| Outline of Final Research Achievements |
Of the 2,482 infants who received the mandatory 18-month health examination, 116 infants showing the developmental risks were nominated to the cohort study about the early detection of Autism Spectrum Disorder (ASD). The 127 infants who lived in community were participated as the controls. All participants were performed the measurement of preferential looking at 2 years old. Their clinical outcome was diagnosed at 5 years old.
We found there were remarkable differences in the results of preferential looking between ASD without speech delay and non-ASD.
The differences were more remarkable between ASD without speech delay and controls. The sensitivity and specificity of ASD without speech delay to non ASD was 81.8 % and 76.1 % respectively, and also to controls was 81.8 % and 85.1 % respectively. As conclusion, the early detection using preferential looking examination succeeded.

| Academic Significance and Societal Importance of the Research Achievements |
1歳6か月児健診において言葉の遅れや視線の合いにくさ、多動などがある幼児を、2歳で選好性注視点検査を実施することにより、十分な感度と特異度で、言語発達に遅れのない自閉スぺクトラム症（ASD)のスクリーニングが可能であることが判明した。
これまで言語発達に遅れのないASDを乳幼児健診において発見することは困難であり、有効な手立てがなかった。本研究での方法を1歳6か月児健診に用いることにより、2歳という早期から療育を適切に提供できる。
言語発達に遅れのないASDは幼児期に気づかれることがなく就学し、学校生活を送る中で不適応が顕在化することが少なくない。これを未然に防止できる可能性がある。
