Psychologists in clinical and forensic settings are sometimes asked to assess the personality of a man, who commited crime with sexual features. One of the method, which is usually used for the assessment of personality, is the Rorschach inkblot test. To study the diagnostic possibilities of the Rorschach test in the area of paraphilias we have collected 78 protocols of men who commited a sexual crime and who have been diagnosed with paraphilia. We have found in our research sample statistically significant difference in several Rorschach variables, which firstlly reffer to self- perception and interpersonal perception. We have also compared our research groups with Exners norms of nonpatients and character disoders.
