Although many professionals have speculated that sex may be related to personality disorders, there is little research that has examined how gender roles may affect personality disorders. This study focused on whether gender role phenomena would be related to personality disorders. The results indicated that (a) expressiveness (i.e., psychological femininity) correlated negatively with 10 of the DSM - IV measures of personality disorder and (b) that instrumentality correlated negatively with borderline, avoidant, dependent, negativistic, and depressive personality disorder. Several aspects of the masculine role were also systematically related to paranoid, schizoid, narcissistic, avoidant, and dependent personality disorder. The discussion focuses on the implications and limitations of the present findings.
