Eating disorders are multifactorial disorders currently conceptualized in a biopsychosocial model, but pathophysiology remains relatively unknown, and robust etiological models to guide treatment are therefore lacking. Different endophenotypes and neurocognitive vulnerability factors have been found in eating disorders including decision making abnormalities. The investigators hypothesize that decision making abnormalities are associated with a lower level of functioning and quality of life which could lead to social and interpersonal difficulties. The investigators also hypothesize that these anomalies are associated with a particular clinical profile (more restrictive profile, more hyperactivity, less insight on the disease and desire for care ...).

The investigators will recruit a total of 200 patients with an eating disorder in the university hospital of Montpellier.

Participation consists of a one-day visit with a multidisciplinary assessment. No action is specific to research. This is the usual management of patients with eating disorders addressed to our department.

• Patient with an eating disorder according to DSM-V criteria
• Patient aged from 15 to 65 years
• Patient who performs the day-hospital evaluation
• Patient affiliated to a French social security system
