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.

This article addresses the intra- and extra-familial pathways of child molestation. The data presented show preliminary evidence that the difference between the intra- and extra-familial routes can be explained by schizoid and avoidant (intra-familial) and antisocial and passive-aggressive (extra-familial) personality structures. This study also reveals that the amount of warmth and autonomy received during childhood is associated with both intra- and extra-familial child-molesting behaviour. These findings contribute to a further explanation of this deviant sexual conduct and to the development and differentiation of the treatment of child molesters.

In this paper we present a clinical model for the treatment of personality disordered sexual offenders. The model is based on the theoretical assumption that cognitive distortions emerge from more general explanatory theories. It seems that the pathways of offending processes that are characterized by positive or negative affects can be found in all treated sex offenders regardless of their motivation. We assume that these pathways are activated by cognitive distortions that illustrate the underlying general explanatory theory held by the offender and that these distortions are typical for overall daily interpersonal behavior of the offender. This means that, as predicted by our clinical model in the case of offenders with a personality disorder, the type of explanatory cognition that is underlying their sexual offenses is the same as the one that is underlying their general explanatory theories. We will describe the clinical model and the treatment program used at Forensic Psychiatric Hospital Center Veldzicht with a review of our experiences.
