Validating the principles of effective intervention: A systematic review of the contributions of meta-analysis in the field of corrections

Abstract

This systematic review evaluates the contributions of meta-analysis in the field of corrections and offender rehabilitation. The article explores the Principles of Effective Intervention (PEI)—risk, need, and responsivity—and their role in identifying "what works" in reducing recidivism. The review synthesises findings from over 40 meta-analyses conducted in the field of corrections, demonstrating the effectiveness of structured, evidence-based programs over non-specific interventions. The study also highlights the importance of matching interventions to offender risk levels, targeting criminogenic needs, and ensuring program integrity. The findings have significant implications for correctional policy and rehabilitation practices.
