The Ages & Stages Questionnaire 3rd Edition (ASQ-3) is a tool to measure developmental delay for children aged between 1 - 66 months originally developed in the United States. This measure has been collected in England since 2015 as a part of mandated 2-2½-year health visiting reviews and collated nationally in the Community Services Dataset (CSDS). CSDS is known to be incomplete and to-date there have not been any published analyses of ASQ-3 held within CSDS.
This study aimed to a) identify a subset of complete child development data for children aged two in England using ASQ-3 data in CSDS between 2018/19-2020/21; b) use this subset of data to analyse child development age 2-2½-years in England.
This study compared counts of ASQ-3 records in CSDS by local authority and financial quarter against national, publicly available Health Visitor Service Delivery Metrics (HVSDM) to identify local authorities with complete ASQ-3 records in CSDS. This study described child development in this subset of the data using both a binary cut-off of whether a child reached expected level of development and the continuous ASQ-3 score.
Among the 226,505 children from 64 local authorities in the sample with complete ASQ-3 data, 86.2% met expected level of development. Children from the most deprived neighbourhoods (82.6%), children recorded as Black (78.9%), and boys (81.7%) were less likely to meet expected level of development.
To fully understand early child development across England, the completeness of ASQ-3 data in the CSDS requires improvement. Second, in order to interpret the national CSDS data on child development, ASQ-3 should be standardised and validated in an English context with attention paid to implementation and subsequent referral and support pathways. Our study provides a minimum estimate of children needing developmental support (13.8%), with many more children likely to be experiencing moderate or mild delay but not identified by the ASQ-3 cut-offs for expected development.
《年龄与阶段问卷》第三版（ASQ - 3）是一种用于测量1至66个月儿童发育迟缓情况的工具，最初由美国开发。自2015年起，该测量数据在英格兰作为2至2.5岁健康访视审查的一部分进行收集，并在全国范围内整理到社区服务数据集（CSDS）中。已知CSDS并不完整，迄今为止，尚未有关于CSDS中ASQ - 3数据的任何已发表分析。
本研究旨在a）利用2018/19 - 2020/21年CSDS中的ASQ - 3数据，确定英格兰两岁儿童完整儿童发育数据的一个子集；b）使用该数据子集分析英格兰2至2.5岁儿童的发育情况。
本研究将地方当局和财政季度在CSDS中的ASQ - 3记录数量与全国公开可用的健康访视服务提供指标（HVSDM）进行比较，以确定CSDS中具有完整ASQ - 3记录的地方当局。本研究使用儿童是否达到预期发育水平的二元截止值和连续的ASQ - 3分数来描述该数据子集中的儿童发育情况。
在样本中来自64个地方当局的226,
505名拥有完整ASQ - 3数据的儿童中，86.2%达到了预期发育水平。来自最贫困社区的儿童（82.6%）、记录为黑人的儿童（78.9%）以及男孩（81.7%）达到预期发育水平的可能性较小。
为了全面了解英格兰的幼儿发育情况，CSDS中ASQ - 3数据的完整性需要提高。其次，为了解释国家CSDS中关于儿童发育的数据，应在英国背景下对ASQ - 3进行标准化和验证，并关注实施以及后续的转诊和支持途径。我们的研究提供了需要发育支持儿童的最低估计值（13.8%），可能还有更多儿童经历中度或轻度发育迟缓，但未被ASQ - 3预期发育截止值识别出来。
