An Adoption Study of the Etiology of Teacher and Parent Reports of Externalizing Behavior Problems in Middle Childhood.
Deater-Deckard, Kirby; Plomin, Robert
Child Development, v70 n1 p144-54 Jan-Feb 1999
Explored aggression and delinquency in unrelated adoptive sibling pairs and biologically-related sibling pairs in the Colorado Adoption Project at 7, 9, 10, 11, and 12 years. Found that boys and adopted children were higher in externalizing behavior problems than girls and biologically related pairs. Sex differences in delinquency were more pronounced in adoptive than in nonadoptive families. (KB)
