A brief Spanish-English equivalent version of the Boston Naming Test: a Project FRONTIER study

The Boston Naming Test is a neuropsychological measure of confrontation naming, short forms of which can be advantageous with various populations. The purpose of this study was to establish a Spanish-English equivalent version of the BNT using item response theory. Data were analyzed from 380 Project FRONTIER participants; 27 items differed between groups and were removed from the measure. Additionally, 18 items did not differ between groups but were poor items. The current 15-item Spanish-English equivalent version of the BNT offers significant advantages. Future work is required to validate the diagnostic utility of the instrument in various settings and populations.
