The psychological impact of the COVID-19 pandemic and the role of resilience: cross cultural differences between Brazil, Italy, and the United States.

Objective: Restrictive measures consequent to the COVID-19 pandemic have had a significant psychological impact on everyday life in the general population, even though differences between countries remain poorly investigated. The present study sought to examine the different psychological impacts and resilience of the pandemic among three of the most heavily hit countries: Brazil, Italy, and the United States.

Methods: This cross-sectional study separately involved three national community populations, namely the Brazilian, the Italian, and the American population.

The Brazilian version of the Constant-Murley Score (CMS-BR): convergent and construct validity, internal consistency, and unidimensionality.

Objectives: To translate and culturally adapt the CMS and assess the validity of the Brazilian version (CMS-BR).

Methods: The translation was carried out according to the back-translation method by four independent translators. The produced versions were synthesized through extensive analysis and by consensus of an expert committee, reaching a final version used for the cultural adaptation.
