Outline of Final Research Achievements

This study aimed to develop a home-based comprehensive language development intervention to clarify the process of language acquisition by children with autism spectrum disorder (ASD). In the first year, we examined intervention strategies to facilitate production of words and phrases/sentences from vocalizations for children with ASD. In the next and final year, the intervention strategies which we developed were tested to investigate if they could be applied by parents at home. Consequently, it was revealed that adults responding to the speech of children with ASD, with the same speech and extended speech (contingent imitation and extended contingent imitation) is an effective intervention strategy for promoting speech from utterances to words and from words to phrases and sentences. Furthermore, the intervention strategies were found to be procedures that could be applied by parents at home.

Academic Significance and Societal Importance of the Research Achievements

自閉スペクトラム症(ASD)児に対する家庭密着型の包括的言語発達支援の開発と評価を行った。本研究は、ASD児の発声から語、語から 句・文の発話へと段階的な言語の獲得と社会的相互作用場面での使用への拡張を含めた包括的な言語の獲得・拡張を促す環境条件を明らかにした点に学術的意義がある。さらに本研究は、家庭という生活基盤の中で、ASD児の中核症状となる言語の発達に焦点を当て、保護者が家庭で適用可能な支援システムを構築した点に社会的意義がある。本研究により得られた成果は、多くのASD児が個々の言語発達段階に応じた支援を受けることができる環境を整備するために活かすことができる。
