Two case studies from a virtual reality intervention for delusions: feasibility and preliminary evidence

Immersive Virtual Reality Simulation in Forensic Psychiatry and Adjacent Clinical Fields: A Review of Current Assessment and Treatment Methods for Practitioners

Background: Research has indicated that interactive, computerized case simulations using immersive virtual reality (VR) technology may be beneficial in the augmentation of conventional methods of assessment and treatment in forensic psychiatry, primarily through providing an engaging and safe environment in which the user can practice and learn skills and behaviors. However, there does not appear to be an overview of current developments available in the field, which may be an obstacle to clinicians considering the use of VR in their clinical practice. Objectives: Current, clinically relevant assessment and treatment methods applying immersive VR in forensic or adjacent clinical settings, were analyzed. Methods: This review surveyed the practical use of immersive VR in forensic psychiatry and relevant adjacent psychiatric and forensic fields from 2016 to 2020 and was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results: Out of the 1,105 journal articles screened, 14 met criteria for inclusion. Four articles described VR interventions directly addressing forensic psychiatric settings (treatment of general aggression and assessment of sexual offenders against children). The majority of the remaining articles were in the clinical domain of psychosis treatment. Several interventions were designed as part of comprehensive treatment programs, and others were intended as one-off assessments or paired with pre-existing psychological treatment. The degree to which the VR simulations were individualized to the user appeared to be largely dependent upon the extent of provider input. A variety of research methodologies were used in the included articles and the majority had limitations common to small-scale, non-randomized studies. None of the studies reported serious adverse effects. Discussion: There is a lack of large randomized controlled trials of current assessments or treatments using VR simulation in forensic psychiatry, let alone those with long-term follow-up, showing clear advantages of VR over standard practice. The evidence thus far is insufficient to recommend immediate and large-scale implementation of any one VR intervention, however, several have been shown to be feasible and acceptable to the participants and to provide insights and inspiration for future research and development.

Immersive Virtual Reality in Health Care: Systematic Review of Technology and Disease States

Background

Immersive virtual reality (IVR) presents new possibilities for application in health care. Health care professionals can now immerse their patients in environments to achieve exposure to a specific scene or experience, evoke targeted emotional responses, inspire, or distract from an experience occurring in reality.

Objective

This review aimed to identify patient-focused applications for head-mounted IVR for acute treatment of health conditions and determine the technical specifications of the systems used.

Methods

A systematic review was conducted by searching medical and engineering peer-reviewed literature databases in 2018. The databases included PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Association for Computing Machinery, Institute of Electrical and Electronics Engineers, Scopus, and Web of Science. Search terms relating to health and IVR were used. To be included, studies had to investigate the effectiveness of IVR for acute treatment of a specific health condition. IVR was defined as a head-mounted platform that provides virtual and auditory immersion for the participant and includes a minimum of 3 degrees of orientation tracking. Once identified, data were extracted from articles and aggregated in a narrative review format.

Results

A total of 58 studies were conducted in 19 countries. The studies reported IVR use for 5 main clinical areas: neurological and development (n=10), pain reduction through distraction (n=20), exposure therapy for phobias (n=9), psychological applications (n=14), and others (n=5). Studies were primarily feasibility studies exploring systems and general user acceptance (n=29) and efficacy studies testing clinical effect (n=28).

Conclusions

IVR has a promising future in health care, both in research and commercial realms. As many of the studies examined are still exploring the feasibility of IVR for acute treatment of health conditions, evidence for the effectiveness of IVR is still developing.
