The validity of the Fundación MacArthur Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC:PE) was examined with twenty 20- and nineteen 28-month-old, typically developing, monolingual, Spanish-speaking children living in Mexico. One measure of vocabulary (number of words) and two measures of grammar (mean of the three longest utterances and grammatical complexity score) from the IDHC:PE were compared to behavioral measures of vocabulary (number of different words from a language sample and number of objects named in a confrontation naming task) and one behavioral measure of grammar (mean length of utterance from a language sample). Only vocabulary measures were assessed in the 20-month-olds because of floor effects on the grammar measures. Results indicated validity for assessing expressive vocabulary in 20-month-olds and expressive vocabulary and grammar in 28-month-olds.
单词与语句（IDHC:PE）在20名20个月大以及19名28个月大的发育正常、单语、讲西班牙语且生活在墨西哥的儿童中进行了效度检验。将IDHC:PE中的一项词汇指标（单词数量）和两项语法指标（三个最长语句的均值和语法复杂度得分）与词汇的行为指标（语言样本中不同单词的数量以及在图片命名任务中命名物体的数量）以及一项语法行为指标（语言样本的平均语句长度）进行了比较。由于语法指标存在地板效应，仅对20个月大的儿童进行了词汇指标评估。结果表明，该量表在评估20个月大儿童的表达性词汇以及28个月大儿童的表达性词汇和语法方面具有效度。
