Outline of Final Research Achievements

Stuttering that co-occurs with learning disabilities (LD), attention-deficit hyperactivity disorder (ADHD), and autism spectrum disorder (ASD) is often observed in educational and clinical settings. The current study aimed to estimate the rate of co-occurring LD, ADHD, and ASD for children who stutter (CWS) and clarify the characteristics of their learning and behavior difficulties in school. We conducted a questionnaire to screen for LD, ADHD, and ASD in CWS enrolled in resource rooms for speech-language disorders. Results: Thirty-five of 335 (≧10.5%) children were assessed as presenting difficulties in learning and/or behavior in school life and suspected of having LD, ADHD, and ADHD, and this rate appeared to be higher than that in children enrolled in regular classes in Japan (6.5%). Further development of the questionnaire might be needed to increase the reliability of the results of this survey.

Academic Significance and Societal Importance of the Research Achievements

これまでに，国内で，吃音のある者に含まれる発達障害との合併の割合について明らかにされた研究はなかった。本研究では，文部科学省（2012）の調査を参考に，吃音のある児童を対象に発達障害を重複する児童の割合を推定することができたことに学術的意義がある。さらに，ことばの教室では，吃音のみに注目するのではなく，重複する問題について視野に入れて教育を行うことが望まれることを明らかにした点で社会的意義がある。
