Research has long demonstrated that siblings are similar in their alcohol use, however much of this work relies on cross-sectional samples or samples of adolescents alone and/or exclusive focus on older siblings' impact on younger siblings. Using a three time-point design from early adolescence to early adulthood (M ages = 14.9, 18.3, and 22.4 years, respectively; 55% female; 54% European ancestry, 38% Asian ancestry), we evaluated the prospective older and younger sibling influences on alcohol use across time (N = 613 sibling pairs; 35% sisters, 26% brothers, 39% mixed-gender; average age difference = 2.34 years; 34% full-biological siblings, 46% genetically-unrelated adopted siblings, 20% pairs where one child was the biological offspring of parents and the other was adopted). The results from both the traditional and random-intercept cross-lagged panel analyses showed that older siblings' alcohol use predicted younger siblings' alcohol use across each developmental transition and across a variety of sibling contexts (e.g., gender composition, age difference, genetic relatedness). On the other hand, younger siblings' alcohol use only predicted older siblings' alcohol use when siblings were close in age (1.5 years or less) and under conditions of high sibling companionship. These results add to a body of literature illustrating how both older and younger siblings are important socializing agents of adolescent and early adult alcohol use. Assessing or co-treating siblings for alcohol problems may be an important add-on to existing adolescent and early adult alcohol prevention and intervention programs.
研究长期以来表明，兄弟姐妹在饮酒方面具有相似性，然而，这项工作大多依赖于横断面样本或仅针对青少年的样本，以及/或者仅关注哥哥姐姐对弟弟妹妹的影响。我们采用了从青少年早期到成年早期的三次时间点设计（M 年龄分别为 14.9、18.3 和 22.4 岁；55%为女性；54%为欧洲血统，38%为亚洲血统），评估了哥哥姐姐对酒精使用的前瞻性影响，跨越时间（N=613 对兄弟姐妹；35%为姐妹，26%为兄弟，39%为混合性别；平均年龄差异为 2.34 岁；34%为全生物学兄弟姐妹，46%为遗传上无关联的收养兄弟姐妹，20%为一对孩子中一个是父母的亲生子女，另一个是收养的）。传统和随机截距交叉滞后面板分析的结果均表明，哥哥姐姐的饮酒行为会预测每个发展阶段以及各种兄弟姐妹环境（例如，性别构成、年龄差异、遗传关系）中弟弟妹妹的饮酒行为。另一方面，只有当兄弟姐妹年龄相近（1.5 岁或更小时）并且兄弟姐妹关系密切时，弟弟妹妹的饮酒行为才会预测哥哥姐姐的饮酒行为。这些结果增加了一个文献体系，说明了哥哥姐姐和弟弟妹妹都是青少年和成年早期酒精使用的重要社会化因素。评估或共同治疗兄弟姐妹的酒精问题可能是现有青少年和成年早期酒精预防和干预计划的一个重要补充。
