Virtual reality compared with in vivo exposure in the treatment of social anxiety disorder: a three-arm randomised controlled trial

Clinicians' perspectives of immersive tools in clinical mental health settings: a systematic scoping review

BACKGROUND

Virtual Reality in mental health treatment has potential to address a wide spectrum of psychological and neurocognitive disorders. Despite the proven benefits, integration into clinical practice faces significant challenges. There is a critical need for research into clinicians' perceptions of virtual reality due to the gap between rapid technological advancements and their adoption in mental health services.

METHOD

A scoping review was conducted to comprehensively understand clinicians' perspectives on the application of immersive virtual reality technologies within mental health settings. 4 data bases were searched, from inception, with the search areas of clinicians', technology, perspectives and mental health. The scoping review followed the PRISMA-ScR checklist. All results were thematically analysed to identify and categorise themes with a focus on qualitative analyses of clinicians' experiences and perceptions of VR applications in therapeutic contexts.

RESULTS

17 articles were selected, encompassing a range of mental health settings. The findings indicate that the integration of VR in clinical environments is heavily influenced by clinicians' knowledge and experience, with unfamiliarity often leading to scepticism. Positive attitudes towards VR, bolstered by direct experience and training, were found to drive acceptance, as clinicians' acknowledged its potential to complement traditional therapies. However, there are still gaps in understanding VR's therapeutic applications, particularly concerning its impact on human interaction and its suitability for specific patient groups. Balancing VR's clinical benefits with ethical and safety concerns is crucial, especially when working with vulnerable populations. Furthermore, structural and administrative support is essential to overcoming the financial and logistical challenges of VR implementation, ensuring its safe and effective integration into mental health care.

CONCLUSION

While VR holds significant potential for enhancing mental health care, its successful integration into clinical practice necessitates addressing existing gaps in knowledge, training, and structural support. By carefully balancing its clinical benefits with ethical, practical, and safety considerations, VR can be effectively utilised as a valuable tool in mental health treatment, providing innovative solutions while ensuring that patient care remains paramount.

Beyond Pharmacology: A Narrative Review of Alternative Therapies for Anxiety Disorders

BACKGROUND

Anxiety disorders significantly reduce patients' quality of life. Current pharmacological treatments, primarily benzodiazepines and antidepressants, are associated with numerous side effects. Consequently, there is a continual search for alternative methods to traditional therapies that are less burdensome for patients and broaden their therapeutic options. Our objective was to determine the role of selected alternative methods in the treatment of anxiety disorders.

METHODS

In this review, we examined recent evidence on alternative treatments for anxiety disorders, including physical activity, mindfulness, virtual reality (VR) technology, biofeedback, herbal remedies, transcranial magnetic stimulation (TMS), cryotherapy, hyperbaric therapy, vagus nerve stimulation (VNS), 3,4-methylenedioxymethamphetamine (MDMA), electroconvulsive therapy (ECT), and eye movement desensitization and reprocessing (EMDR) therapy. For this purpose we reviewed PubMed and after initial search, we excluded works unrelated to our aim, non-orginal data and animal studies. We conducted second search to cover all minor methods.

RESULTS

We included 116 studies, which data is presented in Tables. We have investigated which methods can support treatment and which can be used as a stand-alone treatment. We assessed the risks to benefits of using alternative treatments.

CONCLUSION

Alternative treatments significantly expand the options available to patients and clinicians, with many serving as adjuncts to traditional therapies. Among the methods presented, mindfulness has the most significant therapeutic potential.

Virtual reality exposure therapy for social anxiety disorders: a meta-analysis and meta-regression of randomized controlled trials

BACKGROUND AND OBJECTIVES

Virtual reality exposure therapy offers a unique opportunity to treat social anxiety disorder. This meta-analysis aims to evaluate the effectiveness of virtual reality exposure therapy compared to waitlist comparators or other interventions for individuals with social anxiety disorder in alleviating anxiety symptoms.

METHODS

A three-step comprehensive search for the randomized controlled trials of virtual reality exposure therapy was conducted from inception to 7 December 2023. The overall effect was measured using Hedges' g and determined using t-statistics at a significance level of p < 0.05. Sensitivity, subgroup, and meta-regression analyses were carried out.

RESULTS

A total of 17 randomized control trials were retrieved from nine electronic databases. Virtual reality exposure therapy has greater efficacy than waitlist comparators in reducing anxiety symptoms at post-intervention and follow-up assessment. Virtual reality exposure therapy demonstrates a similar effect to other interventions at post-intervention and follow-up assessment. We observed a greater effect for participants with symptomatic social anxiety when we combined the intervention with cognitive behavioral therapy compared to its counterpart. Meta-regression analyses found no significant covariate.

CONCLUSIONS

Overall, virtual reality exposure therapy can provide supplementary therapy for improving anxiety symptoms. Additional high-quality and large-scale trials with long-term follow-up are needed.

Virtual Reality and Higher Education Sporting Events: Social Anxiety Perception as an Outcome of VR Simulation

BACKGROUND

This study investigates the relationship between Virtual Reality Exposure Therapy (VRET) and social anxiety in sport environments. Social anxiety is a mental health condition that manifests people's intense fear of being watched and judged by others and worrying about humiliation It is important to research potential tools like VRET that could help to mitigate the impact of social anxiety as people with social anxiety often avoid attending live events due to the venue's sensory stimuli and the social encounters they anticipate. VR simulation could allow socially anxious individuals to fully experience a sporting event simulation minus the anxiety induced by potential social encounters. VR's therapeutic effects on social anxiety should be explored when considering several findings of VR intervention to mental health.

AIM

The study aims to assess the impact of exposing socially anxious people to a virtual sporting game by measuring their levels of social anxiety, team identification, and intentions to attend a live sporting event before and after the VR exposure. Due to VR's positive experience, social anxiety is expected to decrease. However, team identification and intentions to attend live sporting events are expected to increase because of VR's ability to develop sport fanship.

METHOD

Fourteen students with symptoms of social anxiety participated in the study. To create the VR simulation stimuli, the researchers used six 360° cameras to record an NCAA Division-I women's volleyball game. Participants experienced the sporting event via VR simulation. Data were analyzed via one-group pre- and post-comparison.

RESULTS AND CONCLUSIONS

Significant results were found for behavioral intentions of participants after experiencing the simulation. Social anxiety's difference was negative 0.22, t(13) = 3.47, p < 0.01. After watching the game in VR, the respondents' social anxiety decreased significantly. Team identification's difference was 0.53, t(13) = -3.56, p < 0.01. Lastly, event visit intentions' difference was 0.24, t(13) = -2.35, p < 0.05. Team identification and intentions to visit a sporting event rose significantly after viewing the game in VR.

Study on the efficiency of virtual reality in the treatment of alcohol use disorder: study protocol for a randomized controlled trial : E-Reva

CONTEXT

According to the World Health Organization, alcohol is a major global public health problem, leading to a significant increase in illness and death. To treat alcohol use disorders, new therapeutic tools are being promoted, among which virtual reality (VR) shows promise. Previous research has demonstrated the efficacy of VR in reducing alcohol cravings in patients, but there is a lack of data on its effectiveness in maintaining abstinence or reducing consumption in recently abstinent individuals. The E-Reva study aims to compare the efficacy of a treatment strategy combining virtual reality cue exposure therapy (VR-CET) and cognitive behavioral therapy (CBT) with conventional CBT in reducing alcohol consumption and craving in patients with alcohol use disorder (AUD). In addition to this primary objective, the study will compare the effects of VR-CET combined with CBT on anxiety, depression, rumination, and feelings of self-efficacy versus conventional CBT.

METHODS

This prospective randomized controlled trial will be conducted over 8 months in four addiction departments in France. It includes two parallel groups: i) the VR-CET + CBT group, and ii) the CBT-only group, which serves as a control group. Participants will be recruited by the investigating doctor in the addiction centers. The sample will consist of 156 patients diagnosed with AUD and abstinent for at least 15 days. Both treatment groups will participate in four group CBT sessions followed by four individual sessions: i) the VR-CET group will be exposed to virtual environments associated with alcohol-related stimuli, ii) the CBT-only group will receive traditional CBT sessions. After completion of the 8 sessions, patients will be followed up for 6 months. The primary outcome is the cumulative number of standard drinks consumed at 8 months, assessed using the TLFB method.

DISCUSSION

Despite the promise of VR-CET to reduce the desire to drink, the effect on alcohol consumption remains uncertain in the existing literature. Our protocol aims to address the limitations of previous research by increasing sample size, targeting consumption reduction, and incorporating neutral environments. E-Reva aims to enrich the literature on the use of VR in the treatment of AUD and open new perspectives for future interventions.

The efficacy of psychotherapy for social anxiety disorder, a systematic review and meta-analysis

BACKGROUND

Given the growth in research examining the effects of psychotherapy on social anxiety disorder (SAD), an up-to-date comprehensive meta-analysis in this field is needed.

