COVID-19 vaccine hesitancy: The effects of combining direct and indirect online opinion cues on psychological reactance to health campaigns

作者：

Highlights：

• Anti-vaccine comments on vaccine-promoting posts provoked psychological reactance to the posts in audiences of the posts.

• Anti-vaccine comments misled audiences by making them believe that others dislike and reject the vaccination education.

• When pro-vaccine comments were accompanied by rejection emojis, they triggered as much reactance as anti-vaccine comments.

• Audiences' pre-existing attitudes did not affect the effects of the combined direct and indirect opinion cues.

• Greater reactance increased people's COVID-19 vaccine hesitancy.
