Personality for free: Psychometric properties of a public domain Australian measure of the five-factor model

Abstract

Fifty items from Goldberg's International Personality Item Pool were compiled to form a public-domain measure of personality, the Australian Personality Inventory (API). Data from a random community sample (N=7615) and a university-based sample (N =271) were used to explore psychometric properties of this 50-item measure of the five-factor model of personality (FFM). In both samples, internal reliabilities were adequate. In the university-based sample an appropriate pattern of convergent and divergent relationship was found between scale scores and domain scores from the NEO Five-Factor Inventory. After adjusting for an apparent response set (mean response across items), exploratory factor a..