METHODS

We selected studies from a database of randomized trials (RCTs) on psychotherapies for anxiety disorders (last updated search of PubMed, PsycINFO, Embase, and Cochrane (CENTRAL): 1 January 2024) We included RCTs comparing psychotherapy to a control condition for adults with SAD and conducted random effects meta-analyses to examine the efficacy of psychotherapy compared to control conditions at post-treatment.

RESULTS

Sixty-six RCTs were included with 5560 participants and 98 comparisons between psychotherapy and control groups. Psychotherapy was effective in reducing SAD symptoms, with a large effect size (g = 0.88; 95 % CI: 0.76 to 1.0; I2 = 74 %; 95 % CI: 69 to 79, NNT = 3.8). Effects remained robust across sensitivity analyses. However, there was evidence for significant risk of bias in the included trials. The multivariable meta-regression indicated significant differences in treatment delivery formats, type of recruitment strategy, target group, and number of sessions.

CONCLUSION

Psychotherapy is an effective treatment for SAD, with moderate to large effect sizes across all treatment types and formats. Future research is needed to determine the long-term effects.

Virtual Reality Could Help Assess Sexual Aversion Disorder

Virtual reality (VR) may improve our understanding of sexual dysfunctions' manifestations, although research in this area remains limited. This study assessed the potential use of a VR Behavior Avoidance Test (VR-BAT) as a tool for examining the clinical features of Sexual Aversion Disorder (SAD): the experience of fear, disgust, and avoidance when facing sexual cues/contexts. A sample of 55 adults (≥ 18y) with (n = 27) and without SAD (n = 28) completed a self-report measure of sexual avoidance. Their anxiety, disgust, electrodermal activity, heart rate, and visual and behavioral avoidance were then examined during two VR-BATs involving sexual or non-sexual stimuli. Mixed repeated measures ANOVAs, t-tests, and correlational analyses were performed. Results showed that individuals in the SAD group reported greater anxiety and disgust compared to their non-SAD counterparts during the sexual stimuli condition. Sexual avoidance scores were largely positively related to anxiety and disgust during the VR sexual condition, and moderately negatively related to the time spent touching the virtual character's genitals. This study is important given the prevalence of sexual difficulties, such as SAD, and the new research avenues offered by emerging technologies, like VR.

Examining the Efficacy of Extended Reality-Enhanced Behavioral Activation for Adults With Major Depressive Disorder: Randomized Controlled Trial

BACKGROUND

Major depressive disorder (MDD) is a global concern with increasing prevalence. While many evidence-based psychotherapies (EBPs) have been identified to treat MDD, there are numerous barriers to patients accessing them. Virtual reality (VR) has been used as a treatment enhancement for a variety of mental health disorders, but few studies have examined its clinical use in treating MDD. Behavioral activation (BA) is a simple yet effective and established first-line EBP for MDD that has the potential to be easily enhanced and adapted with VR technology. A previous report by our group explored the feasibility and acceptability of VR-enhanced BA in a small clinical proof-of-concept pilot. This study examines the clinical efficacy of a more immersive extended reality (XR)-enhanced BA (XR-BA) prototype. This is the first clinical efficacy test of an XR-BA protocol.

OBJECTIVE

This study examined whether XR-BA was feasible and efficacious in treating MDD in an ambulatory telemedicine clinic.

METHODS

A nonblinded between-subject randomized controlled trial compared XR-BA to traditional BA delivered via telehealth. The study used a previously established, brief 3-week, 4-session BA EBP intervention. The experimental XR-BA participants were directed to use a Meta Quest 2 (Reality Labs) VR headset to engage in simulated pleasant or mastery activities and were compared to a control arm, which used only real-life mastery or pleasant activities as between-session homework. The Patient Health Questionnaire (PHQ)-9 was the primary outcome measure. Independent-sample and paired-sample t tests (2-tailed) were used to determine statistical significance and confirmed using structural equation modeling.

RESULTS

Overall, 26 participants with MDD were randomized to receive either XR-BA (n=13, 50%) or traditional BA (n=13, 50%). The mean age of the 26 participants (n=6, 23% male; n=19, 73% female; n=1, 4% nonbinary or third gender) was 50.3 (SD 17.3) years. No adverse events were reported in either group, and no substantial differences in dropout rates or homework completion were observed. XR-BA was found to be statistically noninferior to traditional BA (t18.6=-0.28; P=.78). Both the XR-BA (t9=2.5; P=.04) and traditional BA (t10=2.3; P=.04) arms showed a statistically significant decrease in PHQ-9 and clinical severity from the beginning of session 1 to the beginning of session 4. There was a significant decrease in PHQ-8 to PHQ-9 scores between the phone intake and the beginning of session 1 for the XR-BA group (t11=2.6; P=.03) but not the traditional BA group (t11=1.4; P=.20).

CONCLUSIONS

This study confirmed previous findings that XR-BA may be a feasible, non-inferior, and acceptable enhancement to traditional BA. Additionally, there was evidence that supports the potential of XR to enhance expectation or placebo effects. Further research is needed to examine the potential of XR to improve access, outcomes, and barriers to MDD care.

Real-Time Classification of Anxiety in Virtual Reality Therapy Using Biosensors and a Convolutional Neural Network

Virtual Reality Exposure Therapy is a method of cognitive behavioural therapy that aids in the treatment of anxiety disorders by making therapy practical and cost-efficient. It also allows for the seamless tailoring of the therapy by using objective, continuous feedback. This feedback can be obtained using biosensors to collect physiological information such as heart rate, electrodermal activity and frontal brain activity. As part of developing our objective feedback framework, we developed a Virtual Reality adaptation of the well-established emotional Stroop Colour-Word Task. We used this adaptation to differentiate three distinct levels of anxiety: no anxiety, mild anxiety and severe anxiety. We tested our environment on twenty-nine participants between the ages of eighteen and sixty-five. After analysing and validating this environment, we used it to create a dataset for further machine-learning classification of the assigned anxiety levels. To apply this information in real-time, all of our information was processed within Virtual Reality. Our Convolutional Neural Network was able to differentiate the anxiety levels with a 75% accuracy using leave-one-out cross-validation. This shows that our system can accurately differentiate between different anxiety levels.

Virtual reality-assisted cognitive behavioral therapy for patients with alcohol use disorder: a randomized feasibility study

Introduction

Cognitive behavioral therapy (CBT) is an evidence-based treatment for alcohol use disorder (AUD). Exposure to high-risk situations in virtual reality (VR) has been suggested to have a potential therapeutical benefit, but no previous study has combined VR and CBT for AUD. We aimed to investigate the feasibility of using VR-simulated high-risk environments in CBT-based treatment of AUD.

Methods

We randomized ten treatment-seeking AUD-diagnosed individuals to three sessions of conventional CBT or VR-assisted CBT performed at two outpatient clinics in Denmark. In each session, patients randomized to VR-CBT were exposed to VR-simulations from a restaurant to induce authentic thoughts, emotions, physiological reactions, and craving for CBT purposes. The primary outcome measure was feasibility: Drop-out rate, psychological reactions, and simulator sickness. Secondary outcomes were assessment of preliminary short-term changes in alcohol consumption and craving from baseline to one-week and one-month follow-up. In addition, the study was conducted for training in operationalization of VR equipment, treatment manuals, and research questionnaires.

Results

The majority of patients completed all study visits (90%). VR induced authentic high-risk related thoughts, emotions, and physiological reactions that were considered relevant for CBT by patients and therapists. Four of five patients randomized to VR-CBT experienced cravings during VR simulations, and most of these patients (3/5) experienced mild simulator sickness during VR exposure. The preliminary data showed that patients receiving VR-CBT had more reduction in alcohol consumption than patients receiving conventional CBT at one week- (median 94% vs. 72%) and one-month follow-up (median 98% vs. 55%). Similar results were found regarding changes in cravings.

Conclusion

We demonstrated VR-CBT to be a feasible intervention for patients with AUD which supports continued investigations in a larger randomized clinical trial evaluating the efficacy of VR-CBT.

Effectiveness and User Experience of Virtual Reality for Social Anxiety Disorder: Systematic Review

BACKGROUND

Social anxiety disorder (SAD) is a debilitating psychiatric disorder that affects occupational and social functioning. Virtual reality (VR) therapies can provide effective treatment for people with SAD. However, with rapid innovations in immersive VR technology, more contemporary research is required to examine the effectiveness and concomitant user experience outcomes (ie, safety, usability, acceptability, and attrition) of emerging VR interventions for SAD.

OBJECTIVE

The aim of this systematic review was to examine the effectiveness and user experience of contemporary VR interventions among people with SAD.

