Abstract Existing research offers considerable direction on theoretically grounded strategies for crime prevention, where treatment should be delivered, and when treatment should be applied; however, much less is known about the amount of treatment ideally needed to generate a reduction in violent crime. The current study fills this gap by examining the following critical questions: (1) What is the relationship between treatment dosage applied to hot spots and the immediate impact on violent street crime? (2) What is the relationship between treatment dosage applied to hot spots and the subsequent impact on violent street crime? (3) Does the relationship between treatment dosage and violent crime incidents vary depending on the preintervention level of violent crime? Data from four cities across two years were used to address these research questions. Results provide guidance on the relationship between amount of treatment and crime reduction at hot spot locations including specific recommendations depending on city size.
