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.
