Association of the MMPI-2 Restructured Form (MMPI-2-RF) Validity Scales with Structured Malingering Criteria

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 can be scored on the MMPI-2-RF. Classification analyses were also utilized to examine various cut scores for the individual validity scales, as well as their use in combination. These results suggest that the MMPI-2-RF validity scales can be used to screen for malingering, as they exhibited good sensitivity at lower cutoffs. The implications of these results and their use in forensic evaluations are discussed
