Résumé
Developmental Language Disorder (DLD), which affects both monolingual and bilingual individuals, is a lifelong condition, impacting not only on learning but also on peer relationships and mental health. In the last census, one in four families in France spoke another language than French. DLD is still difficult to diagnose in bilinguals though, due to the lack of calibration in French language tests on this population and the rare possibility of assessment in another language by the therapist. Also, difficulties are likely to be less well assessed by the family and carers, making access to care later and sometimes only in adolescence. Thus, we wished to observe whether tests from the EVALEO 6-15 battery were sensitive to DLD in bilingual adolescents aged 12 to 15 years. We recruited 5 typically developing bilingual adolescents and 5 bilingual adolescents with a diagnosis of DLD, to whom we administered the PaBiQ and 9 cognitive and oral language tasks. In order to distinguish between the two groups, some tests showed encouraging results, notably in sentence closure and non-word repetition. However, the small size of our sample and the few significant results do not allow us to draw definitive conclusions about the use of this battery for the detection of DLD in bilingual adolescents. Further research or separate calibration on a larger scale seems essential to provide a relevant language assessment for bilingual adolescents, a population that has not yet been extensively studied.
