Project description:ObjectiveFour randomized controlled trials revealed that virtual-reality job interview training (VR-JIT) improved interviewing skills and the odds of obtaining a job offer among trainees with severe mental illness or autism spectrum disorder. This study assessed whether postintervention interviewing skills mediated the relationship between completion of virtual interviews and receiving job offers by six-month follow-up.MethodsVR-JIT trainees (N=79) completed pre- and posttest mock interviews and a brief survey approximately six months later to assess whether they received a job offer.ResultsAs hypothesized, analyses indicated that the number of completed virtual interviews predicted greater posttest interviewing skills (β=.20, 95% posterior credible interval [PCI]=.08-.33), which in turn predicted trainees' obtaining a job offer (β=.28, 95% PCI=.01-.53).ConclusionsVR-JIT may provide a mechanism of action that helps trainees with various psychiatric diagnoses obtain job offers in the community. Future research can evaluate the community-based effectiveness of this novel intervention.

Project description:ObjectiveEmployment rates among individuals with serious mental illness may be improved by engagement in the individual placement and support (IPS) model of supported employment. Results from a recent randomized controlled trial (RCT) indicate that virtual reality job interview training (VR-JIT) improves employment rates among individuals with serious mental illness who have been actively engaged in IPS for at least 90 days. This study reports on an initial implementation evaluation of VR-JIT during the RCT in a community mental health agency.MethodsA sequential, complementary mixed-methods design included use of qualitative data to improve understanding of quantitative findings. Thirteen IPS staff trained to lead VR-JIT implementation completed VR-JIT acceptability, appropriateness, and feasibility surveys. Participants randomly assigned to IPS with VR-JIT completed acceptability (N=42) and usability (N=28) surveys after implementation. The authors also conducted five focus groups with IPS staff (N=11) and VR-JIT recipients (N=13) and semistructured interviews with IPS staff (N=9) and VR-JIT recipients (N=4), followed by an integrated analysis process.ResultsQuantitative results suggest that IPS staff found VR-JIT to be highly acceptable, appropriate for integration with IPS, and feasible for delivery. VR-JIT was highly acceptable to recipients. Qualitative results add important context to the quantitative findings, including benefits of VR-JIT for IPS staff as well as adaptations for delivering technology-based interventions to individuals with serious mental illness.ConclusionsThese qualitative and quantitative findings are consistent with each other and were influenced by VR-JIT's adaptability and perceived benefits. Tailoring VR-JIT instruction and delivery to individuals with serious mental illness may help optimize VR-JIT implementation within IPS.

Project description:BackgroundVirtual reality can play an important role during the COVID-19 pandemic in the health care sector. This technology has the potential to supplement the traditional in-hospital medical training and treatment, and may increase access to training and therapies in various health care settings.ObjectiveThis systematic review aimed to describe the literature on health care-targeted virtual reality applications during the COVID-19 crisis.MethodsWe conducted a systematic search of the literature on the PsycINFO, Web of Science, and MEDLINE databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The search string was as follows: "[(virtual reality)] AND [(COVID-19) OR (coronavirus) OR (SARS-CoV-2) OR (healthcare)]." Papers published in English after December 2019 in peer-reviewed journals were selected and subjected to the inclusion and exclusion criteria. We used the Mixed Methods Appraisal Tool to assess the quality of studies and the risk of bias.ResultsThirty-nine studies met the inclusion criteria. Seventeen studies showed the usefulness of virtual reality during the COVID-19 crisis for reducing stress, anxiety, depression, and pain, and promoting physical activity. Twenty-two studies revealed that virtual reality was a helpful learning and training tool during the COVID-19 crisis in several areas, including emergency medicine, nursing, and pediatrics. This technology was also used as an educational tool for increasing public understanding of the COVID-19 pandemic. Different levels of immersion (ie, immersive and desktop virtual reality), types of head-mounted displays (ie, PC-based, mobile, and standalone), and content (ie, 360° videos and photos, virtual environments, virtual reality video games, and embodied virtual agents) have been successfully used. Virtual reality was helpful in both face-to-face and remote trials.ConclusionsVirtual reality has been applied frequently in medicine during the COVID-19 pandemic, with positive effects for treating several health conditions and for medical education and training. Some barriers need to be overcome for the broader adoption of virtual reality in the health care panorama.Trial registrationInternational Platform of Registered Systematic Review and Meta-analysis Protocols (INPLASY) INPLASY202190108; https://inplasy.com/inplasy-2021-9-0108/.

