The Body Image Virtual Reality Assessment (BIVRA): Measuring the body representation through virtual reality

Our physical and psychological well-being is significantly influenced by how we perceive our body, in addition to our thoughts and emotions associated with it. Dysfunctional body perceptions and attitudes play a key role in the development and maintenance of severe conditions such as eating disorders in both males and females. Given its relevance, some attempts have been made to improve body image assessment methods in terms of perceptual accuracy and body satisfaction taking advantage of technological advances such as virtual reality. However, existing applications have mainly focused on women and clinical conditions. In this study, we presented the Body Image Virtual Reality Assessment (BIVRA), a virtual reality figure rating scale to assess body image in both male and female subjects. We tested BIVRA's ability to measure perceptual accuracy and compared its results with a standardized body satisfaction questionnaire. Additionally, we investigated gender differences. BIVRA was found to be effective in assessing body image. We observed that a perceptually based task successfully captured both low and high levels of body representations, shedding light on the significant gender differences. The association between BIVRA and the body satisfaction questionnaires was moderated by gender, with a stronger association for women. While further validation of BIVRA is needed to fully exploit its potential, our results suggest that the integration of virtual reality into the assessment of body image and related disorders may significantly enhance our understanding of individuals struggling with body image issues and has the potential to advance current methods and techniques.

Feasibility of using virtual reality in geriatric psychiatry

OBJECTIVES

Virtual Reality-based interventions have become an important element of digital mental health, offering accessible and scalable treatment options. However, studies on VR-based approaches in elderly patients are scarce. This explorative study examined the feasibility of using Virtual Reality (VR) for elderly patients with psychiatric illness, focusing on the sense of presence as the primary outcome.

METHODS

The study included N = 30 patients between the ages of 59-92 years who were currently in geriatric psychiatric inpatient and day clinic treatment. Participants were assessed before, during and after a relaxing ten-minute VR experience. Attitude towards digital media and VR, subjective digital competence, and previous experience were examined using questionnaires. Motion sickness was measured repeatedly during the VR experience using the Fast Motion Sickness Scale (FMS). Patients rated their motion sickness and their general well-being in the virtual environment. Sense of presence in the virtual environment was quantified with the Igroup Presence Questionnaire (IPQ).

RESULTS

Participants reported a notable sense of presence (M = 0.41 ± 1.4) in the virtual environment, particularly in terms of spatial presence. Motion sickness was reported by a minority of patients. Three patients terminated the VR application before it was finished. The average well-being during the VR experience was reported as high (70/100). Sense of presence and motion sickness showed a significant negative correlation. Presence, motion sickness and well-being were not significantly correlated with age, nor did they differ significantly between groups.

CONCLUSIONS

This study underscores the potential of VR-based experiences in the treatment of elderly psychiatric patients and highlights their willingness and ability to engage with VR technology. While the results are promising, future research should explore more interactive VR scenarios and assess their safety and feasibility in elderly populations.
