Abstract：
Objective. To enable future open-air festivals during a pandemic, model festivals tested restricted access and behavioural rules to prevent SARS-CoV-2 transmissions. However, the uptake of health-protective measures depends on informed acceptance, meaning people are more likely to follow measures if they understand their effectiveness and related disease risks. Design and main outcome measures. With a series of online surveys, we studied risk perceptions of 6,500 festival guests and the association of perceived effectiveness of protective behaviours with reported compliance. In a scenario-based online experiment (N = 1,958) among festival guests, we tested the effect of informing transparently about the risk-reducing potential of protective measures at festivals on the intention to attend hypothetical events. Results. We found that guests tended to overestimate infection risks while still perceiving them as low. Self-reported mask wearing and distancing at and around the festivals could not be associated with the understanding of the measures\' effectiveness. However, in addition to protective measures themselves, providing transparent information about their absolute risk-reducing effect increased intentions to attend festivals that employ varying protective measures. Conclusion. Our findings suggest that the acceptance of protected festivals can be influenced by transparent information about the effectiveness of protective measures. This calls for further research on evidence-based public health communications to improve their impact.
摘要：
Objective.为了在大流行期间启用未来的露天节日，模型节日测试了限制访问和行为规则，以防止SARS-CoV-2传播。然而,采取健康保护措施取决于知情的接受，这意味着如果人们了解这些措施的有效性和相关的疾病风险，他们更有可能遵循这些措施。设计和主要成果措施。通过一系列在线调查，我们研究了6,500名节日嘉宾的风险认知,以及保护性行为的感知有效性与报告的依从性之间的关联.在节日嘉宾的基于场景的在线实验(N=1,958)中，我们测试了在节日中透明地告知保护性措施降低风险的潜力对参加假设活动的意向的影响.结果。我们发现，客人倾向于高估感染风险，同时仍然认为它们很低。自我报告的戴口罩和节日前后的距离不能与对措施有效性的理解相关联。然而,除了保护措施本身，提供有关其绝对风险降低效果的透明信息，增加了参加采用各种保护措施的节日的意图。结论。我们的发现表明，有关保护措施有效性的透明信息可以影响受保护节日的接受度。这就要求对基于证据的公共卫生传播进行进一步研究，以改善其影响。
