The present study compared threshold, subthreshold BED (Binge Eating Disorder), and subjects without BED in a population of overweight/obese individuals seeking weight loss treatment, considering the sociodemografic features, the eating specific and general psychopathology, the organic and psychiatric comorbidity, the quality of life, and the emotional eating as a trigger factor for binge eating. Four hundred thirty eight overweight subjects seeking weight loss treatment have been evaluated by means of a clinical interview (SCID I), and different self-reported questionnaires, assessing the eating specific and general psychopathology. One hundred five subjects (24% of the sample) fulfilled the DSM-IV criteria of BED, 146 (33.3%) fulfilled the criteria of subthreshold BED, and 187 (42.7%) subjects were diagnosed overweight non-BED. The groups did not differ in terms of psychiatric comorbidity, diet attempts, quality of life, and psychopathology, while the presence of binge eating was associated to higher eating, weight, and shape concerns. Emotional eating was positively correlated to the presence/severity of binge eating.