METHODS

The Cochrane Library, Emcare, PsycINFO, PubMed, ScienceDirect, Scopus, and Web of Science databases were searched between January 1, 2012, and April 26, 2022. Deduplicated search results were screened based on title and abstract information. Full-text examination was conducted on 71 articles. Studies of all designs and comparator groups were included if they appraised the effectiveness and user experience outcomes of any immersive VR intervention among people with SAD. A standardized coding sheet was used to extract data on key participant, intervention, comparator, outcome, and study design items.

RESULTS

The findings were tabulated and discussed using a narrative synthesis. A total of 18 studies met the inclusion criteria.

CONCLUSIONS

The findings showed that VR exposure therapy-based interventions can generally provide effective, safe, usable, and acceptable treatments for adults with SAD. The average attrition rate from VR treatment was low (11.36%) despite some reported user experience difficulties, including potential simulator sickness, exposure-based emotional distress, and problems with managing treatment delivered in a synchronous group setting. This review also revealed several research gaps, including a lack of VR treatment studies on children and adolescents with SAD as well as a paucity of standardized assessments of VR user experience interactions. More studies are required to address these issues.

Patient experience of a virtual reality calm room in a psychiatric inpatient care setting in Sweden: a qualitative study with inpatients

OBJECTIVE

Calm rooms have been developed and implemented in psychiatric inpatient care settings to offer patients a dedicated space for relaxation in a convenient and safe environment. Recent technology developments have enabled virtual reality (VR) equivalents of calm rooms that can be feasibly deployed in psychiatric care settings. While research has shown VR environments to be efficacious in inducing relaxation, little is known how these virtual calm rooms are perceived by patients. The aim of this study was to elucidate patient experiences of using a VR calm room in a psychiatric inpatient setting.

DESIGN

Qualitative interview study. Semi-structured interviews were analysed using qualitive inductive content analysis, which focuses on the interpretation of texts for making replicable and valid inferences.

SETTING

Swedish hospital psychiatric inpatient care setting with a wireless, three degrees-of-freedom VR head-mounted display running a calm room application simulating nature environment.

PARTICIPANTS

20 adult patients (12 women) with bipolar disorder (n=18) or unipolar depression (n=2).

RESULTS

Participants experienced the use of the VR calm room as having a positive impact on them, inducing awareness, calmness and well-being. They were thankful to be offered a non-pharmacological alternative for anxiety relief. Participants also expressed that they had some concerns about how they would react emotionally before using the VR device. However, after use, they highlighted that their overall experience was positive. They also expressed that they could see potential for further development of VR technology in psychiatric care.

CONCLUSIONS

VR technology has the potential to solve pressing logistic issues in offering calm rooms in psychiatric inpatient care. VR calm rooms appear to be appreciated by psychiatric inpatients, who value their accessibility, convenience and variety of modalities offered. Participants perceived an increase in their well-being after use.

Virtual reality efficiency as exposure therapy for alcohol use: A systematic literature review

Virtual reality is an immersive technology that can be used as a tool in the treatment of disorders linked to substance use disorders, such as alcohol use disorder. This systematic review of the literature examines the effectiveness of virtual reality as exposure therapy for heavy social drinkers, defined as people who regularly consume alcohol in a variety of social contexts, with or without a diagnosis of alcohol use disorder. The current review includes ten studies with a total of 377 participants. Most participants were adult men (61.03%), with an age average of 44.1 years [± 7.42] and alcohol use ranging from light to heavy. Although studies show heterogeneous results, the use of virtual reality cue exposure therapies has shown greater improvement in terms of craving reduction for patients suffering from alcohol use disorder. Studies have also shown that the realism of the virtual environment can influence levels of craving and anxiety, both in heavy social drinkers. In addition, the use of virtual reality has proven to increase feeling of self-efficacy and decrease the tendency to engage in automatic drinking behaviors. However, the review also mentions the necessity of larger research to determine the efficiency of virtual reality as a therapeutic treatment for alcohol use disorder, whilst considering comorbidities and treatment background, especially for resistant patients.

Impact of virtual reality applications in the treatment of anxiety disorders: A systematic review and meta-analysis of randomized-controlled trials

BACKGROUND AND OBJECTIVES

Anxiety disorders are the most prevalent mental disorders worldwide. Virtual reality (VR) treatment approaches have increasingly been studied. Before clinical implementation, it is necessary to evaluate the treatment effect of VR applications. The objective is to evaluate the treatment effect of virtual reality applications in the treatment of anxiety disorders compared to conventional therapy.

METHODS

A systematic literature review with meta-analysis was conducted. Four databases were used to identify randomized controlled trials published between April 2011 and April 2021 which compare VR applications with non-VR interventions or waiting lists. Study characteristics, pre- and post-treatment data were extracted. Hedges g was calculated as effect size. Primary outcome was anxiety symptoms.

RESULTS

Data from 17 studies from 827 participants was extracted. The studies examined specific phobia (n = 9), social anxiety disorder (n = 4), agoraphobia (n = 2) and panic disorder (n = 2). 16 out of 17 studies used head-mounted displays as VR application. A non-significant effect size with significant heterogeneity was observed in favor of the use of VR applications in anxiety symptoms (g, 0.33; 95%-CI, -0.20-0.87). Compared to passive control groups, VR applications are associated significant with lower anxiety symptoms (g, 1.29; 95%-CI, 0.68-1.90).

LIMITATIONS

The study and patient characteristics varied between the individual studies which is reflected in a high statistical heterogeneity of the effect sizes.

CONCLUSIONS

The added value of VR applications over waiting-list or psychoeducation only control groups is obvious. VR applications can be used as part of the treatment of anxiety disorders, especially when conventional therapy is unavailable.

Virtual reality interventions for the treatment of anxiety disorders: A scoping review

BACKGROUND

& Objectives: Virtual Reality (VR) refers to an artificial, immersive three-dimensional environment with interactive sensory stimuli. VR is typically incorporated into the psychotherapeutic process as a means of providing exposure therapy. The objectives of this scoping review were to synthesize the most up-to-date evidence on the outcomes, acceptability, and side effects of VR interventions for treating anxiety disorders in adults.

METHODS

This scoping review is grounded in the methodological framework of Arksey and O'Malley (2005). The databases searched were PubMed, EMBASE, Web of Science, PsycINFO, and ProQuest Dissertations and Theses.

RESULTS

The search process identified 112 unique citations. 52 (46%) of the eligible articles examined participants with specific phobias, 25 (22%) with PTSD, 21 (19%) with social anxiety disorder, 12 (10%) with panic disorder with or without agoraphobia, and 3 (3%) with generalized anxiety disorder. VR interventions often led to statistically significant and meaningful reductions in symptoms for people with anxiety disorders. Additionally, they were acceptable to clients and associated with minimal side effects for all types of anxiety disorders, except for Combat-Related PTSD in Vietnam veterans.

LIMITATIONS

Limitations included the fact that the studies in this review were of varying quality, and that articles in languages other than English and French were excluded.

CONCLUSION

VR interventions appeared to be a viable alternative to conventional exposure therapy. Future research should include more male participants and have a stronger emphasis on acceptability and side effects. Increased traction for VR interventions for generalized anxiety disorder and panic disorder is also important.

A Literature Review Examining Virtual Reality Exposure Therapy for Individuals Diagnosed With Social Anxiety Disorder

ABSTRACT

Social anxiety disorder (SAD) is a specific subtype of anxiety disorder where individuals experience uncomfortable social situations that induce anxious feelings including nervousness and panic. Computer technology has been applied in interventions for many mental health disorders. We aim to understand and explore the use of virtual reality exposure therapy (VRET) to treat adults with SAD. We conducted a literature search using relevant mesh keywords in PubMed and PsycINFO. Six studies met inclusion criteria in our final qualitative synthesis review. Results showed a significant reduction in SAD symptom severity based on primary measures in all studies, suggesting that VRET is an effective option in treating SAD. Studies have shown the success of VRET in formats such as a single-user implementation, one-session treatment, and self-training intervention. In conclusion, VRET is effective in reducing SAD symptoms. The limitations of most studies included a small sample size and weak ecological validity. Future research can examine VRET with a more extensive clinical sample and broader social behaviors.

Validation of a Virtual Environment to Induce State Social Physique Anxiety in Women with Obesity and Social Physique Anxiety

State Social Physique Anxiety (SPA), in contrast to Trait SPA, is triggered by specific situations that elicit SPA. To date, no research has used virtual reality (VR) to recreate a situation that may elicit State SPA. The purpose of this study is to validate a virtual environment (VE) that simulates an anxiogenic situation to induce State SPA in women with obesity and high SPA. The high SPA group consisted of 25 self-identified women living with obesity and high Trait SPA. The low SPA group consisted of 20 self-identified women with low SPA. All participants were immersed in a virtual swimming pool environment for 10 min using a virtual reality headset. After the immersion, State SPA and fear of being negatively judged felt during immersion were measured with self-report questionnaires. A questionnaire assessing unwanted negative side effects was administered before and after the immersion. Using an ANCOVA with Trait SPA as covariate, State SPA was found to be significantly higher in the high SPA group. Fear of being judged negatively was also significantly higher in the high SPA group. Unwanted negative side effects scores did not increase post-immersion in either group. This study documents the validity of a novel VE for inducing State SPA in women with obesity and high SPA.

