The national assessment focuses on understanding the effectiveness of the “enhanced PSN” model for reducing violent crime and the factors that influence effectiveness. COVID-19 presented a major disruption to PSN efforts, but with the FBI’s release of 2022 Uniform Crime Report (UCR) data, the evaluation could assess the relationship between PSN implementation and crime outcomes in the post-COVID period. This presentation summarizes findings from the national assessment of PSN from 2018 through the beginning of fiscal year 2022, following revisions to the enhanced model. It then focuses on the most recent post-COVID wave of the national assessment, using primary data collected through interviews with PSN Coordinators and a survey of PSN stakeholders to measure PSN implementation. Changes in crime from October of 2021 through December 2022 are measured using imputed UCR data for violent crime, homicide, robbery, robbery with a firearm, aggravated assault, and aggravated assault with a firearm.
Jurisdiction-level data on violent crimes, population, and contextual factors from the American Community Survey are aggregated to the Federal district level. Crime trends are modeled as a function of PSN implementation characteristics to provide practical information for practitioners about the relationship between different PSN efforts and reductions in violent crime.
