Overview
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.

Outcomes
Primary Outcomes
Verbal Rating Scales of food craving (VRS)
Time Frame: Change from the first exploration of virtual rooms to the last exploration (20 minutes)
Evaluate variation in food craving assessed by Verbal Rating Scales (VRS) : self-assessment from 0 to 10 with 0 = "no food craving felt" and 10 = "maximum food craving felt")
Secondary Outcomes
- Verbal Rating Scales of food craving (VRS)(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Heart rate variation(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Pupillometry(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Electro-Dermal Activity(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Variations of the measurements VRS of the food craving and each of the physiological measurements of the food craving(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Variations of the VRS food craving and of the VRS anxiety of the food craving(Change from the start of exploration of each virtual rooms to the end (5 minutes))
- Verbal Rating Scales of anxiety (VRS)(Change from the start of exploration of each virtual rooms to the end (5 minutes))
