The present study examines the relations between adolescent motherhood and children's behavior, substance use, and internalizing problems in a sample of 1,368 children of 712 female twins from Australia. Adolescent motherhood remained significantly associated with all mental health problems, even when using a quasiexperimental design capable of controlling for genetic and environmental confounds. However, the relation between adolescent motherhood and offspring behavior problems and substance use was partially confounded by family background variables that influence both generations. The results are consistent with a causal relation between adolescent motherhood and offspring mental health problems, and they highlight the usefulness of behavior genetic designs when examining putative environmental risks for the development of psychopathology. The generalizability of these results to the United States, which has a higher adolescent birth rate, is discussed.
本研究在来自澳大利亚的712对女性双胞胎的1368名子女样本中，考察了青少年母亲身份与儿童行为、物质使用及内化问题之间的关系。即使采用能够控制基因和环境混杂因素的准实验设计，青少年母亲身份仍与所有心理健康问题显著相关。然而，青少年母亲身份与后代行为问题及物质使用之间的关系部分受到影响两代人的家庭背景变量的混杂。研究结果与青少年母亲身份和后代心理健康问题之间的因果关系一致，并且突出了行为遗传学设计在研究精神病理学发展的假定环境风险时的有用性。还讨论了这些结果在美国的可推广性，美国的青少年出生率更高。
