Abstract
Conducted this study to cross-validate the Verbal Concept Attainment Test as a measure of potential value in neuropsychological assessment and to booklet form of this test. Two samples of 75 patients referred for neuropsychological examination were studied. In both samples the pattern of relationship between the VCAT and a number of widely used neuropsychological measures closely paralleled the pattern reported in the initial validation study. The pattern of relationships with the booklet form was also very similar to the pattern of relationships between the neuropsychological measures and the Impairment Index from the Halstead-Reitan Battery. It was concluded that these data provided evidence of the stability of this test across samples and that the booklet form appeared to be equally valid measure.
