The influence of elevated F scales on the validity of adolescent MMPI profiles.

The Minnesota Multiphasic Personality Inventories (MMPI) of adolescent outpatients were examined to determine whether characteristically elevated F scales indicated an exaggeration of psychopathology. A treatment condition designed to reduce the motivation to exaggerate psychopathology did not lower scores of the F and F-K indices when subjects were administered a second MMPI. Similarly, actuarial interpretations for the second protocols were not more frequently selected by therapists as more valid, regardless of treatment condition and elevation of the F and F-K indices on the first MMPI profile. Elevations of Scales F, Pd/4, and Sc/8 characterized the adolescent MMPI profiles.