Internet-Based Cognitive Behavioral Therapy and Virtual Reality Exposure Therapy for Social Anxiety Disorder: Protocol for a Randomized Controlled Trial in Hong Kong

BACKGROUND

Social anxiety disorder (SAD), also known as social phobia, is one of the most common mental disorders worldwide. In Hong Kong, the prevalence of SAD is high, but its treatment rate is low. SAD has immense impact on academic or work performance, social life, career development, and quality of life. One of the most effective treatments for SAD is cognitive behavioral therapy (CBT), with internet-based CBT (iCBT) and virtual reality exposure therapy (VRET) showing promise in treating SAD. However, internet interventions are underdeveloped in Chinese communities including Hong Kong.

OBJECTIVE

This study aims to develop an iCBT program that includes VRET, called "Ease Anxiety in Social Event Online" (Ease Online), for Hong Kong adults with SAD in a randomized controlled trial.

METHODS

The 14-week Ease Online program is a guided self-help iCBT program with a blended mode of service delivery. The program comprises 9 web-based modules and 5 individual counseling sessions (including 2 VRET sessions) conducted remotely or face-to-face with a therapist to provide therapist support, as guided iCBT shows superior effects than unguided iCBT. Other program components include therapist feedback on assignments, internal messages, forums, client portfolios, web-based questionnaires, reminders, and web-based bookings. The program can be accessed either through a mobile app or program website through a PC with an internet connection. The participants are openly recruited and screened using a questionnaire and through an intake interview. Eligible participants are randomized by placing them into a web-based iCBT group, app-based iCBT group, or a waitlist control (WLC) group. Participants in the WLC group are assigned to the app-based program upon completion of the service of the 2 experimental groups. Measurements of social anxiety, depression and anxiety symptoms, psychological distress, automatic thoughts, and quality of life are administered at pretest, posttest, and 3- and 6-month follow-ups. Multivariate ANOVA with repeated measures will be performed to determine the intervention effectiveness on the continuous variables over time.

RESULTS

Participant recruitment commenced in January 2021. As of February 2023, a total of 1811 individuals applied for the Ease Online program. In total, 401 intake interviews have been completed, and 329 eligible participants have joined the program, among whom 166 have completed the service. Data collection is still ongoing, which is expected to be completed in March 2024.

CONCLUSIONS

This study is the first of its kind in combining iCBT and VRET for the treatment of SAD in Hong Kong. At a theoretical level, this study contributes to the development and evaluation of internet-based psychological interventions in Hong Kong. At a practical level, the Ease Online program may serve as an alternative service option for SAD clients in Hong Kong if proven effective.

Virtual Reality Therapy in France: A Therapeutic Innovation Between Technology and Care

The latest form of cognitive behavioral therapy, virtual reality therapy has been developing in France since 2012, in both university hospitals and private practices. Patients receiving this therapy are immersed in a digitally created environment, using a virtual reality headset, in order to be exposed to their phobias. How does the introduction of technical objects such as the virtual reality headset affect and transform the care relationship between the patient and the therapist? Based on an ethnographic study conducted between 2012 and 2018 in the psychiatric unit of a French university hospital, this article outlines the emergence of virtual reality therapy, describes how it operates, and analyzes how it shapes the patient-therapist relationship. I argue that this device-namely virtual reality therapy-promotes a new therapeutic style in psychiatry, whose format and therapeutic indications align with the requirements of evidence-based medicine.

Baseline Severity as a Moderator of the Waiting List-Controlled Association of Cognitive Behavioral Therapy With Symptom Change in Social Anxiety Disorder: A Systematic Review and Individual Patient Data Meta-analysis

Importance

Social anxiety disorder (SAD) can be adequately treated with cognitive behavioral therapy (CBT). However, there is a large gap in knowledge on factors associated with prognosis, and it is unclear whether symptom severity predicts response to CBT for SAD.

Objective

To examine baseline SAD symptom severity as a moderator of the association between CBT and symptom change in patients with SAD.

Data Sources

For this systematic review and individual patient data meta-analysis (IPDMA), PubMed, PsycInfo, Embase, and the Cochrane Library were searched from January 1, 1990, to January 13, 2023. Primary search topics were social anxiety disorder, cognitive behavior therapy, and randomized controlled trial.

Study Selection

Inclusion criteria were randomized clinical trials comparing CBT with being on a waiting list and using the Liebowitz Social Anxiety Scale (LSAS) in adults with a primary clinical diagnosis of SAD.

Data Extraction and Synthesis

Authors of included studies were approached to provide individual-level data. Data were extracted by pairs of authors following the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline, and risk of bias was assessed using the Cochrane tool. An IPDMA was conducted using a 2-stage approach for the association of CBT with change in LSAS scores from baseline to posttreatment and for the interaction effect of baseline LSAS score by condition using random-effects models.

Main Outcomes and Measures

The main outcome was the baseline to posttreatment change in symptom severity measured by the LSAS.

Results

A total of 12 studies including 1246 patients with SAD (mean [SD] age, 35.3 [10.9] years; 738 [59.2%] female) were included in the meta-analysis. A waiting list-controlled association between CBT and pretreatment to posttreatment LSAS change was found (b = -20.3; 95% CI, -24.9 to -15.6; P < .001; Cohen d = -0.95; 95% CI, -1.16 to -0.73). Baseline LSAS scores moderated the differences between CBT and waiting list with respect to pretreatment to posttreatment symptom reductions (b = -0.22; 95% CI, -0.39 to -0.06; P = .009), indicating that individuals with severe symptoms had larger waiting list-controlled symptom reductions after CBT (Cohen d = -1.13 [95% CI, -1.39 to -0.88] for patients with very severe SAD; Cohen d = -0.54 [95% CI, -0.80 to -0.29] for patients with mild SAD).

Conclusions and Relevance

In this systematic review and IPDMA, higher baseline SAD symptom severity was associated with greater (absolute but not relative) symptom reductions after CBT in patients with SAD. The findings contribute to personalized care by suggesting that clinicians can confidently offer CBT to individuals with severe SAD symptoms.

Engaging in Awkward Social Interactions in a Virtual Environment Designed for Exposure-Based Psychotherapy for People with Generalized Social Anxiety Disorder: An International Multisite Study

The effectiveness of in virtuo exposure-based treatment of performance-only social anxiety disorder (SAD) has been demonstrated in several studies. However, few studies have validated virtual environments with participants suffering from generalized SAD. The goal of this study is to confirm the potential of a virtual environment in inducing anxiety in adults suffering from generalized SAD, compared to adults without SAD, when engaged in awkward social interactions. Differences between participants from two different countries were also explored. The sample consisted of 15 participants with SAD from Canada, 17 participants without SAD from Canada, 16 participants with SAD from Spain, and 21 participants without SAD from Spain. All participants were immersed in a control virtual environment and in an experimental virtual environment considered potentially anxiety-inducing for individuals with generalized SAD. As hypothesized, results showed that the experimental virtual environment induced a higher level of anxiety than the control environment among participants with SAD compared to those without SAD. The impact on anxiety of each socially threatening task performed during the experimental immersion was statistically significant. In terms of anxiety responses, no significant differences were found between participants from Canada and Spain. However, spatial presence and ecological validity were higher in Canadians than in Spaniards. Unwanted negative side effects induced by immersions in virtual reality were higher in the SAD group. This study highlights the importance for therapists to engage people with SAD in clinically relevant tasks while immersed in VR psychotherapeutic applications.

Modification of the therapist's facial expressions using virtual reality technology during the treatment of social anxiety disorder: a case series

Exposure therapy is a mainstream of treatment for social anxiety disorder (SAD). However, effort and time are required to recreate interpersonal situations that produce moderate anxiety. On the other hand, virtual reality exposure therapy can easily control anxiety-inducing conditions and allow for graduated exposure. However, artificial intelligence and animations that speak as naturally as actual humans are not yet practical, adding to the limitations of these treatments. The authors propose the use of a virtual reality technology that can transform facial expressions into smiling or sad faces in real time and display them on a monitor, potentially solving the above-mentioned problems associated with virtual reality animations. This feasibility study was conducted to determine whether this system can be safely applied to the treatment of SAD patients. A total of four SAD patients received 16 exposure therapy sessions led by an experienced therapist over a monitor; throughout the sessions, the facial expressions of the therapist were modified using software to display expressions ranging from smiling to sad on the monitor that was being viewed by the patient. Client satisfaction, treatment alliance, and symptom assessments were then conducted. Although one patient dropped out of the study, treatment satisfaction and treatment alliance were scored high in all the cases. In two of the four cases, the improvement in symptoms was sustained over time. Exposure therapy in which the interviewer's facial expressions are modified to induce appropriate levels of anxiety in the patient can be safely used for the treatment of SAD patients and may be effective for some patients.

