Introduction

Abstract

This article aims to review the effectiveness of the “Reasoning and Rehabilitation” programme in reducing recidivism. Sixteen evaluations (involving 26 separate comparisons) were located in which experimental and control groups were compared. A meta-analysis showed that, overall, there was a significant 14% decrease in recidivism for programme participants compared with controls. This programme was effective in Canada, the USA, and the UK. It was effective in community and institutional settings, and for low risk and high-risk offenders. Smaller and larger evaluation studies, and older and newer studies, concluded that the programme was effective. Future evaluations should use larger samples, randomized controlled trials and better measures of recidivism (including self-reports, numbers, types and costs of offences committed).
