To conduct a discrete-choice experiment to quantify Americans' acceptance of severe acute respiratory syndrome coronavirus 2 infection risks for earlier lifting of social-distancing restrictions and diminishing the pandemic's economic impact.
We designed a discrete-choice experiment to administer 10 choice questions to each respondent representing experimentally controlled pairs of scenarios defined by when nonessential businesses could reopen (May, July, or October 2020), cumulative percentage of Americans contracting coronavirus disease 2019 (COVID-19) through 2020 (2% to 20%), time for economic recovery (2 to 5 years), and the percentage of US households falling below the poverty threshold (16% to 25%). Respondents were recruited by SurveyHealthcareGlobus.
A total of 5953 adults across all 50 states completed the survey between May 8 and 20, 2020. Latent-class analysis supported a 4-class model. The largest class (36%) represented COVID-19 risk-minimizers, reluctant to accept any increases in COVID-19 risks. About 26% were waiters, strongly preferring to delay reopening nonessential businesses, independent of COVID-19 risk levels. Another 25% represented recovery-supporters, primarily concerned about time required for economic recovery. This group would accept COVID-19 risks as high as 16% (95% CI: 13%-19%) to shorten economic recovery from 3 to 2 years. The final openers class prioritized lifting social distancing restrictions, accepting of COVID-19 risks greater than 20% to open in May rather than July or October. Political affiliation, race, household income, and employment status were all associated with class membership (P<.01).
Americans have diverse preferences pertaining to social-distancing restrictions, infection risks, and economic outcomes. These findings can assist elected and public-health officials in making difficult policy decisions related to the pandemic.
通过离散选择实验来量化美国人对 2019 年冠状病毒病(COVID-19)感染风险的接受程度,以提前放宽社交距离限制并减轻大流行对经济的影响。
我们设计了一个离散选择实验,向每位受访者提供 10 个选择题,代表通过 2020 年(5 月、7 月或 10 月)非必要企业重新开放、2020 年累计有多少美国人感染冠状病毒病 2019(COVID-19)(2%至 20%)、经济复苏所需时间(2 至 5 年)和美国有多少家庭低于贫困线(16%至 25%)的情况进行实验控制。SurveyHealthcareGlobus 通过调查的方式招募了参与者。
2020 年 5 月 8 日至 20 日,全美共有 5953 名成年人完成了调查。潜在类别分析支持 4 类模型。最大的类别(36%)代表 COVID-19 风险最小化者,不愿意接受 COVID-19 风险的任何增加。大约 26%的人是服务员,强烈希望推迟重新开放非必要企业,而不考虑 COVID-19 的风险水平。另一个 25%的人是复苏支持者,主要关注经济复苏所需的时间。这个群体愿意接受高达 16%(95%CI:13%-19%)的 COVID-19 风险,以将经济复苏从 3 年缩短至 2 年。最后一类是开放者,优先考虑放宽社交距离限制,愿意接受 20%以上的 COVID-19 风险,以便在 5 月而不是 7 月或 10 月重新开放。政治派别、种族、家庭收入和就业状况都与类别成员有关(P<.01)。
美国人对于社交距离限制、感染风险和经济结果有不同的偏好。这些发现可以帮助当选官员和公共卫生官员做出与大流行相关的艰难政策决策。
