Objective:
The purpose of this study was to test whether poor insight in patients with psychotic disorders is correlated with their performance on the Wisconsin Card Sorting Test.
Method:
The subjects included 52 psychotic patients (35 of whom had schizophrenia) given diagnoses according to DSM-III-R criteria. Their scores on the Wisconsin Card Sorting Test (number of categories and perseverative responses) were compared 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 neuropsychological test and the three items measuring insight was significant.
Conclusions:
In spite of its limitations, this study suggests that poor insight may not be associated with poor performance on the Wisconsin Card Sorting Test.
