Psychometric Functioning of The MMPI-A Restructured Form VRIN-R, TRIN-R, CRIN, and Cannot Say Scales with Varying Degrees of Randomness, Acquiescence, Counter-Acquiescence, and Omitted Items
The MMPI-A-RF (Archer, Handel, Ben-Porath & Tellegen, 2016) is a new measure of adolescent personality and psychopathology derived from the MMPI-A (Butcher, Williams, Graham, Archer, Tellegen, Ben-Porath & Kaemmer, 1992) item pool. Similar to the MMPI-A, the MMPI-A-RF includes indexes designed to assess non-content-based responding and omitted items. Building on Handel, Ben-Porath, Tellegen & Archer’s study (2010) on adults, the current study utilized computer simulation of random, acquiescent, counteracquiescent, and omitted responses to examine how adolescent validity scale and RC scale scores are affected by increasing degrees of non-content-based responding. Further, RC scale validity coefficients were examined to see how increasing degrees of non-content-based responding attenuates these relationships. Lastly, this study examines the moderating effects of VRIN-r and TRIN-r on the relationship between RC scale and extra-test variables. Results showed that MMPI-A-RF content non-responsiveness does have a predictable impact on validity scale scores, RC scale scores, and clinical scale relationships through changes in mean T-scores, degradation of validity coefficients, and significant moderating effects. Limitations and implications of the current study are addressed.
