An Overview of Medication-Assisted Treatment for Opioid Use Disorders for Criminal Justice-Involved Individuals
July 18, 2017 | Article | Treatment for Opioid Use Disorders (OUD)
There is a national opioid epidemic and one intervention to help those suffering from an opioid use disorder (OUD) is medication-assisted treatment (MAT). MAT is the use of medications in conjunction with behavioral therapy as part of a long-term treatment regimen. There are three main MAT medications used today—methadone, buprenorphine, and naltrexone. Research has shown MAT, in particular the use of methadone or buprenorphine, is considered an evidence-based practice to treat OUD. Studies indicate those in MAT have better outcomes than those who engage in therapy alone. This article provides an overview of MAT with a focus on use with criminal justice populations.

Juvenile Justice in Illinois, 2015
July 12, 2017 | Article | Juvenile Justice, Juveniles

Juvenile Justice in Illinois, 2015, provides a statistical overview of the juvenile justice system in Illinois across four decision points in which data were available: arrest, detention admissions, active probation caseloads, and new sentence admissions to corrections. Statewide and regional figures are provided with rates spanning from 2011 to 2015. In addition, population, demographic, and offense type information is provided for decision points in which data were available in 2015. Overall, rates for arrest, active probation caseload, detention admissions, and new sentence admissions to corrections have decreased between 2011 and 2015; however, the Central and Southern regions had slight increases in detention admission rates.

Community Violence Prevention, Intervention, and Suppression
June 21, 2017 | Article | Community Violence
Addressing street-level violence such as murders and aggravated assaults and batteries that occur on the public way and often involve firearms requires a multi-pronged approach. One effective model for addressing street violence, and, in particular, gang-related or group-involved street violence, is the Office of Juvenile Justice and Delinquency Prevention’s (OJJDP) Comprehensive Gang Prevention, Intervention, and Suppression Model. The model involves implementing complementary and coordinated prevention, intervention, and suppression activities in a single community. This article provides examples of evidence-based practices and programs that strengthen youth resilience and build social capital and work to reduce threats or perceived threats using the OJJDP model as a framework. The article also highlights how the model is enhanced when community stakeholders consider how trauma has impacted residents and those targeted by intervention and suppression efforts.

Study of Self-Reported Prescription Drug Use Among a Sample of Illinois Prisoners
June 15, 2017 | Article | Substance use disorders, corrections, prison, prescription drug use
While more than half of individuals incarcerated in U.S. jails and prisons meet the diagnostic criteria for a substance use disorder, little is known about their misuse of prescription drugs. In this study, Authority researchers, in collaboration with WestCare Foundation Illinois, surveyed 573 state prisoners on prescription drug use to examine prevalence, accessibility, motivation for use, and effects. Forty-six percent of the sample reported using prescription drugs to get high and 20 percent used prescription drugs daily in the year before their incarceration.

Using U.S. Law-Enforcement Data: Promise and Limits in Measuring Human Trafficking
April 4, 2017 | Article | Law Enforcement
Over the past decade, federal, state, and local law enforcement have increasingly been called upon to identify and investigate human-trafficking offenses. Numerous efforts have been put in place to track incidents, arrests, and criminal offenses related to human trafficking. In response to directives from the William Wilberforce Trafficking Victims Protection Reauthorization Act (2008), the FBI added two new crime categories to the Uniform Crime Reporting Program (UCR) to capture commercial-sex acts and involuntary servitude. Additionally, in an effort to improve our understanding of the prevalence of human trafficking in the United States, state legislatures have begun to require the collection of data on human trafficking offenses identified by criminal-justice officials. However, despite the promises of standardized data from law enforcement about human trafficking, the numbers of reported human-trafficking offenses and arrests have been low. In this article, we examine official counts of human trafficking collected by criminal-justice-system data programs. We draw on data from a survey of state crime-reporting agencies and case studies of human trafficking crime reporting conducted in two U.S. states to explore the challenges that local police agencies face reporting human trafficking. Finally, we offer suggestions for improving officially reported data.

