Excessive alcohol consumption is related to adverse physical and social consequences. Research shows an individual's own drinking motives (reasons for drinking alcohol) are linked to his or her specific drinking outcomes in a theoretically expected manner. Romantic couples often engage in a "drinking partnership," where partners reciprocally influence each other's drinking. Though alcohol consumption partner effects have been studied, partner effects of drinking motives on an individual's alcohol consumption have not been investigated in romantic couples. We investigated this topic. Romantic couples ( = 203) were assessed once weekly for four weeks using self-report questionnaires. Participants were on average 22.7 years old = 5.5) and were in their relationship an average of 2.3 years = 2.4). Actor-partner interdependence models using multilevel path-analysis with indistinguishable dyads were conducted, with each motive predicting drinking quantity and frequency. There were significant actor effects for social and enhancement motives; moreover, changes in a partner's enhancement and social motives predicted change in the individual's drinking quantity during any given week, but only averaged partners' enhancement motives predicted the individual's drinking frequency. Coping-with-anxiety motives had significant actor effects when predicting averaged quantity and frequency; moreover, changes in partners' coping-with-anxiety motives predicted changes in drinking quantity. Enhancement and social motives of the partner influenced the drinking quantity and frequency of the actor by way of influencing the actor's enhancement and social motives. Intervention efforts targeting both members of a romantic dyad on their reasons for drinking should be tested for preventing escalations in either member's drinking behavior.

过量饮酒会导致身体和社交方面的不良后果。研究表明，个体自身的饮酒动机（饮酒原因）以理论上可预期的方式与其特定的饮酒结果相关。情侣通常会形成“饮酒伴侣关系”，伴侣之间会相互影响彼此的饮酒行为。虽然已经研究了酒精消费的伴侣效应，但在浪漫伴侣中，饮酒动机对个体饮酒的伴侣效应尚未得到调查。我们调查了这个话题。使用自我报告问卷，对 203 对浪漫伴侣进行了为期四周、每周一次的评估。参与者的平均年龄为 22.7 岁（标准差=5.5），恋爱关系的平均持续时间为 2.3 年（标准差=2.4）。使用不可区分的对偶多层次路径分析进行了演员-伙伴相互依赖模型，每个动机都预测了饮酒量和饮酒频率。社交动机和增强动机具有显著的演员效应；此外，伴侣的增强动机和社交动机的变化可以预测个体在任何给定周内的饮酒量变化，但只有伴侣的增强动机的平均值可以预测个体的饮酒频率。当预测平均饮酒量和频率时，应对焦虑动机具有显著的演员效应；此外，伴侣应对焦虑动机的变化可以预测饮酒量的变化。伴侣的增强动机和社交动机通过影响演员的增强动机和社交动机来影响演员的饮酒量和频率。应该测试针对浪漫伴侣关系中的双方成员的干预措施，以防止任何一方成员的饮酒行为升级。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
