The Canadian COVID-19 Experiences Project: Design and Protocol
Abstract
Introduction
Vaccine hesitancy and inconsistent mitigation behavior performance have been significant challenges throughout the COVID-19 pandemic. In Canada, despite relatively high vaccine availability and uptake, willingness to accept booster shots and maintain mitigation behaviors in the post-acute phase of COVID-19 remain uncertain. The aim of the Canadian COVID-19 Experiences Project (CCEP) is two-fold: 1) to identify social-cognitive and neurocognitive correlates of vaccine hesitancy and mitigation behaviors, and 2) to identify optimal communication strategies to promote vaccination and mitigation behaviors into the post-acute phase of the pandemic.
Methods and analyses
The CCEP is comprised of two components: a conventional population survey (Study 1) and a functionally interconnected laboratory study (Study 2). Study 1 will involve 3 waves of data collection. Wave 1, completed between 28 September and 21 October, 2021, recruited 1,958 vaccine-hesitant (49.8%) and fully vaccinated (50.2%) adults using quota sampling to ensure maximum statistical power. Measures included a variety of social cognitive (e.g., beliefs, intentions) and neurocognitive (e.g., delay discounting) measures, followed by an opportunity to view and rate a set of professionally produced COVID-19 public service announcement (PSA) videos for perceived efficacy. Study 2 employs the same survey items and PSAs but coupled with lab-based eye tracking and functional brain imaging to directly quantify neural indicators of attention capture and self-reflection in a smaller community sample. In the final phase of the project, subjective impressions and neural indicators of PSA efficacy will be compared and used to inform recommendations for construction of COVID-19 PSAs into the post-acute phase of the pandemic.
Ethics and dissemination
The CCEP has received ethical review and approval by the University of Waterloo Office of Research Ethics. Findings will be disseminated through peer-reviewed publications and presentations at scientific meetings.
