 ====== Ruff Figural Fluency Test ======
-The RFFT is a measure of nonverbal fluency, a parameter of executive cognitive functioning. The RFFT consists of five parts, each presenting a different stimulus pattern of dots, in which the task is to draw as many unique designs as possible within a set time period.
+The Ruff Figural Fluency Test (RFFT) ([[sections|section]]: [[mental health]]) was measured in all [[start|Lifelines]] participants aged 18 years and older during:
+  * [[1A Visit 1]] (n = ~91.000)
+  * [[3A Visit 1]]
-The RFFT was measured on paper in approximately 50% of adult and elderly participants that underwent [[1A Visit 1]], as the RFFT and [[Pulmonary function test|Spirometry]] were measured in alternate weeks.\\
+===== Background =====
-The RFFT will be measured digitally during [[3A Visit 1]]

+The RFFT was measured on paper in adult and elderly [[start|Lifelines]] participants during [[1A Visit 1]]. Participants underwent either the RFFT or [[Pulmonary function test|Spirometry]], as these tests were performed in alternate weeks.\\
+In assessment [[2A Visit 1|2A]], executive cognitive functioning was measured with [[CogState]] instead of the RFFT.\\
+In assessment [[3A Visit 1|3A]], both the RFFT and CogState are measured with tablet and PC.

 Results of the study show that the mean number of unique designs increased significantly from 73 (+/-26) at baseline to 79 (+/- 27) at first follow-up, and 83 (+/- 26) at second follow-up overall (p < 0.001).

 The RFFT may be analyzed by humans or by computer software, yielding similar results ((Elderson, M.F., Pham, S., Eersel, M.E.A. van, Study, L.C., Wolffenbuttel, B.H.R., Kok, J., Gansevoort, R.T., Tucha, O., Klauw, M.M. van der, Slaets, J.P.J., et al.
