Considering the shortage of language intervention protocols which specifically concentrate on cochlear implanted children and considering the importance of timely language intervention in this group of children, the aim of the present study was to develop an interventional package on "receptive vocabulary" for cochlear implanted children.
MATERIALS & METHODS: By reviewing the literature related to language acquisition theories in normal and language disordered children, as well as literature on production of intervention protocols, especially those for language impaired children, and also considering the normal process of language and speech development in normal children, the first draft of the intervention protocol was prepared. Then, the face and content validity of the intervention protocol was assessed by a Delphi team through three rounds and finally approved.
A language intervention protocol was developed to enhance receptive vocabulary in 12-48 months-old cochlear implanted children, based on cognitive, behavioral and developmental theories. This protocol includes 5 interventional stages: 1-Drilling and Imitation; 2-Modeling; 3-Motor training; 4-Deliberate error correction; 5- Reinstatement and Generalization. Each stage consists of the description of the aims of that stage, a list of techniques, the tools required, the detailed step by step explanation of the intervention, how re-enforcement must take place, and finally the indicators of success which permit to move forward to the next stage.
The interventional package produced is believed to facilitate language acquisition in cochlear implanted children, according to expert qualitative assessment and approval. Experimental research is required for verification of this assumption.
鉴于专门针对人工耳蜗植入儿童的语言干预方案匮乏，且考虑到该群体及时进行语言干预的重要性，本研究旨在为人工耳蜗植入儿童制定一套关于“接受性词汇”的干预方案。
通过查阅与正常儿童和语言障碍儿童语言习得理论相关的文献，以及关于干预方案制定的文献，特别是针对语言障碍儿童的文献，并结合正常儿童语言和言语发展的正常过程，制定了干预方案初稿。然后，通过三轮德尔菲法由一个专家小组对干预方案的表面效度和内容效度进行评估，最终获得批准。
基于认知、行为和发展理论，制定了一项旨在提高12至48个月大人工耳蜗植入儿童接受性词汇的语言干预方案。该方案包括5个干预阶段：1. 操练与模仿；2. 示范；3. 运动训练；4. 刻意纠错；5. 强化与泛化。每个阶段都包括该阶段目标的描述、一系列技术、所需工具、干预的详细逐步说明、强化必须如何进行，以及最终允许进入下一阶段的成功指标。
根据专家的定性评估和批准，所制定的干预方案被认为有助于人工耳蜗植入儿童的语言习得。需要进行实验研究来验证这一假设。
