Naming test of the Neuropsychological Assessment Battery: convergent and discriminant validity.

This study investigated the convergent and discriminant validity of the naming subtest of the Neuropsychological Assessment Battery (NAB), a measure of word-finding. Seventy community-dwelling adults age 60 and above completed the NAB naming test (Forms 1 and 2), the Boston Naming Test (BNT), and other measures of verbal and visual memory, visuoperceptual skills, processing speed, and abstraction. The NAB naming test correlated highly with the BNT and with established measures of memory. The BNT correlated more strongly with education and with sex. The BNT correlated more strongly with a measure of visuoperceptual skills than the NAB naming test did, suggesting that visuoperception is more involved in the BNT. Divergent validity of the NAB naming was demonstrated by a lack of correlations with less-related measures. Findings suggest that the NAB naming test possesses convergent and divergent validity as a measure of word-finding.
