Which Measures Better Discriminate Language Minority Bilingual Children With and Without Developmental Language Disorder? A Study Testing a Combined Protocol of First and Second Language Assessment.

Purpose This study aimed to assess a protocol for the evaluation of developmental language disorder (DLD) in language minority bilingual children (LMBC). The specific aims were (a) to test group differences, (b) to evaluate the discriminant validity of single measures included in the protocol, and (c) to define which model of combined variables had the best results in terms of efficacy and efficiency. Method Two groups of LMBC were involved, one with typical development ( = 35) selected from mainstream schools and one with DLD ( = 20).
