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.
