The aim of this study was to compare the effects of different types of COVID-19 certification policy on subsequent behavioural expectations.
4 × 2 between-subjects pre-registered randomised controlled trial.
In August 2022, participants ( = 2726) in England were presented with a scenario describing a rise in COVID-19 infections and the introduction of new protective measures. The protective measures described varied with regards to the setting (healthcare vs. recreational) and the type of policy (no certification vs. vaccination vs. vaccination free Lateral Flow test vs. vaccination Lateral Flow test at personal cost). Participants then answered questions on their expectations to receive another dose of the COVID-19 vaccine, to receive the seasonal influenza vaccine and to adhere to other protective behaviours following the announcement, as well as questions based on Self-Determination Theory, COVID-19 vaccine hesitancy and broader vaccine hesitancy.
We found no main effects of setting or type of certification on expectation to receive the next dose of the COVID-19 vaccine, to receive the seasonal influenza vaccine, or to adhere to other protective measures, when controlling for baseline expectations.
These findings suggest that it is unlikely that the concept of certification, however it is framed, alters inclinations in the English population towards COVID-19 and seasonal flu vaccination or inclinations towards adhering to other protective behaviours within settings to which certification would apply. These findings are based on a hypothetical scenario and should be interpreted with caution.
本研究旨在比较不同类型的新冠病毒认证政策对后续行为预期的影响。
4×2组间预先注册的随机对照试验。
2022年8月，向英格兰的参与者（n = 2726）呈现了一个情景，描述新冠病毒感染率上升以及新的防护措施出台。所描述的防护措施在场所（医疗保健场所与娱乐场所）和政策类型（无认证、接种疫苗、免费横向流动检测、自费接种疫苗并进行横向流动检测）方面有所不同。参与者随后回答了关于他们在公告后接受另一剂新冠病毒疫苗、接受季节性流感疫苗以及遵守其他防护行为的预期问题，以及基于自我决定理论、新冠病毒疫苗犹豫和更广泛的疫苗犹豫的问题。
在控制基线预期后，我们发现场所或认证类型对接受下一剂新冠病毒疫苗、接受季节性流感疫苗或遵守其他防护措施的预期没有主要影响。
这些发现表明，无论认证概念如何构建，都不太可能改变英国人群对新冠病毒和季节性流感疫苗接种的倾向，或改变在适用认证的场所内遵守其他防护行为的倾向。这些发现基于一个假设情景，应谨慎解读。
