The present research employed a longitudinal design to assess the verbal and non-verbal communicative abilities of a sample of 104 children, using two different parent-report instruments: the Questionnaire for Communication and Early Language (QCEL) development at 12, 16, and 20 months, and the Italian adaptation of the MacArthur-Bates Communicative Development Inventories: Words and Gestures at 23 months. The results supported and extended previous data about the validity of the QCEL, by showing that: (1) both verbal and non-verbal variables predicted the level of language development at 23 months; (2) children classified as at-risk with the QCEL had reduced vocabulary size and a lower number of sentences at 23 months; (3) early individual differences in the use of words and gestures were associated with later differences in linguistic abilities. It is concluded that the longitudinal use of the QCEL questionnaire can provide useful information about language development.
本研究采用纵向设计，使用两种不同的父母报告工具评估了 104 名儿童的言语和非言语交际能力：12、16 和 20 个月时的沟通和早期语言问卷（QCEL）发展，以及 23 个月时的麦克阿瑟 - 贝茨交际发展量表：单词和手势的意大利语改编版。研究结果支持并扩展了先前关于 QCEL 有效性的研究数据，表明：（1）言语和非言语变量均能预测 23 个月时的语言发展水平；（2）使用 QCEL 被分类为高风险的儿童在 23 个月时词汇量较小，句子数量也较少；（3）早期在使用单词和手势方面的个体差异与后期语言能力的差异有关。结论认为，纵向使用 QCEL 问卷可以提供有关语言发展的有用信息。
