It was not so long ago that scholarly writings pointed to the vast chasm that existed between criminal justice and public health approaches to understanding and controlling interpersonal violence. Other scholarship of the day examined how criminal justice and criminology could benefit from adopting elements of the public health approach. For sure, there still exist many differences in how the two disciplines approach the violence problem, but over the years there have been some promising developments at the intersection of public health and criminology. This paper surveys the evolving link between public health and criminology, with a special focus on serious youth violence. It is concerned with both research and practice and how these efforts—across primary, secondary, and tertiary prevention strategies—are contributing to improved public health-criminology collaborations or public health-influenced programs that have a discernable impact on youth violence.
