In this study (N = 110) factors influencing formation of attitudes toward COVID-19 related restrictions as well as factors influencing stability or change of these attitudes were tested. Specifically, the study concentrated on two possible determinants of formation and changing attitudes toward COVID-19 related restrictions – fear of coronavirus and presenting restriction in forbid vs. allow frames. A restriction presented in the forbid frame was rejected more strongly than a restriction presented in the allow frame. For changing attitudes, a mere thought paradigm was used. This activity was not able to change these negative attitudes toward a forbid framed restriction. A higher level of fear of coronavirus was related to a more positive (or rather – less negative) attitude toward an allow framed restriction and allows this attitude to be changed to be more supportive of restrictions than initially. Moreover, the effect of fear was partially mediated by the changes in the confidence of initial attitude inconsistent thoughts.
