Vital Health Stat 2. 1999 Jul(126):1-119.
This report presents a major portion of the research carried out for the 1995-2004 redesign of the National Health Interview Survey. The primary focus of the 1995-2004 NHIS redesign research was to explore sample design options to improve the reliability of NHIS statistics for racial, ethnic, economic, and geographic domains. Another objective was to assess the integration of the sample designs of the NCHS surveys of health care providers and NHIS.
A number of research tasks were carried out by Westat, Inc., to explore the feasibility and cost of various sample design options for the 1995-2004 National Health Interview Survey redesign. This report provides a detailed description of the research that was carried out.
The research results presented in this report were the primary basis for assessing the technical soundness and costs for a number of design alternatives. The first option, called the alpha option, was developed under the assumption of a 50-percent data collection budget increase. The second option, called the beta option, was developed under the assumption of no change in the data collection budget. The beta option was the design implemented in 1995. Other important research items described in this report include oversampling methods for minority populations and dual-frame sampling methods. The research results in this report also led to additional research, primarily in the area of survey integration. A more detailed description of the 1995-2004 NHIS design will appear in a forthcoming NCHS Series 2 report titled Design and Estimation for the 1995-2004 National Health Interview Survey.
本报告展示了为1995 - 2004年全国健康访谈调查重新设计所开展的大部分研究。1995 - 2004年全国健康访谈调查重新设计研究的主要重点是探索样本设计选项，以提高全国健康访谈调查在种族、民族、经济和地理领域统计数据的可靠性。另一个目标是评估国家卫生统计中心（NCHS）的医疗服务提供者调查与全国健康访谈调查样本设计的整合情况。
Westat公司开展了多项研究任务，以探索1995 - 2004年全国健康访谈调查重新设计的各种样本设计选项的可行性和成本。本报告详细描述了所开展的研究。
本报告中呈现的研究结果是评估多种设计方案的技术合理性和成本的主要依据。第一种方案称为α方案，是在数据收集预算增加50%的假设下制定的。第二种方案称为β方案，是在数据收集预算不变的假设下制定的。β方案是1995年实施的设计。本报告中描述的其他重要研究项目包括少数族裔人群的过抽样方法和双框抽样方法。本报告中的研究结果还引发了更多研究，主要集中在调查整合领域。关于1995 - 2004年全国健康访谈调查设计的更详细描述将出现在即将发布的国家卫生统计中心第2系列报告《1995 - 2004年全国健康访谈调查的设计与估计》中。
