Note(s): 1-4-2 structure = 24 items served as indicators of their respective eight first-order latent factors, which in turn were paired to form four second-order latent factors, ultimately measuring an higher-order latent construct; 1-0-8 structure = a general factor directly encompassed the eight components, without an intermediate level; 0-4-2 structure = the eight components were paired under four higher-order latent variables, but without an overarching general factor; 0-0-8 structure = each of the eight first-order latent variables correlated with the others, without any higher-order factor. Δχ² and ΔCFI indicate differences with respect to the baseline measurement model with a 1-4-2 structure; differences are reported as absolute values. ***p < 0.001
