INTRODUCTION The global SARS-CoV-2 pandemic has generated concern about contagion, especially among healthcare workers who are on the front line. OBJECTIVE To design and analyse the evidence of content validity, internal structure and reliability of a measure of concern about the spread of COVID-19 among Peruvian healthcare workers. MATERIAL AND METHODS Quantitative study and instrumental design. The scale was administered to 321 health science professionals (78 males and 243 females), whose ages ranged from 22 to 64 years (38.12±9.61). RESULTS Aiken's V-coefficient values were statistically significant. An exploratory factor analysis was performed which indicated the existence of a single factor, and confirmatory factor analysis (CFA) confirmed a satisfactory six-factor model. The CFA solution obtained adequate fit indices (RMSEA=0.079; p=0.05; TLI=0.967; IFC=0.980; GFI=0.971, and AGFI=0.931), and showed good internal consistency based on Cronbach's alpha coefficient (α=0.865; CI 95%, 0.83-0.89). CONCLUSIONS The scale of concern for COVID-19 infection is a valid and reliable brief measure that can be used for research and professional purposes.
