Abstract
Although common characteristics have been highlighted between different Eating Disorders (ED), most existing classifications continue to consider them as separated diagnoses and to put forward their differences. The aim of this study was to verify if similarities and differences in terms of psychosocial functioning could be found between five groups of individuals, who reported binge eating behaviors. Nine hundred and seventy-eight patients consulting for ED problems in three different private clinics completed online questionnaires after a first psychological consultation. Based on their responses to the Eating Disorder Examination Questionnaire (EDE-Q6), participants were included in five clinical groups: bulimia nervosa, binge eating disorder, anorexia nervosa binge eating/purging type, other specified feeding or eating disorders, and no binge eating behaviors. They filled out online questionnaires assessing perfectionism, self-esteem, body esteem, depression, anxiety, alexithymia, fear of negative appearance, and weight stigmatization. Significant differences were observed between the ED groups and the no binge eating behaviors’ group. Although the various ED subtypes did not differ on any of the variables studied, some clinical profiles seemed to emerge. The results support a transdiagnostic and dimensional approach to ED.
