One hundred obese women with a mean age of 39.2 years, and a mean body mass index (BMI) of 35.9 kg/m2 were evaluated before entering a treatment study for weight reduction. According to the results of a structured interview, subjects were divided into four groups: (?) no overeating episodes, (2) episodic overeating episodes without the feeling of loss of control, (3) overeating plus the sense of loss of control (binge eating), and (4) full diagnostic criteria for binge eating disorder (BED). One‐way analyses of variance (ANOVAs) revealed significant positive associations between binge eating and eating/weight‐related characteristics such as a history of frequent weight fluctuations, the amount of time spent dieting, drive for thinness, and a tendency for disinheriting of eating. Furthermore, subjects exhibited more feelings of ineffectiveness, stronger perfectionist attitudes, more impulsivity, less self‐esteem, and less interceptive awareness the more problems with binge eating they reported. The results support the idea that binge eaters might be a distinct subgroup among the obese population, and corroborate the utility of a diagnosis of BED in identifying the most disturbed obese subjects with regard to the variables tested. © 1994 by John Wiley & Sons, Inc.