Virtual Reality Exposure Therapy as a Treatment Method Against Anxiety Disorders and Depression-A Structured Literature Review

Mental illness is a growing global health problem affecting individuals and society. In Sweden, the number of people suffering from mental health illnesses, such as anxiety and depression, is increasing and is expected to be one of the largest public health challenges in 2030. As mental illness increases, the area also needs effective forms of treatment. This study aims to investigate if Virtual Reality Exposure Therapy (VRET) works as a treatment method for adults suffering from anxiety disorders and depression. A structured literature review based on 24 articles found in the databases PubMed, MEDLINE, CINAHL and PsycInfo. Two reviewers independently reviewed and collectively extracted data from the included articles. The articles have been analyzed by using thematic analysis. The results suggest that Virtual reality exposure therapy can work as an effective treatment method for adults with anxiety disorders. It also indicates that VRET may act as a health-promoting intervention to reduce anxiety disorders, phobias, and depression symptoms. Virtual reality exposure therapy can be an effective treatment method and health-promoting effort against anxiety disorders in adults. An essential factor for the patients who accept VRET as a treatment is the initial information therapists give.

Systematic review and meta-analysis of randomised controlled trials for evaluating the effectiveness of virtual reality therapy for social anxiety disorder

OBJECTIVE

To evaluate the effectiveness of VR therapy (VRT) for symptoms related to social anxiety disorder (SAD), namely fear and avoidance of social interactions and performance situations (FASIP), fear of negative evaluation (FNE), anxiety and depression, a systematic review and meta-analysis were performed.

METHODS

Medline, PubMed, Science Direct, Web of Science, CINAHL, PsychINFO and Scopus were searched to include randomised controlled trials of VRT for SAD that met the criteria. A total of 15 RCTs with 720 participants published between 1998 and 2022 were included. Hedge's g with a 95 % confidence interval (CI) was adopted to compute the effect sizes.

RESULTS

Results showed no difference between the effect of VRT and CBT on FASIP, FNE, anxiety and depression and a large effect size for VRT versus the waitlist control group on FASIP (g = -1.170, 95 % CI: -2.056-0.283; p < 0.010). The moderator analysis demonstrated that VRT was superior to the controlled group in addressing FASIP, FNE and anxiety when the sample size was smaller than 50 and the number of sessions was five or fewer.

LIMITATIONS

Differences in hardware, software and intervention duration for VRT across studies.

CONCLUSION

This study confirmed the feasibility of VRT in alleviating the FASIP in patients with SAD, with the waitlist control group as a comparison. However, the effectiveness of VRT was not significant in FASIP, FNE, anxiety and depression compared to cognitive behavioural therapy (CBT). Additional social interaction scenarios should be developed in VRT, standardised hardware should be used and the proper length of exposure time to VR should be determined to enhance the efficacy of VRT.

Virtual reality-assisted cognitive behavioural therapy for outpatients with alcohol use disorder (CRAVR): a protocol for a randomised controlled trial

INTRODUCTION

Alcohol use disorder (AUD) is a brain disorder linked to over 200 health conditions. Cognitive behavioural therapy (CBT) is considered the best practice in the treatment of AUD, but more than 60% of patients relapse within the first year after treatment. Psychotherapy combined with virtual reality (VR) has received increasing interest in the treatment of AUD. However, existing studies have primarily investigated the use of VR for cue reactivity. We therefore aimed to investigate the effect of VR-assisted CBT (VR-CBT).

METHODS AND ANALYSIS

This study is an assessor-blinded, randomised clinical trial being conducted at three outpatient clinics in Denmark. We will randomise 102 patients to 14 individual sessions of either manualised VR-CBT or CBT. The VR-CBT group will receive exposure to immersive high-risk VR situations from a pub, bar/party, restaurant, supermarket and at-home (30 videos) to activate high-risk-related beliefs and cravings for subsequent modification using CBT techniques. The treatment period is 6 months, and follow-up visits will be performed 3, 6, 9 and 12 months after inclusion. The primary outcome measure is the change in total alcohol consumption from baseline to 6 months after inclusion, measured with the Timeline Followback Method. Key secondary outcome measures include changes in the number of heavy drinking days, alcohol cravings, cognition, and symptoms of depression and anxiety.

ETHICS AND DISSEMINATION

Approval has been obtained by the research ethics committee in the Capital Region of Denmark (H-20082136) and the Danish Data Protection Agency (P-2021-217). All patients will receive both oral and written information about the trial and written informed consent will be obtained from each patient before inclusion. The study results will be disseminated in peer-reviewed publications and conference presentations.

Speech-Language Pathologists' Views of Using Virtual Reality for Managing Cognitive-Communication Disorders Following Traumatic Brain Injury

PURPOSE

Using virtual reality (VR) to support rehabilitation is an emerging area of research that may offer people with communication disorders a stable and safe communication environment to practice their communication skills. There are currently no VR applications that have been designed to assess or treat cognitive-communication disorders (CCDs) following traumatic brain injury (TBI). Therefore, this study aimed to explore the views of speech-language pathologists (SLPs) who work with people who have a TBI to generate ideas and considerations for using VR in rehabilitation for CCDs. VR researchers were included to provide expert advice about VR technology.

METHOD

A total of 14 SLPs and three VR specialists participated in an online interview or focus group. Semistructured discussions explored participants' perspectives related to potential ideas for VR use and any perceived barriers and facilitators to VR implementation for managing CCDs following TBI. Data were video- and audio-recorded, transcribed, and analyzed qualitatively using thematic analysis.

RESULTS

Three main themes were generated from thematic analysis: VR is a tool that could enhance clinical practice, the need to consider and navigate potential red flags, and solutions to pave the way forward. Suggestions to overcome perceived barriers to VR use were also provided.

DISCUSSION

Participants expressed interest in using VR for rehabilitation of CCDs following TBI. However, potential barriers and risks to use should be considered prior to implementation. The findings offer guidance to support future research and development of VR in this field.

Review of Psychophysiological and Psychotherapeutic Studies of Stress Using Virtual Reality Technologies

This review addresses the use of virtual reality technologies in the psychophysiology and psychotherapy of stress. Studies using virtual reality both to introduce subjects into a state of stress and to help reduce stress reactions are reviewed. Methods developed for treating patients suffering from stress-related disorders (in particular, PTSD and phobias) are described. In many cases, reductions in stress reactions with the help of virtual reality systems are achieved not only at the self-report (experiential) level, but also at the level of central and peripheral nervous system measures. This allows virtual reality to be regarded as a modern, inexpensive, and effective method, firstly, for introducing subjects into a state of stress with the aim of testing various hypotheses in psychophysiology and, secondly, to reduce stress reactions.

The reality of virtual reality

Virtual reality (VR) has become a popular tool for investigating human behavior and brain functions. Nevertheless, it is unclear whether VR constitutes an actual form of reality or is more like an advanced simulation. Determining the nature of VR has been mostly achieved by self-reported presence measurements, defined as the feeling of being submerged in the experience. However, subjective measurements might be prone to bias and, most importantly, do not allow for a comparison with real-life experiences. Here, we show that real-life and VR height exposures using 3D-360° videos are mostly indistinguishable on a psychophysiological level (EEG and HRV), while both differ from a conventional 2D laboratory setting. Using a fire truck, three groups of participants experienced a real-life (N = 25), a virtual (N = 24), or a 2D laboratory (N = 25) height exposure. Behavioral and psychophysiological results suggest that identical exogenous and endogenous cognitive as well as emotional mechanisms are deployed to process the real-life and virtual experience. Specifically, alpha- and theta-band oscillations in line with heart rate variability, indexing vigilance, and anxiety were barely indistinguishable between those two conditions, while they differed significantly from the laboratory setup. Sensory processing, as reflected by beta-band oscillations, exhibits a different pattern for all conditions, indicating further room for improving VR on a haptic level. In conclusion, the study shows that contemporary photorealistic VR setups are technologically capable of mimicking reality, thus paving the way for the investigation of real-world cognitive and emotional processes under controlled laboratory conditions.

