Instrument to evaluate the perception of minimal contrasts in Chilean Sign Language - reliability evidence.
Carlos González Herrera, Themis Maria Kessler, Karina Carlesso Pagliarin
PMID 38055413WHAT IT FOUND
A Chilean Sign Language test gave results that stayed consistent when repeated 11 to 14 days later in 10 deaf children and adolescents, and two evaluators scored the same answers almost identically.
It shows consistency, not that the test identifies language disorder.
Key findings
01The first and second test scores were strongly related, and children scored better on the retest.
02Different evaluators agreed almost perfectly when scoring the recorded responses.

What it does not show
The sample was only 10 deaf children and adolescents, recruited by convenience sampling, and the authors recommend larger samples. The study tested only reliability; construct validity, criterion validity, sensitivity, and specificity were not tested. Children scored better on the retest, and the authors suggest this could reflect learning or memory because the interval was only 11 to 14 days. The authors state the small sample was partly because of COVID-19 pandemic conditions in Chile.

The easy way to misread this
Do not treat this as evidence that the test can diagnose language disorder. It only shows score consistency and evaluator agreement in 10 deaf children and adolescents, and the authors say validity, sensitivity, and specificity still need study.
