As stated above, A and C influences were significantly correlated across SELF and PEER (rA=0.83 and rC=1.00 in Figure 2A and Figure 2B, respectively), and the correlated common factors accounted for the majority of A and C variance. However, phenotype- and time-specific factors also accounted for a proportion of the variance (e.g., path estimates of 0–0.41 for SELF in Figure 2A; see Supplementary Tables 2 and 3). In all but two cases (specific A influences on PEER1 and specific C influences on PEER4), the majority of genetic and shared environmental variance for SELF and PEER was derived from correlated common factors. Phenotype- and time-specific A and C factors accounted for 6% or less of the total phenotypic variance.
