The Minnesota Multiphasic Personality Inventory – 2 Restructured Form (MMPI-2- RF; Tellegen & Ben-Porath, 2008/2011) is a widely used self-report measure of psychopathology and personality. However, the self-report format of the MMPI-2-RF suggests that interpretation of its scales and the clinical recommendations that follow are vulnerable to invalid response styles. This dissertation builds upon previous research (Handel, Ben-Porath, Tellegen, & Archer, 2010) to examine the effect of random and fixed responding, as measured by the VRIN-r and TRIN-r Scales, on the 28 SP and PSY-5 Scales. A computer simulation procedure was used to insert increasing degrees of inconsistent responding into protocols from two large samples (N = 2, 276 and N = 704). Results indicated that increasing degrees of inconsistent responding increase SP and PSY-5 Scale mean T-scores and weaken external criterion validity. Further, certain SP and PSY-5 Scales evidenced large changes in mean T-scores at relatively low levels of simulated inconsistent responding. Implications of these results and future areas of investigation are discussed.
