Evaluation of an inpatient sex offender treatment programme for men with intellectual disabilities

Abstract

Purpose The purpose of this paper is to report on an inpatient cognitive behavioural sex offender treatment group programme developed and provided to people with intellectual disabilities detained in medium and low security hospital settings. The programme was delivered five times between 2012 and 2020. This paper describes the integration of the programme within a wider treatment pathway model and provides analysis of outcome data. Design/methodology/approach The programme was evaluated over five group programmes using self-report psychometric measures related to treatment targets in the reduction of sexual offending risk, including cognitive distortions, sexual attitudes and knowledge and locus of control; recidivism data spanning up to 7 years post discharge is also provided. The treatment pathway and a description of the programme are provided. Findings The results of this paper showed improvements in sexual knowledge, cognitive distortions and locus of control, however not to a statistically significant degree. No recidivism was observed in the follow-up period. Originality/value This paper adds to the evidence base of interventions focused on cognitive behavioural approaches to the treatment and risk reduction of sexual offending in men with intellectual disabilities and adds to the debate regarding the effectiveness of such programmes with offenders with intellectual disabilities.