Project description:BackgroundImmersive virtual reality (VR) with head-mounted display was used to determine if clinical interview simulation could reduce the anxiety levels of first-year occupational therapy (OT) students as they prepared for upcoming Objective Structured Clinical Examinations (OSCEs). Anxiety among health science students is a potential problem that may diminish their performance during OSCEs. This investigation aimed to fill the gap in the literature regarding the effectiveness of VR to reduce anxiety in OT students.ObjectiveThis investigation aimed to uncover the effectiveness of immersive VR in reducing state anxiety in OT students who were preparing for OSCEs.MethodsA prospective, experimental, nonrandomized controlled trial compared levels of state anxiety, test anxiety, and academic self-efficacy in two groups of first-year OT students; these levels were measured at four different time points by self-reported psychometric scales, analyzed with a mixed factorial analysis of variance (ANOVA). Members of Phase 1 (NoVR) were not exposed to the VR simulation and acted as a control group for members of Phase 2 (YesVR), who were exposed to the VR simulation. VR simulation featured a virtual clinic and a standardized patient who students could interview in natural language. Measures of student study strategies and previous experience with VR were also recorded.ResultsA total of 49 participants-29 in the NoVR group and 20 in the YesVR group-showed that state anxiety had a rise-then-fall trend, peaking at the time point just before the OSCE. At that point, the YesVR students showed significantly less state anxiety than did the NoVR students (t46.19=2.34, P=.02, Cohen d=0.65, ηp2=0.105). The mean difference was 6.78 units (95% CI 0.96-12.61). In similar trends for both groups, student test anxiety remained relatively static across the time points, while academic self-efficacy continually increased. A moderate positive correlation was found for total time spent studying and peak state anxiety (NoVR r=.46, n=28, P=.01; YesVR r=.52, n=19, P=.02).ConclusionsThis investigation shows evidence of immersive VR's capability to reduce state anxiety in OT students preparing for clinical practical exams. Immersive VR simulation, used for the reduction of anxiety in health science students, can potentially lead to a future of positive mental health change from the virtual to the real world.

Project description:ObjectiveIndividuals with severe mental illness have low employment rates, and the job interview presents a critical barrier for them to obtain competitive employment. Prior randomized controlled trials (RCTs) indicated that virtual reality job interview training (VR-JIT) improved job interviewing skills among trainees. This study assessed whether VR-JIT participation was associated with greater odds of receiving job offers in the six-months after completion of training.MethodsTo assess the efficacy of VR-JIT, trainees (N=39) in the method and a comparison group (N=12) completed a brief survey approximately six months after participating in the RCTs. Primary vocational outcome measures included receiving a job offer and number of weeks searching for employment.ResultsA larger proportion of trainees than comparison participants received a job offer (51% versus 25%, respectively). Trainees were more likely to receive a job offer than comparison participants (odds ratio=9.64, p=.02) after analyses accounted for cognition, recency of last job, and diagnosis. Trainees had greater odds of receiving a job offer for each completed VR-JIT trial (odds ratio=1.41, p=.04), and a greater number of completed VR-JIT trials predicted fewer weeks of searching for employment (β=-.74, p=.02).ConclusionsResults provide preliminary support that VR-JIT is a promising intervention associated with enhanced vocational outcomes among individuals with severe mental illness. Given that participants had minimal access to standardized vocational services, future research could evaluate the effectiveness of VR-JIT among individuals with and without access to standardized vocational services as well as evaluate strategies to implement VR-JIT within a large community mental health service provider.

Project description:BackgroundIndividuals with schizophrenia have low employment rates and the job interview presents a critical barrier for them to obtain employment. Virtual reality training has demonstrated efficacy at improving interview skills and employment outcomes among multiple clinical populations. However, the effects of this training on individuals with schizophrenia are unknown. This study evaluated the efficacy of virtual reality job interview training (VR-JIT) at improving job interview skills and employment outcomes among individuals with schizophrenia in a small randomized controlled trial (n=21 VR-JIT trainees, n=11 waitlist controls).MethodsTrainees completed up to 10h of virtual interviews using VR-JIT, while controls received services as usual. Primary outcome measures included two pre-test and two post-test video-recorded role-play interviews scored by blinded raters with expertise in human resources and self-reported interviewing self-confidence. Six-month follow-up data on employment outcomes were collected.ResultsTrainees reported that the intervention was easy-to-use, helpful, and prepared them for future interviews. Trainees demonstrated increased role-play scores between pre-test and post-test while controls did not (p=0.001). After accounting for neurocognition and months since prior employment, trainees had greater odds of receiving a job offer by 6month follow-up compared to controls (OR: 8.73, p=0.04) and more training was associated with fewer weeks until receiving a job offer (r=-0.63, p<0.001).ConclusionsResults suggest that VR-JIT is acceptable to trainees and may be efficacious for improving job interview skills in individuals with schizophrenia. Moreover, trainees had greater odds of receiving a job offer by 6-month follow-up. Future studies could evaluate the effectiveness of VR-JIT within community-based services.

Project description: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.

Project description:Children must often endure painful procedures as part of their treatment for various medical conditions. Those with chronic pain endure frequent or constant discomfort in their daily lives, sometimes severely limiting their physical capacities. With the advent of affordable consumer-grade equipment, clinicians have access to a promising and engaging intervention for pediatric pain, both acute and chronic. In addition to providing relief from acute and procedural pain, virtual reality (VR) may also help to provide a corrective psychological and physiological environment to facilitate rehabilitation for pediatric patients suffering from chronic pain. The special qualities of VR such as presence, interactivity, customization, social interaction, and embodiment allow it to be accepted by children and adolescents and incorporated successfully into their existing medical therapies. However, the powerful and transformative nature of many VR experiences may also pose some risks and should be utilized with caution. In this paper, we review recent literature in pediatric virtual reality for procedural pain and anxiety, acute and chronic pain, and some rehabilitation applications. We also discuss the practical considerations of using VR in pediatric care, and offer specific suggestions and information for clinicians wishing to adopt these engaging therapies into their daily clinical practice.
