The 10-Item Big Five Inventory - Norm values and investigation of sociodemographic effects based on a German population representative sample

The 10-Item Big Five Inventory (BFI-10; Rammstedt & John, 2007), a short scale version of the well-established BFI, was developed to provide a personality inventory for research settings with extreme time constraints. It allows assessing the Big Five by only two items per dimension. Previous research has clearly shown that the BFI-10 possesses psychometric properties that are comparable in size and structure to those of the full-scale BFI. Based on data from a large sample representative of the German adult population, the present study aimed to provide norms for the total sample and for subsamples depending on different sociodemographic variables and to investigate effects of gender, age, and education on the BFI-10. Results indicate that the sociodemographic effects found in the German representative sample clearly replicate those of previous research conducted in that field.
