Development of an Infrequency-Psychopathology scale for the MMPI-A: the Fp-A Scale.
This article describes the development and initial validation of the Infrequency-Psychopathology scale, Fp-A, for the MMPI-A (Butcher et al., 1992). The scale parallels the Infrequency-Psychopathology scale, F(p), that has been developed for the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). Results demonstrated that the 40-item Fp-A scale is superior to the F scale at discriminating between faking-bad and accurate reports of psychopathology, although the improvement over F was modest, particularly when compared to the improvement found for the F(p) scale. The difference seemed to reflect the superiority of the MMPI-A F scale to the MMPI-2 F scale. Even so, the findings suggest that the identification of overreporting on the MMPI-A could potentially be enhanced by using Fp-A as an adjunct to the F scale.
