PMID 38324878WHAT IT FOUND
The PEEPS-BP Expanded List now contains 29 stimulus words for assessing vocabulary and phonology in Brazilian Portuguese children aged 24 to 36 months.
Experts and mothers selected words familiar to this age group, and children confirmed the corresponding toys were recognizable.
Key findings
01The final PEEPS-BP Expanded List comprises 29 stimulus words validated for children aged 24 to 36 months.
02Content validity was established through four steps involving expert judges, non-expert judges (mothers), child judges, and a pilot study.
03Words were selected based on high agreement between experts and mothers regarding familiarity and whether the word could be represented by a toy.

What it does not show
The study validates content only; it does not provide normative data or criteria for clinical diagnosis. The sample sizes for child judges (4) and the pilot study (6) were very small and selected for convenience. The final list of 29 words is shorter than the original PEEPS-US Expanded List (over 20 words) and may have limited sensitivity for detecting subtle phonological deficits. The study was conducted in Brazil, so its applicability to other Portuguese-speaking populations or contexts may require further validation.

The easy way to misread this
Do not use this instrument for standardised scoring or diagnosis. It has only undergone content validation, meaning experts agreed the words are relevant. It lacks normative data, so you cannot determine if a child's score is typical or atypical compared to peers.
