Résumé
Un large éventail d’instruments s’offre aux cliniciens pour évaluer le risque que posent les délinquants sexuels. La présente étude vise à comparer la validité prédictive de huit instruments (VRAG, SORAG, RRASOR, Statique-99, Statique-2002, RM2000, MnSOST–R et SVR-20) et un outil de référence (PCL-R) selon quatre types de récidive (nuisance sexuelle, récidive sexuelle, récidive violente non sexuelle et récidive non violente et non sexuelle) et pour trois groupes d’agresseurs sexuels. Les résultats indiquent que ces outils ont une validité prédictive marginale à modeste en ce qui concerne la récidive sexuelle. Cependant, une étude plus détaillée en fonction du type d’agresseurs indique une plus grande efficacité de ces instruments pour la récidive sexuelle chez les agresseurs d’enfants et pour la récidive non sexuelle chez les agresseurs de femmes. Les outils actuariels ne permettent de prédire aucune forme de récidive chez les agresseurs mixtes.

Abstract
This study compares the predictive accuracy of eight commonly used risk assessment instruments (the VRAG, the SORAG, the RRASOR, the Static-99, the Static-2002, the Risk Matrix 2000, the MnSOST–R and the SVR-20) and the PCL–R. Four types of recidivism were used (nuisance, sexual, nonsexual victim-involved and nonsexual victimless) and offenders were divided into three subgroups (rapists, child molesters and mixed offenders). Results indicate that instruments showed marginal to modest predictive accuracy for sexual recidivism. However, when we take account of the subgroups, the predictive accuracy for sexual recidivism was higher with child molesters and for non-sexual recidivism with rapists. Most instruments showed predictions no better than chance for mixed offenders and for predicting non-contact sexual reoffending.

Resumen
En la actualidad, se dispone de una amplia gama de herramientas para evaluar el riesgo de reincidencia de los delincuentes sexuales. El presente estudio compara la validez predictiva de ocho métodos (VRAG, SORAG, RRASOR, Static-99, Static-2002, RM2000, MnSOST-R y SVR-20) y un método de referencia (PCL-R) que evalúa cuatro tipos de reincidencia (reincidencia sexual violenta, reincidencia sexual, reincidencia violenta no sexual y reincidencia no violenta y no sexual) para tres grupos de agresores sexuales. Los resultados indican que estos métodos tienen una validez predictiva que va de marginal a modesta en lo que respecta a la reincidencia sexual. Sin embargo, un estudio más detallado en función del tipo de agresores indica una mayor eficacia de estos métodos para evaluar la probabilidad de reincidencia sexual en el caso de agresores de menores y la reincidencia no sexual de los agresores de mujeres. Los instrumentos estadísticos no permiten predecir ninguna forma de reincidencia en el grupo de los agresores mixtos.
