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.},

However, few data are available on patients, or on the effectiveness of different scenarios in inducing relaxation. This pilot study aims to compare the effectiveness of three relaxation techniques—preselected IVR (IVR-PS), preferred IVR (i.e. chosen by the participant from different alternatives—IVR-PR), and narrative alone (CTR)—in reducing physiological and psychological stress in 16 pulmonary arterial hypertension (PAH) female patients (N = 16, average age: 46 ± 10.66 years; average education: 13.31 ± 3.8 years; mean duration of illness: 8.56 ± 5.24 years) following an acute stress. Methods: Patients performed a mental stress test followed by three different relaxation sessions presented in a randomized order on three separate occasions. Self-perceived stress, level of relaxation, and heart rate (HR) were monitored during the sessions. Participants' ratings of their experiences were also collected. Results: The results indicated that the three relaxation methods were equally effective in reducing perceived stress induced by acute stress and in lowering HR. However, greater cognitive activation was reported in the two IVR conditions compared with the narrative condition. Conclusions: This is the first study to show evidence of the impact of IVR on a rare population. Despite the lack of significant differences between the two IVR and narrative-alone conditions in physiological and subjective relaxation, more than half of the participants expressed a subjective preference for the virtual experience, especially for the preferred one. © 2026 The Author(s).

However, few data are available on patients, or on the effectiveness of different scenarios in inducing relaxation. This pilot study aims to compare the effectiveness of three relaxation techniques—preselected IVR (IVR-PS), preferred IVR (i.e. chosen by the participant from different alternatives—IVR-PR), and narrative alone (CTR)—in reducing physiological and psychological stress in 16 pulmonary arterial hypertension (PAH) female patients (N = 16, average age: 46 ± 10.66 years; average education: 13.31 ± 3.8 years; mean duration of illness: 8.56 ± 5.24 years) following an acute stress. Methods: Patients performed a mental stress test followed by three different relaxation sessions presented in a randomized order on three separate occasions. Self-perceived stress, level of relaxation, and heart rate (HR) were monitored during the sessions. Participants' ratings of their experiences were also collected. Results: The results indicated that the three relaxation methods were equally effective in reducing perceived stress induced by acute stress and in lowering HR. However, greater cognitive activation was reported in the two IVR conditions compared with the narrative condition. Conclusions: This is the first study to show evidence of the impact of IVR on a rare population. Despite the lack of significant differences between the two IVR and narrative-alone conditions in physiological and subjective relaxation, more than half of the participants expressed a subjective preference for the virtual experience, especially for the preferred one. © 2026 The Author(s).

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.

Virtual reality (VR) has emerged as a promising tool for enhancing psychological interventions, but no comprehensive review has specifically focused on VR-based studies addressing BI disturbances in this population. Methods: This comprehensive review examined studies utilizing VR for the assessment and treatment of BI disturbances in individuals with obesity. Twelve studies met the inclusion criteria. Results: Studies were categorized into three groups: (i) VR in psychological interventions for individuals with obesity, (ii) VR interventions following metabolic and bariatric surgery, and (iii) VR-based full-body illusion experiments. The primary clinical application was experiential cognitive therapy, which demonstrated greater efficacy in reducing negative BI compared with standard cognitive behavioral therapy and other treatments. Studies involving post-metabolic and bariatric surgery adults also supported VR's efficacy in reducing BI dissatisfaction, though long-term benefits were inconsistent. Full-body illusion experiments suggested that VR can help modify distorted body perceptions. However, most studies were conducted by the same research group, focused exclusively on women, and were limited to specific geographical regions, primarily Italy. Conclusion: While preliminary results suggest that VR is a promising tool for treating BI disturbances in individuals with obesity, the field remains under-researched. Notably, no studies have explored VR's potential as an assessment tool in this population. Future studies should include more diverse populations, investigate long-term outcomes, and explore potential barriers to clinical implementation. © 2025 The Author(s).
