The efficacy of the Mp and X minus zero scales of the MMPI in identifying fake-good profiles was investigated. 30 volunteers from the admissions unit of a state mental hospital were administered the MMPI once under instructions to fake good and once under standard instructions. Under fake-good instructions, psychiatric inpatients were able to produce profiles similar to those of normal college students. Both the Mp and X minus zero scales discriminated significantly between the standard and fake-good profiles. Interactions with order of administration occurred for the Mp scale.
