The National Center for Health Statistics' (NCHS) Research and Development Survey (RANDS) is a series of commercial panel surveys collected for methodological research purposes. In response to the COVID-19 pandemic, NCHS expanded the use of RANDS to rapidly monitor aspects of the public health emergency. The RANDS during COVID-19 survey was designed to include COVID-19 related health outcome and cognitive probe questions. Rounds 1 and 2 were fielded June 9-July 6, 2020 and August 3-20, 2020 using the AmeriSpeak® Panel. Existing and new approaches were used to: 1) evaluate question interpretation and performance to improve future COVID-19 data collections and 2) to produce a set of experimental estimates for public release using weights which were calibrated to NCHS' National Health Interview Survey (NHIS) to adjust for potential bias in the panel. Through the expansion of the RANDS platform and ongoing methodological research, NCHS reported timely information about COVID-19 in the United States and demonstrated the use of recruited panels for reporting national health statistics. This report describes the use of RANDS for reporting on the pandemic and the associated methodological survey design decisions including the adaptation of question evaluation approaches and calibration of panel weights.
美国国家卫生统计中心（NCHS）的研发调查（RANDS）是一系列为方法学研究目的而开展的商业面板调查。为应对新冠疫情，NCHS扩大了RANDS的使用范围，以快速监测公共卫生紧急事件的各个方面。新冠疫情期间的RANDS调查旨在纳入与新冠疫情相关的健康结果和认知探测问题。第1轮和第2轮调查于2020年6月9日至7月6日以及2020年8月3日至20日通过美国民意调查小组（AmeriSpeak® Panel）开展。采用了现有和新的方法来：1）评估问题的解释和表现，以改进未来的新冠疫情数据收集；2）使用根据NCHS的国家健康访谈调查（NHIS）校准的权重生成一组供公开发布的实验性估计值，以调整面板中的潜在偏差。通过扩展RANDS平台和持续进行方法学研究，NCHS报告了美国有关新冠疫情的及时信息，并展示了利用招募的面板来报告国家卫生统计数据的情况。本报告描述了使用RANDS报告疫情的情况以及相关的方法学调查设计决策，包括问题评估方法的调整和面板权重的校准。
