Evidências de validade de conteúdo de um instrumento de triagem do vocabulário

Abstract

OBJETIVOS: to verify the evidences based on content validity of a vocabulary screening instrument for children aged from 3 to 7 years old. MÉTODOS: This study was divided into three steps: 1º) Integrative literature review on nacional and international database Scielo, Lilacs, Eric and Pubmed, to verify the vocabulary screening instruments used recently (Article 1); 2º) Content analysis: the instrument was sent to fifteen judges, who analyzed the content validity based on the criterias of Theory, Screening Principles and Materials, considering the Content Validity Index (CVI) and Content Validity Index Item (Article 2); 3º) Aplicability of the instrument: screening of 133 children from 3 to 7 years old, students of four public schools (Article 3). RESULTADOS: from the theorical review, it was possible to construct the receptive and expressive vocabulary screening instrument, named TRILHAR. On the content validity analysis, the CVI has proven itself adequate. However, the CVI-I for the subcriterias of graphic aspects and description of the application sheet was inadequate, indicading the necessity of revision for those items. On the pilot study, there was differences on the performance between the groups and correlation between these variables, showing that the result on the screening improves according to the advencement of age. Besides that, there was a positive correlation between receptive and expressive vocabulary. CONCLUSÃO: the results of this research showed that TRILHAR is an adequate instrument for infant vocabulary screening. However, more validity studies are necessary to verify it's capability to identify children with vocabulary delays.
