导论.基于互联网的众包越来越多地用于公共卫生领域的社会和行为研究，但众包数据的潜在普遍性仍不清楚。本研究评估了基于互联网的众包数据的人群代表性。2016年，共有3999名18至30岁的美国年轻人通过基于互联网的众包参与了2012-2013年全国成人烟草调查（NATS）。使用类似于NATS的程序创建事后采样权重。2016年进行了加权分析，比较了2012-2013年NATS关于人口统计学、烟草使用、烟草感知和产品警告标签安全性的众包和公开数据。众包样本中的人不太可能报告家庭年收入为5万美元或更高，电子烟，水管和雪茄的使用在众包样本中更为普遍。这两个样本的高比例表明吸烟是非常有害的，非常上瘾。非吸烟者和吸烟者报告香烟警告标签暴露的比例相当，但在众包样本中，吸烟者报告吸烟非常有害的可能性较低。我们的研究结果表明，众包样本可能在人口统计学上有所不同，并且在事后样本加权后，可能不会产生相对于人口数据的烟草使用流行率的可推广估计。然而，众包样本中的相关性分析可能合理地近似于人口数据。未来的研究可以建立在这项工作的基础上，通过测试额外的方法策略，以改善众包抽样策略。(C)2017爱思唯尔公司All rights reserved.
Introduction. Internet-based crowdsourcing is increasingly used for social and behavioral research in public health, however the potential generalizability of crowdsourced data remains unclear. This study assessed the population representativeness of Internet-based crowdsourced data.Methods. A total of 3999 U.S. young adults ages 18 to 30 years were recruited in 2016 through Internet-based crowdsourcing to complete measures taken from the 2012-2013 National Adult Tobacco Survey (NATS). Posthoc sampling weights were created using procedures similar to the NATS. Weighted analyses were conducted in 2016 to compare crowdsourced and publicly-available 2012-2013 NATS data on demographics, tobacco use, and measures of tobacco perceptions and product warning label exposure.Results. Those in the crowdsourced sample were less likely to report an annual household income of $50,000 or greater, and e-cigarette, waterpipe, and cigar use were more prevalent in the crowdsourced sample. High proportions of both samples indicated cigarette smoking is very harmful and very addictive. Comparable proportions of nonsmokers and smokers reported cigarette warning label exposure, however the likelihood of reporting that smoking is very harmful by frequency of warning label exposure was lower among smokers in the crowdsourced sample.Conclusions. Our findings indicate that crowdsourced samples may differ demographically and may not produce generalizable estimates of tobacco use prevalence relative to population data after post-hoc sample weighting. However, correlational analyses in crowdsourced samples may reasonably approximate population data. Future studies can build from this work by testing additional methodological strategies to improve crowdsourced sampling strategies. (C) 2017 Elsevier Inc. All rights reserved.
