背景：尽管理论和经验支持母亲控制和儿童焦虑之间的关联，很少有研究探讨这种关联的起源。此外，没有一个在遗传信息设计中使用母亲控制的绝对评分。这项研究解决了三个问题：1）经历过母亲控制的儿童是否比那些没有经历过母亲控制的儿童报告更高的焦虑水平？2)遗传和环境因素在多大程度上影响母亲的控制和孩子的焦虑？3)遗传和环境因素在多大程度上影响儿童焦虑和母亲控制之间的联系？方法：530名8岁儿童（来自265对双胞胎）和他们的母亲参加了一个“蚀刻素描”的任务，从母亲控制的评级。儿童评定他们的焦虑使用屏幕为儿童焦虑相关的情绪disorders.Results：儿童谁经历了母亲的行为被评为“极端控制”报告的焦虑水平高于那些谁没有。母亲的控制是高度遗传的（A = 0.63），高自评焦虑不那么（h2（g）= 0.36）。高儿童焦虑和产妇控制之间的重叠主要是由于共享的遗传factors.Conclusions：这些结果表明，产妇控制很可能已引起儿童高水平的焦虑。
Background:Despite theoretical and empirical support for an association between maternal control and child anxiety, few studies have examined the origins of this association. Furthermore, none use observer-ratings of maternal control within a genetically informative design. This study addressed three questions: 1) do children who experience maternal control report higher anxiety levels than those who do not?; 2) to what extent do genetic and environmental factors influence maternal control and child anxiety?; 3) to what extent do genetic and environmental factors influence the associations between child anxiety and maternal control?Method:Five hundred and thirty 8-year-old children (from 265 twin pairs) and their mothers were observed participating in an 'etch-a-sketch' task from which maternal control was rated. Children rated their anxiety using the Screen for Child Anxiety Related Emotional Disorders.Results:Children who experienced maternal behaviour rated as 'extreme control' reported higher anxiety levels than those who did not. Maternal control was highly heritable (A = .63), high self-rated anxiety less so (h2(g) = .36). The overlap between high child anxiety and maternal control was primarily due to shared genetic factors.Conclusions:These results suggest that maternal control is likely to have been elicited by children with high levels of anxiety.
