The aim of this study is to examine the role of Dutch second grade (age 13–14) high school peer networks in mediating socioeconomic background and school type effects on smoking behavior. This study is based on a longitudinal design with two measurement waves at five different high schools, of the complete networks of second grader friendships, as well as their smoking behavior, school type, and parents’ educational level. The analysis is done by simulation investigation for empirical network analysis (SIENA) modeling that can control for friendship selection on the basis of smoking similarity when assessing friends’ influence on smoking. The findings show that, when controlling for friendship selection, the influence of friends still plays a significant role in adolescent smoking behavior, and suggests that socioeconomic background and school type effects on smoking are mediated by the friendship networks at school.

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.

This article empirically examines the effect of social background, education, and school organization on adolescent tobacco use in the Netherlands. We test theories of norm enforcing and horizon expanding social networks and distinction by examining the relationship between daily smoking behavior and school organization. Using the 2007 Dutch National School Survey on Substance Use, we find that individual student characteristics are more important predictors than school characteristics. Importantly, social background effects are clearly mediated by school tracks, suggesting that tracking helps us to explain social gradients in substance use. However, school context plays almost no role in adolescent smoking behavior. One exception concerns students in the general track, for whom we find that smoking is further reduced when they are placed in the same school organization as students of the vocational track. This is in line with the theory that tracking differences are magnified in a context where interaction between students from different tracks is promoted.
