Brief summary
The aim of this study is to test the impact of messages about COVID-19 vaccine booster doses in adults vaccinated against COVID-19 on intention to receive a COVID-19 vaccine booster dose. We will recruit adults vaccinated against COVID-19. Participants will receive 1 of 4 information conditions or a control. The 4 information conditions will focus on: the personal health impacts of vaccinating; family and community health impacts of vaccinating; non-health benefits of vaccinating; and personal choice and control associated with vaccinating. The control will be text about eligibility for a COVID-19 vaccine booster dose. Analysis will compare the primary outcome measure (intention to receive a COVID-19 vaccine booster dose) between intervention groups and the control (4 comparisons) using an ANOVA test. Secondary analyses will compare secondary outcome measures (beliefs about COVID-19 vaccines) between intervention groups and the control using an ANOVA test.
Interventions
The intervention is a short piece of written material designed to encourage uptake of booster doses of COVID-19 vaccines. The messages were designed specifically for this study. The intervention is delivered as part of an online experiment over the internet. After answering some questions about themselves, participants are asked to read the written information on their computer or phone screen. They are given the intervention once. The anticipated time needed to read the text is approximately 30
The intervention is a short piece of written material designed to encourage uptake of booster doses of COVID-19 vaccines. The messages were designed specifically for this study. The intervention is delivered as part of an online experiment over the internet. After answering some questions about themselves, participants are asked to read the written information on their computer or phone screen. They are given the intervention once. The anticipated time needed to read the text is approximately 30 seconds. Participants must spend a minimum of 30 seconds on this screen. This requirement to stay on the intervention screen is used for the purpose of encouraging adherence to the intervention. Arm 1 is a message focusing on personal health impacts of vaccinating Arm 2 is a message focusing on family and community health impacts of vaccinating Arm 3 is a message focusing on non-health benefits of vaccinating, such as freedom from public health restrictions and ability to travel Arm 4 is a message focusing on personal choice and control Arm 5 is a control message, providing information on COVID-19 vaccine booster dose eligibility.
