This study was designed to investigate the intelligence impairment in patients with schizophrenia and K-WAIS scatter analysis by subtype and prevalence period. 57 patients with schizophrenia divided into four groups(acute-paranoid(N=11), acute-nonparanoid(N=9), chronic-paranoid(N=21), chronic-nonparanoid(N=16)) by subtype and prevalence period. The results showed that estimated premorbid IQ from demographic variables were no significant differences among four groups, and all groups had average intelligence. Chronic-nonparanoid group was significantly decreased current IQ. In all groups, performance IQ lower than verbal IQ, but there was not significant difference. Chronic-nonparanoid group showed the most severe scatter and the lowest cognitive efficiency in K-WAIS scatter analysis.
