Summary
Eating disorder not otherwise specified (EDNOS) is prevalent in female borderline patients, manifesting in distinct subtypes. These findings suggest EDNOS is a separate disorder cluster in this population.
Area of Science:
- Psychiatry
- Clinical Psychology
- Eating Disorders
Background:
- Borderline personality disorder (BPD) is frequently comorbid with eating disorders.
- Eating Disorder Not Otherwise Specified (EDNOS) is a common diagnosis in clinical settings.
- Understanding the specific presentation of EDNOS in BPD is crucial for effective treatment.
Purpose of the Study:
- To determine the prevalence of EDNOS and its subtypes in female patients with BPD.
- To differentiate EDNOS in BPD from anorexia nervosa and bulimia nervosa.
Main Methods:
- A sample of 233 female borderline patients and 46 female Axis II comparison subjects were assessed.
- The Structured Clinical Interview for DSM-III-R Axis I disorders was utilized.
- Lifetime prevalence of EDNOS and its subtypes was evaluated.
Main Results:
- 33% of female borderline patients met DSM-III-R criteria for EDNOS.
- Common EDNOS subtypes included binging without purging (37%) and purging without binging (37%).
- Less than 25% of these patients had criteria for anorexia nervosa or bulimia nervosa.
Conclusions:
- EDNOS appears as a distinct cluster of eating disorders among women with BPD.
- EDNOS in this population is not merely a prodromal or residual phase of anorexia or bulimia nervosa.
- These findings support the classification of EDNOS as a separate diagnostic entity in BPD.
