Message framing and COVID-19 vaccination intention: Moderating roles of partisan media use and pre-attitudes about vaccination.

One of the ways to overcome the sheer devastation of the COVID-19 pandemic is to get vaccinated. However, vaccine hesitancy could be a significant barrier. The main purposes of the current study are to examine the impact of four types of theory-driven messages on COVID-19 vaccination intention and to understand the moderating role of partisan media use and vaccination attitudes. The study used a between-subject randomized online experiment with four conditions. The manipulation messages were presented as screenshots from the CDC's Facebook page. The total number of participants were 387 (female 43%, mean age 37 years). The participants were from the U.S. and older than 18 years. The findings show that loss vs. gain message frames did not have any impact on COVID-19 vaccine intention. The moderating effects of conservative media and attitudes show that in general, those who consumed lower conservative media and held positive attitudes were higher on vaccine intention, and individual vs. collective frames did not have a strong impact. However, among those participants who scored high on conservative media use, and held negative vaccination attitudes, the individual frame had a higher impact on vaccine intention. The current study experimentally tested the intertwined relationships among message frames, partisan media use, and attitudes on vaccine intention. These relationships are critical considering the political nature of the pandemic. [ABSTRACT FROM AUTHOR]
