Further Validation Of The Mmpi-2 And Mmpi-2-Rf Response Bias Scale: Findings From Disability And Criminal Forensic Settings, Dustin Wygant, Martin Sellbom, Roger Gervais

Dustin B. Wygant

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 criminal defendants. Using cognitive symptom validity tests as response bias indicators, the RBS exhibited large effect sizes (Cohen's ds = 1.24 and 1.48) in detecting cognitive response bias in the disability and criminal forensic samples, respectively. The scale also added incremental prediction to the traditional MMPI-2 and the MMPI-2-RF overreporting validity scales …

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 …
