89 male and 68 female patients following their request for gender change

The patients were divided in three groups according to their main diagnosis: 38 patients were diagnosed with histrionic personality disorder, 52 patients with transsexualism and 67 patients with schizophrenic disorders. The unspecific attributes of the first group were correspondence between gender identity and gender preferences and biological gender (92%) and absence of the negative image of the opposite gender (93%). In the second group patients didn't identify themselves with infantile male and female images (87%), gender preferences did not fit the image of own biological gender (90%) and there was no distortion in representation of male and female roles on both logical and emotional levels elicited (87%). Images of ideal and real sexual partners did not correspond with the image of gender wanted (90%) and emotionally ambivalent or negative one's image appraisal was absent (83%). It was not possible to determine non-specific characteristics in the third group as their combination was too diverse.

evaluation of non-specific psychological attributes for each separate diagnostic group can be a valuable tool in differential diagnostics of gender identity disorders.
