简要总结

Uptake of vaccination against COVID-19 is key to controlling the pandemic. However, a significant proportion of people report that they do not intend to have a vaccine, often because of concerns they have about its side effects or safety. It is important to identify ways to communicate information about the vaccines that facilitate informed decisions rather than promoting uptake through coercion. This study will assess whether theory-based messages can change beliefs and increase intentions to receive a COVID-19 vaccine in Scotland. The messages will be based on publicly available information about the need for COVID-19 vaccination and the safety of the vaccines, and structured to address specific types of treatment beliefs. Participants will be randomised to either a group shown the messages or a control group shown general information messages about the COVID-19 virus and vaccination programme. By comparing the two groups we aim to test what impact the theory-based messages have on intentions and beliefs about COVID-19 vaccination.

盲法说明

Participants will not be blinded to the assigned intervention but will not be informed of the purpose of the study until they have completed the follow-up survey, at which point they will be debriefed. Investigators will be blinded to allocation because all procedures will be undertaken digitally and remotely without any investigator contact with participants.

结局指标

主要结局

Covid-19 vaccination intention measured by a single item and aggregated as the proportion of intenders.

时间窗: Immediately post-intervention

Participants will be asked: "If you were invited to have a COVID-19 vaccination would you take the vaccine?" Those responding "yes, probably" or "yes, definitely" will be treated as intenders. Those responding "don't know", "probably not" or "definitely not" will be treated as non-intenders.

次要结局

  • Mean perceived necessity score as assessed by the BMQ(Immediately post-intervention)
  • Mean COVID-19 illness coherence score as assessed by the IPQ-R(Immediately post-intervention)
  • Mean perceived concerns score as assessed by the BMQ(Immediately post-intervention)
