Several strengths of the present study are noteworthy. It includes the first tests for genetically influenced child effects on neglect and sexual maltreatment known to the authors. The analyses benefited from a genetically informative subsample of the largest nationally representative study of adolescent health ever conducted in the United States. Both twin and full sibling pairs were included, allowing us to estimate the magnitude of twin environmental influences. Also, the use of child report of maltreatment ensures that C and T are not overestimated due to rater biases.
