Naming Test of the Neuropsychological Assessment Battery: reliability and validity in a sample of patients with acquired brain injury.

The current study assessed the internal consistency, alternate forms reliability, and convergent/divergent validity of the Naming Test of the Neuropsychological Assessment Battery (NAB) in patients with acquired brain injury. Fifty-nine patients were administered the NAB Naming Test (forms 1 and 2) and the Boston Naming Test (BNT), as well as other tests of neuropsychological functioning. Forms 1 and 2 of the NAB Naming Test demonstrated adequate internal consistency and alternate forms reliability. The NAB Naming Test was significantly associated with scores from the BNT, as well as scores from tests that assess visuospatial skills, semantic fluency, and verbal memory. The divergent validity of the NAB Naming Test was demonstrated by non-significant associations with tests of attention and processing speed. BNT scores correlated significantly with the educational level and estimated premorbid intelligence but not age, whereas the NAB Naming Test scores only correlated significantly with estimated premorbid intelligence. The current study provides independent validation supporting the utility of the NAB Naming Test for patients with acquired brain injury.
