Arengulist keelepuuet esineb võrdselt üks- ja kakskeelsete laste seas. Kakskeelsetel on aga suurem valediagnoosi risk, kuna kakskeelsete laste veatüübid mittedominantses keeles sarnanevad ükskeelsete keelepuudega laste veatüüpidele. See risk on aktuaalne paljude vene kodukeelega suktsessiivsete kakskeelsete laste jaoks, kes käivad eestikeelses lasteaias. Et toetada keelepuude diagnoosimist, on vaja kakskeelsel valimil normitud teste. Artiklis kirjeldame taolise eestikeelse sõnavaratesti koostamist 4–7-aastastele lastele. Test on välja töötatud rahvusvahelise LITMUS võrgustiku sõnavaratesti põhimõtete ja protokolli alusel. Materjali väljavalimiseks viisime läbi kolm eeluuringut täiskasvanud kõnelejatega ning kaks prooviuuringut lastega. Anname ülevaate ka 2024. aastal läbiviidud normimisuuringu I etapi tulemustest. Tulemuste põhjal võib järeldada, et test on jõukohane nii üks- kui kakskeelsetele lastele, eristab mõlemas rühmas keelepuudega lapsi eakohase arenguga lastest ning sobib koos teiste LITMUS testikomplekti testidega kasutamiseks keelepuude diagnoosimisel ja laste keeleliste oskuste kirjeldamisel.

"Developing Estonian Cross-Linguistic Lexical Tasks for identifying DLD in bilingual children"

Developmental language disorder (DLD) is as prevalent among bilingual as among monolingual children (Calder et al. 2022). However, bilinguals face a greater risk of misdiagnosis, as the error types of typically developing bilinguals in their non-dominant language often resemble those of monolingual children with DLD (Boerma, Blom 2017). With the transition to all-Estonian instruction in Estonian education scheduled for 2024–2030, many more successive Russian-Estonian bilinguals face this risk. Language tests developed for and normed on bilingual populations are necessary for more reliable diagnosis of DLD among bilinguals. In this paper, we describe developing such a vocabulary test for children aged 4–7: the Estonian Cross-Linguistic Lexical Tasks (Haman et al. 2015). The test is designed according to cross-linguistic principles set out by the international working group. To select stimuli for the Estonian test, we conducted three preliminary studies with adult speakers: a picture naming task, subjective age of acquisition survey and a complexity evaluation. To test the material’s suitability for children, two pilot studies with mono- and bilingual children were conducted. Stimuli that contributed less to distinguishing DLD and typically developing children were changed (Labent 2023), and the revised test was then used in a norming study. First results of the norming study indicate the test is suitable for use both with monolingual and bilingual children and distinguishes DLD children from typically developing peers in both groups. A correlation analysis with results from the LITMUS Sentence Repetition Task reveals moderate to strong significant correlations between the two test scores, suggesting the tests complement each other well in describing bilingual children’s language skills and diagnosing DLD.
