RESUMO
BACKGROUND: Due to demographic changes over the last few decades, the number of multilingual children has grown rapidly. Many of them face problems in learning their second language. Similarities between linguistic manifestations of stages of second language acquisition and an impairment of language acquisition cause a diagnostic dilemma. The Vienna Model of language assessment in multilingual children will be presented. METHODS: A key feature of our procedure is the integration of medical students as native speakers in diagnosing acquisition of the first language. A case study of a boy with Russian as first language illustrates the procedure. RESULTS: The Vienna Model of language assessment in multilingual children offers the possibility to evaluate language competence in a differentiated manner with support of medical students as native speakers. Based on the bilingual assessment on different linguistic levels the diagnosis ICD-10 F80.0 is given. The subsequent short therapy showed an improvement regarding phonological competence.
