ABSTRACT
The aim of this study was to investigate the predictors of deviant sexual preferences in sexual aggressors of women and sexual aggressors of children. A total of 85 sexual aggressors of women and 81 sexual aggressors of children were included in this study. All subjects were imprisoned in a penitentiary, permitting assessment of their correctional risk level and their treatment needs. Assessment was carried out at the institution and consisted of the following categories : 1) personal history (sexuality, relationship, etc.); 2) family history (victimization, etc.); 3) modus operandi characteristics (premeditation, strategy to carry out the offense, etc.) ; 4) victim characteristics (presence of criteria to select the victim, gender, familiarity between the aggressor and the victim, etc.) ; 5) attitudes towards his crime and cognitive distortions. Moreover, sexual preferences were assessed phallometrically. Using logistic regression analysis, our results showed different predictors of deviant sexual preferences in sexual aggressors of women and sexual aggressors of children. Moreover, the predictors identified through the above method allowed to correctly classify more than 80 % of subjects according to whether they have deviant sexual preferences or not, in both types of sexual aggressor (sexual aggressors of women; sexual aggressors of children). These results will be discussed according to the theories of sexual aggression.
