Validation of Big Five Inventory-2 (BFI-2) for Indonesia: Not perfect but still valid and reliabel to measure personality

The Big Five Inventory-2 (BFI-2) is the latest version of the personality measurement tool according to the theoretical framework of the five-factor model. This study aims to replicate the validity of the BFI-2 test in the Indonesian version. The validity test related to internal structures were conducted using Principal Component Analysis (PCA) and Confirmatory Factor Analysis (CFA), while convergent validity was generated through correlation with BFI-1. The respondents was 853 students from several state and private universities in North Sumatra and East Java. Online data collection was conducted using Google Form. The results of the PCA showed that 50 items (83%) of the Indonesian version of BFI-2 have an adequate loading factor to the related dimensions. The results of the CFA on the facet level model have a better fit index than the dimension level, meaning that these findings support the facet level measurement model of BFI-2 Indonesia. The five dimensions of Indonesia’s BFI-2 have positive correlations with the BFI-1 dimension at a moderate level. Thus, it showed that Indonesia's BFI-2 is proven to be converging with BFI-1
