What this Trial Is About
Researchers are investigating the relationship between food craving and cognitive impairments in women diagnosed with bulimia nervosa and binge eating disorder. These eating disorders share similarities with addictive disorders, especially in terms of craving, which is a strong urge to consume certain products. The study aims to understand how craving impacts reflexive, automatic, interoceptive, and metacognitive systems, and how these effects differ between the two eating disorders. The study uses a behavioral approach to induce food craving through exposure to food-related images. Participants include women diagnosed with bulimia nervosa or binge eating disorder. The craving intensity will be measured using a visual analog scale before and after the craving induction. Two main groups are observed: those with binge eating disorder and those with bulimia nervosa. Participants will undergo various assessments lasting about one hour after craving induction, including tests measuring attention, metacognition, and approach-avoidance behavior related to food. Baseline questionnaires will evaluate depression, anxiety, eating disorder symptoms, craving traits and states, emotional regulation, insight, attention control, and body awareness. The study involves comprehensive monitoring of cognitive and emotional responses to craving to better understand these eating disorders.
