Intelligence and Related Factors in Schizophrenia
Abstract：Objective To explore the relationship of intelligence among memory, sustained attention and executive function of schizo-phrenic patients. Methods 120 schizophrenic inpatients and 60 healthy subjects matched in age, gender and years of education with the pa-tients were assessed with Wechsler Adult Intelligence Scale-fourth edition (WAIS-IV) and Wechsler Memory Scale-fourth edition (WMS-IV), Continuous Performance Test (CPT), Wisconsin Card Sorting Test (WCST). Results The intelligence quotient (IQ), memory quotient (MQ), scores of CPT and WCST were poor in the patients (P<0.05). IQ was correlated with MQ (r=0.837, P<0.01), the scores of CPT (r=0.613, P<0.01) and WCST (r=0.466, P<0.01). The scores of CPT and MQ were the independent factors related with IQ (P<0.001). Conclusion There is intelligence impairment in schizophrenics, which may related with the impairment of memory and sustained attention.
