This study aims to evaluate the impact of age at release on sexual recidivism rates and the predictive validity of six instruments (VRAG, SORAG, RRASOR, Static-99, Static -2002 and MnSOST-R) for 372 sex offenders divided in three sub-groups (child molesters, rapists and mixed offenders). In general, the results indicate that the relationship between age and recidivism present a quadratic form with increased rates of recidivism among young offenders, followed by a plateau and a decrease from the mid-forties. However, this relationship varies depending on the type of sex offenders. The average scores for the instruments decrease gradually as the offenders would advance in age, while the predictive validity of these tools is not influenced by the offenders’ age. However, after an adjustment of the instruments scores depending on the offenders types, the results suggest that the instruments are slightly better for older offenders. © 2016, Polymedia Meichtry SA.

This article explores new stimulus materials for use with penile plethysmography (PPG) assessments. First, this paper presents a pilot study where undergraduate students rated virtual characters (male and female) on perceived age. In addition, the materials developed are unique in that they depict the characters exhibiting varying affective dispositions, including neutral, fearful, sad, joyful, and seductive. Participants in the first study were also asked to identify the affective disposition of the virtual characters, and results suggest that affective disposition was largely perceived as intended, especially in terms of identifying the general emotional valence of the affective dispositions (i.e., positive versus negative). In a second pilot study, we used the computer-generated images to measure sexual arousal responses in a group of non-deviant males recruited in the community. Responses measured through penile plethysmography suggest participants responded to the stimuli as expected, as the greatest amount of sexual arousal was recorded when participants were shown the adult female character. In addition, participants responded with significant arousal only when the adult female character was depicted as sexually open (joyful or seductive), rather than sexually closed or neutral. Results suggest these materials may discriminate sexual interests if applied within clinical forensic assessment of sex offenders. © 2014 by the Sex Information and Education Council of Canada.},
