Pedophilic interest is a central risk factor for sexual offending against children. Multiple measures exist to assess pedophilic interest, and the present study aims to provide validity evidence for three of these measures in a sample of men convicted of sexual offenses. The association between a phallometric test for pedophilic interest, the Screening Scale for Pedophilic Interest (SSPI), and the sexual deviance factor of the Violence Risk Scale–Sexual Offense (VRS-SO) version was examined in a sample of 261 men who participated in sexual violence reduction services. The association between these measures and sexual recidivism, both as sole predictors and while controlling for static risk, was also assessed. The second aim of the study was to examine the validity of different methods for modeling the distribution of pedophilic interests, using phallometric test scores, based on the findings in recent taxometric research. The measures generally showed a positive and moderate relationship with each other and predicted sexual recidivism. However, the SSPI did not significantly predict sexual recidivism, and when controlling for static risk, only the VRS-SO Sexual Deviance factor significantly predicted this outcome. Modeling phallometric test scores continuously and trichotomously produced significant associations with sexual recidivism; however, only a trichotomous model with two levels remained predictive after controlling for static risk. The results are broadly supportive of measures of pedophilic interest and underscore the importance of appropriately modeling the latent structure of pedophilic interest.

<p>A significant number of male New Zealand high-risk violent offenders are released from prison onto parole each year. Many of these will also present with elevated psychopathic traits which have been hypothesised to cause significant difficulty in desisting from offending, often leading parolees to quickly recidivate or breach parole, and return to prison. Despite personality disorders having pervasive effects on functioning, other reintegration outcomes such as parolee experiences and reconviction risk on parole have previously been unlinked with personality disorders and even less so the specific components of psychopathy. Using an exploratory design, this study firstly investigated the relationships between the triarchic conceptualisation of psychopathy constructs of Disinhibition, Boldness, and Meanness individually with pre-release (Violence Risk Scale, Release Plan Quality, and RoC*RoI), and post-release (Dynamic Risk Assessment for Offender Re-entry, Probation Relationship Quality, Parole Experiences Measure, and recidivism) measures of reintegration outcomes. These measures were completed by a sample of high-risk violent offenders imminently before their release onto parole after serving custodial sentences of two years or more for a violent offence (pre-release), and at two months in the community (post-release). Secondly, the controversial question of whether boldness exacerbates or attenuates negative outcomes on parole over and above disinhibition or meanness was tested. Thirdly, relationships between psychopathy and recidivism mediated by reintegration outcome measures were examined. The triarchic scales were hypothesised to be relevant for reintegration outcomes, with poorer outcomes expected for disinhibition and meanness, and better outcomes expected for boldness. Further, boldness was expected to ameliorate negative outcomes when strongly present. Results indicated that the triarchic scales evinced differential relationships with reintegration outcomes, although boldness revealed non-significant outcomes in opposing directions from those hypothesised. Disinhibition and meanness evinced expected outcomes with reintegration outcome measures. An interaction effect was found between meanness and reconviction risk on parole at moderate and high levels of boldness; boldness potentiated the effect of meanness on reconviction risk on parole when meanness was already present. Finally, a significant partial mediation was revealed, where disinhibition and recidivism were mediated by parole experiences in three out of four recidivism outcomes. Implications for the theoretical and practical relevance of triarchic psychopathy for the reintegration of high-risk violent offenders, are discussed.</p>

Abstract. We examined the structural and predictive properties of the Violence Risk Scale-Sexual Offense (VRS-SO) version in an Austrian sample of N = 666 men incarcerated for sexual offenses; 353 of whom were followed up an average of 11 years post-release. Results of a confirmatory factor analysis of dynamic item scores supported a three-factor model (Sexual Deviance, Criminality, and Treatment Responsivity) consistent with prior research. VRS-SO static, dynamic, and total scores showed good properties of discrimination for sexual (area under the receiver operating curve [AUC] = .68–.80) and violent (AUC = .65–.68) recidivism, while the factor scores showed differential prediction of these outcomes. Calibration analyses demonstrated lower estimated rates of 5-year sexual reoffense associated with VRS-SO score bands in the present sample compared to observed rates from the normative sample, with closest correspondence observed for the highest risk band (E/O index = 1.01). Implications for the psychometric properties and application of the VRS-SO in international settings are discussed.
