Online Games to Help Canadian and U.S. Adults Identify COVID-19 and Vaccine Misinformation: Three Sequential Randomized Studies

Sponsor: University of South Carolina

Summary

COVID-19 misinformation contributed to vaccine hesitancy and preventable illness. This record covers three sequential randomized studies (conducted in Canada and the United States, November-December 2020) testing whether a brief online game helps adults identify COVID-19 and vaccine misinformation. In the game, participants judged whether statements about COVID-19 or COVID-19 vaccines were true or false and immediately received the correct answer with a brief evidence-based explanation, delivered in a game-like format with points, ranks, and feedback. Study 1 (Canada, n = 2,018) randomized participants to complete the knowledge assessment either before playing the game or immediately after playing it. Studies 2 (U.S., n = 822) and 3 (U.S., n = 797) compared the game against the identical corrective content presented as plain text, for general COVID-19 misinformation and vaccine-specific misinformation, respectively. The hypothesis was that gamified corrective information produces more accurate knowledge than non-gamified information. The primary outcome was accuracy in identifying true and false claims; vaccination intention was a secondary outcome.
