Factoring The Personal Profile System For Construct Validity: Three Analyses Under Different Standardization Assumptions, Thomas G. Henkel, James Noel Wilmoth

Three types of data were factor analyzed using principal components extractions with orthogonal and oblique rotations to test publisher claims for construct validity of the Personal Profile System (PPS). Behavioral descriptor data from 1,045 senior non-commissioned Air Force officers were factored as raw data, mean corrected data, and standardized z-scores (correlations). The most efficacious solution was produced with standardized z-scores generating four factors accounting for 86% of the total variance. The measure of sampling adequacy for every descriptor exceeded 0.922. The first factor was general with approximately equal loadings on each of the dominance, influencing, steadiness, and compliance dimensions. The …
Improving The Sensitivity Of The Vrin-R Scale On The Mmpi-A-Rf, Stefan E. Latulip
Improving The Sensitivity Of The Vrin-R Scale On The Mmpi-A-Rf, Stefan E. Latulip
Psychology Theses & Dissertations
When respondents to self-report measures fail to answer in accordance with item content it distorts the accuracy of obtained test scores, degrading the ability of clinicians to use results to make accurate diagnoses and recommendations. The Variable Response Inconsistency (VRIN) scale was created for the MMPI-2 and was later revised as the VRIN-r scale for the MMPI-2-RF and MMPI-A-RF in order to detect and invalidate protocols over saturated with random responding. Analyses conducted by Pitta (2016) revealed that the VRIN-r scale for the MMPI-A-RF was not ideally sensitive to the detection of random responding in protocols. This study explored adding …
