The Halstead Category Test of Brain Dysfunction: Feasibility of a Short Form

Although the Halstead Category Test is one of the best indicators of brain dysfunction among the subtests of the Halstead-Reitan Neuropsychological Test Battery, it has been used infrequently by psychologists in clinical settings. The feasibility of a short form was considered. For the test protocols of 41 Ss the product-moment correlation for errors on odd items and total errors was .90, on even items and total errors, .99. The split-half correlation was .97. Research on the discriminative power of a short form was discussed; a short form is apparently feasible for use by the psychologist.
