[Investigation of the concurrent validity of a new personality inventory: construction of a new personality inventory by means of factor analysis based on promax rotation (II)].
The purpose of the present study is to investigate the concurrent validity of a new type of personality inventory (NPI) which has been constructed by the present authors. For this purpose, we conducted three kinds of studies. The first one was to find the relationship of the 13 scales of the NPI with the 12 scales of YG personality inventory. Factor analysis and canonical correlation analysis were employed for the study. It was found that the NPI measured relatively wider area of personality traits as compared with the YG inventory. The second and the third studies were concerned with the concurrent validity of the NPI. The inventory was applied to both six hundred company workers and two hundred university students, and they were classified into adjusted and maladjusted groups respectively according to their responses to a questionnaire aimed at measuring the adaptability to jobs or to majors. Results showed that the 13 scales of the NPI had a strong predictive power in the sense of the concurrent validity. Further studies are needed in order to measure the predictive validity of all the scales of the present personality inventory.
