Research has revealed that Virtual Reality (VR) technology can have a significant impact on the validity of remote health appointments for those with eating disorders, through a process called Virtual Reality Exposure Therapy (VRET).

In a recent study published in the Human-Computer Interaction Journal, participants and therapists were fitted with VR Head-Mounted Displays and introduced to each other within the VR system. Participants would then customise their virtual avatar according to their look (body shape and size, skin tone and hair colour and shape). Participant and therapist were then “teleported” to two Virtual Environment interventions for several discussions, building up to the Mirror Exposure.

Mirror Exposure involves confrontation in a mirror with ones’ shape and body. In this environment, the participant faces the virtual avatar they customised to match their own physical body. Here, they were again able to adjust body shapes using virtual sliders, change clothing, skin tone, as well as hair style and colour. Clothing was then gradually reduced until the participant’s avatar was in their virtual underwear.

The participant was then asked to examine each part of their body and perform adjustments while describing their feelings, thoughts and concerns with the therapist, leading to virtual exposure therapy for the patient to their body shape and size through the customised avatar.

The study found that the avatar of the therapist was vital to the participant. The cartoonish avatar facilitated greater openness from participants, whilst therapist avatars in human-form represented the idea of negative judgement.

In post-session interviews, participants noted the lack of fear of judgement as enabling them to commit to the session’s aims.

Dr Jim Ang, Senior Lecturer in Multimedia/Digital Systems and Supervisor of the study said: ‘The potential of Virtual Reality being used in addressing health issues with patients, remotely and without the issue of potential judgement, is for VR to be utilised throughout the health sector. Without the issue of judgement, which people can fear in advance of even seeking medical advice, VR can give people the confidence to engage with and embrace medical advice. In terms of the technical capabilities, the potential for VR to aid in remote non-contact medical appointments between patients and practitioners is huge, particularly given the current pandemic.’

Dr Maria Matsangidou, Research Associate at RISE Ltd and Experimental Researcher of the study said: ‘Multi-User Virtual Reality is an innovative medium for psychotherapeutic interventions that allows for the physical separation of therapist and patient, providing thus more ‘comfortable’ openness by the patients.

Exposure to patient worries about body shape and size may exhibit anxious reactions, but through remote exposure therapy this can elicit new learning that helps the patient to shape new experiences.’
