Behaviors, traits and characteristics are transmitted from parents to offspring because of complex genetic and non-genetic processes. We review genetic and non-genetic mechanisms of intergenerational transmission of psychopathology and parenting and focus on recent methodological advances in disentangling genetic and non-genetic factors. In light of this review, we propose that future studies on intergenerational transmission should aim to disentangle genetic and non-genetic transmission, take a long-term longitudinal perspective, and focus on paternal and maternal intergenerational transmission. We present four large longitudinal cohort studies within the Consortium on Individual Development, which together address many of these methodological challenges. These four cohort studies aim to examine the extent to which genetic and non-genetic transmission from the parental generation shapes parenting behavior and psychopathology in the next generation, as well as the extent to which self-regulation and social competence mediate this transmission. Conjointly, these four cohorts provide a comprehensive approach to the study of intergenerational transmission.

由于复杂的遗传和非遗传过程，行为，特质和特征从父母传给后代。我们审查了心理病理学和育儿的代际传播的遗传和非遗传机制，并着重探讨了解决遗传和非遗传因素的最新方法学进展。有鉴于此，我们建议对世代间传播的未来研究应旨在消除遗传和非遗传传播，采取长期的纵向观点，并着重于父辈和母亲的代际传播。我们在个人发展联盟中提出了四项大型纵向队列研究，这些研究共同解决了许多方法论难题。这四项队列研究旨在研究父母一代遗传和非遗传传播对下一代父母行为和心理病理的影响程度，以及自我调节和社会能力介导这种传播的程度。同时，这四个队列为研究代际传播提供了一种综合方法。
