abstract = {Penile plethysmography (PPG) is a measure of sexual interests that relies heavily on the stimuli it uses to generate valid results. Ethical considerations surrounding the use of real images in PPG have further limited the content admissible for these stimuli. To palliate this limitation, the current study aimed to combine audio and visual stimuli by incorporating computer-generated characters to create new stimuli capable of accurately classifying sex offenders with child victims, while also increasing the number of valid profiles. Three modalities (audio, visual, and audiovisual) were compared using two groups (15 sex offenders with child victims and 15 non-offenders). Both the new visual and audiovisual stimuli resulted in a 13% increase in the number of valid profiles at 2.5 mm, when compared to the standard audio stimuli. Furthermore, the new audiovisual stimuli generated a 34% increase in penile responses. All three modalities were able to discriminate between the two groups by their responses to the adult and child stimuli. Lastly, sexual interest indices for all three modalities could accurately classify participants in their appropriate groups, as demonstrated by ROC curve analysis (i.e., audio AUC = .81, 95% CI [.60, 1.00]; visual AUC = .84, 95% CI [.66, 1.00], and audiovisual AUC = .83, 95% CI [.63, 1.00]). Results suggest that computer-generated characters allow accurate discrimination of sex offenders with child victims and can be added to already validated stimuli to increase the number of valid profiles. The implications of audiovisual stimuli using computer-generated characters and their possible use in PPG evaluations are also discussed. © 2017, Springer Science+Business Media, LLC.},

abstract = {Virtual reality has shown promising results in the treatment of posttraumatic stress disorder (PTSD) for some traumatic experiences, but sexual assault has been understudied. One important question to address is the relevance and safety of a virtual environment (VE) allowing patients to be progressively exposed to a sexual assault scenario. The aim of this study was to validate such a VE. Thirty women (victims and nonvictims of sexual assault) were randomly assigned in a counter-balanced order to 2 immersions in a virtual bar: a control scenario where the encounter with the aggressor does not lead to sexual assault and an experimental scenario where the participant is assaulted. Immersions were conducted in a fully immersive 6-wall system. Questionnaires were administered and psychophysiological measures were recorded. No adverse events were reported during or after the immersions. Repeated-measures analyses of covariance revealed a significant time effect and significantly more anxiety (Cohen's f = 0.41, large effect size) and negative affect (Cohen's f = 0.35, medium effect size) in the experimental scenario than in the control condition. Given the safety of the scenario and its potential to induce emotions, it can be further tested to document its usefulness with sexual assault victims who suffer from PTSD.
