Language disorder (LD) is a neurodevelopmental disorder, and early diagnosis has an impact on speech therapy practice. The aim of this work is to test the usefulness of the Cognitive and Language scales of the Bayley-III in the early diagnosis of LD.
In a longitudinal study, a clinical sample of 187 children with diagnostic hypothesis of communication disorders at 4.5 years was assessed with the Bayley-III before age 3.5 years and subsequently with other scales of different psychological and psycholinguistic functions.
The results indicate that children with LD scored significantly lower than their control groups in all subtests and compounds of the Bayley-III. Additionally, low scores on the Language composite in the Bayley-III predicted lower scores in the Auditory-vocal Channel of the ITPA. A significant correlation was obtained between the Cognitive Scale of the Bayley-III and the General Cognitive Scale of the MSCA and the Mental Processing Composite of the K-ABC.
We can draw the conclusion that the Cognitive and Language scales of the Bayley-III are a useful instrument for early diagnosis of LD, and can also discriminate more severe forms of LD.
语言障碍（LD）是一种神经发育障碍，早期诊断对言语治疗实践有影响。本研究的目的是检验贝利婴幼儿发展量表第三版（Bayley-III）的认知和语言量表在LD早期诊断中的效用。
在一项纵向研究中，对187名4.5岁时被诊断为有沟通障碍假设的儿童临床样本，在3.5岁之前用贝利婴幼儿发展量表第三版进行评估，随后用其他不同心理和心理语言功能量表进行评估。
结果表明，LD儿童在贝利婴幼儿发展量表第三版的所有子测验和分量表中的得分均显著低于其对照组。此外，贝利婴幼儿发展量表第三版语言分量表得分低预示着伊利诺伊心理语言能力测验（ITPA）听觉-发声通道得分低。贝利婴幼儿发展量表第三版的认知量表与麦卡锡儿童能力量表（MSCA）的一般认知量表以及考夫曼儿童成套评估测验（K-ABC）的心理加工分量表之间存在显著相关性。
我们可以得出结论，贝利婴幼儿发展量表第三版的认知和语言量表是LD早期诊断的有用工具，并且还可以区分更严重形式的LD。
