Factor analysis of the Stewart Personality Inventory Research Form and its correlations with some other personality instruments

The 80-item Stewart Personality Inventory (SPI) has 8 sub-scales; Orderliness, Future orientation, Extraversion, Self-concept, Autonomy, Risk-taking, Nurturance and Scientific-practicality. The inventory and scoring methods are summarised. A factor analysis yielded a very similar factor structure to that of an earlier study, despite different factor methods and cultural settings for the studies. Presented also are correlations of the SPI subscales with the Bell Home Adjustment Scale, California Psychological Inventory, Eysenck Personality Inventory, Machievellianism Scale, Wrightsman Philosophies of Human Nature Scale, Rubin and Peplau "Just World" scale and the Wilson-Patterson Conservatism Scale. The results are generally supportive of the Inventory's validity.
