5. Study Description

Brief Summary
Food craving is a major therapeutic issue in Eating Disorders with binge eating: the Bulimia Nervosa and the Binge Eating Disorder (BED). Food craving is linked to compulsive eating and its apprehension is currently based on classic Cognitive and Behavioural Therapies (CBT). However, it remains difficult to induce in therapy and a significant number of patients do not respond to classic CBTs. The development of exposure scenarios for CBT in virtual reality (VR) has allowed a gain in efficacy and in particular therapeutic effects lasting longer after treatment. Nevertheless, the stimuli used are often simple food visuals and insufficiently consider the many factors influencing food craving (physical, psychological, socio-environmental...) and VR immersion is still limited by the use of 3D laptops (fixed) rather than wireless headsets.
Detailed Description
Eating Disorders-specialized clinicians from Saint-Etienne University Hospital Center (CHU) and VR-specialized engineers from National School of Engineering of Saint-Etienne (ENISE) therefore collaborated in the creation of ReVBED, a VR-based exposure scenario for CBT for the induction of food craving in eating disorders with binge eating. ReVBED offers successive exposures to multimodal stimuli in a coherent scenario and in an immersive virtual environment via a wireless VR headset. Our first objective is to validate the effectiveness of our scenario in inducing food craving in patients with bulimia and BED.

Intervention Description
ReVBED is a VR-based exposure scenario for CBT for the induction of food craving in patients with bulimia nervosa and binge eating disorder. The use of ReVBED requires no VR experience and only generic and commonly used virtual reality tools (a computer with VR software, a wireless virtual reality headset, two controllers and headphones), all with a CE mark, allowing its users to move in and interact with a specially designed virtual environment. This exhibit scenario takes place in a VR environment built to represent a standard apartment consisting of four exhibit rooms (a bedroom, a teenager's bedroom, a living room and a kitchen) in which the ReVBED user moves sequentially through the scenario. In each room, specific cues of craving are displayed. These cues are not only visual, but also audio, emotional and socio-environmental. A central hall connects the other rooms and serves as a safe place for debriefing, where measures such as craving are assessed.
