同伴关系对大学生的物质使用有影响，但对与大学里有问题的饮酒有关的社交网络特征进行的调查相对较少。本研究调查了大学宿舍网络中声望、扩张性和互惠性的网络特征与饮酒变量之间的关系。1个宿舍的本科生(N=129人；51.9%女性；48.1%非西班牙裔白人；84.5%一年级)报告了他们在过去一个学期中的酒精使用和与酒精相关的问题，并提名了最多10名对他们来说重要的宿舍同龄人。网络自相关模型评估了反映威望(独立性和中间性中心性)、扩张性(外向度)和关系一致性(外向度互惠和外向度互惠)的5个网络变量与酒精使用的3个指标(每周饮酒量、酗酒天数、酗酒次数)之间的关系。网络特征和酒精变量之间的关联的性别调节也被调查了。受控于人口统计和网络自相关的模型。居所网络中较高的外向度和较高的中介中心度分别与酗酒天数和饮酒问题数量显著相关。当酒精使用受到控制时，较高的独立性和较高的介入性中心性与女性更多的酒精问题有关。拥有更高的声望，并表示自己在大学住宿网络中有更多的朋友，可能会传递与酒精相关的风险，有些风险对女性来说更高。
Peer associations are influential for substance use among college students, but relatively few investigations have been conducted on the social network characteristics that are associated with problematic alcohol use in college. This study investigated the association between network characteristics of prestige, expansiveness, and reciprocity and alcohol use variables in a college residence hall network. Undergraduate students in 1 residence hall (N = 129; 51.9% female; 48.1% non-Hispanic White; 84.5% first-year) reported on their alcohol use and alcohol-related problems in the past semester and nominated up to 10 residence hall peers who were important to them. Network autocorrelation modeling evaluated the association between 5 network variables reflecting prestige (indegree and betweenness centrality), expansiveness (outdegree), and relationship agreement (indegree reciprocity and outdegree reciprocity) and 3 indicators of alcohol use (drinks per week, number of heavy drinking days, number of alcohol problems). Moderation by gender of the associations between network characteristics and alcohol variables was also investigated. Models controlled for demographics and network autocorrelation. A higher outdegree and higher betweenness centrality within the residence hall network were significantly related to the number of heavy drinking days and number of alcohol problems, respectively. Higher indegree and higher betweenness centrality were associated with more alcohol problems for women when alcohol use was controlled. Having higher prestige and indicating oneself as having more friends in a college residential network may convey alcohol-related risks, with some risks higher for women.
