RFFT reference sample Groningen the Netherlands

IBM SPSS Statistics version 22 file including the individual data on performance on the Ruff Figural Fluency Test (RFFT) of 4,135 participants of the third survey of the Prevention of Renal and Vascular ENd-stage Disease (PREVEND) study, city of Groningen, the Netherlands (2003-2006). The file includes the data of all participants who agreed to perform the RFFT and the data of the Groningen Random Sample (GRS). The GRS was created because, due to its design, the total PREVEND cohort comprised a relatively high number of persons with microalbuminuria which is possibly negatively associated with cognitive function. The prevalence of microalbuminuria in the GRS was similar to the prevalence in the general population.
