The present study investigated social influence and selection explanations for the association between frequency of heavy drinking and perceived peer alcohol involvement in emerging and early adulthood. Participants were 489 young adults recruited from a university setting who were taking part in an 11-year longitudinal study, which includes 6 waves of data. Piecewise latent growth curve analyses indicated that patterns of change from ages 18 to 30 for both frequency of heavy drinking and perceived peer alcohol involvement are best represented by two distinct developmental periods (i.e., college and post-college years). Several models were compared to identify a framework that yielded the best estimates of influence and selection effects. Evidence suggests that selection mechanisms may best account for the relation between frequency of heavy drinking and perceived peer alcohol involvement especially during the post-college years.
本研究调查了在青少年晚期和成年早期，重度饮酒频率与感知到的同伴饮酒参与度之间关联的社会影响和选择解释。参与者是从一所大学招募的489名年轻成年人，他们参与了一项为期11年的纵向研究，该研究包括6次数据收集。分段潜在增长曲线分析表明，18岁至30岁期间重度饮酒频率和感知到的同伴饮酒参与度的变化模式，最好由两个不同的发展阶段（即大学阶段和大学毕业后阶段）来表示。比较了几个模型，以确定一个能对影响和选择效应做出最佳估计的框架。有证据表明，选择机制可能最能解释重度饮酒频率与感知到的同伴饮酒参与度之间的关系，尤其是在大学毕业后阶段。
