The 2017 Longitudinal Studies Strategic Review (Davis-Kean, Chambers, Davidson, Kleinert, Ren and Tang, 2018) made a series of recommendations on innovative ways to enhance and to invest in opportunities for longitudinal research in the UK. One of the key recommendations to the ESRC was to commission a new birth cohort with an accelerated longitudinal design. The accelerated longitudinal design engages multiple cohorts simultaneously, each one starting at a different age and then following a 'suite' of aligned cohort groupings over time. In this proposal we investigate high-level design options and feasibility for an accelerated longitudinal design in the UK for a cohort of individuals starting soon after birth and a second or multiple cohorts starting in childhood and following each one over time, at least to age 18. The 2017 Longitudinal Studies Strategic Review mentions 'pivotal age periods (to be determined)'. Given the aim of sampling from an 'administrative spine' which in practice does not exist, we can assume that one age point would be 0, e.g. from the registry of births. Another key administrative source for children is the School Census and it is natural to take the age of 5 (the start of compulsory schooling) as an additional age point. A third age point could be the age of 16 (the end of compulsory schooling). We note that the issue of following a cohort during pregnancy may be problematic due to a lack of a sampling frame. More specifically, we investigate theoretical aspects of an accelerated longitudinal design versus a traditional single cohort with respect to: statistical power and precision of estimates to be able to examine key research questions; consideration of geographical aspects and adequate sample sizes at the UK national and regional level and in vulnerable subgroups (including booster sampling); statistical analysis under multiple cohorts; comparability of measures across cohorts and across sweeps; missing data and attrition.

2017年纵向研究战略审查（戴维斯-基恩，钱伯斯，戴维森，克莱纳特，任和唐，2018年）提出了一系列关于创新方法的建议，以加强和投资于英国纵向研究的机会。向ESRC提出的关键建议之一是委托采用加速纵向设计的新出生队列。加速纵向设计同时涉及多个队列，每个队列从不同的年龄开始，然后随着时间的推移遵循“一套”对齐的队列分组。在这项提案中，我们调查了高层次的设计选项和可行性，在英国加速纵向设计的一个队列的个人出生后不久开始，第二个或多个队列开始在童年和以下每一个随着时间的推移，至少到18岁。2017年《纵向研究战略评论》提到了“关键年龄段（待定）”。鉴于从实际上并不存在的“行政脊柱”中取样的目的，我们可以假设一个年龄点是0，例如从出生登记处。儿童的另一个重要行政来源是学校普查，自然将5岁（义务教育开始）作为一个额外的年龄点。第三个年龄点可以是16岁（义务教育结束）。我们注意到，由于缺乏抽样框架，在怀孕期间跟踪队列的问题可能会有问题。更具体地说，我们研究了加速纵向设计与传统单一队列的理论方面：统计功效和估计精度，以便能够检查关键研究问题;考虑地理因素以及英国国家和地区层面以及弱势亚组的足够样本量（包括加强抽样）;多个群组下的统计分析;群组间和抽样间计量的可比性;缺失数据和自然减员。
