Abstract

The current lack of assessment materials for Spanish/English adults with bilingual aphasia often leads clinicians and researchers to use culturally and psychometrically inappropriate materials. In this study, ninety Spanish/English bilingual adults with varying proficiencies were administered An Object and Action Naming Battery. Item analyses using classical item analysis and item response theory revealed a large number of nouns and verbs able to discriminate proficiency levels in English and Spanish. A regression analysis revealed an emerging model of participant factors that predict naming performance, with Spanish yielding a higher correlation coefficient with more predictive factors than English.
