TY - JOUR PY - 1999// TI - Sex differences in the etiology of aggressive and nonaggressive antisocial behavior: results from two twin studies JO - Child development A1 - Eley, Thalia C. A1 - Lichtenstein, Paul A1 - Stevenson, J. SP - 155 EP - 168 VL - 70 IS - 1 N2 - Recent theory and results from twin and adoption studies of children and adolescents suggest greater genetic influence on aggressive as compared to nonaggressive antisocial behavior. In addition, quantitative or qualitative differences in the etiology of these behaviors in males and females have been indicated in the literature. The Child Behavior Checklist was completed by the parents of 1022 Swedish twin pairs aged 7-9 years and of 501 British twin pairs aged 8-16 years. Genetic factors influenced aggressive antisocial behavior to a far greater extent than nonaggressive antisocial behavior, which was also significantly influenced by the shared environment. There was a significant sex difference in the etiology of nonaggressive antisocial behavior. Bivariate analyses supported the conclusion that the etiologies of aggressive and nonaggressive antisocial behavior differ for males and females.
