Statistical and diagnostic adequacy of a short form of the Halstead Category Test.
The current study examined the statistical adequacy of shortened versions (SF) of the Halstead Category Test (CT) through several multiple regression analyses (MRA), using a large sample (N = 1012) of neurologically- referred patients to allow for reasonable confidence in the reliability of the findings. The diagnostic accuracy of the psychometrically soundest short form (consisting of subtests 4, 6, and 3) was then compared to that of the long form on a subsample of 590 patients from the first study for whom brain damage had either been medically confirmed or ruled out. Results suggest that a short form may be psychometrically feasible, with little loss in diagnostic accuracy.
