Objectives. The aim of the study was estimation of basic psychometric properties of the Czech adaptation of the International Personality Item pool - Big Five Markers - 50 (IPIP-BFM-50) measuring five basic personality dimensions and its short version the Mini IPIP-BFM-20. Subject and settings. The sample consisted of 715 participants (318 males and 397 females) ranging in age from 15 to 26 years (M=18.74, SD=2.77). Hypothesis. Authors expected expected that the Czech adaptation of the IPIP-BFM-50 and the Mini IPIP-BFM-20 will retain comparable psychometric properties to the original versions. Statistical analysis.The internal structure was estimated using confirmatory factor analysis (CFA). Authors estimated composite reliability, test-retest stability was estimated using the Pearson correlation coefficient. Convergent and discriminant validity was assesed by average variance extracted (AVE) and maximum shared variance (MSV). The ability of the Mini IPIP-BFM-20 scales to represent IPIP-BFM-50 scales was assessed using the Pearson correlation coefficient. Results showed an acceptable fit with the original structure on the item level in both versions. Composite reliability ranged from 0.86 to 0.90 (M = 0.87), test-retest reliability from 0.78 to 0.87 (M = 0.82). Correlations with Big Five Inventory-2 ranged from 0.73 (Intellect/Imagination) to -0.88 (Emotional Stability). Reliability of the Mini IPIP-BFM-20 was better than in the original study, retest reliability was excellent for four dimensions, good for one dimension, validity was good or excellent, measurement equivalence for women and men was established and the same gender differences as in alternative Big Five measures were observed. The Mini-IPIP-BFM-20 shared 86% of the variance with the full IPIP version. The results indicate that both metods are psychometrically acceptable and practically useful measures of the Big Five factors of personality. Study limitation. The self-other agreement was not evaluated, and age norms were not established.
