Ask the Expert: Anxiety Disorders Virtual Reality Therapy

Extended-Reality Technologies: An Overview of Emerging Applications in Medical Education and Clinical Care.

Virtual reality (VR) has been investigated as amedium for exposure therapy of anxiety disorders for 20years. Various meta-analyses have provided convincing evidence of the therapeutic efficacy of exposure therapy in VR. In recent years VR technology and its applications have considerably improved. Therefore, the current state of the art of VR exposure therapy is presented. This article provides anarrative review of current research on VR exposure therapy for anxiety disorders and major directions of development in this area. After an almost exclusive focus on specific phobias in the early days, research on more complex anxiety disorders (particularly on social anxiety disorder) is increasing. In addition, VR has become established as an experimental method to probe psychopathological processes and to elucidate the mechanism of action of (VR) exposure therapy. There is still aneed for more research into VR exposure therapy, especially in complex anxiety disorders (e. g. panic disorder, agoraphobia and social anxiety disorder) and trauma-related disorders. Furthermore, VR has become established as aresearch tool. The rapid technological development gives reason to expect acontinuing increase in VR research, in clinical as well as basic research.

Computer-Based Social Anxiety Regulation in Virtual Reality Exposure Therapy

Psychotherapy, and particularly exposure therapy, has been proven to be an effective treatment for many anxiety disorders, including social and specific phobias, as well as posttraumatic stress disorders. Currently, exposures are underused and mostly delivered in vivo. Virtual reality exposure therapy (VRET) offers a more flexible delivery mechanism that has the potential to address some of the implementation barriers of in vivo exposures while retaining effectiveness. Yet, there is little evidence on how patients perceive different exposure therapy methods. This study aims to explore the perceptions of individuals with anxiety disorders toward in vivo and VRET. Our findings can inform therapists about the degree of patient interest in both methods while exploring the demand for VRET as an alternative and novel treatment approach. Web-based survey assessing the (1) interest in, (2) willingness to use, (3) comfort with, (4) enthusiasm toward, and (5) perceived effectiveness of exposure therapy when delivered in vivo and through VR. Participants included individuals with specific phobia, social phobia, posttraumatic stress disorder, or acute stress disorder or reaction. Participants were presented with educational videos about in vivo and VRET and asked to provide their perceptions quantitatively and qualitatively through a rated scale and free-text responses. In total, 184 surveys were completed and analyzed, in which 82% (n=151) of participants reported being willing to receive in vivo exposures and 90.2% (n=166) reported willingness to receive VRET. Participants reported higher interest in, comfort with, enthusiasm toward, and perceived effectiveness of VRET compared to in vivo. Most reported in vivo concerns were linked to (1) increased anxiety, (2) feelings of embarrassment or shame, and (3) exacerbation of current condition. Most reported VRET concerns were linked to (1) risk of side effects including increased anxiety, (2) efficacy uncertainty, and (3) health insurance coverage. The most frequently mentioned VRET benefits include (1) privacy, (2) safety, (3) the ability to control exposures, (4) comfort, (5) the absence of real-life consequences, (6) effectiveness, and (7) customizability to a wider variety of exposures. On average, our participants expressed positive perceptions toward exposure therapy, with slightly more positive perceptions of VRET over in vivo exposures. Despite valid personal concerns and some misconceptions, our findings emphasize that VRET provides an opportunity to get much-needed therapy to patients in ways that are more acceptable and less concerning.

Virtual reality (VR) as a digital technology has developed rapidly, becoming more realistic, portable, sensory and easier to navigate. Although studies have found VR to be effective for many clinical applications, patients and clinicians have described several barriers to the successful implementation of this technology. To remove barriers for implementation of VR in health care, a greater understanding is needed of how VR can integrate into clinical environments, particularly complex settings such as an intensive care unit. This study aimed to explore the perceived barriers and facilitators for the implementation of VR exposure therapy for intensive care patients and clinical staff. A qualitative study using an Interpretative Description approach was undertaken. Semi-structured focus groups were conducted with 13 participants: nine patients and four health care professionals. Focus groups explored barriers and facilitators of using virtual reality (VR) exposure therapy in intensive care. Thematic analysis was employed to produce codes and themes. In total, eight themes describing the perceived barriers and facilitators to implementing VR exposure therapy were identified. Four themes related to the perceived barriers of implementing VR exposure therapy in intensive care were identified: psychological, sensory, environmental and staff competency and confidence. There were a further four themes related to the perceived facilitators to the implementation of VR exposure therapy: staff training, patient capacity, orientation to technology and support during the intervention. This study identified novel barriers and facilitators that could be expected when implementing VR exposure therapy for patients' post-intensive care unit stay. The findings suggest that psychological barriers of fear and apprehension were expected to provoke patient avoidance of exposure therapy. Perceived barriers for staff focused on preparedness to deliver the VR exposure therapy and a lack of technological competence. Both patients and staff stated that a comprehensive induction, orientation and training could facilitate VR exposure therapy, improving engagement. This study has identified that with appropriate staff training, resources, and integration into current patient care pathways, VR exposure therapy may be a valuable intervention to support patient recovery following critical illness. Prior to undertaking VR exposure therapy, patients often need reassurance that side-effects can be managed, and that they can easily control their virtual exposure experience.

