Naturalistic-developmental-behavioral interventions (NDBIs) are a widely accepted and validated approach for treating language-related symptoms in autism spectrum disorder, including deficits in vocabulary, social skills, and grammar. The purpose of this article is to define the elements , , and as applied to children with developmental language disorder (DLD) and to provide an example of how this type of intervention can be implemented to teach vocabulary and test cross-modal generalization between expressive and receptive modalities.
A vocabulary intervention using hybrid NDBI methods (storybook reading and conversational recast interaction) was provided to three participants with DLD using a single-case design.
The results indicated that all participants successfully learned receptive and expressive vocabulary targets with extensive cross-modal generalization. However, generalization was limited in some of the participants.
This article provided definitions of key elements of NDBI (, , and ) including a rationale for extending NDBI procedures to language intervention for children with DLD. In addition, a single-case design demonstrated that NDBI can be implemented in DLD and that broadly defined naturalistic-developmental applied behavior analysis techniques are applicable to language interventions for children with language disorders. Moreover, diverse and procedures meet the highest standards for evidence-based practice to treat DLD.
自然主义-发展-行为干预（NDBI）是一种广泛接受和验证的方法，用于治疗自闭症谱系障碍中的语言相关症状，包括词汇、社交技能和语法缺陷。本文的目的是定义应用于发育性语言障碍（DLD）儿童的元素 、 和 ，并提供一个示例，说明如何实施这种干预类型来教授词汇，并测试表达和接受模态之间的跨模态泛化。
使用混合 NDBI 方法（故事书阅读和对话重铸互动）对三名 DLD 参与者进行词汇干预，采用单一案例设计。
结果表明，所有参与者都成功地学习了接受和表达词汇目标，并进行了广泛的跨模态泛化。然而，一些参与者的泛化是有限的。
本文提供了 NDBI 的关键元素（ 、 和 ）的定义，包括将 NDBI 程序扩展到 DLD 儿童语言干预的基本原理。此外，单一案例设计表明，NDBI 可以在 DLD 中实施，并且广泛定义的自然主义-发展应用行为分析技术适用于语言障碍儿童的语言干预。此外，多样化的 和 程序符合治疗 DLD 的循证实践的最高标准。
