 ====== 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 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. (2016). Agreement between Computerized and Human Assessment of Performance on the Ruff Figural Fluency Test. PLOS ONE 11, e0163286)).
-Lifelines uses both RFFT and [[CogState]] to assess executive cognitive functions. In how far do these two instruments measure the same thing? A total of 509 participants (mean age (SD): 53 years (14.6); range 18–87 years) participated in this study. All correlations between the RFFT and the CogState were statistically significant (except for the correlation between the RFFT error ratio and the CogState One Back Task), ranging from -0.39 to 0.28. Stratifying the analyses for age, education, and gender did not substantially affect our conclusions. Sensitivity analyses showed no substantial influence of level of computer experience or (physical) impairments ((Kuiper, J.S., Oude Voshaar, R.C., Verhoeven, F.E.A., Zuidema, S.U., and Smidt, N. (2017). Comparison of cognitive functioning as measured by the Ruff Figural Fluency Test and the CogState computerized battery within the LifeLines Cohort Study. BMC Psychol. 5, 15)).