Virtual reality exposure therapy for reducing social anxiety in stuttering: A randomized controlled pilot trial

We report on findings from the first randomized controlled pilot trial of virtual reality exposure therapy (VRET) developed specifically for reducing social anxiety associated with stuttering. People who stutter with heightened social anxiety were recruited from online adverts and randomly allocated to receive VRET (n = 13) or be put on a waitlist (n = 12). Treatment was delivered remotely using a smartphone-based VR headset. It consisted of three weekly sessions, each comprising both performative and interactive exposure exercises, and was guided by a virtual therapist. Multilevel model analyses failed to demonstrate the effectiveness of VRET at reducing social anxiety between pre- and post-treatment. We found similar results for fear of negative evaluation, negative thoughts associated with stuttering, and stuttering characteristics. However, VRET was associated with reduced social anxiety between post-treatment and one-month follow-up. These pilot findings suggest that our current VRET protocol may not be effective at reducing social anxiety amongst people who stutter, though might be capable of supporting longer-term change. Future VRET protocols targeting stuttering-related social anxiety should be explored with larger samples. The results from this pilot trial provide a solid basis for further design improvements and for future research to explore appropriate techniques for widening access to social anxiety treatments in stuttering.

The gold-standard treatment for social anxiety disorder: A roadmap for the future

Exposure therapy (ET), which follows the Pavlovian extinction model, is regarded as the gold-standard treatment for social anxiety disorder (SAD). The prospect of virtual reality in lieu of a traditional laboratory setting for the treatment of SAD has not been rigorously explored. The aim of the review was to summarize, find gaps in the current literature, and formulate future research direction by identifying two broad research questions: the comparative efficacy between in vivo ET and virtual reality exposure therapy (VRET) and the effectiveness of the Pavlovian extinction model in treating SAD. The criteria for effectiveness were effect size, relapse prevention, attrition rate and ecological validity. A literature search on recent randomized controlled trials yielded a total of 6 original studies (N=358), excluding duplication and overlapping participants. All studies supported that VRET was as effective as in vivo ET. Behavioral therapy that follows classical conditioning principles has a high attrition and relapse rate. Comparisons were drawn between the efficacy of the Pavlovian extinction model and other existing models, including third-wave approaches. The neural markers are suggested to be included as efficacy measures in treating SAD. The gold-standard treatment for SAD requires a paradigm shift through rigorous longitudinal comparative studies.

Describing epilepsy-related anxiety to inform the design of a virtual reality exposure therapy: Results from Phase 1 of the AnxEpiVR clinical trial

People with epilepsy (PwE) are at a greater risk of comorbid anxiety, which is often related to the fear of having another seizure for safety or social reasons. While virtual reality (VR) exposure therapy (ET) has been successfully used to treat several anxiety disorders, no studies to date have investigated its use in this population. This paper discusses Phase 1 of the three-phase AnxEpiVR pilot study. In Phase 1, we aimed to explore and validate scenarios that provoke epilepsy/seizure-specific (ES) interictal anxiety and provide recommendations that lay the foundation for designing VR-ET scenarios to treat this condition in PwE. An anonymous online questionnaire (including open- and closed-ended questions) that targeted PwE and those affected by it (e.g., through a family member, friend, or as a healthcare professional) was promoted by a major epilepsy foundation in Toronto, Canada. Responses from n = 18 participants were analyzed using grounded theory and the constant comparison method. Participants described anxiety-provoking scenes, which were categorized under the following themes: location, social setting, situational, activity, physiological, and previous seizure. While scenes tied to previous seizures were typically highly personalized and idiosyncratic, public settings and social situations were commonly reported fears. Factors consistently found to increase ES-interictal anxiety included the potential for danger (physical injury or inability to get help), social factors (increased number of unfamiliar people, social pressures), and specific triggers (stress, sensory, physiological, and medication-related). We make recommendations for incorporating different combinations of anxiety-related factors to achieve a customizable selection of graded exposure scenarios suitable for VR-ET. Subsequent phases of this study will include creating a set of VR-ET hierarchies (Phase 2) and rigorously evaluating their feasibility and effectiveness (Phase 3).

Virtual Reality Interventions for Mental Health

Virtual Reality (VR) is a growing field in psychological research and therapy. While there is strong evidence for the efficacy of exposure therapy in VR (VRET) to treat anxiety disorders, new opportunities for using VR to treat mental health disorders are emerging. In this chapter, we first describe the value of VRET for the treatment of several anxiety disorders. Next, we introduce some recent developments in research using VR investigating schizophrenia, neurodevelopmental disorders, and eating disorders. This includes therapeutic strategies beyond VRET, including avatar-based therapies or those combining VR with biofeedback approaches. Although VR offers many convincing advantages, contraindications in treatment must be considered when implementing VR-supported therapy in clinical practice. Finally, we provide an outlook for future research, highlighting the integration of augmented reality and automation processes in VR environments to create more efficient and tailored therapeutic tools. Further, future treatments will benefit from the gamification approach, which integrates elements of computer games and narratives that promote patients' motivation and enables methods to reduce drop-outs during psychological therapy.

Virtual reality for healthcare: A scoping review of commercially available applications for head-mounted displays

Objective

This scoping review aimed to describe the scope of commercially available virtual reality (VR) healthcare applications for mainstream head-mounted displays (HMD)s.

Methods

A search was conducted during late April and early May 2022 over five major VR app stores using "health," "healthcare," "medicine," and "medical" as keywords. Apps were screened based on their title and description sections. Metadata collected included: title, description, release date, price (free or paid), multilingual support, VR app store availability, and HMD support.

Results

The search yielded 1995 apps, out of which 60 met the inclusion criteria. The analysis showed that the number of healthcare VR apps has been steadily increasing since 2016, but no developer has released more than two apps so far. Most of the reviewed apps can run on HTC Vive, Oculus Quest, and Valve Index. Thirty-four (56.7%) apps had a free version, and 12 (20%) apps were multilingual, i.e., supported languages other than English. The reviewed apps fell into eight major themes: life science education (3D anatomy, physiology and pathology, biochemistry, and genetics); rehabilitation (physical, mental, and phobia therapy); public health training (safety, life-saving skills, and management); medical training (surgical and patient simulators); role-playing as a patient; 3D medical imagery viewing; children's health; and online health communities.

Conclusions

Although commercial healthcare VR is still in its early phases, end-users can already access a broad range of healthcare VR apps on mainstream HMDs. Further research is needed to assess the usefulness and usability of existing apps.

Virtual reality in the diagnostic and therapy for mental disorders: A systematic review

BACKGROUND

Virtual reality (VR) technologies are playing an increasingly important role in the diagnostics and treatment of mental disorders.

OBJECTIVE

To systematically review the current evidence regarding the use of VR in the diagnostics and treatment of mental disorders.

DATA SOURCE

Systematic literature searches via PubMed (last literature update: 9^th of May 2022) were conducted for the following areas of psychopathology: Specific phobias, panic disorder and agoraphobia, social anxiety disorder, generalized anxiety disorder, posttraumatic stress disorder (PTSD), obsessive-compulsive disorder, eating disorders, dementia disorders, attention-deficit/hyperactivity disorder, depression, autism spectrum disorder, schizophrenia spectrum disorders, and addiction disorders.

ELIGIBILITY CRITERIA

To be eligible, studies had to be published in English, to be peer-reviewed, to report original research data, to be VR-related, and to deal with one of the above-mentioned areas of psychopathology.

STUDY EVALUATION

For each study included, various study characteristics (including interventions and conditions, comparators, major outcomes and study designs) were retrieved and a risk of bias score was calculated based on predefined study quality criteria.

RESULTS

Across all areas of psychopathology, k = 9315 studies were inspected, of which k = 721 studies met the eligibility criteria. From these studies, 43.97% were considered assessment-related, 55.48% therapy-related, and 0.55% were mixed. The highest research activity was found for VR exposure therapy in anxiety disorders, PTSD and addiction disorders, where the most convincing evidence was found, as well as for cognitive trainings in dementia and social skill trainings in autism spectrum disorder.

CONCLUSION

While VR exposure therapy will likely find its way successively into regular patient care, there are also many other promising approaches, but most are not yet mature enough for clinical application.

Technology and Mental Health: State of the Art for Assessment and Treatment

Technology is ubiquitous in society and is now being extensively used in mental health applications. Both assessment and treatment strategies are being developed and deployed at a rapid pace. The authors review the current domains of technology utilization, describe standards for quality evaluation, and forecast future developments. This review examines technology-based assessments of cognition, emotion, functional capacity and everyday functioning, virtual reality approaches to assessment and treatment, ecological momentary assessment, passive measurement strategies including geolocation, movement, and physiological parameters, and technology-based cognitive and functional skills training. There are many technology-based approaches that are evidence based and are supported through the results of systematic reviews and meta-analyses. Other strategies are less well supported by high-quality evidence at present, but there are evaluation standards that are well articulated at this time. There are some clear challenges in selection of applications for specific conditions, but in several areas, including cognitive training, randomized clinical trials are available to support these interventions. Some of these technology-based interventions have been approved by the U.S. Food and Drug administration, which has clear standards for which types of applications, and which claims about them, need to be reviewed by the agency and which are exempt.

