The effects of knowledge of psychiatry and psychological testing on the ability to feign schizophrenia on the Minnesota Multiphasic Personality Inventory were studied with 54 clinically trained participants, 24 undergraduates with no clinical training, and 51 patients. Results suggest that even mental health professionals have difficulty feigning…

Effects of random responding and malingering on Minnesota Multiphasic Personality Inventory 2 (MMPI-2) validity scales were studied with 173 graduate and undergraduate University of Kentucky (Lexington) students. Inconsistent responding and malingering produced significant elevations on the validity scales, with the dissimulation scale appearing…

The ability of persons faking posttraumatic stress disorder or head injury to respond consistently across serial testings on the Minnesota Multiphasic Personality Inventory-2 was studied with 118 undergraduates. Results suggest that test takers can fake and describe symptoms consistently, and that type of disorder may affect temporal response…

The content scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), designed to assess substantive dimensions of psychopathology, were evaluated through responses of 221 undergraduates. Results indicate that the convergent and discriminant validity of MMPI-2 content scales are compromised by substantial confounding general variance.…

The impact of detailed information on closed head injury (CHI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales on malingering psychological symptoms of CHI on the MMPI-2 was studied in an analog experiment with 270 undergraduates. Results suggest the impact of such coaching on simulation of CHI. (SLD)

In 3 studies involving a total of 305 undergraduates, the Antisocial Practices (ASP) scale of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) exhibited convergent and discriminant validity with other measures of personality. The ASP and the Psychopathic Deviant scale appear to measure different facets of psychopathy. (SLD)

Thurstone's scaling based on judgments of 527 students and 37 clinical faculty members was applied to the Beck Depression Inventory, the Zung Depression Scale, and the Minnesota Multiphasic Personality Inventory and fitted the observed data well. A psychological continuum was derived for severity of depression. (SLD)

A study with 804 undergraduates finds that Minnesota Multiphasic Personality Inventory-2 protocols that contain random responding with an onset after item 370 can be distinguished from protocols with an earlier onset of random responding. Results suggest that protocols with late random responding may be interpretable in terms of basic clinical and…

Comparability of the Minnesota Multiphasic Personality Inventory (MMPI) and the MMPI-2 was explored by examining T-score means, profile configurations, score distribution, and rank-order correlations on validity scales for 84 undergraduates. Equivalency of the two forms was generally supported. (SLD)

Patterns of responses to the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) that typify deliberate deception of others (faking good) were studied using 100 undergraduates at the University of Alabama (Tuscaloosa) who were given extra course credit for participation in the study. Females constituted 73% of the final subject pool. Each…

The efficacy of 5 scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) in detecting fake good, fake bad, and honest profiles was investigated for 110 undergraduate students instructed to fake good, fake bad, or respond honestly. An analysis of variance suggests that these validity scales are useful. (SLD)
