[Factor analysis on the intelligence of patients with schizophrenia].
The authors made a factor analysis on the intelligence of patients with schizophrenia. 119 patients with schizophrenia were measured by Wechsler Adult Intelligence Scale-Revised China (WAIS-RC). The results revealed the average full intelligence quotient (IQ) of schizophrenia was 79.70, the verbal intelligence quotient(VIQ) 84.43, and the performance intelligence quotient(PIQ) 74.10. Multiple regression showed the regression coefficient of educational level for IQ was 8.6721. The regression coefficient of the course of disease for IQ was negative 0.1519. Factor analysis showed that the cumulative percent of three-factor solution of schizophrenia was 73.5. In conclusion, the IQ of most patients with schizophrenia was lower than norm, VIQ > PIQ(P = 0.0000). Educational level had greater influence on IQ. The longer the course of disease was, the worse the intelligence came to be. Factor analysis indicated that three-factor solution of schizophrenia was similar to that of norm, but each subtest value was lower than norm.
