We examined the influence of romantic relationships on the formation and dissolution of adolescent friendships with a longitudinal network sample (N = 133) from age 14 to 15. Using a dynamic, network statistical model (i.e., STERGM), we found that engagement in a romantic relationship shaped friendship homophily over time, with daters becoming friends with other daters, and singles forming friendships with other singles. Partnered adolescents were not more likely than those who were unattached to dissolve their friendships; however, they were significantly less prone to form new friendships over time. Results broaden our understanding of the role of romantic relationships in youth friendships by showing that romantic involvement deters friendship initiation, but when friendships do form, they tend to be among those who are similarly dating. Our study highlights the significance of adopting a dynamic, social network perspective to examine both the formation and breakup of friendship transitions during this pivotal stage of life.
