We used stochastic actor-based models to test whether the developmental dynamics of friendships and antipathies in preschool peer groups (followed throughout three school years) were co-dependent. We combined choices from three sociometric tasks of 142 children to identify friendship and antipathy ties and used SIENA to model network dynamics. Our results show that different social processes dr...

Using multi-informant data drawn from a prospective study involving 184 youth, mother perpetrated and father perpetrated partner aggression during early adolescence (age 13) was examined as a predictor of five types of disengagement coping strategies in emerging adulthood (age 21): behavioral disengagement, mental disengagement, denial, substance use, and restraint. The ability to develop close...

We conducted a propagation analysis on an open social network, i.e., YouTube, by crawling one of its friendship networks and one of its subscribers (followers) networks. Our study is unique because it investigates the two main types of connections (i.e., friends and followers) within the same environment and interaction features. We observed that the effect on propagation of people who are not ...

Using the National Longitudinal Study of Adolescent Health (Add Health), we utilize the concepts of homophily, blending, and amalgamation to describe the possible friendship patterns of multiracials. Homophily occurs when multiracials are most likely to choose other multiracials as friends. Blending occurs when friendship patterns of multiracials are somewhere in-between those of their monoraci...

This article explores how friendship network characteristics influence subjective well-being (SWB). Using data from the 2003 General Social Survey of Canada, three components of the friendship network are differentiated: number of friends, frequency of contact, and heterogeneity of friends. We argue that these characteristics shape SWB through the benefits they bring. Benefits considered are mo...

I postulate that social norms and individuals’ behaviors are shaped by a common process capable of generating a multitude of outcomes. In games of friendship links and behaviors, I propose k-player Nash stability—a family of equilibria, indexed by a measure of robustness given by the number of permitted link changes, which is (ordinally and cardinally) ranked in a probabilistic sense. Applicati...

This study examined whether self-esteem mediated the association between peer relationships and internalizing problems (i.e., depression and social anxiety). A total of 7290 (3756 girls) adolescents (ages 13–18 years) completed self-report measures of peer relationships, including direct and indirect victimization, social isolation, friendship attachment (alienation and trust) and friendship qu...

The present study merges the fields of attachment and friendships and compares these in online and offline environments. Although currently we know a great deal about the importance of friendships and attachments for healthy development, there is no research to guide our understanding of how attachment style and friendship characteristics are evidenced in online contexts. Participants completed...
