Equivalence of Laptop and Tablet Administrations of the Minnesota Multiphasic Personality Inventory-2 Restructured Form.

The present study investigated the comparability of laptop computer- and tablet-based administration modes for the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF). Employing a counterbalanced within-subjects design, the MMPI-2-RF was administered via both modes to a sample of college undergraduates ( N = 133). Administration modes were compared in terms of mean scale scores, internal consistency, test-retest consistency, external validity, and administration time.

Utility of the MMPI-2-RF Validity Scales in Detection of Simulated Underreporting: Implications of Incorporating a Manipulation Check.

We examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) underreporting Validity Scales in a simulation design with a sample of 257 undergraduate college students. Extending past research by Sellbom and Bagby, we added a manipulation check to determine whether individuals complied with instructions to underreport and examined the impact of underreporting on all of the MMPI-2-RF substantive scales. Results indicated that individuals who complied with instructions to underreport produced statistically significantly and meaningfully higher scores on the MMPI-2-RF underreporting Validity Scales (Uncommon Virtues [L-r] and Adjustment Validity [K-r]) when compared with those who received standard instructions and with individuals who did not comply with instructions to underreport.

The Generalizability of Overreporting Across Self-Report Measures: An Investigation With the Minnesota Multiphasic Personality Inventory-2-Restructured Form and the Personality Assessment Inventory in a Civil Disability Sample.

Elevated overreporting Validity Scale scores on the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) are associated with higher scores on collateral measures; however, measures used in prior research lacked validity scales. We sought to extend these findings by examining associations between elevated MMPI-2-RF overreporting scale scores and Personality Assessment Inventory (PAI) scale scores among 654 non-head injury civil disability claimants. Individuals were classified as overreporting psychopathology (OR-P), overreporting somatic/cognitive complaints (OR-SC), inconclusive reporting psychopathology (IR-P), inconclusive reporting somatic/cognitive complaints (IR-SC), or valid reporting (VR).

Embedded effort scales in the repeatable battery for the assessment of neuropsychological status: do they detect neurocognitive malingering?

The current study examined two embedded response bias measures in the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), the Effort Index (EI) and Effort Scale (ES), in relation to Malingered Neurocognitive Dysfunction criteria. We examined 105 individuals undergoing compensation-seeking disability evaluations. The results suggest the EI adequately differentiates the Probable/Definite Malingering group from the Incentive Only and Possible Malingering groups, while the ES does not, which is most likely representative of the current sample of disability litigants rather than its intended population of patients with amnesia.

Can brief measures effectively screen for pain and somatic malingering? Examination of the Modified Somatic Perception Questionnaire and Pain Disability Index.

Background Context: Recent rise in fraudulent disability claims in the United States has resulted in psychologists being increasingly called upon to use psychological tests to determine whether disability claims based on psychological or somatic/pain complaints are legitimate.

Purpose: To examine two brief measures, Modified Somatic Perception Questionnaire (MSPQ) and the Pain Disability Index (PDI), and their ability to screen for malingering in relation to the Bianchini et al. criteria for malingered pain-related disability published in The Spine Journal (2005).

It's not all in your head (or at least your brain): association of traumatic brain lesion presence and location with performance on measures of response bias in forensic evaluation.

This study examined the relationship between lesion presence and localization and performance on measures of cognitive response bias, specifically in individuals purporting to have a traumatic brain injury. Ninety-two participants, all of whom were involved in workers' compensation or personal injury litigation, were administered an extensive neuropsychological battery, including neuroimaging (magnetic resonance imaging and computed tomography), at a neuropsychiatric clinic in Lexington, KY. Those with evidence of intracranial injury on neuroimaging findings were placed in the head injury lesion litigation group and were coded based on the anatomical location and type of intracranial injury.
