ABSTRACT
This study aimed to assess perceptions on the graphical informational materials designed to help in the fght against COVID-19 in Portugal and Brazil. We assessed the perceptions using an online survey incorporating the AttrakDiff2TM questionnaire. The results show that the perception of risk with relation to the COVID-19 pandemic is high among the respondents, and that they believe that they will have mild symptoms if infected by the virus. The results also show that the materials available in these countries were poorly designed and not effective in promoting adequate behaviour change. These fndings can contribute to future design projects whose aim is to design risk communication materials to inform and guide people facing health crisis situations. © 2021 John Benjamins Publishing Company.
