This study investigates the influence of structural transitions to high school on adolescents’ friendship networks and academic grades from 6th through 12th grade, in a direct comparison of students who do and do not transition. We utilize data from 14,462 youth in 51 networks from 26 districts (Promoting School–Community Partnerships to Enhance Resilience). Results underscore the challenging nature of compulsory school changes. Students that structurally transition to high school between eighth and ninth grade, as compared with those who do not, receive fewer friendship nominations following the move and are more likely to become isolates, according to a three-level Poisson model. Students who transition also report significantly lower odds of obtaining high grades after the shift, and these penalties persist throughout high school. Our findings highlight the social and academic difficulties associated with this particular normative adolescent life transition and point to a disruption in social network ties as part of the problem.
We examine gender differences in the extent to which the social network processes of peer influence and friend selection explain why adolescents tend to exhibit similar risky behaviors as their friends for three problem behaviors (smoking, drinking, and delinquency). Using dynamic Stochastic Actor-Oriented Models (SAOMs), we analyze five waves of data on a large sample of 13,214 adolescents from 51 friendship networks. While both processes explain patterns of risky activities for girls and boys, the delinquent behavior of girls is more susceptible to influence and girls are especially likely to select friends who have similar smoking behaviors to their own.
The current study seeks to further our understanding of the social integration of adolescent immigrants by directly analyzing the composition of their friendship networks. Using statistical network analysis, I first consider whether adolescents are more likely to befriend peers who share their immigrant generation status in a large, diverse sample of seventh through twelfth graders from the National Longitudinal Study of Adolescent and Adult Health (n = 67,586). Next, I test whether having a higher proportion of same-generation friends can protect immigrant youth from experiencing negative health outcomes and adopting risky behaviors. Results indicate that adolescents are more likely to form friendships with peers who share their immigrant generation status, and that this tendency is particularly strong for first-generation respondents. Furthermore, immigrant youth with greater proportions of same-generation friends are less likely to report several negative health behaviors and outcomes. My findings suggest that same-generation friendships can serve as a protective mechanism for immigrant youth, which may help explain the existence of an immigrant health paradox.
