Eating disorders (EDBs) are mental disorders with a great impact on the lives of individuals as well as a great cost imposed on society. The treatments currently available rely on different forms of psychotherapies with an unsatisfactory response rate as well as a considerable relapse rate . One of the reasons underlying the low success of available therapeutic modalities would be the heterogeneity of the clinical presentation of EDs, making their classification and the personalization of their treatment more difficult.The investigators hypothesize that a secondarily dimensional classification approach (respecting the categorical classification currently in use) of EDs based on the different dimensions disturbed in these disorders as well as in their comorbidities, would better represent their nosographic reality, which could provide patients with more personalized and potentially more effective care.
