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

这个国家酒精调查（NAS）资源核心组件，常年活跃，生成、管理并向3个中心研究组件（4、5和7）和其他独立调查员提供所需的NAS数据集。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，测量方法相当标准化（第6次NAS或N6）。为解决涉及现有数据集和新的NAS数据（例如，2009/10年N12调查）的以下步骤，该科学核心将（与熟练的实地调查组织合作）进行新的全国酒精调查（N13），并对设计进行改进，包括双框架手机和固定电话抽样，以及之前的非裔美国人、西班牙裔过度抽样。对于这项家庭调查，仪器开发和试点将于2013年开始，2014年投入使用，2015年初完成。在整个拟议期间，从第1年开始，我们将为调查人员（使用统计和数据服务核心（SDSC），组件2）NAS数据集准备，以便在中心的研究组件中进行分析。

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.
