Dynamic dyadic parent-child interactions among CI-using children

项目总结 使用人工耳蜗(CI)的聋哑儿童的口语结果是非常不同的，有许多 使用顺式语言的儿童听力落后于听力正常的同龄人。在已确定的原因中， 可变性是父母的投入，有证据表明，父母投入的差异可能直接与 儿童CI后的语言结果。以家长为基础的语言干预，包括指导家长 他们的语言输入已经被提出作为改善父母输入的手段，从而提高 儿童的语言结果。然而，我们目前不知道父母的语言和责任感是如何 植入后随时间的变化，我们也不知道父母的语言如何影响孩子的语言 随着植入后时间的推移。缺乏对亲子动态关系的理解是一种 我们在创造有效的以家长为基础的干预措施以改善CI后语言结果的能力方面存在严重差距。 拟议的研究将通过识别动态和二元性来解决我们知识中的这一差距 认知障碍后父母语言输入与儿童语言发展的关系为了实现这一目标，我们 将对人工耳蜗术后儿童发育(CDaCI)进行二次分析 数据库，包括编码母语微结构、父母助语使用、母语 敏感，和儿童自发的表达语言。这些数据将使用二变量变化进行分析 分数模型，使我们能够确定父母投入和孩子之间的动态发展关系 语言。目标1将研究父母的语言、母亲的敏感和孩子的语言是如何变化的 时间到了。目标2将检验父母输入和儿童语言具有双向影响的假设。这个 获得的数据将提供初步证据，证明父母语言和儿童语言是相辅相成的。 这些数据将为R01应用程序开发和验证干预提供初步支持 针对父母的输入来支持语前聋儿童的语言发育，包括来自 历史上被边缘化的社区，推进我们优化语言和识字的长期目标 所有听力损失儿童的结果。

PROJECT SUMMARY Spoken language outcomes for deaf children who use cochlear implants (CIs) are highly variable, with many children who use CIs lagging behind their peers with normal hearing. Among the identified causes of this variability is parental input, with evidence suggesting that variation in parental input may directly relate to children's post-CI language outcomes. Parent-based language interventions, including coaching parents on their language input, have been proposed as a means of improving parental input and thereby improving children’s language outcomes. However, we currently do not know how parental language and responsivity change over time following implantation, nor do we know how parental language influences child language over time following implantation. This lack of understanding regarding parent-child dynamic relationships is a critical gap in our ability to create effective parent-based interventions to improve post-CI language outcomes. The proposed research will address this gap in our knowledge by identifying the dynamic and dyadic relationships between parental language input and child language development post-CI. To attain this goal, we will conduct a secondary analysis of the Childhood Development after Cochlear Implantation (CDaCI) database, including coding parent language microstructure, parental facilitative language use, maternal sensitivity, and child spontaneous expressive language. These data will be analyzed using bivariate change score models, allowing us to identify the dynamic developmental relations between parental input and child language. Aim 1 will examine how parental language, maternal sensitivity, and child language change over time. Aim 2 will test the hypothesis that parental input and child language have bidirectional influences. The obtained data will provide initial evidence that parental language and child language are mutually reinforcing. These data will provide preliminary support for an R01 application to develop and validate an intervention targeting parental input to support language growth in prelingually deafened children, including children from historically marginalized communities, advancing our long-term goal to optimize language and literacy outcomes for all children with hearing loss.
