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.
本研究旨在调查精神分裂症患者创造力的特定测量指标及其与神经认知执行功能的关系。研究纳入了43例处于症状缓解期的偏执型精神分裂症住院患者（共60例）和45名健康对照参与者。使用巴伦-威尔士艺术量表（BWAS）和柏林智力结构测试（BIS）的创造性部分评估创造力。通过威斯康星卡片分类测试（WCST）测量执行功能。与对照受试者相比，精神分裂症患者在BWAS上的得分较低，在BIS的总分和图形测试中得分较低，并且在WCST的所有领域表现更差。他们在BIS上的较低得分与WCST上的较低得分相关。我们的结果表明，缓解期精神分裂症患者在特定创造力测量指标上的表现比健康受试者差，并且执行功能障碍可能部分解释了这些缺陷。
