Understanding the homogeneity of peer groups requires identification of peer groups and consideration of influence and selection processes. Few studies have identified adolescent peer groups, however, or examined how they become homogeneous. This study used social network analysis to identify peer groups (cliques), clique liaisons, and isolates among adolescents in 5 schools at 2 data collection rounds (N = 926). Cigarette smoking was the behavior of interest. Influence and selection contributed about equally to peer group smoking homogeneity. Most smokers were not peer group members, however, and selection provided more of an explanation than influence for why isolates smoke. The results suggest the importance of using social network analysis in studies of peer group influence and selection.
了解同龄人群体的同质性需要识别同龄人群体，并考虑影响和选择过程。然而，很少有研究识别出青少年同龄人群体，或者研究它们是如何变得同质化的。本研究使用社会网络分析来识别5所学校的青少年在两轮数据收集（N = 926）中的同龄人群体（小团体）、小团体联络人及孤立者。吸烟是研究感兴趣的行为。影响和选择对同龄人群体吸烟同质性的贡献大致相同。然而，大多数吸烟者并非同龄人群体成员，对于孤立者吸烟的原因，选择比影响提供了更多解释。结果表明在同龄人群体影响和选择研究中使用社会网络分析的重要性。
