This study examines the degree to which an eating disorder (ED) is associated with the recurrence and severity of suicide attempts, non-suicidal self-injury, rates of co-occurring Axis I and II disorders, and psychosocial functioning among Borderline Personality Disorder (BPD) outpatients. A group of 135 treatment-seeking women with BPD were assessed using structured clinical interviews. BPD was assessed using the International Personality Disorders Examination, confirmed by the Structured Clinical Interview for DSM-IV (SCID)-II, and Axis I disorders were assessed with the SCID I. A total of 17.8% of the sample met criteria for a current ED, with 6.7% meeting criteria for Anorexia Nervosa (AN), 5.9% for Bulimia Nervosa (BN), and 5.2% for Binge-Eating Disorder (BED). In this BPD sample, in the last year, current BN was associated with a significantly greater risk of recurrent suicide attempts while current AN was associated with increased risk of recurrent non-suicidal self-injury. BPD with current AN or BED was associated with a greater number of non-ED current Axis I disorders. Further replication of these results is needed. Women with BPD must be assessed for AN and BN as these diagnoses may confer greater risk for suicidal and self-injurious behavior and may have to be prioritized in treatment.
