    Abstract:
    The Boston Naming Test-Second edition (BNT-2) and the Neuropsychological Assessment Battery-Naming (NAB-N) subtest are two commonly used confrontation naming tests used to evaluate word-finding ability in individuals suspected of neurodegenerative disease. The BNT-2 and NAB-N are designed to measure the same construct; however, observations in practice suggest these two tests provide divergent estimates of naming ability. This study sought to systematically investigate the level of agreement between performance on the BNT-2 and NAB-N. Records from 105 consecutive referrals seen for neuropsychological evaluation as part of routine care in an outpatient memory disorders clinic were reviewed. Discrepancy scores, concordance correlation coefficients, and root mean squared differences were calculated between demographically adjusted T-scores on the BNT-2 and NAB-N. Results indicated that estimates of word finding ability generated by the BNT-2 and NAB-N have a strong linear relationship but systematically generate scores that are inconsistent. Despite similar task demands, the BNT-2 and NAB-N provide different information about naming ability and further research is needed to understand these differences and inform clinicians on interpreting the naming estimates provided by each test.
