Prior work indicates that aspects of interpersonal relationships are heritable, including negativity within parent-adolescent relationships as well as romantic relationships during adulthood. There have not, however, been systematic studies to disentangle genetic and environmental influences on relationship dynamics with parents as they relate to romantic partner relationship dynamics. Thus, the present study examined genetic and environmental influences on associations between parent-adolescent conflict and young adult reports of negativity with a romantic partner using a longitudinal twin/sibling design. We found that genetic, shared, and nonshared environmental factors contributed to conflict in parent-adolescent relationships and that genetic and nonshared environmental factors uniquely contributed to negativity in the romantic partnership during young adulthood. The longitudinal association between parent-adolescent conflict and romantic relationship conflict was explained entirely by genetic influences shared by the 2 constructs. These findings have implications for understanding interpersonal functioning across different relationship types, spanning multiple developmental periods.

先前的研究表明，人际关系的某些方面是可遗传的，包括亲子关系中的消极方面以及成年期的浪漫关系。然而，对于父母与浪漫伴侣关系动态相关的亲子关系动态，还没有进行系统的研究来区分遗传和环境的影响。因此，本研究使用纵向双胞胎/兄弟姐妹设计，考察了亲子冲突与青少年时期报告的与浪漫伴侣关系的消极性之间的关联的遗传和环境影响。我们发现，遗传、共享和非共享环境因素促成了亲子关系中的冲突，而遗传和非共享环境因素则独特地促成了青少年时期浪漫关系中的消极性。亲子冲突与浪漫关系冲突之间的纵向关联完全由这两个结构的共同遗传影响所解释。这些发现对于理解不同关系类型和多个发展阶段的人际功能具有重要意义。（APA 版权所有，2019）。
