To this end, in a multi‐group factor analysis in R (R Core Team, 2014), using the following packages: lavaan (Rosseel, 2012), and semTools (Jorgensen et al., 2019), we compared the models assuming a two‐factor structure (positive and negative, with the latter consisting of reversed items; Roberti et al., 2006) across 26 countries and areas (configural invariance), with a model with factor loadings and latent correlations constrained to be equal (metric invariance), and items' intercepts to be the same in all groups (scalar invariance).
