| Description | Objectives. The aim of the study was estimation of basic psychometric properties of the Czech adaptation of the Big Five Inventory 2 (BFI-2) measuring five basic personality dimensions and their short and extra short versions (BFI-2-S, BFI-2XS). Subject and settings. The BFI-2 was administered to 1,733 participants (42.1% men, 57.9% women) in age range from 15 to 26 years (M = 20.06, SD = 2.53). Hypothesis. Authors expected that the Czech adaptation of the BFI-2, BFI-2-S, BFI-2XS will retain comparable psychometric properties to the original versions. Statistical analysis. Internal consistency of BFI- 2, BFI-2-S, BFI-2XS domains and BFI-2, BFI- 2-S facets was estimated using Cronbach’s alpha coefficient and ordinal McDonald’s omega coefficient. Test-retest stability of the three methods was estimated using Pearson’s correlation coefficient. The structure of the BFI-2 at the level of items was explored using Principal Component Analysis with Varimax rotation; structures of domains were confirmed using Confirmatory Factor Analyses. The ability of the BFI-2-S and BFI-2-XS scales to represent BFI-2 scores was assessed using the Pearson correlation coefficient. Results. The BFI-2 domains showed good internal consistency, ranging from 0.81 to 0.89. Internal consistency of individual facets ranged from 0.56 to 0.83 (M = 0.74). Average BFI-2 test-retest reliability estimated over a 6 month period was r = 0.86 for domains and r = 0.80 for facets. All items of the BFI-2 showed factor loadings 0.30 or higher on intended factor. The BFI-2 hierarchical structure with 15 facets was confirmed using CFA. Short versions BFI-2-S and BFI-2-XS captured 91% and 77% of the domains of the full version of BFI-2 inventory. Study limitation. Convergent validity of the instrument and the self-other agreement was not evaluated. |
