RESUMO
Introducción: La pandemia mundial producida por el SARS-CoV-2 ha generado preocupación por el contagio, sobre todo en el personal de salud que está en primera línea. Objetivo: Diseñar y analizar las evidencias de validez de contenido, estructura interna y confiabilidad de una medida de preocupación por el contagio de COVID-19 en personal de salud peruano. Material y métodos: Estudio cuantitativo y diseño instrumental. La escala se aplicó a 321 profesionales de ciencias de la salud (78 varones y 243 mujeres) con edades comprendidas entre los 22 y los 64 (38,12 ± 9,61) an os. Resultados: Los valores del coeficiente V de Aiken fueron estadísticamente significativos. Se realizó un análisis factorial exploratorio, que indicó la existencia de un solo factor. El análisis factorial confirmatorio (AFC) confirmó un modelo satisfactorio de 6 ítems en 1 solo factor. La solución del AFC obtuvo índices de ajuste adecuados (RMSEA = 0,079; p = 0,05; TLI = 0,967; CFI = 0,980; GFI = 0,971 y AGFI = 0,931); además; mostró una buena consistencia interna según el coeficiente alfa de Cronbach (a = 0,865; IC95%, 0,83-0,89). Conclusiones: La escala de preocupación por el contagio de la COVID-19 es una medida breve válida y confiable que se puede utilizar para fines de investigación y función profesional.
A B S T R A C T 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 (a = 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.

RESUMO
OBJECTIVE: The increase in COVID-19 cases is generating fear and concern in society, which generates an emotional response that influences the adoption of health-related behaviors. The objective of the study is to design and validate the Scale of Worry for Contagion of COVID-19 (PRE-COVID-19). METHOD: The study had a descriptive cross-sectional design. The population were young people and adults who resided in the cities of Lima and Callao (Perú) during the declaration of the national health emergency due to the COVID-19 pandemic, during the period from March 16 to 27, 2020, who were recruited through a non-probability sample. The PRE-COVID-19, the WHO-Five Well-Being Index, the Generalized Anxiety Disorder Scale-2 and a single item were applied to measure the general perception of health. The scales were shared using a Google form through social networks. An internal consistency reliability analysis and structural equation models were performed, specifically confirmatory factor analysis. The recommendations of the Declaration of Helsinki and the principles that guide the ethical practice of online studies were followed. RESULTS: Eight hundred and sixteen young people and adults from Lima and Callao (200 men and 616 women; mean age 28.40, SD 7.10) participated. The results show a one-dimensional model with satisfactory goodness-of-fit indices: χ2 (9)=52.00; CFI=0.99; RMSEA=0.09 [0.07, 0.12]; WRMR=0.85. The λ of the model were higher than 0.50 and the reliability had an excellent value (ω=0.90). Likewise, the convergent and discriminant validity is evident between PRE-COVID-19 and measures of anxiety, well-being and self-reported health. CONCLUSION: The results indicate that the PRE-COVID-19 is a valid and reliable instrument to measure concern about the spread of COVID-19 and the emotional impact on people.

Introducción: La COVID-19 ha generado preocupación por el contagio, sobre todo en el personal de salud que está en primera línea. Objetivo: Analizar las evidencias de validez de contenido, estructura interna y confiabilidad de una medida de preocupación por el contagio de la COVID-19 en internos peruanos. Métodos: Estudio transversal con diseño instrumental. La escala fue administrada mediante un cuestionario virtual y posteriormente distribuida a través de las redes sociales a 275 internos (58 varones y 217 mujeres) como resultado de un muestreo no probabilístico intencional, cuyas edades estuvieron comprendidas entre 19 y 40 años. Resultados: Los valores del coeficiente V de Aiken fueron favorables para todos los ítems. El análisis factorial exploratorio indicó la existencia de un solo factor. El análisis factorial confirmatorio sugirió eliminar los ítems 1 y 7. La confiabilidad de la escala fue buena y se calculó con el coeficiente α de Cronbach = 0,872. Conclusiones: La escala de preocupación por el contagio de la COVID-19 en internos peruanos es una medida breve válida y confiable que puede ser utilizada para fines de investigación y rol profesional(AU)
Introduction: The COVID-19 pandemic has created concern over contagion, particularly among front-line healthcare workers. Objective: Analyze the evidence of content validity, internal structure and reliability of a scale measuring concern over contagion with COVID-19 among Peruvian interns. Methods: An instrumental cross-sectional study was conducted. The scale was applied via a virtual questionnaire and then distributed over the social networks to 275 interns (58 male and 217 female) selected by intentional nonprobability sampling whose age ranged from 19 to 40 years. Results: Aiken's V coefficient values were favorable for all items. Exploratory factor analysis showed the presence of a single factor. Confirmatory factor analysis suggested deletion of items 1 and 7. Reliability of the scale proved to be good. It was estimated with a Cronbach's α coefficient of 0.872. Conclusions: The scale measuring concern over contagion with COVID-19 among Peruvian interns is brief, valid and reliable, and may be used for research and professional role purposes(AU)
