DETECTION OF MALINGERING ON THE HALSTEAD-REITAN BATTERY - A CROSS-VALIDATION

Using the Halstead-Reitan Battert profiies of 796 people, a formula fo r 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 c ases, 27 (22.5%) obtained Fake scores, while 93 (77.5%) were correctly assessed as not malingering. (C) 1997 National Academy of Neuropsycho logy.
