THE JACKSON PERSONALITY-INVENTORY AND THE 5-FACTOR MODEL OF PERSONALITY

This article describes the results of several analyses of structure un derlying the personality variables of the Jackson Personality Inventor y (JPI; Jackson, 1976, 1994). Ten different data sets showed that, whe n three of the JPI scales were removed from the analyses, a very clear five-factor structure emerged. The five factors more or less resemble d the well-known Big Five dimensions of personality. Somewhat at varia nce with the Big Five structure, however, was the tendency of our Cons cientiousness factor to split into dependability and organization comp onents. Furthermore, not all JPI variables found a place in the Big Fi ve factor space. Risk Taking, Energy Level, and Value Orthodoxy were s ufficiently independent of the obtained factors to suggest that those variables might define separate factors in their own domains.
