Victim Age Polymorphism In Stranger Serial Sexual Offences

Victim age polymorphism describes a subset of serial sexual offenders who offend against victims from multiple age groups (Guay, Proulx, Cusson, & Ouimet, 2001). Research on victim age polymorphism is an important area of study as polymorphic offenders have been found to have high recidivism rates (Parent, Guay, & Knight, 2011). The current study provided an exploration of polymorphism in 72 sexual offenders who committed 361 stranger offences. Polymorphism occurred in 36% of offenders’ sexual offence series, with the majority of polymorphic offenders victimizing minors aged 11 to 14. In comparison to age specific offenders, polymorphic offenders were found to be a) younger at the start of their sexual offence series, b) more opportunistic, c) less concerned with victim characteristic, d) more likely to be antisocial, and e) a trend was observed that suggested they were more likely to show deviant arousal to rape. These results will be discussed within the contexts of Investigative and Forensic Psychology.

Autism spectrum disorder, bestiality and zoophilia: a systematic PRISMA review

Purpose There remains a lack of knowledge surrounding paraphilic or deviant arousal sexual behaviours in individuals with Autism spectrum disorder (ASD) (Kellaher, 2015). The purpose of this paper is to explore the literature for any empirical study, case study or discussion/review paper surrounding individuals with ASD and zoophilia or bestiality. Design/methodology/approach A systematic PRISMA review was conducted. Findings This systematic review highlighted only a small number of papers, which have looked at zoophilia or bestiality in individuals with ASD. Only one article was identified as being relevant in the present review, three further articles included a description of a case involving someone with ASD who engaged in zoophilia or bestiality and another paper, although not the focus of the study, found one person with Asperger’s disorder who had several paraphilias including olfactophilia, podophilia and zoophilia in a sample of 20 institutionalised, male adolescents and young adults with Autistic disorder and borderline/mild mental retardation. All the case studies clearly highlight some of the ASD symptomology that can contribute to engaging in bestiality or zoophilia. Practical implications It is important that individuals with ASD have access to appropriate and timely sex education and that parents are supported by healthcare professionals to engage with their children with ASD in such interactions across the autism spectrum irrespective of the parent’s expectations. Originality/value To the author’s knowledge, this is the first review of ASD in relation to bestiality and zoophilia.

Two Inventories for the Measurement of Psychopathology: Dimensions and Common Factorial Space on Millon's Clinical and Eysenck's General Personality Scales

A same-day administration of the Millon Clinical Multiaxial Inventory and the Eysenck Personality Questionnaire to 325 male and 531 female clients allowed study of the psychometric properties of both instruments. Clients scoring low on Eysencks' Psychoticism, Extraversion, Neuroticism, and the Lie scale significantly differed from their high-scoring peers on many mean scores for the 20 Millon scales. Midrange scorers on the four Eysenck scales differed from extreme scorers on some Millon scales. A principal axis factor analysis accounted for over 80% of the total variance by four roots, tentatively identified as (1) Deviant Arousal; (2) for women, Deviant Socializing, for men, Self-protective Delusions; (3) for women, Self-protective Aloofness, for men, Deviant Socializing; and (4) Unusual Perceptions of Self. A noteworthy finding was that the factorial space is shared by Millon's categorical (psychiatric) variables and Eysenck's empirico-psychological constructs. Reported findings supported our assumptions about the quantitative rather than qualitative structure of human psychopathology as measured by the Millon and Eysenck scales. Both inventories complement each other by having shown dissimilar sensitivities and discriminative powers. A replication of our findings is necessary before employing the Eysenck Personality Questionnaire as a screening instrument in clinical settings.
