The Small School Friendship Dynamics of Adolescent Depressive Symptoms

To Make and Keep Friends: The Role of Health Status in Adolescent Network Tie Formation and Persistence

Health status may shape network structure through network dynamics (tie formation and persistence) and direction (sent and received ties), net of typical network processes. We apply Separable Temporal Exponential Random Graph Models (STERGMs) to National Longitudinal Study of Adolescent to Adult Health survey data (n = 1,779) to differentiate how health status shapes network sent and received tie formation and persistence. Results indicate that networks are shaped by withdrawal of adolescents experiencing poor health, highlighting the importance of separating distinct and directed processes of friendship formation and persistence when considering how health relates to adolescent social life.

Developmental pathways of depressive symptoms via parenting, self-evaluation and peer relationships in young people from 3 to 17 years old: evidence from ALSPAC

PURPOSE

Self-evaluation and interpersonal factors are theoretically and empirically linked to depression in young people. An improved understanding of the multifactorial developmental pathways that explain how these factors predict depression could inform intervention strategies.

METHODS

Using structural equation modeling, this study explored whether self-evaluation and interpersonal factors were associated with adolescent depressive symptoms in a population-based sample (n = 11,921; Avon Longitudinal Study of Parents and Children, ALSPAC), across four development stages: early and late childhood plus early and middle adolescence from 3 to 17 years old.

RESULTS

Early good parenting practices predicted self-esteem, fewer peer difficulties, good friendships and fewer depressive symptoms in late childhood development outcomes. Higher self-esteem and less negative self-concept mediated the effect of early good parenting practice on reduced depressive symptoms in middle adolescence. The hypothesized erosion pathway from depressive symptoms in late childhood via higher levels of negative self-concept in early adolescence to depressive symptoms in middle adolescence was also confirmed. Additionally, peer difficulties played a mediation role in developing depressive symptoms. Contrary to the hypothesis, poor friendships predicted fewer depressive symptoms. The analysis supported a developmental pathway in which good parenting practices in early childhood led to fewer peer difficulties in late childhood and to less negative self-concept in early adolescence, which in turn predicted fewer depressive symptoms in middle adolescence.

CONCLUSION

The social-developmental origin of youth depressive symptoms was supported via the effect of peer relationships in late childhood on self-evaluation in early adolescence.

Embedded Distress: Social Integration, Gender, and Adolescent Depression

In adolescence, teens manage close friendships while simultaneously evaluating their social position in the larger peer context. Conceptualizing distinct local and global network structures clarifies how social integration relates to mental wellbeing. Examining local cohesion and global embeddedness in the context of key factors related to mental health, such as gender and friends' depression, can further distinguish when the structure and content of social integration relate to higher and lower depressive levels. Analyses using survey data from PROSPER (n = 27,091, grades 9-12) indicate global embeddedness is generally protective, but for girls, greater global embeddedness when friends are more depressive is associated with increased depressive symptoms. For girls, greater local cohesion reduces associations between more depressive friends and increased depressive levels, while for boys, both local cohesion and friends' depression are largely irrelevant. Results indicate the importance of considering both local and global network integration in tandem with gender and friends' depression to understand how social integration relates to mental health.

Who Does Cohesion Benefit? Race, Gender, and Peer Networks Associated with Adolescent Depressive Symptoms

Adolescence is a developmental period when peer network structure is associated with mental health. However, how networks relate to distress for youth at different intersecting racial/ethnic and gender identities is unclear. Using National Longitudinal Study of Adolescent to Adult Health survey data, cross-sectional models examine peer network cohesion predicting adolescent depressive levels for racial/ethnic and gender groups. The analytic sample is N = 13,055, average age 15.3 years, 50.2% female, 68.8 % White, 17.2% Black, 9.7% Hispanic, and 4.2% Asian. The results indicate that average cohesion, depressive levels, and cohesion associated with depressive levels differ by race/ethnicity and gender, with the greatest benefits for White and Black girls. This work clarifies patterns of adolescent networks and mental health by race/ethnicity and gender.

Toward understanding the functions of peer influence: A summary and synthesis of recent empirical research

Compelling evidence demonstrates that peer influence is a pervasive force during adolescence, one that shapes adaptive and maladaptive attitudes and behaviors. This literature review focuses on factors that make adolescence a period of special vulnerability to peer influence. Herein, we advance the Influence-Compatibility Model, which integrates converging views about early adolescence as a period of increased conformity with evidence that peer influence functions to increase affiliate similarity. Together, these developmental forces smooth the establishment of friendships and integration into the peer group, promote interpersonal and intragroup compatibility, and eliminate differences that might result in social exclusion.

"Adolescents who feel depressed are rejected but do not withdraw: A longitudinal study of ethnically diverse friendship networks in England, Sweden, and Germany"

Adolescents who feel depressed are likely to experience social isolation from friends. Previous studies have put forward at least four hypotheses that can account for the association between felt depression and social isolation. The hypotheses are: (1) adolescents who are rejected tend to feel more depressed, (2) adolescents who feel depressed tend to become rejected, (3) adolescents who withdraw from friends tend to feel more depressed, and (4) adolescents who feel depressed tend to withdraw from friends. The present study aims to test these four hypotheses in ethnically diverse contexts in three countries. Two waves of data from England (n = 515), Sweden (n = 1,228), and Germany (n = 869) were obtained from the Children of Immigrants Longitudinal Survey in Four European Countries (CILS4EU). One separate stochastic actor-oriented model of the longitudinal coevolution of friendship networks and felt depression was estimated for each of the three countries using the statistical package RSiena. The results consistently indicated that, in all three countries, adolescents who felt depressed were rejected by their peers. Also, the results consistently indicated that adolescents who felt depressed sought more friends, and the results therefore refuted the suggestion that adolescents who feel depressed withdraw from their friends. The findings of the study can inform health-promotion interventions that attempt to limit the social isolation of adolescents who feel depressed in ethnically diverse contexts. More specifically, the study suggests that the social isolation of adolescents who feel depressed may be limited through interventions that reduce the rejection that these adolescents experience from their peers.

