abstract = {Background: Social anxiety disorder (SAD) has a high prevalence and an early onset. It often persists well into adulthood, turning into a chronic disorder. Cognitive behavioral therapy (CBT) is effective in treating SAD, but real-life exposure conducted as part of CBT is often costly and time-consuming, and imaginary exposure might lack realism and intensity. Virtual reality (VR)-based exposure using 360° video offers a promising way to deliver exposure therapy. Objective: To develop a complete psychotherapeutic treatment program including CBT with VR-based exposure using 360° videos (CBT-ExpVR) for adult patients with SAD and to test the treatment effect using the Social Interaction Anxiety Scale (SIAS) as the primary outcome. Methods: This three-arm randomized controlled trial involved 51 participants who were recruited through self-referral. The interventions took place at Center for Digital Psychiatry in Denmark. Participants were randomized via computer program to CBT-ExpVR, CBT with in vivo exposure (CBT-Exp), or an active control group offered VR relaxation (RlxVR). Afterwards, participants assigned to RlxVR were re-randomized to one of the two CBT interventions. Allocation was not blinded. Results: Intention-to-treat analysis showed that participants receiving CBT-ExpVR reported significantly fewer symptoms of social anxiety at post-treatment compared to pre-treatment, β = −14.89, 95% CI (−18.64, −11.14), p < 0.0001. At post-treatment, no difference in treatment effect was found between CBT-ExpVR and CBT-Exp, β = 3.643, 95% CI (−1.727, 9.013)},

Measures of cognitive mechanisms had been collected but never analyzed. 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.

abstract = {Background: Social anxiety disorder (SAD) is a long-term and overwhelming fear of social situations that can affect work, school, and other daily activities. Although cognitive behavioral therapy is effective, few seek treatment, and many who do start often drop out. This may be due to the component of exposure inherent to cognitive behavioral therapy, where the patient confronts feared stimuli outside the therapist’s office, which they otherwise try to avoid. As an alternative, research has explored the effectiveness of virtual reality (VR)–based exposure therapy with promising results. However, few studies have investigated the feasibility of VR tools using mixed methodologies before assessing their efficacy. Objective: This study aims to assess the usability, feasibility, and presence of four 360° virtual environments and whether these were able to evoke anxiety in patients with SAD. Methods: A total of 10 adult participants with SAD and 10 healthy controls were recruited for 1 experimental session (age range 21-32 y; 12/20, 60% male participants). Questionnaire and interview data were collected and analyzed. A mixed methods triangulation design was applied to analyze and compare the data. Results: Participants with SAD experienced increased anxiety when exposed to VR, and environments were considered relevant and useful as an exposure tool. Participants with SAD reported significantly higher average anxiety levels (P=.01) and peak anxiety levels (P=.01) compared with controls during exposure; however, significant differences in anxiety when accounting for baseline anxiety levels were only found in 2 of 4 environments (P=.01},
