title: Specific and nonspecific comorbidity in anorexia nervosa.
abstract: OBJECTIVE
  This article reports lifetime Axis I and II comorbidity in women with anorexia nervosa (AN), and ascertains specific and nonspecific comorbidity in AN compared to clinical samples of women with bulimia nervosa (BN) or major depression (DEP).
  
  
  METHODS
  Outpatient AN (n = 56), BN (n = 132), and DEP (n = 100) samples were assessed using Structured Clinical Interviews I and II for DSM-III-R. Baseline data were compared using univariate statistics and logistic regression.
  
  
  RESULTS
  In the AN sample as a whole, specific elevations were found for prevalences of obsessive compulsive disorder. The AN-binge eating purging subtype (AN-BP) and the BN sample had elevated prevalences of Cluster B personality disorders. Cluster C prevalences were elevated across samples.
  
  
  CONCLUSIONS
  Evidence of AN-specific, eating disorder-specific, and nonspecific comorbidity illustrates the heterogeneity in AN. Further research is need to examine the relative impact of specific and nonspecific comorbidity in AN subtypes and AN as a whole.
