Racial Discrimination Experiences and Friendship Network Dynamics Among Black and Latinx Youth.

Despite a robust volume of evidence documenting adverse effects of racial discrimination experiences on adolescent adjustment outcomes, relatively little is known about the relational consequences of racial discrimination experiences for adolescent friendship networks. To address this gap, this study examines how racial discrimination experiences shape and are shaped by friendship network dynamics in early and middle adolescence. The current study's goals were to explicate whether relational consequences of racial discrimination experiences for friendship network selection differed between interracial and intraracial friendships among Black and Latinx youth, and how these adolescents were influenced by their friends' racial discrimination experiences. Longitudinal social network analysis was used among a sample of predominantly Latinx and Black middle school students from the southwestern U.S. (n = 1034; 50.1% boys, Mage = 12.1, 13.8% White, 18.6% Black, 53.1% Latinx, 14.4% Other race and multiracial). The results showed that Black and Latinx youth preferred intraracial friends. Above and beyond that, Black youth were more likely to have intraracial friendships when the focal individual reported lower levels of general racial discrimination experiences and higher levels of adult-perpetrated racial discrimination experiences. Black and Latinx adolescents reported increases in general racial discrimination experiences over time, as a function of their friends reporting higher levels of racial discrimination (e.g., peer influence). These findings advance developmental research by showing that racial discrimination experiences are consequential for friendship network dynamics by increasing the likelihood of intraracial friend selection among Black youth and through peer influence processes.

Dynamic Interdependence of Advice Seeking, Loaning, and Recovery Characteristics in Recovery Homes.

Recovery homes in the US provide stable housing for over 200,000 individuals with past histories of homelessness, psychiatric co-morbidity and criminal justice involvement. We need to know more about how these settings help those remain in recovery. Our study measured advice seeking and willingness-to-loan relationships and operationalized them as a dynamic multiplex social network-multiple, simultaneous interdependent relationships--that exist within 42 Oxford House recovery homes over time. By pooling relationship dynamics across recovery houses, a Stochastic Actor-Oriented Modeling (SAOM) framework (Snijders et al., 2010) was used to estimate a set of parameters governing the evolution of the network and the recovery attributes of the nodes simultaneously. Findings indicated that advice and loan relationships and recovery-related attitudes were endogenously interdependent, and these results were affected exogenously by gender, ethnicity, and reason for leaving the recovery houses. Prior findings had indicated that higher advice seeking in recovery houses was related to higher levels of stress with more negative outcomes. However, the current study found that recovery is enhanced over time if advice was sought from residents with higher recovery scores. Our study shows that social embedding, i.e. one's position in relationship networks, affects recovery prospects. More specifically, the formation of ties with relatively more recovered residents as an important predictor of better outcomes.

Friendship Network Dynamics of Aggressive and Rule-Breaking Antisocial Behaviors in Adolescence.

Growing evidence reveals heterogeneity in antisocial behavior and urges the need to distinguish between aggressive and nonaggressive rule-breaking behaviors. This study characterized how aggression and rule-breaking behaviors shaped peer selection and influence. Using a longitudinal social network modeling approach, these questions were addressed in a sample of 1034 ethno-racially diverse early adolescents (49.52% females, Mage = 12.1), who were assessed in fall and spring of the same year. The results showed no evidence of peer selection on aggressive and rule-breaking behaviors, and significant peer influence on aggressive behavior only. Rule-breaking also forecasted a decreased susceptibility to peer influence on aggressive behavior. The findings expanded our knowledge about complex pathways through which heterogeneity in antisocial behavior is reciprocally related to friendship networks.

Preliminary insights into associations between C-reactive protein and social network dynamics.

Recent social psychoneuroimmunology models suggest bidirectional associations between social experiences and the immune system. This work posits that social relationships and networks may influence the functioning of the immune system, but we know little about the role that the immune system plays in how social networks are created and maintained. We examine how salivary C-reactive protein (CRP), as an inflammatory protein, is associated with making new and keeping existing friendship and conflicted relationships among young adult members of a social group. Participants (n = 37; 67.6% female; M age = 18.18 years, 56.81% white/non-Hispanic) provided nominations of friends and individuals with whom they have conflict at wave 1 and two months later at wave 2. At wave 1, in a group setting, participants donated saliva, later assayed for CRP. Stochastic actor-based models revealed that CRP levels were negatively associated with keeping existing friends and positively associated with developing new friendships. We also found that CRP levels were negatively associated with creating new conflicted relationships and predicted an increased likelihood that group members continue conflicted relationships with the focal individual. These preliminary results support the premises of recent social psychoneuroimmunology models by suggesting that inflammation can also serve as a signal to seek new supportive relationships such as friendships and avoid creating new relationships characterized by threat and/or conflict. Findings provide new insights into the theorized function of the immune system for social approach and withdrawal patterns through which our social connections are constructed.

Loneliness and cortisol are associated with social network regulation.

This study examines how loneliness and the body's stress response system interact to regulate social connections. We suggest that the drive to reconnect signaled by loneliness can be accompanied physiologically by the production of cortisol, which can offer supportive coping resources. Thus, we investigated how loneliness, cortisol levels, and their interaction predicted changes in network connections in a social organization. Participants (n = 193; 53% female) provided friendship network data at two times. At time 1, participants reported on loneliness and donated saliva (later assayed for cortisol). Results revealed that concurrently, lonely individuals reported fewer friendships, whereas over time, they named more friends. These results support the hypothesis that loneliness is a signal to develop connections. We also explored whom lonely individuals befriended over time. Results showed that cortisol significantly moderated the preference for friends with a similar level of loneliness. Specifically, lonely individuals with higher cortisol befriended those who were less lonely over those who were lonelier. Thus, cortisol levels may serve an adaptive function in mobilizing resources to develop connections that fulfill social belongingness needs. Results supported the theorized signaling function of loneliness and revealed that loneliness and the stress response system interact to shape social connections.

Targets' Social Relationships as Antecedents and Consequences of Workplace Bullying: A Social Network Perspective.

Research on workplace bullying has largely focused on individual and organizational factors that place individuals in a vulnerable position. Although theorists have highlighted social aspects of workplace bullying and its antecedents, the role of individuals' social relations with other members of their organization has rarely been examined empirically. Drawing on insights from social network research and research on social rejection, the purpose of this study was to examine the relationship between exposure to bullying and employees' informal social relationships (here: friendships; negative relationships) with other members of their organization. Data from two waves of surveys among 249 employees in eight organizations in Finland were analyzed using stochastic actor-oriented modeling. We found that employees' centrality (i.e., the number of their relationships) had no effect on exposure to bullying. However, exposure to bullying affected targets' perceptions of their relationships with colleagues: employees who had experienced bullying subsequently reported significantly more friendship relationships, but not significantly more negative relationships, suggesting that aggressive or antisocial responses may be more muted in field settings than in experimental settings. Our study contributes to research on workplace bullying by providing a more detailed understanding of the relationship between workplace bullying and employees' social relations, and by offering insights about the consequences of workplace bullying for targets' social relations.
