从双胞胎研究的概括依赖于这样的假设，即发展所研究的障碍的可能性受到双胞胎和单胞胎相似因素的影响。本研究探讨的影响，产前和围产期因素对父母的行为问题的报告，在1832双胞胎，并比较注意力问题，内化和外化行为的双胞胎与723名儿童和青少年从一般人群样本的水平。相对出生体重和出生顺序对双胞胎注意力问题水平的适度影响并没有导致双胞胎和普通人群样本之间的显着差异。注意力问题和外化行为的水平是相似的，有一个适度的年龄依赖性差异的内化行为。一个增加的方差被发现在双胞胎的外化行为。
Generalization from twin studies relies on the assumption that liability to develop the disorder which is studied is influenced by similar factors in twins and singletons. The present study examines the impact of pre- and perinatal factors on parental reports of behaviour problems in 1832 twins, and compares level of attention problems, internalizing and externalizing behaviour in the twins with 723 children and adolescents from a general population sample. The modest influence of relative birth weight and birth order on level of attention problems in twins did not contribute to significant differences between twins and the general population sample. The levels of attention problems and externalizing behaviour was similar and there was a modest age dependent difference in internalizing behaviour. An increased variance was found for externalizing behaviour in twins.
