Abstract Objective To explore similarities and differences in clinical and personality variables across three groups: binge eating disorder (BED), bulimia nervosa‐purging type (BN‐P), and bulimia nervosa‐non purging type (BN‐NP). Method The participants were 102 female eating disorders patients (34 BED, 34 BN‐P, and 34 BN‐NP) consecutively admitted to the eating disorders unit, at the University Hospital of Bellvitge, and diagnosed according to DSM‐IV criteria. Results BED patients were older, and more likely to have personal and family history of obesity. A gradient in psychopathological scores emerged with BN‐P patients having higher pathological scores on the SCL‐90‐R, followed by BN‐NP and BED patients. No statistically significant differences were observed in personality traits. Discussion Our data supported that eating disorders (namely BED, BN‐NP, and BN‐P) followed a linear trend in general psychopathology. Whereas personality may represent a shared vulnerability factor, differences in clinical severity suggest there to be a continuum with BN‐P being the most severe and BED being the least severe. © 2010 by Wiley Periodicals, Inc.
