Compuls-BED-Severity

* Binge Eating Disorder (BED) has been fairly recently introduced into the Diagnostic and Statistical Manual 5 psychiatric classification and its severity criteria are still not well established. * Moreover, it remains unclear whether BED is associated with greater metabolic severity or more somatic comorbidities, especially in obesity. * Improved BED severity staging could lead to a better definition of management strategies and , therefore, facilitate screening and care.

The investigators' hypothesis is that an improved assessment of the impulsivity-compulsivity spectrum, emotional regulation, attentional impairment and somatic or psychiatric comorbidities will result in a better distinction between the severe form of BED (e.g., highly impulsive and somatically complicated) from milder form (e.g., more compulsive and less somatically complicated).
