Scale of Concern about COVID-19 Infection in Peruvian Health Care Workers. / Escala de preocupación por el contagio de la COVID-19 en personal de la salud peruano.

ABSTRACT

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.
