Using stochastic actor-based models for longitudinal network analysis, this study examines the role of friends' smoking attitudes and behavior for Dutch adolescents' smoking behavior in four secondary schools (N = 875). The data were collected in two waves in two small suburban towns under second graders in 2008 to 2009 by means of a standardized questionnaire. Stochastic actor-based models for longitudinal network analysis can control for friendship selection while examining the effect of friends' attitudes and smoking behavior on the smoking behavior of a student. The findings suggest that friends tend to select each other on similar smoking behavior. Influence of friends' smoking behavior seems to play no role. In one school, an effect of friends' attitudes towards smoking on the smoking behavior is found. The implications for future research are to consider attitudes when examining the influence of friendship network on smoking behavior. The main limitation of this study lies in the limited sample, which makes generalizations to the general population difficult.
本研究使用基于随机主体的模型对纵向网络进行分析，考察了朋友的吸烟态度和行为对荷兰青少年在四所中学吸烟行为的影响（N=875）。这些数据是通过标准化问卷，于 2008 年至 2009 年在两个小型郊区城镇的二年级学生中，分两次收集的。基于随机主体的纵向网络分析模型可以在控制友谊选择的同时，考察朋友的态度和吸烟行为对学生吸烟行为的影响。研究结果表明，朋友之间往往会选择具有相似吸烟行为的人。朋友的吸烟行为似乎没有影响。在一所学校中，发现了朋友对吸烟的态度对吸烟行为的影响。这对未来的研究具有启示意义，即在考察友谊网络对吸烟行为的影响时，应考虑态度因素。本研究的主要局限性在于样本有限，这使得很难将结果推广到一般人群。
