PMID 37878836WHAT IT FOUND
Most words in this speech test were easy for children to name spontaneously, but seven items caused confusion or required heavy prompting.
Experts agreed the test content is suitable for assessing children's speech, though some words need changing.
Key findings
01Expert judges agreed that the words and images used in the assessment are suitable for evaluating children's speech.
02Seven specific words were identified as problematic by judges or difficult for children to name without significant help.
03The test items worked together consistently to measure the intended speech skills.

What it does not show
The study only checked content validity and how children responded to the test items. It did not yet prove the test measures what it claims to measure (construct validity) or that it gives the same results over time (reliability). The sample was limited to children from a single public school in Porto Alegre, which may not represent all Brazilian children. Three children did not complete the full test, which could slightly affect the results.

The easy way to misread this
Do not assume this test is fully validated for all diagnostic uses. It has only been checked for content suitability and child response patterns, not for its ability to accurately diagnose phonological disorders compared to a gold standard.
