DETECTION OF MALINGERING ON THE LURIA-NEBRASKA NEUROPSYCHOLOGICAL BATTERY - AN INITIAL AND CROSS-VALIDATION

A formula for detecting faked LNNB profiles was validated on 68 experi mental malingerers and adequately motivated patients marched on educat ion, age, and severity of profile. The formula was then cross-validate d on 51 malingerers and 202 patients. The formula yielded a cross-vali dated 23% Salse negative rate and a 9% false positive rate, for an ove rall hit rate of 88%. If normal and profoundly impaired profiles are e liminated from the cross-validation analysis, the false negative rate is 17% and the false positive rate 7%, for an overall hit rate of 91%.
