UC expert believes sex offenders can be effectively rehabilitated
August 15, 2013
A University of Canterbury (UC) expert believes sex offenders can be effectively rehabilitated.
UC research has found that psychological treatment for sexual offenders is effective and offenders who show more
improvement in treatment are less likely to re-offend.
UC Professor Randolph Grace says demonstrating a causal link between prison-based treatment programmes and reductions in
re-offending is challenging.
``Our research here has been the first in the world to demonstrate that specific treatment was linked to reductions in
recidivism by sexual offenders.
``Offenders who had more treatment were less likely to re-offend. We compared criminal histories for New Zealand men who
were treated at Rolleston Prison’s Kia Marama unit near Christchurch and results suggest that many of these offenders
are less likely to re-offend.
``There’s a lot of debate about the efficacy of psychological treatment for sexual offenders and a lot of technical
issues as to why it’s a difficult question to resolve.
``We have considered the post-release outcomes for 428 sexual offenders who were treated at Rolleston Prison’s Kia
Marama unit. They were compared with a cohort of 1956 offenders who were also incarcerated for sexual offending but did
not receive comparable treatment.
``We found the Kia Marama psychological treatment programme was associated with a 29 percent reduction in sexual
re-offending and the reduction was statistically significant.
``There were also significant reductions in violent and general re-offending for the Kia Marama group.’’
The UC study has been published in the Journal of Consulting and Clinical Psychology and was important because it was the first to demonstrate that specific treatment gains were linked to reductions in
recidivism by sexual offenders.
The Kia Marama Unit was founded in 1989 through the efforts of the late UC Associate Professor Steve Hudson, who
previously taught in the clinical psychology programme.
Although results of some overseas studies on the effectiveness of psychological treatment for sex offenders have been
contentious, the recent UC research at Kia Marama has provided some of the strongest evidence yet that treatment does
work.
Professor Grace will give a public lecture on campus next week (August 21) about the issue of treatment and a reduction
in offending. See here for details: http://www.canterbury.ac.nz/wiw/.
