This study was conducted to verify the usefulness of the Brief Infant-Toddler Social and Emotional Assessment, a screening instrument for social and emotional behavioral problems in infants and young children, as an early screening tool for the characteristics of autism spectrum disorder in infants and young children. Reliability and validity tests were conducted on a total of 150 subjects: 50 in the ASD group and 100 in the general group. Measuring instruments used were the BITSEA ASD subscales (BITSEA-ASD problems and BITSEA-ASD competence), CARS, KM-CHAT, MSEL, K-ASQ, and CBCL. The result of the study show that in the BITSEA ASD subscale, the ASD group recorded a higher disparity in each domain compared to the general group. In the concurrent validity test, the correlations between CBCL1.5-5 and the BITSEA ASD subscales were .81 for the entire CBCL1.5-5 domain, .81 for the internalization domain, and .81 for externalization domain, showing a high correlation between them. The correlation between M-CHAT and the BITSEA-ASD subscale was .451, while the correlation between CARS and the BITSEA subscale was .587, showing a relatively good correlation. In summary, this study tested the possibility of using the BITSEA-ASD subscale as a screening instrument for early screening of ASD infants at a preliminary level.
