Note. The general factor in the unidimensional and bifactor models is labelled λ_G, loadings for the correlated factors model are labelled λ_DIS, λ_AGG, λ_SUB, mimicking the item-based subfactors of the ESI-BF, and loadings for the two residual factors in the bifactor model are labelled λ_RAGG, and λ_RSUB. Residual variances are labelled Θ, with standard errors shown in parentheses. Values of 0 are fixed and not estimated, and dashes denote facets omitted from the model