Illinois Drug Threat Assessment: A Survey of Police Chiefs and County Sheriffs
March 9, 2017 | Report | Law enforcement
It is important for states to understand current drug and crime trends in order to be proactive. Local law enforcement can provide important contributions in identifying emerging drug and crime trends as frontline officers. To get the local law enforcement perspective, the Illinois Criminal Justice Information Authority administered a survey to Illinois police chiefs and county sheriffs to gain insight regarding drug trafficking in their jurisdiction. Eighty-three police chiefs and county sheriffs responded to the survey, most frequently identifying heroin and prescription drugs as the greatest drug threats in their jurisdictions. Methamphetamine was also reported as the greatest drug threat in the central and southern regions of Illinois. This article is a summary of key findings of the full report.

Study of self-reported synthetic drug use among a sample of Illinois prisoners
February 17, 2017 | Article | Synthetic Drug Use
Synthetic drug use is a growing public health concern. Synthetics are often cheaper and more readily available than cannabis and amphetamines, making them attractive alternatives to other illicit drugs. In addition, the chemical formulas for these drugs are constantly changing, making them difficult to regulate, and their detection is limited in commonly used drug screenings. Authority researchers partnered with WestCare Foundation to survey 573 state prisoners on synthetic drug use to examine prevalence, accessibility, motivation for use, and effects. Thirty-six percent of respondents reported any synthetic drug use in their lifetime prior to incarceration. Findings suggested a proportion of the criminal justice population engages in synthetic drug use and the findings were consistent with other research on synthetic drug use.

An examination of juvenile sex offenders in the Illinois juvenile justice system
February 14, 2017 | Full Report | Juvenile Sex Offenders
Juveniles adjudicated delinquent for a sex offense can result in lifelong consequences, including sex offender registration. Further, there can be repercussions financially, emotionally, and socially for a juvenile and his/her family that extend throughout the individual’s life. Given the potential negative impact of sex offender registration, it is important to understand the implications of the registry within the larger context of youth development and juvenile justice. This report analyzes characteristics of youth arrested, detained, and admitted to corrections in Illinois in 2014 and associated trends from 2004 to 2014.

Crime & Risk Factor Data Tools

With support from the U.S. Department of Justice, Bureau of Justice Statistics, ICJIA has developed several data analysis and dissemination tools to give users convenient and flexible ways to access and interact with ICJIA’s extensive criminal justice and associated risk factor data holdings.

Criminal Justice Data Profiles

The Criminal Justice Data Profiles tool offers criminal justice indicators that allow users to create county, judicial circuit, and statewide profiles. These profiles may be used to inform planning and policy decisions.

Criminal Justice Data Profiles 

Criminal history and recidivism tool

The Criminal History and Recidivism Tool provides information on the patterns of prior criminal history of various cohorts of persons sentenced to prison in Illinois, and their long-term recidivism rates upon release. Tables and charts display several types of information: demographic information on the selected group of interest; the number and types of prior arrests, convictions, probation and prison sentences; and post-release recidivism rates based on multiple types of criminal justice events and demographic categories.

Criminal History and Recidivism Tool 

Single Map Analysis Tool

The Single Map Analysis Tool is useful for those interested in a visual snapshot of how Illinois counties compare on various crime and criminal justice indicators. The tool displays this information in two interactive formats; as an Illinois map, and as corresponding trend lines over the previous ten years. Users can select any number of counties, regions or judicial circuits for comparison.

Single Map Analysis Tool 

Scatter Plot Analysis Tool

The Scatter Plot Analysis Tool allows users to compare the relationship between two different criminal justice indicators within a county, and determine how all Illinois counties rank on that joint set of crime statistics or criminal justice indicators. The tool displays this information in several interactive formats; as Illinois maps and as a corresponding scatter plot showing correlations for all counties or custom sets of counties in Illinois.
