PMID 41017131WHAT IT FOUND
Monolingual sentence tests can separate bilingual children with and without language disorder, but accuracy depends heavily on how much Finnish the child has heard.
The Sentence Comprehension Test worked best with over 40% exposure, while the RDLS III worked best with less.
Key findings
01Children with typical development scored significantly higher than those with DLD on both sentence comprehension tests, with group status being the strongest predictor of performance.
02Lifetime exposure to the second language had a small effect on comprehension scores, and this effect did not differ between the two groups.
03Diagnostic accuracy varied by exposure level: the Sentence Comprehension Test classified children better with more than 40% exposure, while the RDLS III was more accurate with 15-25% exposure.

What it does not show
The study did not assess the children's first languages, so it could not determine if cross-linguistic influence affected comprehension. The sample size was too small to analyse the impact of specific first language backgrounds (e.g., Russian vs. Arabic). The tests were offline picture-selection tasks, which may not fully capture a child's ability to process specific grammatical structures in real-time. The groups differed in maternal education, with the typical development group having higher levels, which could confound the results.

The easy way to misread this
Do not assume that a child's poor score on a standardised test proves they have a language disorder. If the child has limited exposure to the test language, the test may not be accurate for them, and the low score could simply reflect unfamiliarity rather than impairment.
