abstract = {Purpose Speaking in class is challenging for students who stutter. Cognitive-behavioral therapy (CBT) with exposure in virtual reality (VR) emerges as a promising intervention for treating speaking anxiety in pediatric populations. This pilot study tested if real-time avatar-based VR can elicit anxiety responses while remaining acceptable to youth who stutter. Method Twelve students who stutter (aged 9–18) were randomly assigned to a single training session conducted either (1) in VR with a realistic avatar controlled live by their SLP, or (2) in role-play with their SLP, before facing a real actor. We assessed system acceptability, anxiety levels and perceived self-efficacy. Results The VR system was well accepted and elicited physiological arousal comparable to real-life interactions. Although participants reported experiencing less anxiety during VR, skin conductance level showed higher arousal; suggesting a divergence between the subjective report and physiological response. Finally, one training session (either in VR or with the SLP) did not produce gains in self-efficacy or decrease in anxiety related to the final real-actor conversation. Conclusion This study demonstrates evidence that the potential use of immersive VR could represent an acceptable and viable complementary strategy for SLP treatment, that could control exposure parameters while evoking physiological responses similar to real-life contexts. The differences between subjective and physiological measures suggest that VR is inducing anxiety responses differently than it was perceived. Further research could investigate the use of VR as anxiety interventions for students who stutter and should be explored across multi-session studies to understand their therapeutic effect. © 2026 The Authors.},

abstract = {Cognitive-behavioral therapy (CBT) with exposure and response prevention (ERP) is widely regarded as the gold-standard psychological treatment for obsessive–compulsive disorder (OCD). Inference-based cognitive behavioral therapy (I-CBT) represents a distinct cognitive approach that targets inferential confusion, defined as a reasoning process whereby imagined possibilities are treated as reflecting reality, without relying on deliberate exposure. The present study reports further mechanism-focused analyses from a previously published multicenter randomized controlled trial (Aardema et al., 2022; ClinicalTrials.gov Identifier: NCT01794156) comparing CBT with ERP, I-CBT, and mindfulness-based stress reduction (MBSR) for OCD. A total of 111 participants with a primary diagnosis of OCD were randomized to one of three treatment conditions. Across treatments, therapy was associated with significant reductions in inferential confusion and obsessive belief domains, whereas dispositional mindfulness did not show significant change. At the bivariate level, residualized changes in inferential confusion, obsessive belief domains, and mindfulness were associated with reductions in OCD symptoms. However, when examined concurrently using mixed-effects models, only reductions in inferential confusion accounted for unique symptom improvement over time. This association was consistent across modalities and remained robust after controlling for concurrent anxiety and depression. Sensitivity analyses indicated that psychotropic medication use did not account for this association; controlling for medication strengthened the independent contribution of inferential confusion (partial η2 ≈ .29). These findings indicate that inferential confusion was independently associated with symptom improvement in OCD across therapeutic approaches. © 2026 Elsevier Ltd},

The study was motivated by a recent publication mentioning that potential aversive outcomes of being judged in virtual reality and by virtual characters have no objective negative consequence in daily life. A sample of 51 adults completed outcome and cognitive mechanism measures at a pretreatment, after 14 weeks of treatment or being on a waiting list, and at a 6-month follow-up. Results demonstrate that conducting exposure in virtual reality led to reductions in dysfunctional beliefs about the perceived consequences of feared social threats, about the likelihood of these feared threats occurring, as well as an increase in perceived self-efficacy to face social situations. These changes were statistically significant when compared to the waiting list condition, remained stable at the 6-month follow-up, and were no less important than when exposure was conducted in vivo. All predictors significantly correlated (p < .001) with the two measures of treatment outcome. Further analyses of cognitive mechanism measures predicting treatment outcomes revealed that, when controlling for shared variance, changes in perceived likelihood and in self-efficacy contributed significantly to patients’ improvement, whereas the role of perceived consequences was only a predictor of self-efficacy. © 2025, Interactive Media Institute.

Participants completed measures of working alliance and telepresence after three psychotherapy sessions. They also completed measures of treatment outcome and dysfunctional beliefs (cognitive change) specific to PDA and GAD at pretreatment and posttreatment. Results revealed that telepresence at the fifth session moderated the relationship between the working alliance at the first and fifth sessions.
