Follow-Up: Sex Offenders with Intellectual Disabilities 1 Running Head: Follow-Up: Sex Offenders with Intellectual Disabilities Men with Intellectual Disabilities who have Attended Sex Offender Treatment Groups: A Follow-Up

Background: There have been a number of studies of treatment for men with intellectual disabilities and sexually abusive behavior but few follow-up studies. Our aim was to follow-up men with intellectual disabilities who had attended group cognitivebehavioural treatment (CBT) for sexually abusive behaviour. Method: 34 men (from seven treatment sites) were followed-up. All had attended SOTSEC-ID groups. The mean length of follow-up, since the end of the treatment group, was 44 months (s.d. 28.7, range 15 106 months). Measures were used to evaluate changes in sexual knowledge, cognitive distortions and victim empathy. Repeat sexually abusive behaviour was also assessed. Results: The statistically significant improvements in sexual knowledge, empathy and cognitive distortions that occurred during treatment were maintained at follow-up. In all, 11 of the 34 (32%) men showed further sexually abusive behavior at some point after their treatment group started, counting up to this follow-up point. Only two of these 11 men received convictions for this behaviour. Analyses of the variables associated with further sexually abusive behavior indicated that a diagnosis of autism was associated with a higher likelihood of further sexually abusive behaviour. Conclusions: This study provides some evidence of the longer term effectiveness of group CBT for men with intellectual disabilities and sexually abusive behavior, but there remains a need for further follow-up studies of large samples and a randomised controlled trial.
