The current study examined the over-reporting Validity Scales of the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008/2011) in relation to the Slick, Sherman, and Iverson (1999) criteria for the diagnosis of Malingered Neurocognitive Dysfunction in a sample of 916 consecutive non-head injury disability claimants. The classification of Malingered Neurocognitive Dysfunction was based on scores from several cognitive symptom validity tests and response bias indicators built into traditional neuropsychological tests. Higher scores on MMPI-2-RF Validity Scales, particularly the Response Bias Scale (Gervais, Ben-Porath, Wygant, & Green, 2007), were associated with probable and definite Malingered Neurocognitive Dysfunction. The MMPI-2-RF's Validity Scales …

This paper reports on three psychopathy indices derived from scores on the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008). In Study 1, we describe the development of such indices referenced to the Psychopathic Personality Inventory (PPI; Lilienfeld & Andrews, 1996) and its two distinguishable facets, Fearless-Dominance and Impulsive-Antisociality. We estimated psychopathy scores by regressing PPI scores onto conceptually selected MMPI-2-RF scales in a combined sample of 825 college students and correctional inmates. In Study 2, we explored the construct validity of these psychopathy measures in college student and correctional samples. The measures demonstrated conceptually expected patterns of associations with …

The current study examined the validity scales of the Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2-RF; Ben-Porath and Tellegen 2008) in relation to the structured malingering criteria developed to assess malingered neurocognitive dysfunction and pain-related disability. These criteria examined a sample of 251 individuals undergoing compensation-seeking evaluations, who completed a battery of response bias measures. The MMPI-2-RF over-reporting scales yielded large effect sizes in contrasting those in the probable/definite malingering groups from the incentive only groups. The largest effects were found for the Infrequent Responses and Gervais et al. (Assessment, 14, 196–208, 2007) Response Bias Scale, an experimental scale that …
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
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

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 …
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

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 …
Empirical Correlates And Interpretation Of The Mmpi-2-Rf Cognitive Complaints (Cog) Scale, Roger Gervais, Yossef Ben-Porath, Dustin Wygant
Empirical Correlates And Interpretation Of The Mmpi-2-Rf Cognitive Complaints (Cog) Scale, Roger Gervais, Yossef Ben-Porath, Dustin Wygant

The MMPI-2-RF Cognitive Complaints (COG) scale (Ben-Porath & Tellegen, 2008) was developed to assess self-reported memory and other cognitive difficulties. The present study explores cognitive and self-report correlates of the COG scale and provides recommendations for its interpretation. We examined archival demographic, cognitive test, and self-report symptom data from 1741 consecutive, non-head injury disability claimants seen in a private-practice setting. Insufficient cognitive effort and cognitive symptom exaggeration were controlled by excluding cases that scored in the biased responding range on cognitive symptom validity tests and the Response Bias Scale (RBS). Results of the study found that performance on COG was …
Clinical Utility Of The Mmpi–2 Restructured Clinical (Rc) Scales In Therapeutic Assessment: A Case Study, Dustin Wygant, Karen Fleming
Clinical Utility Of The Mmpi–2 Restructured Clinical (Rc) Scales In Therapeutic Assessment: A Case Study, Dustin Wygant, Karen Fleming

In the following article, we provide a case study on a 25-year-old man who was released from a crisis stabilization unit following a suicide attempt. After completing a diagnostic intake, the client participated in a Therapeutic Assessment (Finn, 1996, 2003), which included the MMPI-2 (Butcher et al., 2001) and the Incomplete Sentences Blank (Rotter & Rafferty, 1950). In particular, in the article, we focus on how the Restructured Clinical (RC; Tellegen et al., 2003) scales can be used to form a personological conceptualization of the client. The RC scales measure important personality and affective trait dimensions including demoralization and both …
