Detection of malingering on the Halstead-Reitan Battery: a cross-validation

Using the Halstead-Reitan Battery profiles of 796 people, a formula for the detection of malingering was cross-validated to assess the false positive rate. Subjects included normals, psychiatric cases, and all major types of organics. The formula incorrectly designated 27% of the sample as fakers (i.e., as false positives). Of the 120 head trauma cases, 27 (22.5%) obtained Fake scores, while 93 (77.5%) were correctly assessed as not malingering.
