Research

The VRC produces high quality research with concrete implications for anti-violence policy and practice. Emphasizing cumulative knowledge building, the VRC performs systematic reviews, evidence gap maps, replication studies, and other work to overcome internal and external validity challenges. Our goal is to give policymakers and practitioners access to a body of evidence that is reliable and robust enough to inform concrete conclusions about what to do about community gun violence in the real world.

In late 2023, in partnership with professors Ericka Adams of San José State University and  Ed Maguire and Cody Telep of Arizona State University, the VRC will complete a Campbell Collaboration systematic review of street outreach programs to determine whether such initiatives effectively reduce violence. These programs have gained popularity in recent years, with substantial increases in funding being directed towards community-oriented, street-based violence reduction strategies. The review will assist policymakers, practitioners, and the public in better understanding the effects of such programs. For more information, review the title registration here.

Also in late 2023, working with professors David Wilson and Catherine Kimbrell of George Mason University, the VRC will complete a Campbell Collaboration systematic meta-review, updating Thomas Abt and Christopher Winship’s original 2016 meta-review on the topic. The study will report the results of systematic reviews of interventions intended to directly or indirectly reduce community violence to assist policymakers, researchers, and the public in better understanding what works to best reduce community violence.

In early 2024, the VRC will publish its flagship product – an online registry of anti-violence strategies supported by systematic reviews of experimental and quasi-experimental evidence.
