Evidence-based practices

At this Research for the Real World seminar, NIJ brought together law enforcement practitioners and leading researchers in the field of stress to discuss the current research evidence and practical benefits of targeted stress-management interventions and how they can promote officer mental wellness.

This video, produced for IACPTV, provides an overview of the NIJ Law Enforcement Advancing Data and Science (LEADS) program. NIJ LEADS Scholars from Dayton and Newark police departments provide an overview of the LEADS program as they describe their projects and experiences working in the program.

Hear from LEADS scholars Major Wendy Stiver, Dayton Police Department, and Captain Ivonne Roman, Newark Police Department.

Researchers have devoted considerable attention to mass incarceration, specifically its magnitude, costs, and collateral consequences. In the face of economic constraints, strategies to reduce correctional populations while maintaining public safety are becoming a fiscal necessity. This panel will present strategies that states have undertaken to reduce incarceration rates while balancing taxpayer costs with ensuring public safety.

Dr. Campbell brings together research on the neurobiology of trauma and the criminal justice response to sexual assault. She explains the underlying neurobiology of traumatic events, its emotional and physical manifestation, and how these processes can impact the investigation and prosecution of sexual assaults. Real-world, practical implications are examined for first responders, such as law enforcement, nurses, prosecutors, and advocates.

Change doesn't come easy, particularly within an institution as large and complex as the criminal justice system. Greg Berman, Director of the Center for Court Innovation, offered lessons from several efforts to make reform stick in criminal justice settings. In particular, he focused on the development of community courts — experimental court projects that are attempting to reduce both crime and incarceration in dozens of cities across the U.S. and around the world.

Research tells us that a relatively small fraction of individuals experience a large proportion of violent victimizations. Thus, focusing on reducing repeat victimization might have a large impact on total rates of violence. However, research also tells us that most violent crime victims do not experience more than one incident during a six-month or one-year time period. As a result, special policies to prevent repeat violence may not be cost-effective for most victims.

Professor Ed Latessa describes how his team and he assessed more than 550 programs and saw the best and the worst. Professor Latessa shared his lessons learned and examples of states that are trying to use evidence-based knowledge to improve correctional programs.

David Olds, founder of the Nurse-Family Partnership Program, describes the programs long-term impact on mothers and babies who began participating in the program more than 19 years ago. The Nurse-Family Partnership maternal health program introduces vulnerable first-time parents to maternal and child health nurses. It allows nurses to deliver the support first-time moms need to have a healthy pregnancy, become knowledgeable and responsible parents, and provide their babies and later children and young adults with the best possible start in life.

Professor Rosenbaum and a panel of colleagues discuss a study to demonstrate the feasibility of creating a foundation from which to launch studies about multiple aspects of policing using standardized definitions and measurement tools. Their goal is to advance knowledge about policing and translate data into evidence-based best practices that improve training, supervision and accountability systems. The effort is expected to produce a better understanding of what motivates police officers and makes them healthier, happier and more effective.

A small number of those who commit crimes are heavily involved in drugs commit a large portion of the crime in this country. An evaluation of a "smart supervision" effort in Hawaii that uses swift and certain sanctioning showed that individuals committing crimes who are heavily involved in drug use can indeed change their behavior when the supervision is properly implemented.

The criminal justice system encounters and supervises a large number of drug abusing persons. Punishment alone is a futile and ineffective response to the problem of drug abuse. Addiction is a chronic brain disease with a strong genetic component that in most instances requires treatment. Involvement in the criminal justice system provides a unique opportunity to treat drug abuse disorders and related health conditions, thereby improving public health and safety.
