The present study examined the role of gene-environment correlations in the association between parent-child similarity in negative emotionality and addressed whether it is mediated by negative or warm parenting, assessed when children were between 7 and 15 years old. Participants included 843 children from 493 families in the Colorado Adoption Project (48% female, 95% White, 5% Hispanic). Results indicated that passive rGE may contribute to associations between parents' and children's negative emotionality assessed at age 16 years. Additionally, negative parenting partially mediated the association between biological mothers' negative emotionality and children's negative emotionality. Results were not consistent with evocative rGE. Studies of parent-child similarity should consider plausible alternative hypotheses, such as gene-environment correlation, rather than assuming environmental mediation.
本研究考察了基因-环境相关性在消极情绪方面亲子相似性关联中的作用，并探讨了其是否由消极或温暖型养育方式介导，这些养育方式是在孩子7至15岁时进行评估的。参与者包括来自科罗拉多收养项目中493个家庭的843名儿童（48%为女性，95%为白人，5%为西班牙裔）。结果表明，被动的基因-环境相关性可能导致16岁时评估的父母与孩子消极情绪之间的关联。此外，消极养育方式部分介导了亲生母亲消极情绪与孩子消极情绪之间的关联。结果与唤起性基因-环境相关性不一致。关于亲子相似性的研究应考虑合理的替代假设，如基因-环境相关性，而不是假设环境介导作用。
