RT Article T1 Implementation outcomes of the Philadelphia Police School Diversion Program: A school-based alternative-to-arrest initiative JF Journal of crime and justice VO 48 IS 1 SP 73 OP 95 A1 NeMoyer, Amanda A2 Pollard, Angela A2 Le, TuQuynh A2 Kreimer, Rena A2 Lattanzio, Matthew A2 Goldstein, Naomi E.S. LA English YR 2025 UL https://krimdok.uni-tuebingen.de/Record/1915603714 AB Evaluations of juvenile and criminal legal system programs typically focus on outcomes related to program impacts, or effectiveness. However, implementation outcomes – which relate to the processes underlying program execution – are equally as critical to determining program success. Adding to the burgeoning interest in applying implementation science principles to legal system interventions, the current study examined implementation outcomes of the Philadelphia Police School Diversion Program – a school-based, alternative-to-arrest program that has already demonstrated promising effectiveness outcomes. Through qualitative analysis of semi-structured interviews with 11 school and police stakeholders and quantitative analysis of police data for 2,047 school-based arrests in Philadelphia that occurred during the first five years of program operation, we explored outcomes related to Diversion Program adoption, appropriateness, acceptability, fidelity, penetration/reach, and sustainability, as well as stakeholder thoughts about program expansion and replication. Results revealed several important components of program implementation that contributed to its widespread adoption and sustained operations.
