title: [Letter fluency: psychometric properties and Dutch normative data].
abstract: Normative data were collected for a Dutch version of the Controlled Oral Word Association Test (COWAT) in 200 healthy subjects between 17 and 89 years of age. The COWAT is a letterfluency task that is widely used in clinical neuropsychology. Fluency is an important aspect of executive functioning. The psychometric properties of the Dutch version of the test were largely comparable to those of the original COWAT. Its reliability is 0.80, and its scores are significantly related to level of education and/or vocabulary, but not to age or gender. A regression formula is provided by which the raw scores can be corrected for level of education.
