Note. a² = additive genetic variance; c² = shared environmental variance; e² = non-shared environmental variance; % of Total Variance = percent of total variance in age 17 behaviors explained by age 14 or age 17 ACE components; Age 14 → Age 17 = proportions of variance in age 17 behaviors explained by age 14 ACE components; Age 17 Residual = proportions of variance in age 17 behaviors not explained by age 14 ACE components. Estimates with confidence intervals that do not include zero are bolded. No variance components differed significantly across females and males when tested in multi-group models.
