This study used a 6- to 22-day experience-sampling procedure to test for hypersensitivity to social interactions in bulimic individuals. Ratings on daily social interactions, self-concepts, moods, and eating behaviors from 55 actively bulimic, 18 formerly bulimic, and 31 noneating-disordered women were obtained. Hierarchical linear modeling analyses showed negative social interactions to be associated with significant increases in self-criticism (SC) and deteriorations in mood in all participants. However, bulimic participants (active or in remission) showed larger increases in SC following negative social interactions than did normal eaters (and thus seemed to be hypersensitive to interpersonal experiences). Additional analyses indicated that binge episodes tended to be preceded by poorer than average social experiences, self-concepts, and moods and followed by deteriorations in self-concept, mood, and social perception. The authors discuss possible perpetuating influences of interpersonal sensitivity in bulimic syndromes.

Introduction: Many theories attribute anorexia and bulimia nervosa to "pathological narcissism," but this conception has not been adequately evaluated., Method: We compared the scores of 90 eating disorder (ED) sufferers (23 anorexic restricters, 14 anorexic bingers, and 53 bulimics) with those of 36 psychiatric-control (PC) and 54 normal-control (NC) females on validated self-report scales measuring Narcissism, Affective Instability, Stimulus Seeking, Compulsivity, and Restricted Expression., Results: Narcissism scores of ED patients (whether restricters or bingers/purgers) consistently exceeded those of the PC and NC cases, suggesting that Narcissism does indeed load more heavily in the EDs than in other psychiatric disturbances. Conversely, Affective Instability was characteristic of all clinical cases (i.e., of EDs and PCs), Restricted Expression and Compulsivity were characteristic of restricters, and Stimulus Seeking was characteristic of bingers/purgers., Discussion: Results are consistent with the notion that different ED variants may reflect subtype-specific temperaments and/or adaptive styles acting-upon shared underlying narcissistic disturbances.
