Abstract:
The use of standardized tests specifically designed for and normed on bilingual groups is crucial for the accurate diagnosis and language profiling of bilingual speakers with aphasia. Aims: (1) To revise the original screening KE-BAT to clarify ambiguities in its instructions and stimuli; and (2) to examine subtest and item performance across the two languages. Total and subtest scores were compared across the two languages, and individual item accuracy was calculated. Performance was comparable across Korean and English for all subtests, except for the spontaneous speech subtest. Incorrect responses of low scoring items were caused by phoneme misperception, lexical substitution and morphosyntactic L2 patterns. The results of the study highlight the importance of empirically examining the performance of neurotypical bilinguals on bilingual aphasia assessments to establish their psychometric properties.
