Purpose The purpose of this study was to determine if a standardized assessment developed for Spanish-English dual language learners (SEDLLs) differentiates SEDLLs with language impairment (LI) from children with typical language better than the translated/adapted Spanish and/or English version of a standardized assessment and to determine if adding informal measure/s to the standardized assessment increases the classification accuracy. Method Standardized and informal language assessment measures were administered to 30 Mexican American 4- to 5-year-old SEDLLs to determine the predictive value of each measure and the group of measures that best identified children with LI and typical language. Discriminant analyses were performed on the data set. Results The Morphosyntax and Semantics subtests of the Bilingual English-Spanish Assessment ( Peña, Gutierrez-Clellen, Iglesias, Golstein, & Bedore, 2014 ) resulted in the largest effect size of the individual assessments with a sensitivity of 93.3% and a specificity of 86.7%. Combining these subtests with mean length of utterance in words from the child's better language sample (English or Spanish) was most accurate in identifying LI and can be used with above 90% confidence. Conclusion The Bilingual English-Spanish Assessment Morphosyntax and Semantics subtests were shown to comprise an effective measure for identifying LI; however, including a language sample is suggested to identify LI with greater accuracy.
目的 本研究旨在确定为西班牙语-英语双语学习者(SEDLL)开发的标准化评估是否比标准化评估的翻译/改编的西班牙语和/或英语版本更能区分有语言障碍(LI)的 SEDLL 与具有典型语言的儿童,以及是否添加非正规措施到标准化评估会提高分类准确性。 方法 对 30 名墨西哥裔美国 4-5 岁 SEDLL 进行了标准化和非语言评估,以确定每个评估和最佳识别有 LI 和典型语言的儿童的评估组的预测值。对数据集进行了判别分析。 结果 Bilingual English-Spanish Assessment(Peña、Gutierrez-Clellen、Iglesias、Golstein 和 Bedore,2014)的 Morphosyntax 和 Semantics 子测试是个体评估中效果最大的,敏感性为 93.3%,特异性为 86.7%。将这些子测试与儿童较好语言样本(英语或西班牙语)中的单词平均话语长度结合使用,可以更准确地识别 LI,准确率超过 90%。 结论 Bilingual English-Spanish Assessment 的 Morphosyntax 和 Semantics 子测试被证明是识别 LI 的有效措施;然而,建议包括语言样本以更准确地识别 LI。
