Reliable estimates of health-related behaviours, such as levels of alcohol consumption in the population, are required to formulate and evaluate policies. National surveys provide such data; validity depends on generalisability, but this is threatened by declining response levels. Attempts to address bias arising from non-response are typically limited to survey weights based on sociodemographic characteristics, which do not capture differential health and related behaviours within categories. This project aims to explore and address non-response bias in health surveys with a focus on alcohol consumption.
The Scottish Health Surveys (SHeS) aim to provide estimates representative of the Scottish population living in private households. Survey data of consenting participants (92% of the achieved sample) have been record-linked to routine hospital admission (Scottish Morbidity Records (SMR)) and mortality (from National Records of Scotland (NRS)) data for surveys conducted in 1995, 1998, 2003, 2008, 2009 and 2010 (total adult sample size around 40 000), with maximum follow-up of 16 years. Also available are census information and SMR/NRS data for the general population. Comparisons of alcohol-related mortality and hospital admission rates in the linked SHeS-SMR/NRS with those in the general population will be made. Survey data will be augmented by quantification of differences to refine alcohol consumption estimates through the application of multiple imputation or inverse probability weighting. The resulting corrected estimates of population alcohol consumption will enable superior policy evaluation. An advanced weighting procedure will be developed for wider use.
Ethics approval for SHeS has been given by the National Health Service (NHS) Multi-Centre Research Ethics Committee and use of linked data has been approved by the Privacy Advisory Committee to the Board of NHS National Services Scotland and Registrar General. Funding has been granted by the MRC. The outputs will include four or five public health and statistical methodological international journal and conference papers.

为了制定和评估政策，需要对与健康相关的行为（如人群中的饮酒水平）进行可靠的估计。全国性调查提供了此类数据；有效性取决于普遍性，但这受到回应水平下降的威胁。为了解决因不回应而产生的偏差，通常仅限于基于社会人口特征的调查权重，而这些权重并不能捕捉到类别内不同的健康和相关行为。本项目旨在探讨和解决以酒精消费为重点的健康调查中的无应答偏差问题。
苏格兰健康调查（SHeS）旨在提供代表居住在私人家庭中的苏格兰人口的估计值。同意参与的调查对象（实现样本的 92%）的数据已与常规住院（苏格兰发病率记录（SMR））和死亡率（来自苏格兰国家记录（NRS））记录相关联，用于 1995 年、1998 年、2003 年、2008 年、2009 年和 2010 年进行的调查（总成人样本量约为 40000 人），最长随访时间为 16 年。还可获得人口普查信息和一般人群的 SMR/NRS 数据。将相关联的 SHeS-SMR/NRS 中的酒精相关死亡率和住院率与一般人群中的数据进行比较。通过应用多次插补或逆概率加权来量化差异，以改进酒精消费估计，从而扩充调查数据。通过这种方式校正后的人口饮酒量估计值将使政策评估更加完善。将开发一种先进的加权程序，以供更广泛的使用。
SHeS 的伦理批准已获得国家卫生服务（NHS）多中心研究伦理委员会的批准，并且使用相关数据已获得苏格兰国民保健服务委员会隐私咨询委员会和登记总干事的批准。资金由 MRC 提供。产出将包括四到五份国际公共卫生和统计方法学期刊和会议论文。
