Abstract

Environmental or genetic influences, or both could account for the increased risk of divorce among the offspring of separated parents. Previous studies have used covariates to statistically control for confounds, but the present research is the first genetically informed study of the topic. The investigation used the Children of Twins Design with twins, their spouses, and their young adult offspring (n = 2,310) from the Australian Twin Registry to test whether selection on the basis of genetic or shared environment factors accounted for part of the inter-generational association. The analyses also controlled for measured characteristics of both parents. The results suggest that both environmentally mediated and genetic risk account for the intergenerational transmission, supporting the roles of both selection and causation.

摘要

环境影响或遗传影响,或两者兼而有之,都可能是父母离异的后代离婚风险增加的原因。以往的研究使用协变量来对混杂因素进行统计学控制,但本研究是该主题的第一项基于遗传学的研究。该调查采用双胞胎子代设计,研究对象包括来自澳大利亚双胞胎登记处的双胞胎、他们的配偶以及他们的成年子女(n = 2310),以检验基于遗传或共同环境因素的选择是否是代际关联的部分原因。分析还对父母双方的可测量特征进行了控制。结果表明,环境介导的风险和遗传风险都对代际传递有影响,这支持了选择和因果关系的作用。
