Abstract
The genuine prevalence of personality disorders among those with eating disorders is unknown. However, in this paper, we summarize the existing data, with careful acknowledgment of our approach to interpretation as well as the limitations of previous studies. Our findings indicate that obsessive-compulsive personality is the most common personality disorder in restricting-type anorexia nervosa, while borderline personality is the most common personality disorder in binge-eating/purging type anorexia nervosa. Borderline personality is the most common personality disorder in bulimia nervosa, as well. In those with binge eating disorder, obsessive-compulsive personality is the most common personality disorder although, compared with the preceding eating disorder diagnoses, there are broader clusters of personality disorders represented in this group. We discuss the implications of these findings.
