Identifying children with developmental disabilities is critical in providing early intervention services. This study aimed to evaluate the concurrent validity information of the 24-, 30-, and 36-month Indonesian Ages and Stages Questionnaires third edition (ASQ-3) with Bayley Scales of Infant and Toddler Development 3rd Edition (BSID-III) in Indonesian children. Children living in Tanah Tinggi subdistrict, Central Jakarta, within the 24-, 30-, or 36-month age group, were assessed for Indonesian ASQ-3 concurrently with BSID-III. Screening test accuracy was measured in sensitivity, specificity, and predictive values for both overall dan specific domains. A total of 131 children were included as study participants. Sensitivity, specificity, positive predictive value, and negative predictive value (NPV) for 24-, 30-, and 36- month ASQ-3 questionnaires were 80.6%, 69.5%, 50%, and 90.4%, respectively. Age-specific sensitivity and specificity were 72.7%–84.6% and 59.4%–79.4%, with accuracy increasing from 65.9% at 24-month to 77.8% at 36-month. The accuracy in detecting language delay (88.5%) is higher than cognitive delay (77.9%) and motor delay (64.1%). ASQ-3 overall and age-specific sensitivities were good enough, given they were above 70%. The 36-month questionnaire had the best accuracy. A high NPV supports using the ASQ-3 Indonesian version to exclude developmental delay.

印度尼西亚版年龄和阶段问卷 III 的准确性与 Bayley 婴儿发育量表 III 的比较

识别有发育障碍的儿童对于提供早期干预服务至关重要。本研究旨在评估 24、30 和 36 个月印度尼西亚年龄和阶段问卷第三版 (ASQ-3) 与 Bayley 婴幼儿发展量表第三版 (BSID-III) 在印度尼西亚语中的同时有效性信息孩子们。居住在雅加达中部 Tanah Tinggi 分区的 24、30 或 36 个月年龄组的儿童同时接受了印度尼西亚 ASQ-3 和 BSID-III 评估。筛选测试的准确性是通过灵敏度、特异性和预测值来衡量的，这两个领域都是整体和特定领域。共有 131 名儿童被纳入研究参与者。24-、30-、和 36 个月的 ASQ-3 问卷分别为 80.6%、69.5%、50% 和 90.4%。年龄特异性敏感性和特异性分别为 72.7%–84.6% 和 59.4%–79.4%，准确度从 24 个月时的 65.9% 增加到 36 个月时的 77.8%。检测语言延迟的准确率（88.5%）高于认知延迟（77.9%）和运动延迟（64.1%）。ASQ-3 的总体和特定年龄敏感性已经足够好，超过 70%。36 个月问卷的准确性最高。高 NPV 支持使用 ASQ-3 印度尼西亚语版本排除发育迟缓。9%) 和运动延迟 (64.1%)。ASQ-3 的总体和特定年龄敏感性已经足够好，超过 70%。36 个月问卷的准确性最高。高 NPV 支持使用 ASQ-3 印度尼西亚语版本排除发育迟缓。9%) 和运动延迟 (64.1%)。ASQ-3 的总体和特定年龄敏感性已经足够好，超过 70%。36 个月问卷的准确性最高。高 NPV 支持使用 ASQ-3 印度尼西亚语版本排除发育迟缓。
