Increasing Valid Profiles in Phallometric Assessment of Sex Offenders with Child Victims: Combining the Strengths of Audio Stimuli and Synthetic Characters

Virtual Reality Could Help Assess Sexual Aversion Disorder

Virtual reality (VR) may improve our understanding of sexual dysfunctions' manifestations, although research in this area remains limited. This study assessed the potential use of a VR Behavior Avoidance Test (VR-BAT) as a tool for examining the clinical features of Sexual Aversion Disorder (SAD): the experience of fear, disgust, and avoidance when facing sexual cues/contexts. A sample of 55 adults (≥ 18y) with (n = 27) and without SAD (n = 28) completed a self-report measure of sexual avoidance. Their anxiety, disgust, electrodermal activity, heart rate, and visual and behavioral avoidance were then examined during two VR-BATs involving sexual or non-sexual stimuli. Mixed repeated measures ANOVAs, t-tests, and correlational analyses were performed. Results showed that individuals in the SAD group reported greater anxiety and disgust compared to their non-SAD counterparts during the sexual stimuli condition. Sexual avoidance scores were largely positively related to anxiety and disgust during the VR sexual condition, and moderately negatively related to the time spent touching the virtual character's genitals. This study is important given the prevalence of sexual difficulties, such as SAD, and the new research avenues offered by emerging technologies, like VR.

Virtual Reality and Sex Therapy: Future Directions for Clinical Research

Rapidly growing new technologies are revolutionizing the field of mental health, in terms of both understanding and treating mental disorders. Among these, virtual reality (VR) is a powerful tool providing clients with new learning experiences benefiting their psychological well-being. This article offers an overview of the current literature on VR in psychotherapy, highlighting its relevance to sexual dysfunction (SD) treatment.A literature review of PubMed and Google Scholar databases was used to provide a description of the theoretical frameworks and clinical indications associated with VR use in psychotherapy and SD treatment. The effectiveness of VR exposure-based therapy has been empirically validated for several mental disorders, notably anxiety disorders. The emerging combined use of VR and mindfulness tends to focus on chronic pain treatment. Experimental research examining the use of immersive technologies in the treatment of SDs is lacking.Given the shortcomings of conventional SD treatments, exploring and developing specialized VR interventions may prove beneficial. VR offers promising avenues in sex therapy, particularly for the treatment of genital pain disorders or SDs in which anxiety plays a significant etiological role.

Are There Any Biomarkers for Pedophilia and Sexual Child Abuse? A Review

The use of biomarkers in medicine is a common and valuable approach in several clinical fields. Understanding the relationship between measurable biological processes and clinical outcomes not only is indispensable in the face of understanding physiological processes in healthy as well as in diseased organisms but also for understanding and evaluating treatment effects. Therefore, also in the context of forensic psychiatry, biomarkers and their potentially beneficial effects are of growing interest. The objective of this review is to examine if there are biomarkers that may serve as a tool to support diagnostic process, treatment evaluation, and risk assessment of pedophilic individuals and child sexual offenders. In the first part, we present an overview of the current neurobiological, as well as physiological and psychophysiological approaches to characterize pedophilia and child sexual offending. Secondly, we discuss and evaluate the impact of these approaches on the development of biomarkers for diagnosis, therapy, and risk assessment in pedophilic subjects and child sexual offenders. We conclude that a lot of research has already enhanced our neurobiological knowledge about pedophilia and child sexual offending. Although there surely exist promising parameters and approaches, in our view currently none of these is ready yet to serve as a clinically applicable diagnostic, response, or predictive biomarker for pedophilia and child sexual offending. Therefore, further work remains to be done. The development of a composite diagnostic biomarker to assess deviant sexual interest, combining several measures like functional magnetic resonance imaging, electroencephalogram, eye tracking, and behavioral approaches seems to be most promising. A valid and reliable measurement of deviant sexual interest, insensitive to manipulations could significantly support clinical diagnostic process. Similarly, regarding therapy evaluation and risk assessment, a composite biomarker to assess inhibitory control functions seems to be promising. Furthermore, the application of the Research Domain Criteria-approach, a new approach for investigating and classifying mental disorders, offers the possibility to take research to a new level.
