Detection of coached general malingering on the MMPI-2.
The current study examined the effects of validity-scale coaching on one's ability to feign general psychopathology. College students were coached on malingering strategies and completed the MMPI-2. Their responses were compared with students asked to malinger psychopathology without validity-scale coaching and with psychiatric inpatients completing the MMPI-2 under standard instructions. In accordance with previous research (e.g., J. R. Graham, D. Watts, & R. E. Timbrook, 1991), uncoached malingerers were adequately discriminated from patients by using the Infrequency (F) scale. However, as suggested by previous research (R. Rogers, R. M. Bagby, & D. Chakraborty, 1993), the F scale was not as effective at classifying coached malingerers. It was found that other validity indicators, such as the Infrequency Psychopathology Scale were more accurate at discriminating between coached malingerers and hospitalized patients.
