We examined the link between constructive patriotism, glorification, and conventional patriotism and COVID-19-related attitudes and behaviors at different stages of the pandemic in Poland. In Study 1 (N = 663), constructive patriotism was positively associated with support for internal measures (e.g., raising awareness about health practices). Glorification was negatively linked to support for such measures and positively connected to support for external measures (e.g., closing the borders). In Study 2 (N = 522), constructive patriots showed greater compliance with hygiene and social distance practices. In Study 3 (N = 633), the attribution of responsibility for fighting the crisis to the state and particularly to individuals underlined the link between constructive patriotism and compliance with health practices. Additionally, constructive patriotism was linked to support for international collaboration. Study 4 (N = 1051), conducted on a representative sample, further corroborated these findings. The results regarding conventional patriotism were not consistent across studies.
