Abstract

The big five personality traits are the best acknowledged and most commonly used the model in psychology. Therefore, many personality scales are developed based on this personality model. IPIP-BFM-50 is one of the open-source scales measuring big five personalities that is widely used by world researchers. This study aimed to adapt IPIP-BFM-50 into Indonesian and evaluate its psychometric properties. The adaptation was done by following the guidelines of the International Test Commission (ITC). The result shows that IPIP-BFM-50 Indonesia has Aiken's V index ranging from 0.71 - 0.98. Alpha reliability with n = 502 ranges from 0.762 (agreeableness) to 0.862 (emotional stability). Factor analysis shows that the items are well-grouped according to their dimensions with loading factor ranging from 0.34 to 0.75 on the factors measured. Thus, IPIP-BFM-50 Indonesia has satisfactory psychometric properties and can be used to measure the Big five personality.

Abstract

Koefisien korelasi aitem-total ini sering disalahartikan sebagai koefisien validitas aitem, padahal validitas aitem memiliki pengertian yang sama sekali berbeda. Koefisien korelasi aitem-total tidak memberikan informasi mengenai validitas aitem tetapi memberikan informasi mengenai konsistensi antara apa yang diukur oleh aitem dengan apa yang diukur oleh tes.
