Social norms positively predict college students' alcohol use, but it is critical to explore heterogeneity in these patterns to identify which students are most susceptible to normative influences. The current study explored the nature of drinking norms within college student peer sport clubs. We examined the association between self-reported alcohol use (i.e., number of drinks in a typical week) and perceived descriptive/injunctive norms as an indicator of norm adherence and then tested moderating effects of social constructs related to the group: Social identification with one's team, along with social network-derived indices of indegree centrality and network density. We sampled members of 35 intact college club sport teams at 3 timepoints across the school year ( = 1,054; 61% female). Multilevel modeling was employed to estimate moderating effects at within-person, between-person, and between-groups levels. Initial analyses revealed that perceived group norms predicted self-reported alcohol use, and that teams approached consensus on the groups' drinking norms over time. Several significant time-varying moderation patterns were uncovered. At timepoints when students identified more strongly with their team (relative to person-mean levels), they more readily adhered to perceived descriptive and injunctive team drinking norms. Students also adhered more closely to these perceived team drinking norms at timepoints when students were nominated as having relatively lower indegree centrality. Cross-level interactions revealed that neither network density nor team sex moderated these associations. Taken together, the current findings advance our understanding of group processes that may produce more salient social influences on students' alcohol use behaviors within proximal peer groups.

社会规范对大学生饮酒行为有积极的预测作用，但关键是要探讨这些模式的异质性，以确定哪些学生最容易受到规范的影响。本研究探讨了大学生同伴体育俱乐部内饮酒规范的性质。我们考察了自我报告的饮酒量（即典型周的饮酒量）与感知的描述性/指令性规范之间的关系，将其作为规范遵守的指标，然后测试了与群体相关的社会结构的调节作用：对团队的社会认同，以及社会网络衍生的入度中心性和网络密度的指标。我们在整个学年的 3 个时间点上对 35 个完整的大学生俱乐部运动队的成员进行了抽样（n=1054；61%为女性）。采用多层模型来估计个体内、个体间和群体间的调节效应。初步分析表明，感知的群体规范预测了自我报告的饮酒量，并且随着时间的推移，团队对群体饮酒规范的共识逐渐达成。发现了几个显著的时变调节模式。当学生相对于个人平均水平更强烈地认同自己的团队时（相对于个人平均水平），他们更愿意遵守感知到的描述性和指令性团队饮酒规范。当学生被提名具有相对较低的入度中心性时，他们也更紧密地遵守这些感知到的团队饮酒规范。交叉水平的交互作用表明，网络密度和团队性别都没有调节这些关联。总之，目前的研究结果增进了我们对群体过程的理解，这些过程可能会在近邻同伴群体中对学生的饮酒行为产生更突出的社会影响。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
