Theoretical Considerations For Extracting Meaning From Personal Profile System Data: The Need For Independent Construct Validity Studies, Thomas G. Henkel, James Noel Wilmoth
Theoretical Considerations For Extracting Meaning From Personal Profile System Data: The Need For Independent Construct Validity Studies, Thomas G. Henkel, James Noel Wilmoth

The Personal Profile System (PPS) is a psychological testing instrument that has been widely used. The construct validity of the PPS was studied through a review of the literature. This paper organizes the literature review into three broad categories: the background of the PPS; the reliability of the PPS; and the validity of the PPS. The PPS is a self-scoring instrument measuring the behavioral responses of people along four dimensions: (1) dominance; (2) influencing; (3) steadiness; and (4) compliance. The instrument is designed to provide a systematic and comprehensive perception of an individual's behavioral tendencies and the behavioral tendencies of …

The purpose of this research study was twofold: 1) to explore if a university’s Master of Science in Project Management students’ MBTI® personalities differ significantly; 2) to gain a better understanding if the MBTI® personality traits of university students enrolled in a project management degree differ significantly from those MBTI® personalities of the general population. The goodness of fit test was used in order to test the hypotheses that the 177 graduate project management students (observed data) have the same MBTI® distribution as in the general population (expected data). Overall, the present study showed that the student population has 27.18% …

Principal components extraction with orthogonal and oblique rotations tested construct validity for the Personal Profile System. MOST-LIKE endorsements of 96 behavioral descriptors were coded with 4, LEAST-LIKE with 1, and unendorsed with 2.5. Descriptor data from 1,045 senior noncommissioned Air Force officers were normalized. Four factors accounted for 85% of total variance, with 19 descriptors loading significantly on two factors and the remaining 77 on just one factor. The measure of sampling adequacy for every descriptor exceeded .94. One factor for the varimax-rotated (best) analysis was bi-scalar, loading on Steadiness and Compliance descriptors; a second resembled Influencing, a third loaded …
