Geriatric performance on an abbreviated version of the Boston naming test.
Abbreviated neuropsychological protocols are increasingly utilized secondary to time-constraints within research and healthcare settings, yet normative data for these abbreviated instruments are lacking. We present geriatric performances and normative data for the Boston Naming Test 30-item even version (BNT-30). Data were utilized from the BU-ADCC registry (n = 441, ages 55-98) and included 219 normal controls (NC), 155 participants with mild cognitive impairment (MCI), and 67 participants with Alzheimer's disease (AD). The NC group (M = 28.7, SD = 1.8) significantly outperformed both MCI (M = 26.2, SD = 4.4) and AD (M = 22.1, SD = 4.8) groups, and the MCI group outperformed the AD group. Normative data generated for the NC participants revealed a significant between-group difference for sex (males M = 29.1, SD = 1.7; females M = 28.4, SD = 1.8) and race (White M = 28.8, SD = 1.7; African American M = 27.5, SD = 2.1). The racial disparity remained even after adjusting for education level (p = .002) and literacy (p < .001). ANOVAs for the NC group were non-significant for age but significant for education level (p = .001). Geriatric normative data therefore suggest that sex, race, and education are all associated with naming performance, and these variables should be taken into consideration when interpreting geriatric BNT-30 performance.
