title: Stability and factor structure of the Jackson Personality Inventory--Revised.
abstract: The Jackson Personality Inventory--Revised comprises 15 bipolar scales and five cluster scores concerning an individual's interpersonal patterns of interaction, cognitive styles, and value orientation. Recent reviews of this revised version raise questions about test-retest stability as well as the factor structure on which cluster scores are based. 74 men and 33 women (29-63 years of age, M = 42.3) completed the inventory while participating in a continuing education program. Of these 45 participated in a second session 13 wk. later. Test-retest correlations are significant, with 12 of the 15 scales having correlations > or = .75. Intercorrelations among all subscales indicate that the Jackson subscales for the most part remain distinct from each other ranging from .01 to .59. A Principal Components Analysis with a varimax rotation yielded three factors that parallel the NEO big five, i.e., Openness, Neuroticism, and Extroversion and replicated previous factor structure found for both versions of the Jackson inventory. The fourth and fifth factors here were labeled Trustworthy and Organization; however, the composition of these factors across several studies appears to be unstable, suggesting optimal certainty when interpreting the clusters of subscales associated only with Openness, Neuroticism, and Extroversion. Further research may help clarify the instability associated with the other factors of this inventory.
