Development of a Short Form of the Boston Naming Test for Individuals With Aphasia

Conclusions: The new short form demonstrates good psychometric properties when used with individuals with aphasia. However, the Mack et al. form proved to be as psychometrically sound as the BNT–Aphasia Short Form and is also appropriate for individuals with aphasia.

Age, gender, and education effects on vocabulary measures in Greek

Outcomes & Results: Education effects were generally stronger than age effects, and were strongest on the WASI. Age effects (independent of educational level) were highest for the BNT and lowest for the WASI Vocabulary. Relationships among tests and also between each vocabulary test and an index of non-verbal intelligence are also discussed.

Effects of demographic variables and health status on brief vocabulary measures in Greek

Outcomes & Results: Short forms consisted of 32 items for the PPVT-R, 15 items for WASI Vocabulary, and 20 items for BNT. Correlation coefficients between full and short forms ranged between .95 and .97. Total rate of inconsistent classification of persons with very low scores (lower than 2 SD below the population mean) based on the short forms was less than 3%, highlighting adequate potential sensitivity for clinical purposes. The equivalence of the two versions of each test was further attested by similar patterns of relationships with demographic variables. Indices of internal consistency and test-retest reliability were very good for each of the three tests. Finally, the sensitivity of the short forms of each test for detecting lexical/semantic deterioration as a function of systemic diseases is discussed.

Visual naming performance after ATL resection: Impact of atypical language dominance

Atypical language dominance is a predictor of change in visual naming performance after left ATL and may also impact postsurgical seizure control. This should be considered when counseling surgical candidates.
