Here we investigate public preferences for coronavirus disease 2019 (COVID-19) certificates in the Netherlands, and whether these preferences differ between subgroups in the population.
A survey including a discrete choice experiment was administered to 1500 members of the adult population of the Netherlands. Each participant was asked to choose between hypothetical COVID-19 certificates that differed in seven attributes: the starting date, and whether the certificate allowed gathering with multiple people, shopping without appointment, visiting bars and restaurants, visiting cinemas and theatres, attending events, and practising indoor sports. Latent class models (LCMs) were used to determine the attribute relative importance and predicted acceptance rate of hypothetical certificates.
Three classes of preference patterns were identified in the LCM. One class a priori opposed a certificate (only two attributes influencing preferences), another class was relatively neutral and included all attributes in their decision making, and the final class was positive towards a certificate. Respondents aged > 65 years and those who plan to get vaccinated were more likely to belong to the latter two classes. Being allowed to shop without appointment and to visit bars and restaurants was most important to all respondents, increasing predicted acceptance rate by 12 percentage points.
Preferences for introduction of a COVID-19 certificate are mixed. A certificate that allows for shopping without appointment and visiting bars and restaurants is likely to increase acceptance. The support of younger citizens and those who plan to get vaccinated seems most sensitive to the specific freedoms granted by a COVID-19 certificate.
本研究旨在调查荷兰公众对 2019 冠状病毒病（COVID-19）证书的偏好，以及这些偏好是否在人群亚组之间存在差异。
对荷兰成年人口的 1500 名成员进行了一项包含离散选择实验的调查。每位参与者被要求在七个属性不同的假设 COVID-19 证书之间进行选择：起始日期，以及证书是否允许与多人聚会、无需预约购物、访问酒吧和餐馆、参观电影院和剧院、参加活动以及进行室内运动。使用潜在类别模型（LCM）来确定属性的相对重要性和假设证书的预测接受率。
LCM 确定了三种偏好模式类别。一类预先反对证书（只有两个属性影响偏好），另一类相对中立，将所有属性纳入其决策，最后一类对证书持积极态度。年龄>65 岁和计划接种疫苗的受访者更有可能属于后两类。允许无需预约购物和访问酒吧和餐馆对所有受访者最重要，可将预测接受率提高 12 个百分点。
对引入 COVID-19 证书的偏好存在分歧。允许无需预约购物和访问酒吧和餐馆的证书可能会提高接受率。年轻公民和计划接种疫苗的人的支持似乎对 COVID-19 证书授予的特定自由最为敏感。
