  1. Factor loadings are completely standardized estimates. All factor loadings were statistically significant except those marked with a. G general factor, g group factor, λ factor loading, ECV explained common variance, α cronbach’s alpha, ωT omega total, and ωH omega hierarchical, ωS omega subscale. †p < 0.001
