Factor Analysis of the Personal Profile System.
Peer reviewed Peer reviewed
Henkel, Thomas George; Wilmoth, James Noel – Journal of Experimental Education, 1992
Principal components extraction with orthogonal and oblique rotations tested the construct validity of the Personal Profile System (PPS) using data from 1,045 senior noncommissioned Air Force officers. Four factors accounted for 85 percent of the total variance, but the results do not completely justify publisher claims for the PPS. (SLD)
