The Relation between Wisconsin Card Sorting Test and Psychotic Symptoms in Schizophrenia

The purpose of this study was to investigate 1) the difference of performance on the Wisconsin Card Sorting Test(WCST) between schizophrenecs and normal controls, 2) and the change of performance while clinically improved. WCSTs were administered in 28 schizophrenics and 32 normal controls. The results were as follows. 1) Schizophrenic patients performed poorly on the WCST compared to normal controls. 2) There was no significant change of performance in WCST as clinical symptoms improved 3) There was no significant correlation between the performance of the Wisconsin Card Sorting Test and age, sex，education level and volcabulary test in both groups. These findings suggest that the WCST may be an indicator of vulnerability to schizophrenia
