Pre-therapeutic Validation of the Virtual Reality-based Exposure Scenario for CBT "ReVBED" for the Induction of Food Craving in Patients With Bulimia and Binge Eating Disorder (BED)

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.
