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.
Patient with an eating disorder according to DSM-V criteria
Patient aged from 15 to 65 years

Patient affiliated to a French social security system
Patient in an unstable somatic state (eg severe metabolic disorder making impossible or unreliable neuropsychological assessments)

Eating Disorders Inventory (EDI-2)
self-questionnaire of 91 items aimed at evaluating attitudes and behaviors related to food and allowing the identification of 11 dimensions: search for thinness, bulimia, body dissatisfaction, inefficiency, perfectionism, interpersonal distrust, interoceptive awareness, fear of maturity , asceticism, impulse control, social insecurity. The higher the subscore, the more severely impaired the dimension concerned is.
Eating Disorder Examination Questionnaire (EDE-Q)
Self-reported version of the gold-standard clinical interview for ED assessing the intensity of eating symptoms over the last 28 days. A total score as well as 4 sub-scores (restriction, diet, weight, shape) varying from 0 to 6 are thus obtained.
Symptomatic dimensions of Eating Disorder Examination Questionnaire (EDEQ)
Self-reported version of the gold-standard clinical interview for ED assessing the intensity of eating symptoms over the last 28 days. A total score as well as 4 sub-scores (restriction, diet, weight, shape) varying from 0 to 6 are thus obtained.
Body Shape Questionnaire (BSAQ-34)
self-questionnaire of 34 items assessing body dissatisfaction and in particular four dimensions: avoidance and social shame of body exposure, body dissatisfaction with the lower parts of the body, use of laxatives and vomiting to reduce body dissatisfaction, maladaptive cognitions and behaviors in order to control weight. The total score ranges from 0 to 204. A score below 80 indicates no excessive body concerns, a score between 80 and 100 indicates mild concerns, between 111 and 140 moderate concerns, and a score above 140 indicates significant concerns
Yale Food Addiction Scale (YFAS)
35-item Likert-type self-questionnaire assessing the difficulty or not in controlling the quantity of food one eats over the past 12 months, using an 8-point scale from "never" to "all days ". This questionnaire assesses clinical distress based on the DSM-5 diagnostic criteria for substance use disorders. Presenting clinically significant suffering and at least 2 diagnostic criteria suggest a food addiction.
Sociocultural Attitudes Towards Appearance Scale (SATAQ-4)
multidimensional self-questionnaire of 22 items rated from 1 (completely disagree) to 5 (completely agree) aimed at assessing the sociocultural influence of the media on appearance. It includes four subscales: pressures, information, internalization relating to athletes and general internalization. The higher the score, the stronger the influence.
