Procedural Justice in Policing: How the Process of Justice Impacts Public Attitudes and Law Enforcement Outcomes
November 7, 2017 | Article | Law Enforcement
An increasing number of widely publicized and divisive incidents between police and citizens suggest a need for police policies and practices to improve procedural justice. Procedural justice emphasizes the need for police to demonstrate their legitimacy to the public in four areas—voice, transparency, fairness, and impartiality. This article explains procedural justice and police legitimacy, examines the often racial divide between citizens and police, and offers implications for police policy and practice.

Victim Need Report: Service Providers’ Perspectives on the Needs of Crime Victims and Service Gaps
November 3, 2017 | Article, Research Report | Victimization
Researchers conducted a statewide study to better understand crime victim needs, identify service gaps, and measure the capacity of Illinois victim service providers. Victim service providers from across Illinois identified the needs of violent crime victims. Providers also highlighted service gaps, or ways in which current service availability was unable to satisfy victim need. Study findings have policy and practice implications for funders, victim service providers, and other service agencies that interact with victims in Illinois.

Police-Led Referrals to Treatment for Substance Use Disorders in Rural Illinois: An Examination of the Safe Passage Initiative
October 3, 2017 | Article | Law Enforcement
Researchers conducted a process evaluation of Safe Passage, a police deflection model in which police departments become a referral point to treatment for individuals with substance use disorders. Through the model, individuals can walk into any participating police department and request and receive treatment without fear of arrest. In Illinois, Safe Passage has served 170 individuals in rural Lee and Whiteside counties since 2015. Researchers sought to understand how the initiative was developed and operated and gain perspectives of stakeholders, police officers, treatment providers, and clients involved in the program. While more research is needed, the initiative showed promise in its collaborative approach to connecting clients to treatment.

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.

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.
