Factor structure and psychometric proprieties of the COVID-19 prevention behaviours (COV19-PB) scale

We sought to test the COVID19-PB scale's psychometric properties and its dimensionality in a sample composed of 1107 Italian adults aged from 18 to 80 years (M = 39.59; SD = 16.36), 75% (n = 830) females, and 25% (n = 277) males. Exploratory, Confirmatory factor analysis and parallel analysis were used to validate the instrument that resulted from the Ebola Virus protective behaviours scale adaptation. Fear of covid-19 and a 1-item level of adherence to the Covid-19 protection scale were used to test the measure's convergent validity. A four-factor structure emerged from exploratory and confirmatory factor analysis: direct avoidance, avoidance of public spaces, avoidance of social interaction, and talking about the virus as protection. COVID-19 PB was a valuable measure to assess individuals' competencies in assuming correct behaviours during the pandemic.