In virtual reality exposure therapy (VRET) for anxiety disorders, sense of presence in the virtual environment is considered the principal mechanism that enables anxiety to be felt. Existing studies on the relation between sense of presence and level of anxiety, however, have yielded mixed results on the correlation between the two. In this meta-analysis, we reviewed publications on VRET for anxiety that included self-reported presence and anxiety. The comprehensive search of the literature identified 33 publications with a total of 1196 participants. The correlation between self-reported sense of presence and anxiety was extracted and meta-analyzed. Potential moderators such as technology characteristics, sample characteristics including age, gender and clinical status, disorder characteristics and study design characteristics such as measurements were also examined. The random effects analysis showed a medium effect size for the correlation between sense of presence and anxiety (r = .28; 95% CI: 0.18–0.38). Moderation analyses revealed that the effect size of the correlation differed across different anxiety disorders, with a large effect size for fear of animals (r = .50; 95% CI: 0.30–0.66) and a no to small effect size for social anxiety disorder (r = .001; 95% CI: −0.19–0.19). Further, the correlation between anxiety and presence was stronger in studies with participants who met criteria for an anxiety disorder than in studies with a non-clinical population. Trackers with six degrees of freedom and displays with a larger field of view resulted in higher effect sizes, compared to trackers with three degrees of freedom and displays with a smaller field of view. In addition, no difference in effect size was found for the type of presence measurement and the type of anxiety measurement. This meta-analysis confirms the positive relation between sense of presence and anxiety and demonstrates that this relation can be affected by various moderating factors.

Maximizing the impact of virtual reality exposure therapy for anxiety disorders

Among military personnel who participated in combat, the prevalence of post-traumatic stress disorder ranges from 3 % to 11 %. Up to 40 % of patients with post-traumatic stress disorder may not respond to classical treatments such as pharmacotherapy or psychotherapy. Therefore, it is extremely important to develop neurobiological non-drug rehabilitation methods that will more accurately target the neural mechanisms of sensorimotor integration. In this regard, we consider it advisable to analyze whether exposure therapy in virtual reality will effectively address a wide range of symptoms in post-traumatic stress disorder. We conducted a search for articles on the Medline (PubMed) website up to and including March 3, 2025. The search bar was a query for (VR OR virtual reality) AND (PTSD OR post-traumatic stress disorder). We found 25 articles. After deleting the articles that did not meet the criteria, 7 articles remained. Patients with post-traumatic stress disorder report a high degree of immersion when using exposure therapy in virtual reality, and studies show that increased emotional engagement can improve treatment outcomes. Exposure therapy in virtual reality may be particularly useful in the treatment of resistant post-traumatic stress disorder, as it allows the patient to activate traumatic memory more intensively, which is necessary for the extinction of conditioned fear. Exposure therapy in virtual reality had a positive effect on a range of post-traumatic stress disorder symptoms in combat veterans, and all treatment outcomes persisted for 3, 6, and 12 months, although the clear cost advantage and clinical benefits of exposure therapy in virtual reality compared to traditional exposure therapy have not yet been demonstrated.

