ACCURACY OF THE MMPI-2 COMPUTERIZED MINNESOTA REPORT IN IDENTIFYING FAKE-GOOD AND FAKE-BAD RESPONSE SETS

The present simulation study was designed to evaluate the accuracy of the computerized Minnesota Report in identifying faked response sets o n the Minnesota Multiphasic Personality Inventory (MMPI-2). The Minnes ota Report is being increasingly relied upon in forensic neuropsycholo gical assessments to assist in identifying malingering. Three groups o f 18 students were given different sets of instructions: fake-good, fa ke-bad, and the standard instructions. Of those participants instructe d to fake-good, the classification rate was 94% with only one particip ant misclassified as providing a ''normal'' profile. Of those particip ants instructed to fake-bad, 100% were correctly classified by the Min nesota Report. Of those who completed the MMPI-2 under standard instru ctions 78% were classified as having ''normal'' profiles, whereas 22% were classified as faking-good. The value of the Minnesota Report in i dentifying fake-bad response sets was amply demonstrated, and it is su ch performances that may be helpful in detecting malingering in forens ic evaluations.
