Construct validity of the computerized version of the Category Test.
The purpose of the current study was to investigate the construct validity of the computer version of the Category Test (CT) in relation to the standard version. As part of a comprehensive neuropsychological assessment, outpatient rehabilitation clients completed either the standard CT (n = 49) or the computerized version (n = 56). Two principal component factor analyses were performed and the factor structures compared to a solution reported previously in the literature. Inspection of the factor loadings revealed a similarity between the computerized CT and standard CT groups as well as with the previously reported analysis. The results of this study suggest that regardless of the mode of administration the CT loads on a "spatial abilities", factor and provides support for the construct validity of the computerized CT as part of a comprehensive neuropsychological testing battery.
