F is the loading of each informant rating onto the latent factor; A2, D2 and E2 are standardized components of variance for latent factor; a2 and e2 are standardized components of variance unique to each informant rating; b is the rater contrast effect unique to parent ratings; the lower section of the table gives the proportion of phenotypic variance explained by common/residual genetic (A/a, D) and non-shared environmental (E/e) factors for each informant, where the proportion of variance from the common factor is calculated as the factor loading multiplied by the standardized parameter estimate multiplied by the factor loading (i.e. Common A = F × A2 × F); 95 % confidence intervals in parentheses.
