This article examined the impact of unscorable item responses on the psychometric validity and practical interpretability of scores on the Restructured Clinical (RC) Scales of the Minnesota Multiphasic Personality Inventory-2/Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2/MMPI-2-RF). In analyses conducted with five…

In the present study, the authors explored the meaning of low scores on the MMPI-2/MMPI-2-RF Restructured Clinical (RC) scales. Using responses of a sample of university students (N = 811), the authors examined whether low (T less than 39), within-normal-limits (T = 39-64), and high (T greater than 65) score levels on the RC scales are…

The ability to screen quickly and thoroughly for psychological difficulties in existing and returning combat veterans who are seeking treatment for physical ailments would be of significant benefit. In the current study, item and time savings, as well as extratest correlations, associated with an audio-augmented version of the computerized…

In the present study, the authors evaluated the effects of increasing degrees of simulated non-content-based (random or fixed) responding on scores on the newly developed Variable Response Inconsistency-Revised (VRIN-r) and True Response Inconsistency-Revised (TRIN-r) scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form…

The present study extends the validation of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) and the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) Response Bias Scale (RBS; R. O. Gervais, Y. S. Ben-Porath, D. B. Wygant, & P. Green, 2007) in separate forensic samples composed of disability claimants and…

This study examined the impact of overreporting on the validity of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) substantive scale scores by comparing correlations with relevant external criteria (i.e., validity coefficients) of individuals who completed the instrument under instructions to (a) feign psychopathology…

We examined the convergent and discriminant validity of the Minnesota Multiphasic Personality Inventory--2 (MMPI--2) measures of psychopathy, including the Clinical Scale 4, Restructured Clinical Scale 4 (RC4), Content Scale Antisocial Practices (ASP), and Personality Psychopathology Five Scale Disconstraint (DISC). Comparisons of the empirical…

The Minnesota Mutiphasic Personality Inventory-2 (MMPI-2)-based Personality Psychopathology-Five (PSY-5) scales provide an overview of personality individual differences. Several textbooks and a test report offer instruction on interpreting MMPI-2 PSY-5 scores. On the basis of an earlier item response theory article (S. V. Rouse, M. S. Finger,…

This study describes the development of a Minnesota Multiphasic Personality Inventory (MMPI-2) scale designed to detect negative response bias in forensic neuropsychological or disability assessment settings. The Response Bias Scale (RBS) consists of 28 MMPI-2 items that discriminated between persons who passed or failed the Word Memory Test…

The effectiveness of the Infrequency-Psychopathology Scale (P. Arbisi and Y. Ben-Porath, 1995) in discriminating between groups of patients administered the Minnesota Multiphasic Personality Inventory--2 under honest and fake-bad conditions was studied with 74 patients. Results support use of the scale in detecting malingering in psychiatric…

Issues related to use of "normal" personality inventories in clinical assessment are discussed, including use of the NEO Personality Inventory (NEO-PI) in clinical assessment. It is concluded that there is insufficient evidence to support the use of the NEO-PI for differential diagnoses of psychopathology. (SLD)

The meaning of low scores on some Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scales was examined by comparing therapists' descriptors of 669 mental health patients with high, normal, or low scores on each scale. Results show that for most scales both high and low scores provide potentially important information. (SLD)

The development of Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) scales to measure the Personality Psychopathology Five (PSY-5), a model of personality, is reported. Preliminary scales were refined with the MMPI-A normative sample of 1,620 and a clinical sample of 713 adolescents, and their construct validity was supported. (SLD)

A new infrequent response indicator, frequency psychopathology [F(p)] was developed for the Minnesota Multiphasic Personality Inventory (MMPI) and tested with 308 male psychiatric inpatients (veterans). Findings support the F(p) as a sensitive index of profile invalidity in psychiatric populations. (SLD)

The authors examined and compared the susceptibility of three Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scale sets (Clinical, Restructured Clinical [RC], and Content) to over- and underreporting using five analog samples. Two samples of 85 and 191 undergraduate students, respectively, took the MMPI-2 under underreporting versus…
