父母的批评与青少年后代的内化症状相关。如果相同的基因影响父母和后代的行为，这种相关性可能部分反映了他们的遗传相关性。我们使用双胞胎的孩子的设计，以评估是否父母报告的批评和后代的内化症状仍然相关后，控制共享的基因。为了帮助解释我们的结果和以前的双胞胎研究的结果，我们检查了检测遗传效应的统计能力，并探索了几代人之间可能的因果关系的方向。数据来自两个瑞典双胞胎样本，包括876对成年双胞胎与青少年后代和1030对青少年双胞胎与父母。父母对子女的批评报告与父母和子女对青少年内化症状的报告同时收集。双胞胎子女结构方程模型被用来控制父母的批评和青少年内化之间的代际关联的遗传影响。在控制了遗传因素的影响后，父母的批评与青少年的内化症状有关。在两代人中，没有发现影响表型的共有基因的显著作用，尽管功效分析表明，一些遗传效应可能未被发现。模型无法区分世代之间的非遗传因果效应的方向性。在青少年内化的背景下，父母的批评可能涉及社会心理的家庭过程。未来的研究应设法确定这些过程，并澄清潜在因果效应的方向。
Parental criticism is correlated with internalising symptoms in adolescent offspring. This correlation could in part reflect their genetic relatedness, if the same genes influence behaviours in both parents and offspring. We use a Children-of-Twins design to assess whether parent-reported criticism and offspring internalising symptoms remain associated after controlling for shared genes. To aid interpretation of our results and those of previous Children-of-Twins studies, we examine statistical power for the detection of genetic effects and explore the direction of possible causal effects between generations. Data were drawn from two Swedish twin samples, comprising 876 adult twin pairs with adolescent offspring and 1030 adolescent twin pairs with parents. Parent reports of criticism towards their offspring were collected concurrently with parent and offspring reports of adolescent internalising symptoms. Children-of-Twins structural equation models were used to control for genetic influence on the intergenerational association between parental criticism and adolescent internalising. Parental criticism was associated with adolescent internalising symptoms after controlling for genetic influence. No significant role was found for shared genes influencing phenotypes in both generations, although power analyses suggested that some genetic effects may have gone undetected. Models could not distinguish directionality for non-genetic, causal effects between generations. Parental criticism may be involved in psychosocial family processes in the context of adolescent internalising. Future studies should seek to identify these processes and provide clarity on the direction of potential causal effects.
