Abstract
By using the Adjective Check List (ACL) in its Japanese version, the concurrent validity of a personality inventory is investigated through canonical correlation analysis and procrustes factor rotation from the view of the Five Factor Model concerning personality traits. After describing the objective of the present paper, the principles both of canonical correlation analysis and of incomplete orthogonal procrustes factor rotation to be used are explained. And, following the description concerning samples and data for analysis, the results both based on the scales and on the items of the personality inventory are presented. The important role of procrustes type of factor rotation in editing personality inventory is stressed before closing the discussion.
