A multicentric cross-sectional collaborative study was undertaken in 3 centres in India with the main aim of developing simple and reliable indicators for the early detection of developmental disabilities in children under 6 years of age and to compare the age of attainment of developmental milestones in children in the three regions. The study provided a simple low-cost and culture-appropriate psychosocial developmental screening test battery which can be used with ease by trained public health grass-roots functionaries. This instrument was standardized on a large rural, tribal and urban sample comprising more than 13,000 children from 3 regions in India. The procedure for sampling, selection of items and methodology for standardization of the instrument in the Hyderabad region detailed in this paper were replicated in other centres as well. Quality control of data was ensured through inter-rater and test-retest measures of reliability. During pre-testing, 66 culture-appropriate milestones were selected finally from a larger item pool. The 50th centile age reference values of the Hyderabad study children and those obtained by other 2 centres were comparable.
在印度的3个中心开展了一项多中心横断面合作研究，其主要目的是制定简单可靠的指标，用于早期发现6岁以下儿童的发育障碍，并比较三个地区儿童达到发育里程碑的年龄。该研究提供了一种简单、低成本且适合当地文化的心理社会发育筛查测试组合，经过培训的公共卫生基层工作人员可以轻松使用。该工具在一个大型农村、部落和城市样本上进行了标准化，样本包括来自印度3个地区的13000多名儿童。本文详细介绍的海得拉巴地区仪器的抽样程序、项目选择和标准化方法也在其他中心进行了复制。通过评分者间和重测信度措施确保了数据的质量控制。在预测试期间，最终从更大的项目库中选择了66个适合当地文化的里程碑。海得拉巴研究儿童的第50百分位年龄参考值与其他两个中心获得的参考值具有可比性。
