title: Gender bias in diagnostic criteria for personality disorders: an item response theory analysis.
abstract: The authors examined gender bias in the diagnostic criteria for Diagnostic and Statistical Manual of Mental Disorders (4th ed., text revision; American Psychiatric Association, 2000) personality disorders. Participants (N=599) were selected from 2 large, nonclinical samples on the basis of information from self-report questionnaires and peer nominations that suggested the presence of personality pathology. All were interviewed with the Structured Interview for DSM-IV Personality (B. Pfohl, N. Blum, & M. Zimmerman, 1997). Using item response theory methods, the authors compared data from 315 men and 284 women, searching for evidence of differential item functioning in the diagnostic features of 10 personality disorder categories. Results indicated significant but moderate measurement bias pertaining to gender for 6 specific criteria. In other words, men and women with equivalent levels of pathology endorsed the items at different rates. For 1 paranoid personality disorder criterion and 3 antisocial criteria, men were more likely to endorse the biased items. For 2 schizoid personality disorder criteria, women were more likely to endorse the biased items.
