Identification des indices comportementaux reliés à la présence d'intérêts sexuels déviants chez les agresseurs sexuels d’enfants
Revisions proposed for the pedophilic disorder (DSM-5; APA, 2013) included a criterion based on a minimum victim count to diagnose pedophilia when child molesters do not acknowledge having sexual attraction towards children, and phallometric evaluation of their sexual interests is not available or invalid. It was also proposed to divide the diagnostic with subtypes based on the preferred age category or the victims’ age: pedophilic (10 year-olds and younger), hebephilic (11-14 year-olds), or pedohebephilic (both). These revisions generated controversies among researchers and clinicians, and they were not adopted due to the paucity of empirical evidence supporting these propositions. This doctoral thesis aims to answer the main questions that were raised: 1) What indicators should be used when assessing deviant sexual interests among intrafamilial and extrafamilial child molesters respectively?; 2) Are the number of sexual interactions and the period duration of the offenses on the same victim associated with sexual deviance? 3) Do early pubescent child molesters have deviant sexual interests? The first article is a commentary on the DSM-5 outlining the thesis and presenting the preliminary results of the two following articles. The second article aims to answer the first two questions. Intrafamilial child molesters (n = 76) and extrafamilial child molesters (n = 93) are compared on their victim count, victims’ age and gender, the number of sexual interactions and the period duration of the offenses on the same victim, and their sexual interests acknowledged or measured with penile plethysmography. Associations between these indicators and deviant sexual interests are assessed for both groups. The results suggest that: 1) different indicators of deviant sexual interests should be used according to the offenders’ group; 2) repeated sexual interactions on a long period on the same victim suggest sexual deviance among intrafamilial offenders, while there is no association between these variables among extrafamilial offenders. This research is a first step towards using the number of sexual interactions and the period duration of the offenses on the same victim when assessing sexual deviance among child molesters. iv The third article aims to answer the last question. Child molesters grouped according to their victims' age category, pedophilic (n = 75), hebephilic (n = 44), and pedohebephilic (n = 49), were compared on different variables: victim count, victims' gender, criminal history, and sexual interests measured with penile plethysmography and acknowledged. The results show deviant sexual interests in the same proportions among the three groups. As for the other variables, the pedophilic and hebephilic groups do not differ much, but they both differ from the pedohebephilic group. The results highlight the overlap between sexual attraction to prepubescent and attraction to early pubescent children, and support their inclusion in the same diagnostic.
