This study investigated (1) reciprocal links among parental psychological control, peer rejection, and adolescent externalizing (aggressive and rule-breaking behaviour), and (2) the moderating effect of an adolescent genetic factor (biologically informed polygenic score for dopamine signalling). Three-year longitudinal data from 1,116 adolescents (51% boys; M age = 13.79) and their parents included psychological measures (adolescent-reported psychological control, peer-reported rejection, and parent-reported aggressive and rule-breaking behaviour). Cross-lagged analyses showed bidirectional effects between psychological control and both aggressive and rule-breaking behaviour and a unidirectional effect of peer rejection on both forms of problem behaviour over time. Multigroup structural equation modelling revealed genetic moderation only for rule-breaking behaviour: for adolescents with intermediate levels of dopamine signalling significant environmental effects were present, whereas adolescent effects of rule-breaking behaviour on psychological control were significant for adolescents with both intermediate and high profiles and effects on peer rejection only for adolescents with high dopamine profiles. Statement of contribution What is already known on this subject? Parental psychological control is related to adolescent externalizing problems. Experiencing peer rejection reinforces aggressive and rule-breaking behaviour. Single-gene studies show that dopaminergic genes influence externalizing problems directly or in interaction with the environment. What does this study add? Parental psychological control and adolescent aggressive and rule-breaking behaviour exacerbate one another longitudinally. Longitudinal associations between peer rejection and both subtypes of externalizing behaviour are unidirectional. With a polygenic approach, dopaminergic moderation is present for rule-breaking behaviour only.
（1）父母心理控制、同伴拒绝与青少年外化问题（攻击性行为和违规行为）之间的相互联系；（2）青少年遗传因素（多巴胺信号传导的生物学知情多基因评分）的调节作用。来自1116名青少年（51%为男孩；平均年龄 = 13.79岁）及其父母的三年纵向数据包括心理测量指标（青少年自我报告的心理控制、同伴报告的拒绝，以及父母报告的攻击性行为和违规行为）。交叉滞后分析表明，心理控制与攻击性行为和违规行为之间存在双向影响，且随着时间推移，同伴拒绝对这两种问题行为均有单向影响。多组结构方程模型显示，遗传因素仅对违规行为有调节作用：对于多巴胺信号传导处于中等水平的青少年，存在显著的环境影响，而违规行为对心理控制的影响在多巴胺信号传导处于中等和高水平的青少年中均显著，且仅对多巴胺信号传导处于高水平的青少年的同伴拒绝有影响。贡献声明关于该主题已知的信息有哪些？父母心理控制与青少年外化问题有关。经历同伴拒绝会强化攻击性行为和违规行为。单基因研究表明，多巴胺能基因直接或与环境相互作用影响外化问题。本研究增加了哪些内容？父母心理控制与青少年攻击性行为和违规行为在纵向层面上相互加剧。同伴拒绝与两种外化行为亚型之间的纵向关联是单向的。采用多基因方法，多巴胺能调节仅存在于违规行为中。
