Incremental Validity Of The Mmpi-2-Rf Over-Reporting Scales And Rbs In Assessing The Veracity Of Memory Complaints, Roger O. Gervais, Yossef S. Ben-Porath, Dustin Wygant, Martin Sellbom

Dustin B. Wygant

The Response Bias Scale (RBS) has been found to be a better predictor of over-reported memory complaints than Minnesota Multiphasic Personality Inventory-2 (MMPI-2) F, Back Infrequency (Fb), Infrequency-Psychopathology (Fp), and FBS scales. The MMPI-2-Restructured Form (RF) validity scales were designed to meet or exceed the sensitivity of their MMPI-2 counterparts to symptom over-reporting. This study examined the incremental validity of MMPI-2-RF validity scales and RBS in assessing memory complaints. The MMPI-2-RF over-reporting validity scales were more strongly associated with mean Memory Complaints Inventory scores than their MMPI-2 counterparts

(d ¼ 0.22 to 0.49). RBS showed the strongest relationship with memory …

Utility Of The Mmpi–2-Rf (Restructured Form) Validity Scales In Detecting Malingering In A Criminal Forensic Setting: A Known-Groups Design, Martin Sellbom, Joseph A. Toomey, Dustin B. Wygant, L. Thomas Kucharski, Scott Duncan

Dustin B. Wygant

The current study examined the utility of the recently released Minnesota Multiphasic Personality Inventory—2 Restructured Form (MMPI–2-RF; Ben-Porath & Tellegen, 2008) validity scales to detect feigned psychopathology in a criminal forensic setting. We used a known-groups design with the Structured Interview of Reported Symptoms (SIRS; Rogers, Bagby, & Dickens, 1992) as the external

criterion to determine groups of probable malingering versus nonmalingering. A final sample of 125 criminal defendants, who were administered both the SIRS and the MMPI–2-RF during their evaluations, was examined. The results indicated that the two MMPI–2-RF validity scales specifically designed to detect overreported psychopathology, F-r and …

Examination Of The Mmpi-2 Restructured Form (Mmpi-2-Rf) Validity Scales In Civil Forensic Settings: Findings From Simulation And Known Group Samples, Dustin Wygant, Yossef Ben-Porath, Paul Arbisi, David Berry, David Freeman, Robert Heilbronner

Dustin B. Wygant

The current study examined the effectiveness of the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath and Tellegen, 2008) over-reporting indicators in civil forensic settings. The MMPI-2-RF includes three revised MMPI-2 over-reporting validity scales and a new scale to detect over-reported somatic complaints. Participants dissimulated medical and neuropsychological complaints in two simulation samples, and a known-groups sample used symptom validity tests as a response bias criterion. Results indicated large effect sizes for the MMPI-2-RF validity scales, including a Cohen's d of .90 for Fs in a head injury simulation sample, 2.31 for FBS-r, 2.01 for F-r, and 1.97 for Fs in a medical …
