A robust method for the evaluation of prison based sex offender treatment programmes

This paper outlines the approach to evaluating the sex offender treatment programme currently running in the Irish prison system. It begins with an introduction to the scope of the problem of sexual offending as reflected by the extent of the prison population in Ireland who have been convicted of a variety of sexual offences. It then outlines two key points that can be gleaned from several decades of general research on evaluating the effectiveness of psychological treatments while indicating how they have been included in our present research. We also describe the variety of data sources that need to be incorporated into an effective evaluation of prison based sex offender treatment programmes. We conclude with an introduction to some preliminary findings from our on-going research. These finding high-light the return in terms of more reliable information when care is taken in developing a robust method for the evaluation of prison-based sex offender treatment programmes.