The Effects of Virtual Reality in Targeting Transdiagnostic Factors for Mental Health: A Systematic Review of the Literature

Virtual reality (VR) was found to be effective in the treatment of several specific psychopathologies. However, the effects of VR-based interventions beyond the disorder-specific approach and their ability to improve transdiagnostic factors of mental disorders are unknown. This PRISMA systematic review was conducted using databases PubMed and PsycINFO, searching articles published between 2010 and September 2022. Keywords “emotion regulation”, “cognitive reappraisal”, “avoidance”, “impulsivity”, “aggression”, and “disinhibition” were combined with “virtual reality” to retrieve studies showing the effects of VR-based interventions on these transdiagnostic factors. 29 experimental studies and seven case-studies were selected. A total of 23 considered avoidance, eight dealt with emotion regulation, three concerned aggression, two addressed impulsivity, two dealt with cognitive reappraisal, and none examined disinhibition. Most of the studies included anxiety disorder patients (n = 15), especially with specific phobias (n = 8) and social anxiety disorder (n = 4). VR managed to improve all transdiagnostic factors, with results often maintained at follow-ups (n = 21 studies; range: 1–12 months) and similar to traditional interventions (e.g., cognitive-behavioral therapy). Exploring the transdiagnostic potential of VR may help to reduce costs and improve applicability in clinical psychology. While results were promising, further studies are needed for aggression, impulsivity and cognitive reappraisal, especially including follow-ups, comparisons with first-line treatments, and understudied clinical populations.

Standard CBT versus integrative and multimodal CBT assisted by virtual-reality for generalized anxiety disorder

Introduction

Generalized Anxiety Disorder (GAD) is a prevalent emotional disorder associated with increased dysfunctionality, which has a lasting impact on the individual’s quality of life. Besides medication, Cognitive-Behavioral Therapy (CBT) represents the golden standard psychotherapeutic approach for GAD, integrating multilevel techniques and various delivery formats that enable the development of tailored treatment protocols. The objective of this study was to compare the efficiency of a standard CBT protocol targeting worries, dysfunctional beliefs, and intolerance of uncertainty with an integrative and multimodal CBT intervention augmented with Virtual Reality (VR).

Materials and methods

This study included 66 participants (M_age = 22.53 years; SD = 2.21) with moderate GAD symptoms that were randomized to the standard CBT group (CBTs; N = 32) and the Integrative and Multimodal CBT augmented with VR (IM-VRCBT; N = 34) group. The interventions comprised 10 weekly sessions conducted by trained CBT therapists, including cognitive restructuring, problem-solving, behavioral exposure, and relaxation techniques. Baseline and post-assessments were conducted with both groups. Primary outcome measures included the Hamilton Anxiety Rating Scale (HARS) and Penn-State Worry Questionnaire (PSWQ) to evaluate the severity of GAD symptoms and worries, respectively. Secondary outcomes involved the administration of Automatic Thoughts Questionnaire (ATQ), Dysfunctional Attitudes Scale (DAS) and Unconditional Self-Acceptance Questionnaire (USAQ).

Results

Both interventions determined statistically significant effects on both primary and secondary outcomes (ps < 0.001) in the expected direction. However, CBTs was associated with higher effect sizes for anxiety (Cohen’s d = 2.76) and worries (Cohen’s d = 1.85), in contrast to IM-VRCBT. Also, secondary analyses revealed positive correlations between changes in anxiety and worries level and the reduction of dysfunctional cognitive processes.

Conclusion

This research emphasized the effectiveness of CBT interventions for treating adults with moderate GAD symptomatology. Specifically, both interventions were efficient for reducing anxiety symptomatology present at individuals with GAD. However, regarding cognitive dysfunctions like worries, the standard CBT protocol performed better, as compared to the IM-VRCBT. In addition, we conclude that VR could be integrated within CBT interventions in a single protocol for GAD treatment.

Prediction of Specific Anxiety Symptoms and Virtual Reality Sickness Using In Situ Autonomic Physiological Signals During Virtual Reality Treatment in Patients With Social Anxiety Disorder: Mixed Methods Study

BACKGROUND

Social anxiety disorder (SAD) is the fear of social situations where a person anticipates being evaluated negatively. Changes in autonomic response patterns are related to the expression of anxiety symptoms. Virtual reality (VR) sickness can inhibit VR experiences.

OBJECTIVE

This study aimed to predict the severity of specific anxiety symptoms and VR sickness in patients with SAD, using machine learning based on in situ autonomic physiological signals (heart rate and galvanic skin response) during VR treatment sessions.

METHODS

This study included 32 participants with SAD taking part in 6 VR sessions. During each VR session, the heart rate and galvanic skin response of all participants were measured in real time. We assessed specific anxiety symptoms using the Internalized Shame Scale (ISS) and the Post-Event Rumination Scale (PERS), and VR sickness using the Simulator Sickness Questionnaire (SSQ) during 4 VR sessions (#1, #2, #4, and #6). Logistic regression, random forest, and naïve Bayes classification classified and predicted the severity groups in the ISS, PERS, and SSQ subdomains based on in situ autonomic physiological signal data.

RESULTS

The severity of SAD was predicted with 3 machine learning models. According to the F1 score, the highest prediction performance among each domain for severity was determined. The F1 score of the ISS mistake anxiety subdomain was 0.8421 using the logistic regression model, that of the PERS positive subdomain was 0.7619 using the naïve Bayes classifier, and that of total VR sickness was 0.7059 using the random forest model.

CONCLUSIONS

This study could predict specific anxiety symptoms and VR sickness during VR intervention by autonomic physiological signals alone in real time. Machine learning models can predict the severe and nonsevere psychological states of individuals based on in situ physiological signal data during VR interventions for real-time interactive services. These models can support the diagnosis of specific anxiety symptoms and VR sickness with minimal participant bias.

Preliminary Study of Efficacy and Safety of Self-Administered Virtual Exposure Therapy for Social Anxiety Disorder vs. Cognitive-Behavioral Therapy

Social anxiety disorder (SAD) is one of the most frequent mental disorders. Exposure to virtual reality can be a solution complementing standard CBT (cognitive-behavioral therapy) or can be used as an independent therapeutic tool. The study’s objective was to assess the safety and efficacy of using self-administered virtual reality exposure vs. CBT and CBT with virtual exposure. We assessed the efficacy of the applied intervention with the Leibowitz Social Anxiety Scale (LSAS). We compared three groups: CBT (n = 25), CBT + VR (n = 29), and self-administered therapy without aid of a therapist (n = 19). The results indicated that all three groups showed changes on the LSAS. The simple effect analysis showed that there were no differences between experimental conditions at T0 (session 1) and T1 (session 9) and that the only significant difference occurred at T2 (session 14). The pairwise comparisons showed that the participants in the VR condition scored higher on the LSAS score during the measurement at T2 than participants in CBT condition. Our study has several limitations. The presented initial study shows that the methods of CBT for social anxiety used so far are also effective, while the VR tool for self-therapy requires further research.

The effect of virtual reality therapy and counseling on students' public speaking anxiety

Background and Aims

One of the barriers to effective communication between speaker and listeners is public speaking anxiety (PSA). Over recent years, PSA has become common among students as the most widespread social anxiety (SA). Virtual reality (VR) and counseling therapy help reduce PSA. Therefore, the present study aimed to investigate the effect of VR therapy and counseling on students' PSA and SA.

Methods

This quasi-experimental study was conducted on 30 students at three levels of undergraduate, postgraduate, and PhD at Kerman University of Medical Sciences and Shiraz University of Medical Sciences (15 students in the intervention group and 15 in the control group). The intervention group observed four virtual classroom scenarios in a 30-min session, and the control group attended a 90-min group counseling session. Data were collected using by Personal Report of Public Speaking Anxiety, Liebowitz Social Anxiety Scale, and Igroup Presence Questionnaire. The data analysis was done using SPSS version 21. Descriptive analysis (frequency and percentage, mean, standard deviation, and quartiles) and analytical tests (paired t-test and independent t-test) were used to analyze the data.

Results

The results showed that VR and counseling did not affect SA scores and statistical differences before and after the intervention were not statistically significant. However, VR and counseling reduced PSA. The mean of IPQ/IGP (physical presence) was 63.73. The participants' SA means (93.76) were higher than the mean PSA (73.4).

Conclusions

VR and counseling did not affect students' SA, but they reduced PSA. If the intervention duration in future studies are longer, the effect of VR and counseling on reducing SA is likely to become more apparent.

