言语流畅性测试被广泛用于执行功能的评估。然而，传统版本的测试取决于这些组件之外的几个认知因素。本研究的目的是评估协会的口头流畅性的修改版本与具体措施的执行功能。60名成年人使用传统版本的语言流畅性（动物/水果）和修改后的条件下，受试者必须在动物和水果之间切换进行评估。还评估了处理速度、语义能力、精神症状和执行功能。语言流畅性测试和执行功能的措施，控制人口，认知和精神症状之间的偏相关性，表明认知灵活性有9%的共享方差与语言流畅性测试-类动物，2%与类水果，8%与总的话在切换条件下，和20%与总的正确的词对在切换条件下产生的。执行功能的其他方面在任务期间与语言流畅性任务的差异在1%到7%之间。结果表明，正确的词对转换言语流畅性可能是一个更具体的措施相比，其他版本的言语流畅性评估的认知灵活性。
Verbal fluency tests are widely used for the assessment of executive functions. However, traditional versions of the test depend on several cognitive factors beyond these components. The aim of this study was to evaluate the associations of a modified version of the verbal fluency with specific measures of executive functions. Sixty adults were evaluated using traditional versions of verbal fluency (animals/fruits) and a modified condition where subjects must switch between animals and fruits. Processing speed, semantic abilities, psychiatric symptoms and executive functions were also assessed. Partial correlations between the verbal fluency tests and measures of executive functions, controlled for demographic, cognitive and psychiatric symptoms, suggest that cognitive flexibility has 9% shared variance with the verbal fluency test – category animals, 2 % with category fruits, 8% with total words in switching condition, and 20% with total correct word-pairs produced in switching condition. The other aspects of executive functions during the task had shared variance of between 1% and 7% with the verbal fluency tasks. The results suggest that correct word-pairs produced in switching verbal fluency may be a more specific measure for evaluating cognitive flexibility compared to other versions of verbal fluency.
