Profiling the Dynamic of Binge Eating Disorder (PRODY-BED)

The goal of this observational study is to explore if different and specific profiles can be identified in adults with binge eating disorder (BED) depending on their additional eating pathology, emotion regulation and executive functions. The main questions it aims to answer are: * Is there different and specific subgroups of patients with BED according to baseline profiles in emotion regulation, executive function and additional eating pathology (including restriction, chaotic eating, grazing and eating on external cues)? * Are subgroups of individuals with BED (based on identified profiles) associated with outcome at end of treatment and follow-up? * What is the trajectories in remission rates of specific symptom dimensions (eating disorder pathology, emotion regulation, executive function, and depressive symptoms) in individuals with BED and is there specific trajectory profiles in these dimensions? * Is early changes in specific symptom dimensions (eating pathology, emotion regulation, executive function, or depression) associated with outcome of BED? Participants will be asked to fill in questionnaires before treatment as usual, 10 weeks into treatment, at end of treatment and at 6- and 12-month follow-up.
