Utility of the response bias scale (RBS) and other MMPI-2 validity scales in predicting TOMM performance.

The present study represents a replication and extension of the original Response Bias Scale (RBS) validation study. In addition to examining the relationship between the Test of Memory Malingering (TOMM), RBS, and several other well-researched Minnesota Multiphasic Personality Inventory 2 (MMPI-2) validity scales (i.e., F, Fb, Fp, and the Fake Bad Scale), the present study also included the recently developed Infrequency Post-Traumatic Stress Disorder Scale and the Henry-Heilbronner Index (HHI) of the MMPI-2. Findings from this retrospective data analysis (N=46) demonstrated the superiority of the RBS, and to a certain extent the HHI, over other MMPI-2 validity scales in predicting TOMM failure within the outpatient Veterans Affairs population. Results of the current study confirm the clinical utility of the RBS and suggest that, particularly if the MMPI-2 is an existing part of the neuropsychological assessment, examination of RBS scores is an efficient means of detecting negative response bias.
