INTERNAL CONSISTENCY OF CZECH VERSION OF NEO-FFI INVENTORY

The psychometric properties of the translated NEO Five-Factor Inventor y (NEO-FFI) designed to measure the five personality dimensions were e xamined in a sample of 945 Czech subjects. The NEO-FFI comprises 12 it ems for each of the five personality domains Neuroticism, Extraversion , Openness, Agreeableness, and Conscientiousness. The internal consist encies of the five scales ranged from 0.60 to 0.84. Factor analysis of the NEO-FFI items supported the scoring key of the inventory, althoug h some items supposedly measuring the factors Openness to experience a nd Agreeableness should be improved by revision. The authors discuss t he psychometric characteristics of the NEO-FFI in Non-American sample and findings concerning the generalizibility of the instrument across German, Canadian, and Polish samples. The results demonstrate psychome tric adequacy of the NEO-FFI in Czech language.
