In the present study, an attempt has been made to elucidate sex differ
ences present in the Axis II, personality disorders, in the DSM-III-R.
Five-hundred and thirty-one subjects, 176 healthy volunteers and 355
psychiatric patients, 231 males and 300 females, were investigated by
means of the SCID screen questionnaire. There were significant sex dif
ferences as concerns 31 out of total 103 Axis II criteria. The most pr
onounced sex differences were seen in narcissistic, borderline and ant
isocial personality disorders. As a previous study demonstrated that p
ersonality disorders are in fact dimensional traits where the cut off
points are placed within a normal rather than a bimodal distribution,
it was of interest to elucidate the number of criteria fulfilled for e
ach separate personality disorder. Significant sex differences in this
dimensional perspective were seen in self-defeating and borderline pe
rsonality disorders (females predominating). Antisocial personality tr
aits were more common among males.It has also been demonstrated in an
earlier study that if an adjusted cut-off is used, the presence or abs
ence of personality disorders can be determined by means of the SCID s
creen questionnaire with an accuracy of a kappa coefficient = 0.78. If
such a method is used, males had a higher prevalence of obsessive-com
pulsive and schizoid personality disorder. The opposite was true for b
orderline personality disorder.
