Abstract
Objective:The purpose of this study was to investigate the relationship between intellectual decline and severity of psychopathology in the participants of adult schizophrenia.

Purpose:At first, K-WAIS was conducted in 67 participants. The participants were divided into two groups according to the differences between full scale IQ and estimated premorbid IQ. MMPI and SCL-90-R were compared to these two groups.

Results:In a group of severely impaired group(SIG), the scores of somatization, obsession-compulsion, interpersonal sensitivity, depression, hostility, phobic anxiety, paranoid ideation, and psychoticism subscales in SCL-90-R were significantly higher than mildly impaired intelligence group(MIG). In the scores of MMPI, F, masculinityfemininity, paranoia, psychasthenia, schizophrenia, and hypomania subscales were significantly higher in SIG than those of MIG.

Conclusions:Psychopathology of the patients with SIG was more severe than the participants with MIG and the distress level of the patients with SIG was also much higher than the participants with MIG.
