A partial cross-validation of a Halstead-Reitan Battery malingering formula.
Using the Halstead-Reitan Battery profiles of 796 people, a formula for the detection of malingering was partially cross-validated to assess the false positive rate. Subjects included normals, psychiatric cases, and persons with all major types of brain disorder. The formula incorrectly designated 32% of the sample as fakers (i.e., as false positives). Of the 120 head-trauma cases, 39 (32%) obtained Fake scores, whereas 81 (67%) were correctly assessed as not malingering. The correlation of the results of the formula and the severity of the profile (as measured by the Average Impairment Rating) was 67, p < .0001.
