Bagby, R. M., Nicholson, R. A., Buis, T., & Bacchiochi, J. R. (2000). Can the MMPI-2 validity scales detect depression feigned by experts? Assessment, 7(1), 55-62.
The capacity of a number of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) validity scales and indicators to detect feigned depression was examined. 23 mental health professionals (mean age 37.2 yrs) with specific expertise and significant experience in assessing and treating major depression were asked to complete the MMPI-2 as if they were suffering from major depression. The MMPI-2 protocols of this sample were compared to those of a sample of 50 patients diagnosed with major depression. The results indicated that the validity scales F, back F (F-sub(B)), and the Dissimulation scale (Ds) were highly successful at distinguishing MMPI-2 protocols of feigned depression from bona fide depression. Replicating results from previous studies, however, F-sub(B) proved most effective, outperforming all other validity scales and indicators, including F and Ds. Findings suggest that even experts are unable to feign major depression successfully on the MMPI-2, and that the F-sub(B) scale might be the most effective indicator for detecting feigned depression.
