The BNT-38: Applying Rasch Analysis to Adapt the Boston Naming Test for Use With English and French Monolinguals and Bilinguals

摘要

Purpose: Currently, there is no reliable instrument to measure naming abilities in bilingual speakers of English and French. The Boston Naming Test (BNT; Kaplan, Goodglass, & Weintraub, 1983) is a widely used scale for clinical assessments of language function, but it is not suitable to assess bilinguals. Rasch analysis provides a unique and powerful method to establish measurement invariance across language groups that improves reliability of measurement.
