青少年早期饮酒是一项重大的公共卫生挑战。如果没有关于同龄人和饮酒之间因果关系的明确指导，青少年酒精干预可能是不完整的。本研究的目的是理清与青少年友谊和饮酒之间的动态相互作用相关的选择和影响效应。该研究分析了 Add Health 的数据，这是一项针对 1995 年至 1996 年间就读的七年级至十一年级美国学生的纵向调查。使用基于随机参与者的模型来模拟饮酒和友谊关系的共同演化。选择效应在创建具有相似饮酒情况的同伴群体方面发挥着重要作用。饮酒频率相同的两名学生之间的友谊提名的可能性比饮酒频率不同的其他相同学生之间的友谊提名高 3.60 (95% CI: 2.01-9.62) 倍。该模型控制了友谊提名的替代途径，包括互惠、传递性以及年龄、性别和种族/民族的相似性。模拟模型不支持朋友对饮酒行为的显着影响。研究结果表明，同伴选择在青少年朋友的饮酒行为中起着重要作用。我们的模拟结果将有助于利用青少年社交网络特征的青少年酗酒干预措施。
Early adolescent alcohol use is a major public health challenge. Without clear guidance on the causal pathways between peers and alcohol use, adolescent alcohol interventions may be incomplete. The objective of this study is to disentangle selection and influence effects associated with the dynamic interplay of adolescent friendships and alcohol use. The study analyzes data from Add Health, a longitudinal survey of seventh through eleventh grade U.S. students enrolled between 1995 and 1996. A stochastic actor-based model is used to model the co-evolution of alcohol use and friendship connections. Selection effects play a significant role in the creation of peer clusters with similar alcohol use. Friendship nominations between two students who shared the same alcohol use frequency were 3.60 (95% CI: 2.01-9.62) times more likely than between otherwise identical students with differing alcohol use frequency. The model controlled for alternative pathways to friendship nomination including reciprocity, transitivity, and similarities in age, gender, and race/ethnicity. The simulation model did not support a significant friends’ influence effect on alcohol behavior. The findings suggest that peer selection plays a major role in alcohol use behavior among adolescent friends. Our simulation results would lend themselves to adolescent alcohol abuse interventions that leverage adolescent social network characteristics.
