Campaigns for mask-wearing have become widespread on digital platforms during the COVID-19 outbreak and have garnered varied responses in the form of comments. The present study conducts a 2 (comment position: pro-mask wearing vs. anti-mask wearing) × 2 (comment tone: civil vs. uncivil) between-subjects experiment to investigate whether and how the position and tone of comments accompanying a health campaign on social media affect people's psychological reactance toward the campaign. The results show that although anti-mask wearing comments following a social media mask-promoting post provoke individuals' perception about others' disapproval of the post, the perception did not trigger the individuals' psychological reactance to the post. Nevertheless, uncivil comments elicit anger, which arouses reactance and cause persuasion failure.
