To adapt the "Language Use Inventory" parent -report measure for Brazilian Portuguese children.
A total of 254 Brazilian parents and children participated in the survey, comprising five groups within an age range from 18 to 47 months. The translated and pre-adapted version of the Language Use Inventory (LUI) measure into Brazilian Portuguese was used in online and in person format. Analysis of Cronbach's alpha coefficients was used to verify the internal reliability, and Kruskal-Wallis and Mann-Whitney tests were used to analyze the form of completion, sex, child's age group, and parents' education level.
Comparative analyses between the completion methods did not identify significant differences between the printed and online formats. The Brazilian Portuguese version of the LUI demonstrated high internal consistency with respect to all subscales and with respect to the entire measure (α>0.99). Girls obtained higher scores than boys for Part 2 (p<0.001) and Part 3 (p=0.001) and on the Total LUI score (p=0.001). Children whose parents had more years of schooling obtained higher scores in Parts 2 and 3.
The similarity of results related to internal reliability and developmental trends of the Brazilian Portuguese version of LUI as compared with the original English version, supports its use as a reliable instrument to assess pragmatic language functioning in Brazilian preschoolers.
对巴西葡萄牙语儿童改编“语言使用量表”家长报告测量工具。
共有254名巴西家长和儿童参与了调查，包括年龄在18至47个月之间的五个组。以在线和面对面形式使用了翻译成巴西葡萄牙语并预先改编的语言使用量表（LUI）测量工具。使用克朗巴哈α系数分析来验证内部信度，使用克鲁斯卡尔 - 沃利斯检验和曼 - 惠特尼检验来分析完成形式、性别、儿童年龄组和家长教育水平。
完成方式之间的比较分析未发现印刷版和在线版之间存在显著差异。巴西葡萄牙语版的LUI在所有子量表以及整个测量工具方面都表现出高度的内部一致性（α>0.99）。女孩在第2部分（p<0.001）、第3部分（p = 0.001）以及LUI总分（p = 0.001）上的得分高于男孩。父母受教育年限较长的儿童在第2部分和第3部分得分更高。
与原始英语版本相比，巴西葡萄牙语版LUI在内部信度和发展趋势方面结果相似，支持将其用作评估巴西学龄前儿童语用语言功能的可靠工具。
