Both the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al., 2001) and Personality Assessment Inventory (PAI; Morey, 1991) offer a large set of scales devoted to the identification of response styles. This study directly compared the effectiveness of the 2 inventories as indicators of overreporting. The 2 measures were administered to 52 college students instructed to fake bad under conditions describing either a forensic (n = 24) or psychiatric (n = 28) setting as well as to 432 psychiatric patients. Results indicated that the MMPI-2 F - K index and Fp Scale were the best single indicators of a faking bad response style and that the MMPI-2 scales were the better indicators as a set. However, the PAI scales demonstrated a significant level of incremental validity over the MMPI-2 indicators in every analysis conducted. The findings suggest that either inventory offers an effective approach to the detection of overreporting, and administering both inventories can enhance the accuracy of prediction further.

To date, relatively few studies have been published evaluating the validity or incremental validity of the content scales from the adolescent version of the Minnesota Multiphasic Personality Inventory (MMPI-A; J. N. Butcher et al., 1992). A sample of 629 psychiatric inpatient adolescents who had completed the MMPI-A was used to evaluate the ability of selected clinical and content scales to predict conceptually related clinical variables. Criteria were based on clinician ratings, admission and discharge diagnoses, and chart reviews. Results from hierarchical multiple and logistic regression analyses indicated the content scales offered incremental validity over the clinical scales and supported the use of the content scales as an adjunct to the traditional clinical scales.

Prior research has examined the relationship between personality characteristics and problematic behaviors, suggesting the utility of self-report personality measures in assessing risk of aggression. This study examined the relationship between select Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF) scales and estimated psychopathy indices derived from MMPI-2-RF scales, and institutional aggression among hospitalized pre-trial defendants. Scores on Thought Dysfunction (THD), Aberrant Experiences, Juvenile Conduct Problems, and Psychoticism-Revised (PSYC-r) were associated with mild-severe aggression. Similarly, THD and PSYC-r were associated with moderate-severe aggression. Regarding psychopathy, impulsive-antisociality, but not fearless-dominance, was associated with both aggressive outcomes. Overall, the relevant MMPI-2-RF scales demonstrated higher classification accuracy than the estimated psychopathy indices. [ABSTRACT FROM PUBLISHER]
