Within-study replication of nuclear twin family design results, using lifetime reports of parental antisocial behavior

Dimension of Antisocial Behavior	Model	% A	% D	% S	% E	%H (%A+%D)
AGG, lifetime reports of parental AGG	Full ADSE	34.6^*	23.6^*	8.1^ns	33.7^*	58.2^*
	Best-fitting ADE	35.0^*	31.9^*	–	33.1^*	66.9^*
RB, lifetime reports of parental RB	Full ADSE	48.9^*	7.2^ns	19.2^*	24.7^*	56.1^*
	Best-fitting ASE	51.4^*	–	23.0^*	25.6^*	51.4^*

AGG and RB refer to aggressive and non-aggressive antisocial behavior, respectively. Additive genetic, dominant genetic, environmental influences shared between siblings, and non-shared environmental influences are represented with A, D, S, and E, respectively. H refers to the broad or overall heritability of the trait, which is a sum of A and D. A, D, S, and E collectively account for 100 % of the variance in the trait, as do H, S, and E.

indicates that the parameter is significantly greater than zero at p<0.05
