Implication

Exploratory analysis reveals a three-factor model for perceived vulnerability to infectious diseases in a Portuguese sample during COVID-19, indicating higher differentiation.

Key Points

MAIN FINDING: A three-factor model of the perceived vulnerability to disease scale shows improved differentiation during the COVID-19 lockdown.
KEY EVIDENCE: Analysis of data from 1203 participants using exploratory and confirmatory factor methods supports the new model.
APPROACH: The study utilized a convenience sample and applied exploratory factor analysis and confirmatory factor analysis to assess the scale.
SIGNIFICANCE: The refined scale enhances understanding of how individuals perceive vulnerability to infectious diseases in a pandemic context.