The emergence of technologies like Virtual Reality (VR) is revolutionizing psychological therapies. This paper provides a comprehensive review of research on the use of VR in therapy for psychological disorders. The review examines literature studying the applications of Virtual Reality Therapy (VRT) in disorders such as Post-traumatic Stress Disorder (PTSD), Social Anxiety Disorder (SAD), and Public Speaking Anxiety (PSA). It explores the therapeutic effects of VRT from three perspectives: enhanced realism in exposure therapy, improved accessibility and convenience, and control over the intensity of stimuli. Key findings indicate that VRT effectively alleviates symptoms such as anxiety and physiological stress in patients. The paper also addresses challenges and ethical considerations associated with VRT, including access to VR equipment and data privacy. It concludes by suggesting potential directions for future research, such as expanding VRT applications to more mental disorders and integrating high technologies like artificial intelligence to further explore VRT's potential.

In this study, we addressed the effect of stereoscopy on presence, anxiety, and cybersickness in a virtual public speaking world, and investigated the relationships between these three variables. Our results question the practical relevance of applying stereoscopy in head-mounted displays (HMDs) for virtual reality exposure therapy (VRET) in a virtual public speaking world. In VRET, feelings of presence improve the efficacy (B. K. Wiederhold & M. D. Wiederhold, 2005). There are reports of a relatively large group of dropouts during VRET at low levels of presence in the virtual environment (Krijn, Emmelkamp, Olafsson, & Biemond, 2004). Therefore, generating an adequate level of presence is essential for the success of VRET. In this study, 86 participants were recruited and they were immersed in the virtual public speaking world twice: once with stereoscopic rendering and once without stereoscopic rendering. The results showed that spatial presence was significantly improved by adding stereoscopy, but no difference for reported involvement or realism was found. The heart rate measurements also showed no difference between stereoscopic and nonstereoscopic viewing. Participants reported similar anxiety feelings about their talk and similar level of cybersickness in both viewing modes. Even though spatial presence was significantly improved, the size of statistical effect was relatively small. Our results therefore suggest that stereoscopic rendering may not be of practical importance for VRET in public speaking settings.

Is virtual reality always better than 2D videos? A head-to-head randomized controlled trial for fear of flying with long-term follow-up.

It is well documented that teachers experience a plethora of emotions in their work including anxiety. While most research has focused on anxiety in regard to curricular areas, teachers may also experience public speaking anxiety. Unlike curricular anxiety, public speaking anxiety permeates all aspects of a teacher’s work, thereby potentially exerting negative consequences for their own well-being and their students’ learning. This multi-method pre-post single-group pilot study aimed to explore sources of pre-service teachers’ public speaking anxiety and to test the utility of a virtual reality (VR) intervention to reduce public speaking and social appearance anxiety. Participants (n = 7) described three sources of public speaking anxiety: communication difficulties, expectations of others, and judgment of others. Participants delivered three lessons over a period of about 5 weeks to a VR classroom simulated by the Virtual Orator © program. There were 22 student avatars representing various genders and ethnicities. Avatars were programmed to be informal in their actions and generally friendly, but they could not interact with the participant. The results of paired-samples t-tests showed that public speaking and social appearance anxiety were significantly reduced following the VR intervention. Participants described the VR as realistic and useful for real life. We discuss the results from the perspective of the control-value theory of emotions with implications for teacher education programs.

Virtual reality exposure therapy for anxiety disorders: A meta-analysis

Virtual reality (VR) applications have been increasingly used in the clinical field. Its applications in psychotherapies is becoming widespread with researches. The use of VR in psychotherapy, specifically as an exposure therapy approach, is prominently used in the treatment of specific phobias, which is one of the most common clinical presentations. There is a substantial body of literature investigating the effectiveness of VR applications in the treatment of specific phobias. The purpose of this review is to introduce the virtual environment scenarios used in virtual reality exposure therapy (VRET) applications for various specific phobias. Keywords: specific phobias, cognitive behavioral therapy, virtual reality applications

A number of carefully controlled studies have documented the effectiveness of traditional imaginal exposure for the treatment of post-traumatic stress disorder (PTSD). Virtual reality (VR) exposure therapy is based on a similar logic but rather than self-generating imagery, patients wear a VR helmet and go into a three-dimensional (3-D) computer generated virtual world to help them gain access to their memory of the traumatic event. Recent preliminary research has shown that some patients who fail to respond to traditional therapy benefit from virtual reality exposure therapy, presumably because VR helps the patient become emotionally engaged while recollecting/recounting/re-interpreting/emotionally processing what happened during the traumatic event. The present paper presents a brief overview of a new VR World we developed to provide virtual reality therapy for terrorist bus bombing victims in Israel, and a brief description of our research protocol and measures (for details, see www.vrpain.com).
