Loadings of genetic variance in each developmental period on the common factor were: adolescence λ12-17 = .35 (SE = 0.64), early adulthood λ18-25 = −.78 (SE = 1.12), adulthood λ26+ = −.97 (SE = 1.36). Residual genetic variances in each developmental period after accounting for the common factor were: adolescence U12-17 = .88 (SE = 1.21), early adulthood U18-25 = .40 (SE = 2.11), adulthood U26+ = .07 (SE = 2.61).
