在一个具有代表性的13岁双胞胎大样本中，在注意力的客观衡量标准以及父母和老师对多动症的评级上，同卵双胞胎比同性异卵双胞胎更相似。对确认的和未确认的同卵双胞胎的比较表明，当双胞胎被认为是“同卵”而不是“异卵”时，父母和老师对双胞胎的评价更相似。在考虑到这种刻板印象后，遗传效应约占多动症和注意力不集中的可解释差异的一半。来自男女混合配对的数据不支持男性多动症的双阈值遗传解释。不良的家庭因素与多动症之间的联系很弱。围产期逆境与以后的多动无关。
In a large representative sample of 13-year-old twins, monozygotic pairs were more alike than same-sex dizygotic pairs on objective measures of attentiveness and on parent and teacher ratings of hyperactivity. Comparison of recognized and unrecognized monozygotic pairs indicated that parents and teachers rated twins more similarly when the twins were perceived as "identical" rather than "non-identical". After allowing for this stereotyping, genetic effects accounted for approximately half of the explainable variance of hyperactivity and inattentiveness. Data from mixed-sex pairs did not support a 2-threshold genetic explanation for the male excess of hyperactivity. The link between adverse family factors and hyperactivity was weak. Perinatal adversity was not related to later hyperactivity.
