COMPONENT3: National Alcohol Survey (NAS) Resources - Scientific Core

这个国家酒精调查（NAS）资源的核心组成部分，活跃的所有年份，生成，管理和提供所需的NAS数据集3中心的研究组成部分（4，5和7）和其他独立的调查。自20世纪60年代以来，该中心每隔5年对美国成年人（18岁以上）进行一次NAS调查，自1979年以来进行了相当程度的标准化测量（第6次NAS或N6）。解决涉及现有数据集和新的NAS数据（例如，2009/10 N12调查）的下述步骤，该科学核心将（与熟练的实地工作组织一起）进行新的全国酒精调查（N13），设计改进包括双帧手机和固定电话采样，以及之前的非裔美国人，西班牙裔过度采样。对于这项住户调查，工具开发和试点工作于2013年开始，2014年投入使用，2015年初完成。在整个拟议期间，从第一年开始，我们将为研究人员（与统计和数据服务核心（SDSC），组件2合作）准备NAS数据集，以供中心研究组件中进行分析， 附属独立赠款，并由其他研究人员。数据集的增强将包括（a）清理和（B）加权数据，以及额外的常规方法导向任务，以（c）使用NAS饮料量和饮料类型数据以及中心目前的方法学家庭和酒吧饮料量研究，调整特定饮料中酒精含量的酒精消费量测量，无论是在现场还是在场外消费;（d）提供某些数据插补（例如，以解决缺失的收入数据）;（e）开发和确认算法（例如，用于计算平均摄入量或体积）;（f）创建所需的标度（例如，用于测量酒精使用障碍（AUD）和其他结构）;（g）与SDSC生物统计学家一起进行所需的心理测量分析，以提供基本的可靠性和有效性信息。对于N12和N13，我们将（h）添加从人口普查和其他档案来源提取的地理参考背景数据元素。准备就绪后，我们将（i）将N6至N12系列中的新数据与早期NAS数据（在当前中心周期内于2010年初收集）合并，然后在第5年添加N13数据。使用方法学部分7子研究1的结果，我们将引入新的分层后权重，以改善分析的估计值， 变量仅在陆线仪器中可用。最后，根据数据共享计划，我们将去识别NAS数据，并定期将数据集和支持文档放在公共领域，通过与酒精流行病学数据系统（AEDS）的协议，由CSR，Inc.为NlAAA和受资助者管理。

This National Alcohol Survey (NAS) Resources core component, active all years, generates, manages and provides needed NAS datasets to 3 Center research components (4, 5 and 7) and to other independent investigators. The Center has conducted NAS surveys of the adult (age 18 up) US population at about 5-year intervals since the 1960s, with considerable standardization of measures since 1979 (the 6th NAS or N6). Addressing steps described below involving the existing datasets and new NAS data (e.g, the 2009/10 N12 survey), this scientific core will conduct (in conjunction with a skilled fieldwork organization) a new National Alcohol Survey (N13), with design refinements Including dual-frame cell phone and landline sampling, plus as earlier, African American, Hispanic oversamples. For this household survey, instrument development and piloting begins in 2013, fielding in 2014, with completion by early 2015. Throughout the proposed period, beginning in year 1, we will prepare for investigators (working with the Statistical and Data Services Core (SDSC), component 2) NAS datasets for analysis in the Center's research components, affiliated independent grants, and by other researchers. Dataset enhancements will include (a) cleaning and (b) weighting data, and additional routine methodologically oriented tasks to (c) adjust alcohol consumption measures for the alcohol content in specific beverages, consumed on- and off premise, using both NAS drink size and beverage type data and the Center's present methodological drink size home and bar studies; (d) provide certain data imputations (e.g., to address missing income data); (e) develop and confirm algorithms (e.g., for calculating mean intake, or volume); (f) create needed scales (e.g., for measuring Alcohol Use Disorder (AUD) and other constructs); and (g) conduct, with the SDSC biostatisticians, needed psychometric analyses to provide basic reliability and validity information. For N12 and N13, we will (h) add geo-referenced contextual data elements drawn from Census and other archival sources. When ready, we will (i) merge new with earlier NAS data in the series extending from N6 through N12 (gathered by early 2010 during the current Center Cycle) then, in year 5, adding N13 data. Using the Methodology component 7 Sub-Study 1 results, we will introduce new post-stratification weights to improve estimates from analyses requiring variables available only in the landline instrument. Finally, per the data-sharing plan, we wilt de-identify the NAS data and periodically place datasets and supporting documentation in the public domain, by agreement with the Alcohol Epidemiological Data System (AEDS), managed for NlAAA and grantees by CSR, Inc.
