精神分裂症患者的智力及其因子分析

为探索精神分裂症患者的智力及其效度,采用韦氏成人智力量表中国版(WAIS-RC)对119例精神分裂症患者进行了测验.结果:精神分裂症患者的智商均值为79.70,言语智商为84.43,操作智商为74.10.文化程度对智商的回归系数为8.6721.病程对智商的回归系数为-0.1519.因子分析显示,精神分裂症患者的三因子模型的累计贡献率为73.5%.上述结果表明,多数精神分裂症患者的智商低于正常人,其言语智商大于操作智商,病程越长,智商越低.文化程度对智商的影响较大.精神分裂症患者的三因子模型与常模的三因子模型相似,但各分测验值普遍偏低.

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.
