The main aim of the study was to test the moderating effect of two genetic polymorphisms, one in the dopamine D2 receptor gene (DRD2) and one in the mu-opioid receptor gene (OPRM1), on the link between parental rule-setting and adolescent alcohol use.
A total of 214 adolescents (M(age )=13.7, 44.9% male) provided saliva samples and completed survey items describing alcohol use and parental rule-setting.
Findings indicated that alcohol-specific parental rule-setting was more robustly associated with alcohol use for adolescents with the DRD2 A1 risk allele and for those with the OPRM1 G-allele.
This study replicates the interaction between parental rule-setting and the DRD2 risk allele on adolescent alcohol use and extends the literature by demonstrating the moderating effects of the OPRM1 risk allele on the link between parental rule-setting and adolescent alcohol use.
本研究的主要目的是检验两种遗传多态性（一种在多巴胺 D2 受体基因（DRD2）中，一种在μ-阿片受体基因（OPRM1）中）对父母规则制定与青少年饮酒之间关系的调节作用。
共有 214 名青少年（M（年龄）=13.7，44.9%为男性）提供了唾液样本，并完成了描述饮酒和父母规则制定的调查项目。
研究结果表明，对于携带 DRD2 A1 风险等位基因的青少年和携带 OPRM1 G-等位基因的青少年，特定于酒精的父母规则制定与饮酒之间的关系更为密切。
本研究复制了父母规则制定与 DRD2 风险等位基因对青少年饮酒的相互作用，并通过证明 OPRM1 风险等位基因对父母规则制定与青少年饮酒之间关系的调节作用，扩展了文献。
