Validation Study of a Rapid Screening Test of Food Addiction in Patients Suffering From Obesity and Healthy Volunteer

Food addiction (FA) is a behavioral addiction characterized by a high consumption of palatable foods, which markedly activate the reward system, despite adverse consequences. FA was first described in 1956 but remains controversial. The Yale Food Addiction Scale (YFAS), developed by Gearhardt et al. in 2009, is currently regarded as the "Gold Standard" for FA screening. In a previous study, we established a Food Addiction Screening Test using artificial intelligence. The main objective of the present study is to validate the sensitivity, specificity and precision for FA diagnosis in a sample of patient suffering from obesity and healthy volunteers.
