The relationship between psychometric test scores and reconviction in sexual offenders undertaking treatment

Abstract The evidence is mixed regarding the utility of psychometric test scores in prediction of the likelihood of sexual reoffending. This paper summarizes the research examining the relationship between psychometric measures and sexual recidivism, before detailing the findings of four large-scale studies in England and Wales, and comparing the findings of these studies to similar studies from other countries. The implications of the evidence to date are discussed, and recommendations are made for the future of psychometric testing as a way of determining risk of recidivism, dynamic risk factors, change over treatment, and the efficacy of rehabilitative programs.
