我们测试了差异易感性假设的起源家庭的相互作用和随后的行为与浪漫的合作伙伴之间的联系。在一项正在进行的纵向研究（N = 352）中，观察到焦点或目标参与者（G2）在青春期与父母（G1）互动，并在成年后再次与他们的浪漫伴侣互动。独立的观察员评价积极的参与和敌意的G1和G2在结构化的互动任务。我们通过总结G2在5个基因（5-羟色胺转运蛋白基因[连锁多态性]，5-HTT;锚蛋白重复和激酶结构域包含1个基因/多巴胺受体D2基因，ANKK 1/DRD 2;多巴胺受体D4基因，DRD 4;多巴胺主动转运蛋白基因，DAT;和儿茶酚-O-甲基转移酶基因，COMT）中多态性的等位基因变异，创建了一个假设遗传可塑性指数。与差异易感性假说相一致，在青春期暴露于更多敌意和积极参与的父母行为的G2，如果他们在遗传可塑性指数上得分较高，则对浪漫伴侣更具敌意或积极参与。简而言之，无论是好是坏，遗传因素都会调节早期家庭经历与未来浪漫关系行为之间的联系。
We tested the differential susceptibility hypothesis with respect to connections between interactions in the family of origin and subsequent behaviors with romantic partners. Focal or target participants (G2) in an ongoing longitudinal study (N = 352) were observed interacting with their parents (G1) during adolescence and again with their romantic partners in adulthood. Independent observers rated positive engagement and hostility by G1 and G2 during structured interaction tasks. We created an index for hypothesized genetic plasticity by summing G2's allelic variation for polymorphisms in 5 genes (serotonin transporter gene [linked polymorphism], 5-HTT; ankyrin repeat and kinase domain containing 1 gene/dopamine receptor D2 gene, ANKK1/DRD2; dopamine receptor D4 gene, DRD4; dopamine active transporter gene, DAT; and catechol-O-methyltransferase gene, COMT). Consistent with the differential susceptibility hypothesis, G2s exposed to more hostile and positively engaged parenting behaviors during adolescence were more hostile or positively engaged toward a romantic partner if they had higher scores on the genetic plasticity index. In short, genetic factors moderated the connection between earlier experiences in the family of origin and future romantic relationship behaviors, for better and for worse.
