Cross-cultural measurement invariance of the fear of COVID-19 scale in three Portuguese-speaking countries.

This study evaluated the measurement invariance of the Portuguese version of the Fear of COVID-19 Scale (FCV-19S) across three countries: Brazil (South America), Mozambique (East Africa), and Portugal (Southwest Europe). A total of 8694 participants were recruited through convenience sampling (7430 Brazilians, 387 Mozambicans, and 877 Portuguese adults). The unidimensional structure of the FCV-19S fitted well with each country's data.
