Higher Order Factor Convergence and Divergence of Two Distinct Personality Systems: Cattell's HSPQ And Jackson's PRF

The 14 scales of the HSPQ and 20 scales of the PRF were administered to 1,862 adolescents. Scales were intercorrelated, factored, and the factors rotated to simple structure solutions, separately for each instrument. Cross-instrument relationships were subsequently examined by: (a) Dwyer extension analysis procedure, and (b) estimating correlations of "true" factor scores between the two sets of factors. Results indicated both cross-instrument commonalities and specificities. Higher stratum dimensions (HSPQ-PRF) of Exvia-Ascendance, Superego Strength-Impulse Control, Cortertia-Aesthetic Intellectual Orientation, and Dependence-Social Contact were found to be closely related in the two instruments. Dimensions such as Aggression (PRF), Achievement (PRF), and Anxiety (HSPQ) were found to be instrument-specific. It was concluded that neither instrument provides for a comprehensive mapping of the personality domain, broadly defined. Implications of the levels of factor convergence and divergence obtained in relation to theory building and prediction are discussed.
