Psychometric Properties of an Adapted Instrument Measuring Stress Specific to COVID-19 in Nurses

Background and Purpose: Several studies have used an adapted measure of stress related to COVID-19, although the psychometric properties of the tool are unknown. The purpose of this study was to evaluate the psychometric properties of an adapted measure in nurses. Methods: This was a secondary analysis of 744 nurses using data from a longitudinal study conducted during COVID-19 from May 2020 to May 2022. Results: Exploratory factor analysis using principal axis factoring with oblique rotation resulted in two correlated factors: personal risk and risk to others. The measure had acceptable internal consistency (α =.754 and α =.738 for factors 1 and 2, respectively) and demonstrated criterion validity between several indicators of mental health and well-being. Conclusions: The adapted measure was reliable and valid in nurses working during COVID-19.
