abstract = {The proposed study aims at expanding results from a previous study on mechanisms of change after exposure in virtual reality (VR) and documenting the impact of adding tactile and haptic feedback. It was predicted that change in the severity of spider phobia according to the Fear of Spiders Questionnaire (FSQ) would be significantly predicted by change in dysfunctional beliefs toward spiders and self-efficacy, over and above the variance explained by a physiological measure of fear during exposure (heart rate) and presence during the immersion. Participants (N = 59) were randomly assigned to the presentation of visual stimuli only, visual plus tactile stimuli, or visual, tactile plus haptic feedback stimuli. A standard multiple regression was conducted to predict change on the FSQ using the following predictors: beliefs about spiders, beliefs about one's own behavior when facing spiders, perceived self-efficacy, disgust, presence, and heart rate. Only changes in beliefs about spiders and in perceived self-efficacy significantly predicted the reduction in fear of spiders. This result enhances our understanding of the mechanisms involved in exposure conducted in VR. Analyses of variance also show that participants reported statistically significant changes in their clinical condition, with little added value to the addition of tactile and haptic feedback. The advantages of tactile and haptic stimulation are questioned, at least in the context of only one brief exposure session and the equipment used. © 2019, Mary Ann Liebert, Inc.},

abstract = {The use of virtual reality to treat anxiety disorders in adults is gaining popularity and its efficacy is supported by numerous outcome studies. Similar research for children is lagging behind. The outcome studies on the use of virtual reality to treat anxiety disorders in children currently address only specific phobias, and all of the available trials are reviewed in this article. Despite the limited number of studies, results are very encouraging for the treatment of school and spider phobias. A study with adolescents suggests that, at least for social anxiety, exposure stimuli would be more effective if they were developed specifically for younger populations. Virtual reality may not increase children's motivation towards therapy unless their fearful apprehension is addressed before initiating the treatment. © 2011 Expert Reviews Ltd.},

abstract = {The present study compared the efficacy of virtual reality (VR) in virtuo exposure and in vivo exposure in the treatment of spider phobia. Two treatment conditions were compared to a waiting-list condition. A 3-month follow-up evaluation was conducted in order to assess the durability of the treatment effects. Participants were randomly assigned to the treatment groups. A total of 16 participants received the in virtuo treatment, and 16 received the in vivo treatment. The waiting-list condition included 11 participants. Participants received eight 1.5-hour treatment sessions. Efficacy was measured with the Fear of Spiders Questionnaire, the Spider Beliefs Questionnaire (SBQ-F), and a Behavioral Avoidance Test (BAT). In addition, a clinician administered the Structured Interview for DSM-IV to assess DSM-IV's criteria for specific phobia and severity. Clinical and statistically significant improvements were found for both groups. Differences in treatment groups were found on one of five measures of fear: greater improvement on the SBQ-F beliefs subscale was associated with in vivo exposure.

abstract = {Many studies have assessed virtual reality exposures efficacy, but very few examined its treatment processes. The addition of objective measures of arousal and information processing mechanisms would be a valuable contribution in order to provide a more complete and detailed picture. The goal of this study was to better document the cognitive mechanisms associated with therapeutic change after an in virtuo exposure treatment. Twenty-eight adults suffering from arachnophobia were assessed and received an exposure-based treatment using virtual reality. General outcome and specific processes measures included a battery of standardized questionnaires, a pictorial emotional Stroop task, a Behavioral Avoidance Test, and a measure of participants' cardiac response while they looked at a live tarantula. The analyses showed that changes in perceived self-efficacy and dysfunctional beliefs were the best predictors of change in general outcome and cardiac response; change in dysfunctional beliefs were the best predictor of change in behavioral avoidance. These innovative results provide a very detailed and organized picture of the complex cognitive mechanisms involved in therapeutic change following in virtuo exposure for arachnophobia. © 2009 Mary Ann Liebert, Inc.},

abstract = {Many outcome studies have been conducted to assess the efficacy of virtual reality in the treatment of specific phobias. However, most studies used self-report data. The addition of objective measures of arousal and information processing mechanisms would be a valuable contribution in order to validate the usefulness of virtual reality in the treatment of anxiety disorders. The goal of this study was to document the impact of virtual reality exposure (VRE) on cardiac response and automatic processing of threatening stimuli. Twenty-eight adults suffering from arachnophobia were assessed and received an exposure-based treatment using virtual reality. General outcome and specific processes measures included a battery of standardized questionnaires, a pictorial emotional Stroop task, a behavioral avoidance test and a measure of participants' inter-beat intervals (IBI) while they were looking at a live tarantula. Assessment was conducted before and after treatment. Repeated measures ANOVAs revealed that therapy had a positive impact on questionnaire data, as well as on the behavioral avoidance test. Analyses made on the pictorial Stroop task showed that information processing of spider-related stimuli changed after treatment, which also indicates therapeutic success. Psychophysiological data also showed a positive change after treatment, suggesting a decrease in anxiety. In sum, VRE led to significant therapeutic improvements on objective measures as well as on self-report instruments. © 2005 Springer Science+Business Media, Inc.},

abstract = {Tracking behavior with a virtual spider and a neutral target is compared in fearful and nonfearful subjects. Head-tracking in virtual environments appears to be a scale-free behavior with long-range fractal-like patterns. Moreover, these fractal patterns change according to what the target affords the tracker and the level of behavioral avoidance manifested by the subjects. Results are interpreted in terms of ecological psychology and nonlinear dynamics, and implications for virtual reality (VR) psychology are outlined.},
