SUMMARY:

Children with restricted vocabulary are at risk for language disorders, and may present delays at morphosyntatic level, difficulties in decoding and reading comprehension. Identifying this signs contribute to early intervention and, therefore, a better prognosis. TRILHAR is an instrument developed by brazilian researchers and aims screening the receptive and expressive vocabulary of children between 3 and 7 years old. This study aims to contribute to the TRILHAR validation process by verifying the performance difference in students from different regions and by verifying the reliability and convergent validity of the instrument. For the first analysis, there are 255 children between 3 to 7 divided intro two groups: G1 – 122 children from the state of São Paulo and G2 – 133 children from the state of Rio Grande do Norte. All students, from G1 and G2, studies in brazilian public schools. Children in G1 had an average of 9.90 (SD = 0.350) points in receptive vocabulary, while those in G2 had 9.83 (SD = 0.412) points. As for expressive vocabulary, children in G1 had an average of 8.82 (SD = 1.305) and those in G2 8.53 (SD = 1.253) points. To compare performances, the t-test was used, demonstrating a p-value of 0.16 for receptive vocabulary and 0.07 for expressive vocabulary. This result demonstrates that there was no significant difference in performance between the two groups. The semantic aspect can be influenced by the family and school environment, age, parent’s education and sociocultural diversity. Therefore, when developing Brazilian vocabulary measurement and tracking tools, the sociolinguistic reality must be observed. The target words must consider the diversity of vocabulary in a geographically extensive country like Brazil. It is concluded that TRILHAR is suitable for application in these two different sociocultural contexts. Furthermore, it was possible to observe the average score obtained by both populations. This analysis may contribute to the process of establishing expected reference values for each age group. The second analysis, of convergent validity and reliability of the instrument, is in the process of being constructed.
