IS POOR INSIGHT IN PSYCHOTIC DISORDERS ASSOCIATED WITH POOR PERFORMANCE ON THE WISCONSIN CARD SORTING TEST

Objective: The purpose of this study was to test whether poor insight in patients with psychotic disorders is correlated with their performa nce on the Wisconsin Card Sorting Test. Method: The subjects included 52 psychotic patients (35 of whom had schizophrenia) given diagnoses a ccording to DSM-III-R criteria. Their scores on the Wisconsin Card Sor ting Test (number of categories and perseverative responses) were comp ared with those on three items measuring poor insight: lack of feeling ill, lack of insight, and uncooperativeness. Results: None of the six correlations between scores on the two measures of the neuropsycholog ical test and the three items measuring insight was significant. Concl usions: In spite of its limitations, this study suggests that poor ins ight may not be associated with poor performance on the Wisconsin Card Sorting Test.
