Short Description of Instrument
The 30-item version of the Boston Naming Test (BNT) was designed to differentiate between Alzheimer's disease (AD) and normal subjects. This version is useful for repeated assessments of a naming task, as well as in situations where administration of the complete BNT is not practical (Mack et al., 1992).
The BNT and its short forms are tasks of visual confrontation naming, sensitive to deficits in semantic retrieval. Norms for this 30-item version were developed using a registry including normal controls, mild cognitive impairment (MCI), and AD (Jefferson et al., 2007). Items have been rank ordered in terms of their ability to be named, which is thought to be correlated with their frequency.
The assessment takes approximately 10 minutes.
Other Important Notes
Spanish versions of the BNT are available (Peña-Casanova et al., 2009; Ponton et al., 1996).
Comments/Special Instructions
Scoring and Psychometric Properties
Patients have 20 seconds to respond to each item. Each item is scored as correct, correct with semantic cues, or correct with phonemic cues. The total score is the number correct spontaneously or with semantic cues.
Psychometric Properties
Interjudge and intrajudge reliability were found to be high, average of 89.1% and 97.6% respectively. Overall reliability using a matrix agreement system adjusting for chance was 91.2% (Nicholas et al., 1998).
