Abstract
The Big Five Inventory (BFI-44) has been a useful tool for researchers for over three decades. However, the contemporary way of life has created the need for abbreviated versions of psychological instruments. We derived the number of items from the BFI-44 questionnaire in order to create a short form of the questionnaire (BFI-20). In the first study ( N = 1350, 82.4% females, aged 18–60), using a range of criteria, we identified 20 items (four for each of the Big Five traits) that most optimally represent each dimension. The five-factor structure was mostly replicated in the second ( N = 215, 65.1% females, aged 18–65) and third study ( N = 263, 83.7% females, aged 18–42). The BFI-20 demonstrated satisfactory reliability, representativeness, homogeneity, and part-whole convergence. Despite mild attenuation, most BFI-20 correlations with schizotypy, satisfaction with life, and positive orientation remained in the same range compared to the BFI-44. The Agreeableness domain was shown to be the most challenging for capturing with four items. We discuss the advantages of our BFI-20 compared to the other two 20-item versions. In sum, we can recommend the use of this BFI-20 version as a time-efficient, satisfactory reliable, and representative questionnaire.
