Utility Of The Mmpi-2-Rf In Detecting Non-Credible Somatic Complaints, Martin Sellbom, Dustin Wygant, Michael Bagby

Dustin B. Wygant

We examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) validity scales (infrequent responses (F-r), infrequent psychopathology responses (Fp-r), infrequent somatic responses (Fs), symptom validity (FBS-r), and response bias (RBS)) in differentiating individuals who were asked to feign physical health problems from a group of somatoform disorder patients and genuine medical patients with no history of mental health problems. A large group of undergraduate students were instructed to feign physical health problems as if they were participating in a disability evaluation for a work-related injury. Comparison groups were drawn from archival databases and consisted of non-litigating medical patients …

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 …
