MMPI-2 studies have emphasized the importance of establishing validity indices for the evaluation of over reporting and malingering. In this study, 42 chronic outpatients are administered the MMPI-2 under honest and feigning conditions. Results indicated that patients under honest conditions have elevated scores on F, Fb, and other validity scales. Therefore, stringent cutting scores are recommended to minimize the misclassification of bona fide patients as malingerers. Toward this end, F > 29 produced a highly accurate classification rate, whether subjects with high VRIN scores were excluded. In addition, the newly derived Fp scale appeared promising for subjects with low VRIN scores and deserves further investigation.