PROTOCOL: Effects of virtual reality exposure therapy versus in vivo exposure in treating social anxiety disorder in adults: A systematic review and meta-analysis

This is the protocol for a Campbell systematic review. The objectives are as follows: (a) to quantify the effect sizes for virtual reality exposure therapy (VRET) in the treatment of social anxiety disorder (SAD), targeting primary social anxiety symptoms, comorbid anxiety and depression symptoms and improvements in quality of life, when compared to WL, information control, care-as-usual and placebo; (b) to compare VRET to in vivo cognitive and cognitive-behavioral interventions in treating SAD, at posttest and follow-up, using between-group design; (c) to identify the key features which are linked to beneficial outcomes in the two formats in treating SAD and (d) to collect and interpret information on differences in treatment uptake, adherence and attrition, as well as clinical significance and therapist-time in both treatment formats.

The Use of Videogames and Virtual Reality for the Assessment of Anxiety and Depression: A Scoping Review

This study provides a comprehensive review about the use of videogames and virtual reality (VR) for the assessment of anxiety and depression. This review aimed to answer the research question of the viability of games and VR for the assessment of anxiety and depression. An extensive literature search spanning across several databases published since the year 2000 returned a total of 4566 records. Based on the eligibility criteria, the screening process resulted in the selection of 10 articles for the final review. Equal number of studies utilized games (n = 5) and VR. Three studies made use of machine learning techniques. Only two were found to be clinical studies. An interesting finding was that the studies that focused on anxiety disorders relied mostly on VR, whereas those focused on depression disorders relied mostly on the use of videogames for the assessment. Majority of studies reported encouraging findings that support the use of games or VR for the assessment of anxiety and depression. This study identified potential digital biomarkers or correlates of anxiety and depression that may guide researchers in the design process. It is necessary to highlight that researchers should consider consultation with trained mental health experts, while designing such assessments to ensure safety and privacy. However, due to limited number of articles as well as lack of clinical studies, more clinical evidence is required to strongly support this notion of using videogames or VR as assessment tools for anxiety and depression.

Virtual Reality Technology as an Educational and Intervention Tool for Children with Autism Spectrum Disorder: Current Perspectives and Future Directions

The worldwide rising trend of autism spectrum disorder (ASD) calls for innovative and efficacious techniques for assessment and treatment. Virtual reality (VR) technology gains theoretical support from rehabilitation and pedagogical theories and offers a variety of capabilities in educational and interventional contexts with affordable products. VR is attracting increasing attention in the medical and healthcare industry, as it provides fully interactive three-dimensional simulations of real-world settings and social situations, which are particularly suitable for cognitive and performance training, including social and interaction skills. This review article offers a summary of current perspectives and evidence-based VR applications for children with ASD, with a primary focus on social communication, including social functioning, emotion recognition, and speech and language. Technology- and design-related limitations, as well as disputes over the application of VR to autism research and therapy, are discussed, and future directions of this emerging field are highlighted with regards to application expansion and improvement, technology enhancement, linguistic diversity, and the development of theoretical models and brain-based research.

Virtual Reality Behavioral Activation for Adults With Major Depressive Disorder: Feasibility Randomized Controlled Trial

BACKGROUND

Major depressive disorder (MDD) is a global crisis with increasing incidence and prevalence. There are many established evidence-based psychotherapies (EBPs) for depression, but numerous barriers still exist; most notably, access and dissemination. Virtual reality (VR) may offer some solutions to existing constraints of EBPs for MDD.

OBJECTIVE

We aimed to examine the feasibility, acceptability, and tolerability of using VR as a method of delivering behavioral activation (BA) for adults diagnosed with MDD during a global pandemic and to explore for signs of clinical efficacy by comparing VR-enhanced BA (VR BA) to a standard BA treatment and a treatment as usual control group for individuals diagnosed with MDD.

METHODS

A feasibility trial using a 3-armed, unblinded, randomized controlled pilot design was conducted. The study took place remotely via Zoom telehealth visits between April 8, 2020, and January 15, 2021. This study used a 3-week, 4-session protocol in which VR BA participants used a VR headset to complete their BA homework. Feasibility was measured using dropout rates, serious adverse events, completion of homework, an adapted telepresence scale, the Simulator Sickness Questionnaire, the Brief Agitation Measure, and an adapted Technology Acceptance Model. Efficacy was assessed using the Patient Health Questionnaire-9.

RESULTS

Of the 35 participants assessed for eligibility, 13 (37%) were randomized into VR BA (n=5, 38%), traditional BA (n=4, 31%), or a treatment as usual control (n=4, 31%). The mean age of the 13 participants (5/13, 38% male; 7/13, 54% female; and 1/13, 8% nonbinary or third gender) was 35.4 (SD 12.3) years. This study demonstrated VR BA feasibility in participants with MDD through documented high levels of acceptability and tolerability while engaging in VR-induced pleasurable activities in conjunction with a brief BA protocol. No adverse events were reported. This study also illustrated that VR BA may have potential clinical utility for treating MDD, as the average VR BA participant's clinical severity decreased by 5.67 points, signifying a clinically meaningful change in severity from a moderate to a mild level of depression as per the Patient Health Questionnaire-9 score.

CONCLUSIONS

The findings of this study demonstrate that VR BA is safe and feasible to explore for the treatment of MDD. This study documented evidence that VR BA may be efficacious and justifies further examination in an adequately powered randomized controlled trial. This pilot study highlights the potential utility that VR technology may offer patients with MDD, especially those who have difficulty accessing real-world pleasant activities. In addition, for those having difficulty accessing care, VR BA could be adapted as a first step to help people improve their mood and increase their motivation while waiting to connect with a health care professional for other EBPs.

Neural effects of a short-term virtual reality self-training program to reduce social anxiety

BACKGROUND

Social anxiety disorder (SAD) is characterized by anxiety regarding social situations, avoidance of external social stimuli, and negative self-beliefs. Virtual reality self-training (VRS) at home may be a good interim modality for reducing social fears before formal treatment. This study aimed to find neurobiological evidence for the therapeutic effect of VRS.

METHODS

Fifty-two patients with SAD were randomly assigned to a VRS or waiting list (WL) group. The VRS group received an eight-session VRS program for 2 weeks, whereas the WL group received no intervention. Clinical assessments and functional magnetic resonance imaging scanning with the distress and speech evaluation tasks were repeatedly performed at baseline and after 3 weeks.

RESULTS

The post-VRS assessment showed significantly decreased anxiety and avoidance scores, distress index, and negative evaluation index for 'self', but no change in the negative evaluation index for 'other'. Patients showed significant responses to the distress task in various regions, including both sides of the prefrontal regions, occipital regions, insula, and thalamus, and to the speech evaluation task in the bilateral anterior cingulate cortex. Among these, significant neuronal changes after VRS were observed only in the right lingual gyrus and left thalamus.

CONCLUSIONS

VRS-induced improvements in the ability to pay attention to social stimuli without avoidance and even positively modulate emotional cues are based on functional changes in the visual cortices and thalamus. Based on these short-term neuronal changes, VRS can be a first intervention option for individuals with SAD who avoid society or are reluctant to receive formal treatment.

Are Extended Reality Interventions Effective in Helping Autistic Children to Enhance Their Social Skills? A Systematic Review

Autistic children’s social skills do not always align with those of their neurotypical peers and research suggests that this can negatively impact quality of life. This review aimed to assess the effectiveness of extended reality (XR) interventions in helping autistic children to enhance their social skills. Five electronic databases were systematically searched and seventeen studies were identified. The majority targeted social-emotional reciprocity and were of relatively low quality. There was insufficient evidence to determine whether effects were generalisable, sustained or important to autistic people. Research in this field is in its infancy and evidence of effectiveness should be viewed with caution. Future studies should aim for high-quality, theory-driven research, and involve autistic people to ensure meaningful outcomes.

Effects of Virtual Reality Education on Procedural Pain and Anxiety During Venipuncture in Children: A Randomized Clinical Trial

Background

Venipuncture is one of the most frequent and frightening medical procedures for children. This randomized clinical trial aimed to evaluate whether pre-procedural immersive virtual reality (VR) education could decrease pain and anxiety during venipuncture procedure of children.

Methods

Sixty children scheduled for venipuncture at the phlebotomy unit were randomized into either the control or VR group. Before the procedure, children of the control group received conventional simple verbal instructions, whereas those of the VR group experienced a 4-min VR education regarding venipuncture. The primary outcome was the pain and anxiety of pediatric patients assessed with the children’s hospital of eastern ontario pain scale. Secondary outcomes were parental satisfaction, venipuncture time, repeated procedure and procedural difficulty rated by phlebotomists.

Results

The pain and anxiety score during the procedure was significantly lower in the VR group than in the control group (median [IQR], 6.0 [5.0–7.0] vs. 8.0 [6.0–9.8], P = 0.001). Parental satisfaction about the procedural process were higher in the VR group than in the control group (P = 0.029), and the degree of procedural difficulty was lower in the VR group, compared to the control group (P = 0.026).

Conclusion

The preprocedural VR education significantly reduced pain and anxiety of children and decreased the procedural difficulty of phlebotomists during venipuncture procedure.
