Miller AE, et al. - Researchers aimed to examine how borderline personality disorder (BPD) symptoms are related to symptoms of bulimia nervosa (BN) and anorexia nervosa (AN), including the differential impact of the nine BPD symptoms on BN vs AN. Among 208 adolescent psychiatric inpatients, more strong correlation of BPD symptoms with self-reported BN vs AN symptoms was observed. Individuals who endorsed unstable relationships, affective instability, emptiness, identity disturbance, inappropriate anger, dissociation/paranoia, and suicidal behavior showed greater BN and AN symptoms. When impulsivity was endorsed higher BN symptoms, but not AN symptoms, were noted. Neither BN nor AN showed correlation to avoiding abandonment. Substantially larger associations of affective instability, impulsivity, and anger with BN compared to AN were observed, while more strongly relation of identity disturbance with AN than BN was observed. These observations may aid in targeting specific BPD symptoms to help prevent and decrease co-occurring eating disorders and BPD and the negative consequences associated with this comorbidity.
