Creative thinking deficits in patients with schizophrenia: neurocognitive correlates.

Author information

Department of Adult Psychiatry, Poznań University of Medical Sciences, Poznań, Poland.


The aim of this study was to investigate selected measures of creativity in schizophrenic patients and their relationship with neurocognitive executive functions Forty-three inpatients with paranoid schizophrenia who were in symptomatic remission (a total of 60) and 45 healthy control participants were included. Creativity was assessed using the Barron-Welsh Art Scale (BWAS) and the inventiveness part of the Berlin Intelligence Structure Test (BIS). Executive functions were measured by means of the Wisconsin Card Sorting Test (WCST). Schizophrenic patients gave responses on the BWAS, had lower total score on the BIS and in the figural test, and performed worse on all domains of the WCST compared with control subjects. Their lower scores on the BIS correlated with lower scores on the WCST. Our results indicate that remitted schizophrenic patients perform worse on selected measures of creativity than healthy subjects and that executive dysfunctions may partially explain these deficits.
