To examine the validity of the MacArthur-Bates Communicative Development Inventories (CDI) for measuring language abilities in children with profound hearing loss who are using cochlear implants.
Twenty-four children with cochlear implants and their mothers participated in this study. Children ranged in age from 32 months to 86 months (the majority were 32 to 66 months old). The number of months postimplantation ranged from 3 to 60 (the majority were around 24 months). Mothers completed the CDI before behavioral testing. Behavioral measures included the Reynell Developmental Language Scales and measures of vocabulary and grammar from a spontaneous language sample.
Both the Words and Gestures and the Words and Sentences forms of the CDI were shown to have excellent validity for this sample of children, if they had language that was in the range measured by the instrument. Correlations with behavioral measures ranged from .41 to .93 and were comparable to those reported for children with typical development.
The CDI forms are valid tools to use with children who are using cochlear implants and who are in the early stages of language development, even if they are older than the norming sample. Age-equivalence may be obtained if children score below the median for the oldest age norms. They may also be used to describe the language of children who are not at ceiling. Specific recommendations for interventionists are provided.
检验麦克阿瑟-贝茨交流发展量表（CDI）在测量使用人工耳蜗的重度听力损失儿童语言能力方面的有效性。
24名使用人工耳蜗的儿童及其母亲参与了本研究。儿童年龄在32个月至86个月之间（大多数为32至66个月大）。植入后时间从3个月至60个月不等（大多数约为24个月）。母亲们在行为测试前完成CDI。行为测量包括雷内尔发育语言量表以及来自自发语言样本的词汇和语法测量。
如果这些儿童的语言处于该工具所测量的范围内，CDI的单词与手势形式和单词与句子形式对该样本儿童均显示出极佳的有效性。与行为测量的相关性在0.41至0.93之间，与报道的正常发育儿童的相关性相当。
CDI形式是适用于使用人工耳蜗且处于语言发展早期阶段儿童的有效工具，即使他们年龄大于常模样本。如果儿童得分低于最年长年龄常模的中位数，可能会获得年龄等效性。它们也可用于描述未达到上限的儿童的语言情况。为干预者提供了具体建议。
