A five-factor model perspective on psychopathy and comorbid Axis-II disorders in a forensic-psychiatric sample

The validity of DSM-IV predictions [Widiger, T.A., Trull, T.J., Clarkin, J.F., Sanderson, C.j., & Costa, P. T., (2002). A description of the DSM-IV personality disorders with the five-factor model of personality. In Costa, R T. & Widiger, I A. (Eds.), Personality disorders and the five-factor model of personality (2nd ed.). Washington DC: American Psychological Association] concerning Antisocial Personality Disorder and the validity of the hypothesized associations between the Five-Factor Model and psychopathy were examined in 48 male forensic-psychiatric patients. Prevalence of psychopathy and comorbid personality pathology was also investigated, as well as the convergent validity of two Dutch personality disorder inventories. Patients provided self-descriptions on the NEO-PI-R [Costa, R T., & McCrae, R.R., (1992b). Professional Manual: Revised NEO Personality Inventory (NEO-PI-R) and NEO Five-Factor-inventory (NEO-FFI). Odessa, FL: Psychological Assessment Resources], and were administered the VKP [Duijsens. I.J., Haringsma, R., & EurelingsBontekoe, E.H.M., (1999). Handleiding VKP (Vragenlijst voor kenmerken van de persoonlijkheid). Gebaseerd op DSM-IV en ICD-10. Leiderdorp: Datec] and the ADP-IV [Schotte, C.K.W., & De Doncker, D. A. M., (1994). ADP-IV Questionnaire. Antwerp Belgium: University Hospital Antwerp] to assess personality pathology. Psychopathy was assessed using Hare's Psychopathy Checklist-Revised (PCL-R; [Hare, R. D., (1990). The Hare Psychopathy Checklist Revised Manual. Toronto: Multi-Health Systems]) based on a semi-structured interview and file records of psychiatric and psychological evaluations and criminal history. Results underscored the validity of the FFM Antisocial PD associations, but the hypothesized correlations between the FFM and Psychopathy were less supported. Results supported the convergent validity of the ADP-IV and the VI(P, both at the dimensional and categorical level. Around 55% met the diagnostic threshold of psychopathy, and Antisocial PD was the most prevalent disorder in the psychopathic group, consistent with previous research. Sizeable personality comorbidity was also observed

Sexual History Disclosure Polygraph Examinations With Cybercrime Offences A First Dutch Explorative Study

This article presents the first study on post-conviction polygraphy in the Netherlands. Importantly, it exclusively focuses on cybercrime offenders. The study is designed to systematically address the different child sexual behaviours exhibited by 25 participants who are in treatment for possessing child abuse images. The results indicate that post-conviction polygraphy can provide additional data to inform the development of theory in this area and contribute to the treatment, supervision, and more effective containment of offending behaviour and the reduction of future victimization

Victim ranking among sex offenders

A previous exploratory study of the Child Molester Empathy Measure (CMEM) focused on the difference between offenders' normal level of general empathy and the way in which a sample of Dutch offenders viewed their own victims. The authors found that, regardless of their level of general victim empathy, all offenders thought that their own victims were better off than the unknown victims of sexual offences. In order to study this ranking phenomenon more closely, the authors replicated the study procedure with Dutch and Australian offenders. The authors rated each offender's responses for three child victims on the CMEM on an n-dimensional column vector and compared these data with their answers to the same questions related to two adult victims. The results are presented in this paper.
