The purpose of the current study was to examine the concurrent validity and classification accuracy of 3 parent report measures of language development in Spanish-speaking toddlers.
Forty-five Spanish-speaking parents and their 2-year-old children participated. Twenty-three children had expressive language delays (ELDs) as determined through multiple sources of information, and 22 had typical language development (TD). Parents completed the Spanish version of the Ages and Stages Questionnaire (Spanish ASQ; Squires, Potter, & Bricker, 1999) and the short-form of the Inventarios del Desarrollo de Habilidades Comunicativas Palabras y Enunciados (INV-II; Jackson-Maldonado, Bates, & Thal, 1992; Jackson-Maldonado et al., 2003), which is the Spanish version of the MacArthur-Bates Communicative Development Inventories Words and Sentences form, and reported children's 3 longest utterances (M3L-W). Children were administered the Preschool Language Scale, Fourth Edition, Spanish Edition (SPLS-4; Zimmerman, Steiner, & Pond, 2002) at early childhood centers.
All 3 parent report measures were significantly correlated with the SPLS-4, establishing their concurrent validity. Children with ELDs scored significantly lower than TD children on all 3 parent report measures. The Spanish ASQ demonstrated less than desirable levels of sensitivity and specificity; both the short-form INV-II and M3L-W measures demonstrated favorable sensitivity and specificity. Of these measures, M3L-W demonstrated the strongest classification accuracy qualities, including sensitivity, negative predictive value, and area under the receiver operating characteristics curve.
The short-form INV-II and M3L-W demonstrated highly satisfactory classification accuracy of ELDs, but M3L-W demonstrated slightly stronger accuracy. These results indicate that these measures may be useful in screening for ELDs in Spanish-speaking toddlers.
本研究旨在检验 3 种家长报告的西班牙语幼儿语言发展评估工具的同时效度和分类准确性。
共有 45 名西班牙语家长及其 2 岁儿童参与了研究。23 名儿童被确定为表达性语言延迟（ELD），22 名儿童具有典型的语言发展（TD）。家长完成了西班牙语版年龄与阶段问卷（Spanish ASQ；Squires、Potter 和 Bricker，1999）和简短版沟通技能发展词汇和句子问卷（INV-II；Jackson-Maldonado、Bates 和 Thal，1992；Jackson-Maldonado 等人，2003），这是麦克阿瑟-贝茨沟通发展词汇和句子量表的西班牙语版，以及报告儿童的 3 个最长话语（M3L-W）。儿童在幼儿中心接受了第四版学前语言量表，西班牙语版（SPLS-4；Zimmerman、Steiner 和 Pond，2002）的测试。
所有 3 种家长报告评估工具与 SPLS-4 均呈显著相关，证明了其同时效度。有 ELD 的儿童在所有 3 种家长报告评估工具上的得分均显著低于 TD 儿童。西班牙语 ASQ 的灵敏度和特异性均不理想；简短版 INV-II 和 M3L-W 均表现出良好的灵敏度和特异性。在这些评估工具中，M3L-W 表现出最强的分类准确性，包括灵敏度、阴性预测值和受试者工作特征曲线下的面积。
简短版 INV-II 和 M3L-W 对 ELD 的分类准确性非常高，但 M3L-W 的准确性略高。这些结果表明，这些评估工具可能有助于对西班牙语幼儿进行 ELD 的筛查。
