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.

abstract = {Numerous instruments are available to clinicians for evaluating sex offenders' reoffense risk. Although they have demonstrated effectiveness in predicting recidivism significantly better than unstructured clinical evaluation, little is known about their predictive accuracy in subgroups of sexual offenders or in the long term. This study was undertaken to evaluate the predictive accuracy of nine instruments (VRAG, SORAG, RRASOR, Static-99, Static-2002, RM2000, MnSOST-R, SVR-20, PCL-R) among three groups of sexual offenders across a 15-year follow-up period. The results indicate that these instruments yielded marginal to modest predictive accuracy for sexual recidivism. A more detailed study of aggressor subgroups indicated that in both the short and the long term, these instruments were more effective at predicting the sexual recidivism of child molesters and the violent and nonviolent recidivism of rapists. Finally, although mixed offenders sexually reoffend more often and more rapidly than do rapists or child molesters, firm conclusions cannot be drawn because of the small number of mixed offenders in the sample. © 2011 International Association for Correctional and Forensic Psychology.},
