T-score and raw-score comparisons in detecting brain dysfunction using the booklet category test and the short category test.
Often considered one of the more discriminating tests between normal and brain-damaged individuals, the Category Test has been described as a complex measure of new problem solving, logical analysis, concept formation, abstract reasoning, and mental efficiency. Since publication of a booklet format by DeFilippis and McCampbell in 1979, researchers have attempted to develop other versions to reduce time required for administration. The present study compared the sensitivity of the Short Category Test, Booklet Format with the Booklet Category Test. Subjects were 22 male veterans seen for comprehensive neuropsychological evaluation and were classified into a brain-damaged or a control group (ns =11) according to independent neurological or neuroradiological evidence. Comparison of performances based on T scores yielded no significant differences between the groups on either format. Analyses of performance based upon suggested raw score cut-offs for the tests, however, yielded a statistically meaningful difference, but caution is in order when using T scores derived from age- or education-based normative data to suggest the presence of brain dysfunction. Raw score cut-offs yielded valid differentiation of individual patients in both groups.[1]References
