Abstract

The striking behavior-genetic findings of the NEAD study of adjustment in adolescence (Reiss, Neiderhiser, Hetherington, & Plomin, 2000) - namely, high heritability (h2), substantial effects of shared family environment (c2) for some traits, and near-vanishing effects of non-shared environment (e2) - were largely confirmed in an independent analysis of the NEAD data. The considerable contribution of monozygotic twins to these results was established, suggesting the importance of nonadditive genetic variance in the adjustment domain. Prenatal maternal effects were tested for, and not found to make a statistically significant contribution to individual differences in adjustment.
