Abstract

What works seeks to identify rehabilitative treatments which are successful in reducing the likelihood that offenders will reoffend. A large number of small case-control studies have been reported in the literature, but withconflicting results. Meta-analysis has been used to reconcile these findings, but again with conflicting results. We reanalyse one of the published meta-analyses in the corrections literature and argue the importance of specifically modelling heterogeneity and selection bias. A sensitivity approachis advocated, suggesting lower average effects and substantially increasedmeasures of uncertainty. The method is tested on a medical example where independent confirmation from a large controlled trial is also available.
