Note: Variable loadings in a PCA. Varimax rotation with Kaiser normalization. Loadings >0.4 and <−0.4 were considered as salient, and high loadings >0.7 and <−0.7 are indicated in boldface. Communalities indicate a proportion of each variable's variance that can be explained by the principal components. Eigenvalues indicate eigenvalues as obtained by the PCA, whereas percentiles indicate eigenvalues as obtained by parallel analysis with 1000 iterations. *Eigenvalues larger than percentiles.
