Fighting the Opioid Crisis through Substance Use Disorder Treatment: A Study of a Police Program Model in Illinois
September 7, 2017 | Article | Law enforcement
Seeking to more effectively help individuals suffering from opioid use disorder, police departments across the country are embracing a deflection model that offers treatment access to those in need. Researchers interviewed representatives of seven law enforcement agencies employing treatment program models in Illinois to better understand operations, leverage lessons learned, measure sustainability, and inform other agencies as they implement their own programs.

An Examination of Fear of Crime and Social Vulnerability in Chicago Neighborhoods
August 16, 2017 | Article | Community violence
Although there have been documented declines in U.S. crime rates in past decades, recent news headlines in Chicago often highlight incidents of, and concerns about, violence, particularly gun violence. Prior research has noted fear of crime in urban neighborhoods is associated with physical deterioration, as well as social disorganization and vulnerability. ICJIA researchers surveyed more than 1,000 Chicago residents in 16 neighborhoods on fear of crime and compared their responses to a measure of neighborhood social vulnerability. This study found an association between social vulnerability and fear of crime. In addition, half of the residents had greater fear than expected based on neighborhood social vulnerability and half had less fear of crime than expected. Future research can serve to understand the impact of, and ways to reduce, unwarranted fear that can have a negative impact on individuals.

A Comprehensive Model for Underserved Victims of Violent Crime: Trauma Recovery Centers
August 4, 2017 | Article | Victimization
Violent crime victimization can impact multiple areas of victims’ lives. Victims who are underserved or marginalized face unique individual, societal, and cultural hurdles that impact help-seeking. Models of service delivery that provide a single point of contact and comprehensive, evidence-based services hold promise to serve victims whose needs extend beyond traditional services. Comprehensive trauma recovery center (TRC) models have been shown to lead to positive survivor outcomes. TRC model expansion should be explored to assess how they might complement existing services and reach underserved individuals and groups.

An Examination of Traumatic Experiences and Posttraumatic Stress Disorder Among a Sample of Illinois Prisoners
July 25, 2017 | Article | Corrections
Research has found nearly all prisoners have experienced a traumatic event in their life and a high proportion suffer from PTSD. Illinois Criminal Justice Information Authority and WestCare Foundation (Illinois) researchers surveyed 573 Illinois prisoners to understand the trauma they experienced and explore the relationship between trauma and substance misuse. Researchers found 89 percent of those surveyed had both experienced and witnessed more than one traumatic event during their lifetime. Almost one-fourth of the sample were identified as being symptomatic for PTSD (24 percent). In addition, researchers found a relationship found between greater PTSD symptoms and higher drug use. This article describes survey findings and provides implications for policy and practice in correctional facilities.

Trauma-Informed and Evidence-Based Practices and Programs to Address Trauma in Correctional Settings
July 25, 2017 | Article | Corrections
The prevalence of trauma and posttraumatic stress disorder (PTSD) is higher among individuals in prison and jail than in the general population. Research has shown a connection between trauma and criminality due in part to the coping mechanisms of aggression and substance misuse after a traumatic event. While the corrections environment itself may cause or exacerbate PTSD symptoms in some individuals, facilities can implement trauma-informed practices to minimize re-traumatization and reduce PTSD symptoms. This article documents the prevalence of trauma and PTSD within this population, and discusses how correctional facilities can implement trauma-informed practices and evidence-based approaches to assist individuals with trauma histories.

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.

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.

Scatter Plot Analysis Tool 

These tools come with a variety of built-in Help features to assist users as they navigate the unique analysis functions.
