The effectiveness of a prison-based cognitive behavioral program designed to modify psychological risk factors associated with sexual offending was evaluated. The Irish Prison Service Sexual Offender Intervention Programme, is a manualized 10-month Cognitive Behaviour Therapy [CBT] program involving three 2-hour group sessions per week, which are facilitated by a team of clinical psychologists and probation officers. Improvements in 38 consecutive referrals to the program were compared with the status of 38 untreated offenders who were similar in marital status, age when they left school, occupational status prior to imprisonment, offence type, presence of previous convictions, and current sentence length. All research participants completed the same assessment protocol, which evaluated psychological factors associated with sexual offending at times equivalent to pre- and postintervention. Compared with the untreated control group, program participants showed statistically significant improvement on some but not all self-report measures of cognitive distortions, empathy, interpersonal skills, self-regulation, and relapse prevention. Motivation to change among the untreated control group was not associated with change in psychological functioning in the absence of the assistance of the treatment program. Implications for sexual offender intervention delivery are considered.

This study evaluated the factor structures of three instruments from the Sexual Offender Assessment Pack. The Children and Sex Cognitive Distortions Scale, the Children and Sex Emotional Congruence Scale, and the Child Victim Empathy Distortions Scale were administered to 203 sex offenders in Ireland. Confirmatory factor analyses did not support the proposed single factor structure for each of the three scales. Exploratory factor analyses suggested more complex factor structures. The Children and Sex Cognitive Distortions Scale was found to have two factors: (a) Perceptions of Children as Sexually Mature and (b) General Justifications for Sex With Children. The Children and Sex Emotional Congruence Scale was found to have three factors: (a) Positive Affect From Children, (b) Special Relationships With Children and (c) Preference for Relationships With Children. The Victim Empathy Scale was found to have two factors: (a) Positive Misattributions of Pleasure and (b) Denial of Negative Feelings in the Child. In clinical settings, the more complex factor structures identified in this study may used in scoring and interpreting responses to the three instruments investigated here. Our results require replication and further research should focus on the correlates of the factorial scales identified in this study.
