Detection of symptom underreporting on the MMPI-2

Abstract

The Minnesota Multiphasic Personality Inventory (MMPI-2) was administered to 122 female kindergarten teacher applicants, once with standard instructions, again with scripted experimental instructions (honest or underreporting). Underreporting instructions produced higher scores on L, K, S, and L+K, and lower scores on F and F-K than standard and honest instructions. Some clinical scale scores produced under underreporting conditions were significantly different from those produced under standard and honest conditions. Consistent with the previous report, L and L+K were effective in identifying underreporting profiles. The new S scale, although developed using samples of men, faired quite well. Overall, cutting scores suggested by Baer et al. (1993) showed fairly positive results. Although S failed to outperform L and L+K in discriminating between the underreporting and standard profiles, further research is needed to explore the discriminative power of the S scale.
