Construction of the Big Five Scales of personality trait terms and concurrent validity with NPI

Abstract

The purpose of this paper is to construct the Big Five Scales (BFS) of personality trait terms which are based on the items of ACL (Adjective Check List). First, the five-factor solution corresponding to the Big Five was obtained after a few steps of analysis, and then BFS was constructed. Next, the concurrent validity of BFS was investigated by means of joint factor analysis with a new type of personality inventory (NPI), at item level as well as scale level. It follows from these results that BFS is good markers for personality factors and NPI measures a wide area of personality traits which covers the Big Five.
