Structural equation models built based on a priori assumptions on how traits might be related to each other. The models were compared with each other using AIC values of each model. The model set is built from the individual-level covariance matrix acquired from the multivariate mixed-effects model. A small AIC value indicates a better fit of the model compared with a large AIC value. Numbers next to the arrows are standardized factor loadings with standard errors (in brackets) for the effects of the underlying syndrome structure on a particular behaviour. Numbers inside the variable boxes are the variance unexplained by the latent variable (L) with standard errors (in brackets) (models F and G).
