INTERRELATIONSHIP OF MMPI-2 VALIDITY SCALES IN PERSONAL-INJURY CLAIMS

A sample of MMPI-2s of worker's compensation and personal injury cases (N = 289) was gathered to examine the relationship of various indicat ors of exaggeration. Intercorrelations of the F, F - K, the MMPI Dissi mulation Scale-revised (Ds-r), total of obvious minus subtle scales (O - S), Fake Bad Scale (FBS), VRIN, and TRIN were computed and the rela tive sensitivity of each score calculated using various cut-offs. Fact or analysis suggests that malingering may take the form of inconsisten t responding as well as symptom exaggeration. Patients evaluated at th e request of plaintiff attorneys showed a seemingly greater degree of symptom exaggeration and inconsistent responding than did those referr ed by defense counsel.
