The National Center for Health Statistics is assessing the usefulness of recruited web panels in multiple research areas. One research area examines the use of close-ended probe questions and split-panel experiments for evaluating question-response patterns. Another research area is the development of statistical methodology to leverage the strength of national survey data to evaluate, and possibly improve, health estimates from recruited panels. Recruited web panels, with their lower cost and faster production cycle, in combination with established population health surveys, may be useful for some purposes for statistical agencies. Our initial results indicate that web survey data from a recruited panel can be used for question evaluation studies without affecting other survey content. However, the success of these data to provide estimates that align with those from large national surveys will depend on many factors, including further understanding of design features of the recruited panel (e.g. coverage and mode effects), the statistical methods and covariates used to obtain the original and adjusted weights, and the health outcomes of interest.
国家卫生统计中心正在评估招募的网络样本组在多个研究领域的实用性。一个研究领域考察封闭式探测性问题和分样本组实验在评估问题-回答模式方面的应用。另一个研究领域是开发统计方法，以利用全国性调查数据的优势来评估并可能改进从招募的样本组得出的健康估计值。招募的网络样本组成本较低且生产周期较快，与现有的人群健康调查相结合，可能对统计机构的某些目的有用。我们的初步结果表明，来自招募样本组的网络调查数据可用于问题评估研究，而不会影响其他调查内容。然而，这些数据能否成功提供与大型全国性调查结果一致的估计值将取决于许多因素，包括对招募样本组设计特征（如覆盖范围和模式效应）的进一步了解、用于获得原始权重和调整权重的统计方法及协变量，以及所关注的健康结果。
