Diagnostic scoring of the Halstead-Reitan category test

Abstracts from the 19th Annual Meeting
were assessed to examine how they relate to performance on the BCT: basic attention (Trail Making Test, Part A); visual memory (Visual Reproduction subtest of the WMSR); visuoperceptual skills (Judgment of Line Orientation Test); perceptual-organization (Perceptual Organization Index of the WAIS-R); and cognitive flexibility and concept formation (Trail Making Test, Part B; Wisconsin Card Sorting Test). The results of multiple regression analyses revealed the following pattern: performance on BCT Subtest I was most strongly related to visuoperceptual skills; performance on Subtest 2 was most strongly related to visual memory; performance on Subtest 3 was most strongly related to cognitive flexibility; performance on Subtest 4 was most strongly related to visual memory; performance on Subtest 5 was most strongly related to perceptual-organizational skills and visual memory; performance on Subtest 6 was most strongly related to visuoperceptual skills and visual memory; and performance on Subtest 7 was most strongly related to perceptual-organizational skills and visual memory. As expected, concept formation and cognitive flexibility significantly predicted the BCT Total Error Score. Altogether, the five aforementioned cognitive domains accounted for 90% of the variance in the BCT Total error score. However, performance on the individual BCT subtests was not significantly related to basic attentional skills. The results of this study suggest that, at least within a heterogeneous brain injured population, neuropsychological performance substrates on the BCT include visual memory, visuoperceptual skills, perceptual-organizational skills, and concept formation/cognitive flexibility.
Stone, M. H., & Thompson, E. Diagnostic Scoring of the Halstead-Reitan Category Test. The Halstead-Reitan Category Test is well-known to neuropsychologists. Research has substantiated its sensitivity to brain damage. Unfortunately, the single interpretive score is the number of errors made by the examinee. There is no diagnostic interpretive approach readily available to the clinician. This study has produced an interpretive form to assist the clinician in making further diagnosis. The subjects for the development of this form consisted of 90 male offenders recently released and required to participate in treatment. Their crimes consisted of rape, assault, and molestation. Treatment was predicated on a comprehensive assessment including the Category Test: computer versionresearch edition (DeFilippis, 1993). Total errors, total test time and item response and time were the test variables. The Category Test items involve increasingly complex variations of past items. The total score does not address this matter and so all the test items have been categorized by their similar or dissimilar construction. The result is a diagnostic form that elucidates the response profile of the examinee according to the problem characteristics of the item (i.e., type of problem and similarity or dissimilarity to previous item). Test reliability (internal) for this sample was .95. Examinees' responses were more meaningfully interpreted by this interpretive method than by consideration only of the total count of errors made. Differences between types of offenses were not significant. However, the profiles were judged by clinicians to be more meaningful in planning treatment and understanding the disability of the person.

The Hooper Visual Organization Test (HVOT) is a commonly used measure of visual perceptual function. However, serious questions have been recently raised about its construct validity. This study further examined its construct validity and explored its contribution to outcome prediction in stroke rehabilitation. Subjects were 101 patients (mean
