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 (N = 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.

扩大对大学俱乐部运动队感知饮酒规范的遵守的群体和个人的动态特征：纵向多层次调查。

社会规范积极预测大学生的酒精使用，但探索这些模式的异质性以确定哪些学生最容易受到规范影响至关重要。目前的研究探讨了大学生同伴运动俱乐部饮酒规范的性质。我们检查了自我报告的酒精使用量（即典型一周内的饮酒量）与感知描述性/禁令性规范之间的关联，作为规范遵守的指标，然后测试了与该群体相关的社会结构的调节作用：与一个人的社会认同团队，以及社交网络衍生的度中心度和网络密度指数。我们在整个学年的 3 个时间点对 35 个完整的大学俱乐部运动队的成员进行了抽样调查（N = 1,054；61% 为女性）。采用多级建模来估计人内、人际和组间水平的调节作用。初步分析显示，感知到的群体规范可以预测自我报告的酒精使用情况，并且随着时间的推移，团队就群体的饮酒规范达成了共识。发现了几个重要的时变缓和模式。在学生更强烈地认同他们的团队（相对于个人平均水平）的时间点，他们更容易遵守感知到的描述性和禁令性团队饮酒规范。在学生被提名为具有相对较低的度中心性的时间点，学生们也更密切地遵守这些感知到的团队饮酒规范。跨层次的互动表明，网络密度和团队性别都没有调节这些关联。综合起来，目前的研究结果促进了我们对团体过程的理解，这些过程可能对邻近同龄群体中学生的酒精使用行为产生更显着的社会影响。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
