Rm. Bagby et al., RELATIVE EFFECTIVENESS OF THE STANDARD VALIDITY SCALES IN DETECTING FAKE-BAD AND FAKE-GOOD RESPONDING - REPLICATION AND EXTENSION, Psychological assessment, 7(1), 1995, pp. 84-92
The effectiveness of the Minnesota Multiphasic Personality Inventory-2
(MMPI-2; J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, &
B. Kaemmer, 1989) Lie (L) and Infrequency (F) scales, relative to the
Obvious-Subtle Index (O-S), the Positive Malingering (Mp) scale, and
the revised Dissimulation scale in the detection of fake-good and fake
-bad MMPI-2 protocols was evaluated by asking college students to resp
ond honestly, fake bad, or fake good on the MMPI-2. MMPI-2 protocols o
f participants asked to fake bad were compared with protocols from gen
eral psychiatric and forensic inpatient samples, and MMPI-2 protocols
of participants asked to fake good were compared with MMPI-2 protocols
of students asked to respond honestly. The F scale was superior in de
tecting faking bad, and the O-S index and the Mp and L scales were equ
ally effective at detecting faking good. However, we caution against t
he use of the O-S index in the detection of fake-bad and fake-good res
ponding.
