A cost–benefit analysis of a treatment program for adult males who have offended sexually

ABSTRACT In this paper, we estimate the financial benefits that can result from effective sexual offender treatment. We base our estimates on both an earlier outcome evaluation of a prison-based sexual offender programme and a report of the costs to the judicial system of reoffending. The outcome study reported significant reductions in re-offence rates compared to a matched group of untreated sexual offenders. We show that these reductions in reoffending not only saved a significant number of people from subsequently being abused by the offenders, it also resulted in very significant savings to the taxpayers to the tune of over $14 million Canadian. While these results are encouraging, additional studies are needed to extend the examination of these potential benefits.
