ORDER EFFECTS IN THE ADMINISTRATION OF A FORCED-CHOICE PROCEDURE FOR DETECTION OF MALINGERING IN DISABILITY CLAIMANTS EVALUATIONS

100 disability claimants of the Social Security Administration referre d for neuropsychological evaluation and 40 undergraduate college stude nts asked to simulate brain damage were administered a measure for the detection of malingering, an abbreviated version of the Hiscock Force d-choice Procedure, and other neuropsychological tests. Half of each g roup was administered the Hiscock Procedure at the beginning of the ba ttery; the other half was administered this test last. For both groups , the results indicated poorer performance on the earlier administrati on of the abbreviated Hiscock Forced-choice Procedure. Formal measures for detection of malingering should be an integral and early part of any neuropsychological evaluation in which the subject has a financial incentive to perform poorly.
