The relationship between victimization and offending, also referred to as the victim-offender overlap, is widely documented.

This article outlines leading theoretical explanations for the victim-offender overlap, factors that influence victimization and offending, and recommendations for practitioners to address violent victimization and prevent subsequent offending.
