The purpose of this study was to identify psychological characteristics of schizophrenic patients whose scores on scale 8(Sc) and BIZ(Bizarre Mentation) scale were less than T-score 70. Also, the relationship between chronicity of schizophrenia and reported bizarreness on the MMPI. Subjects were 48 patients who were diagnosed as schizophrenia by a clinical psychologist and psychiatrists based on the cirteria of DSM-IV(APA, 1994). There was no significant relationship between chronicity of schizophrenia and reported bizarreness on the MMPI. When compared with schizophrenic patients showing scores at or above T-score 70 on scale 8 and/or BIZ scale, the patients with non-bizarreness on the MMPI showed better performance in Vocabulary subtest of KWIS and normal profile tendency on the MMPI, but exposed perceptual inaccuracy in the Rorschach test. The results suggest that non-bizarze schizophrenic patients had better verbal ability remained, which made them be able to show less mental disturbances in verbally structured tests such as MMPI and KWIS. However, the non-bizarre group did not show the obvious signs of thought disorder but the signs of failure of perceptual integration and inaccuracy on the Rorschach test which is less structured. The results were discussed integratively, and suggestions for a future study were proposed.
