Note. Age centered at 13 and pubertal status centered at 1. Anxiety and depression composites standardized prior to modeling. Squaring the path coefficient provides the measure of genetic and environment al variance as a function of the interaction term (e.g. squaring the A path indicates heritability as a function of the moderator). SE in parenthesis. p < 0.05 = *, p < 0.01 = **, p < 0.001 = ***.
