DIMENSIONS OF PERSONALITY: II. SEPARATE FACTOR STRUCTURES IN GUILFORD AND CATTELL TRAIT MARKERS

Area of Science:

• Psychology
• Psychometrics

Background:

• This research builds upon prior work detailed in Sells, Demaree, and Will (1970).
• It addresses the need for robust validation of psychological constructs through empirical analysis.

Purpose of the Study:

• To conduct independent factor analyses and rotations of a large item set.
• To examine the marker items for Guilford source factors and Cattell source factors.

Main Methods:

• Factor analysis was performed on 300 Guilford items and 300 additional items.
• Rotational techniques were applied to interpret the extracted factors.
• Items served as markers for 15 Guilford source factors and 17 Cattell source factors.

Main Results:

• The analysis yielded distinct factor structures for the Guilford and Cattell item sets.
• The marker items provided evidence for the proposed source factors.

Conclusions:

• The study contributes to the understanding of personality structure through factor analytic methods.
• Findings support the utility of the Guilford and Cattell factor models in psychological research.
