include three changes since 2013 to reduce the enforcement and punishment of low-level drug possession. House Bill 3194 passed in 2013, which reduced mandatory minimum sentences for marijuana offenses and diverted more driving and drug-related offenses to probation. House Bill 2355 passed in 2017, which reclassified Schedule I and II possession of controlled substance (PCS), reducing these from a moderate felony to a misdemeanor. Then in 2021, M110 was implemented, downgrading certain quantities of PCS from a misdemeanor to a citation, resulting in a maximum 100 dollar fine or completed health assessment.

The researchers conducted a retrospective longitudinal analysis using statewide administrative data to assess the impacts of these drug law reforms. Measures included police stops, PCS arrests, court filings, convictions, jail and prison admissions, crime rates, drug seizures, and drug-related overdose deaths.

Multi-Site Adult Drug Court Evaluation (MADCE), 2003-2009 (ICPSR 30983)

Released/updated on: 2012-11-05
Geographic coverage: North Carolina, New York, United States, Illinois, Georgia, Florida, Washington, South Carolina, Pennsylvania
Time period: 2004-02-01--2004-06-01, 2005-03-01--2006-06-01, 2005-08-01--2006-12-01, 2006-09-01--2008-01-01, 2006-09-01--2008-01-01

The Multi-Site Adult Drug Court Evaluation (MADCE) study included 23 drug courts and 6 comparison sites selected from 8 states across the country. The purpose of the study was to: (1) Test whether drug courts reduce drug use, crime, and multiple other problems associated with drug abuse, in comparision with similar offenders not exposed to drug courts, (2) address how drug courts work and for whom by isolating key individual and program factors that make drug courts more or less effective in achieving their desired outcomes, (3) explain how offender attitudes and behaviors change when they are exposed to drug courts and how these changes help explain the effectiveness of drug court programs, and (4) examine whether drug courts generate cost savings.

Offenders in all 29 sites were surveyed in 3 waves, at baseline, 6 months later, and 18 months after enrollment. The research comprises three major components: process evaluation, impact evaluation, and a cost-benefit analysis. The process evaluation describes how the 23 drug court sites vary in program eligibility, supervision, treatment, team collaboration, and other key policies and practices. The impact evaluation examines whether drug courts produce better outcomes than comparison sites and tests which court policies and offender attitudes might explain those effects. The cost-benefit analysis evaluates drug court costs and benefits.