When Friends Bring You Down: Peer Stress Proliferation and Suicidality

Peers play a significant role in adolescent mental well-being and suicidality. While social integration among peers is often assumed to benefit mental health, a growing literature recognizes that peer relationships can increase suicidality. Conceptualizing friends' disclosure of mental distress as a stressor on teens' own mental health clarifies how distressed peers relate to suicidal ideation given integration in key social contexts, such as school. This study applies the stress process to examine peer depression and self-harm disclosure as stressors predicting teens' suicidal ideation. Using cross-sectional data from an understudied context, youth in Saudi Arabia (n = 545, 50% female, mean age = 16.8), models find friends' disclosure of depression and self-harm are associated with adolescents' higher suicidal ideation net of their own depression. Teens who are more attached to school see higher risk of suicidality from friends' depression, while friends' self-harm predicts higher suicidality overall. Results challenge assumptions of uniformly beneficial social integration by indicating that friends' mental distress, particularly self-harm, can act as a stressor increasing youth suicidality.

What is(n't) a friend? Dimensions of the friendship concept among adolescents

Much research in network analysis of adolescent friendships assumes that friendships represent liking and social interaction, friendships are directed, and friendships are equivalent to one another. This study investigates the meaning of friendship for eight diverse cohorts of sixth graders. Analysis of focus group and survey data suggests that these adolescents construe friendship as a multidimensional role relation composed primarily of relational norms, expectations for mutual behavior. Their friendship definitions may also include mutual liking and interaction, and other structural expectations such as reciprocity, homophily, and transitivity. Lastly, boys and girls weight these dimensions differently in defining friendship.

The Long Shadow of Peers: Adolescent Networks and Young Adult Mental Health

Connections with peers play an important role in adolescent mental health, but their lasting impact is unclear. This study examines whether structural status and support in adolescent networks predict depressive symptoms years later. Using data from the PROSPER Peers study (n = 1017), I find that the persistent effects of networks differ based on the mental health of teens and their friends. Structures of status and support relate to young adult mental health only for individuals who experience depressive symptoms as teens. Among depressive adolescents, popularity predicts lower subsequent depressive symptoms, while high prestige predicts higher depressive symptoms in young adulthood. Embeddedness among depressed friends also predicts higher young adult depressive symptoms. Overall, findings suggest relationships with peers can set the stage for mental health for adolescents who experience depressive symptoms or have depressive friends.

Isolation but Diffusion? A Structural Account of Depression Clustering among Adolescents

Depression can cause people to withdraw from friendships or be avoided by others, protecting others from exposure to that depression. Yet, researchers observe depression contagion, particularly among adolescents. We address this empirical puzzle by examining the role of gender in structuring friendship networks and the implications for isolation and the spreading of depression. Using stochastic actor-based models of friendships among 421 adolescents from mixed-gender, all-girls, and all-boys classrooms in six Taiwanese high schools, we find that networks with only girls are characterized by high reciprocity and low transitivity. This, in turn, facilitates the withdrawal of depressed girls from interactions. In contrast, networks with all boys create more opportunities for depression to spread through interconnected pathways. Our computational experiment further demonstrates that local preferences governing friendship choice influence levels of network connectivity. This, coupled with depression withdrawal and peer influence, shapes depression prevalence at the network level. These findings refine our understanding of the mechanisms through which friendships expose boys and girls unequally to health risks of depression.

International Students’ Cross-Cultural Adjustment: Social Selection or Social Influence?

International education provides students with an opportunity to develop new social networks while they fit in to the new culture. In a three-wave longitudinal study, we investigated how social networks and psychological adjustment coevolve within a group of international students enrolled in a coursework degree at the tertiary level. Using the Stochastic Actor-Oriented Model (SAOM), we identified the occurrences of social selection based on the levels of psychological and sociocultural adjustment. More specifically, students tended to deselect classmates who were dissimilar in their level of psychological adjustment and to befriend those who differed in their levels of sociocultural adjustment. In contrast, little evidence was found to suggest that features of social networks influenced students’ adjustment. Potential applications of this new method to future acculturation research are suggested.

Neither influence nor selection: Examining co-evolution of political orientation and social networks in the NetSense and NetHealth studies

Political orientation is one of the most important and consequential individual attributes studied by social scientists. Yet, we know relatively little about the temporal evolution of political orientation, especially at periods in the life course during which individuals are forming new social relationships and transitioning to new relational contexts. Here we use Stochastic Actor-Oriented models (SAOMs) to examine the co-evolution of political orientation and social networks using two feature-rich, temporal network datasets from samples of students making the transition to college at the University of Notre Dame (i.e. the NetSense and NetHealth studies). Overall, we find a great deal of stability in political orientation, with a slight tendency for the 2011 NetSense study participants to become more conservative during their first four semesters in college, but not the 2015 NetHealth study participants. Partisanship is the best predictor of changes in political orientation, with students who identify or vote as Republicans becoming more conservative over time. Neither network influence nor selection processes seem to be driving observed changes. During this formative period, relatively stable identities such as party affiliation predict changes in political orientation independently of local network dynamics, selection processes, socio-demographic traits, and dispositional factors.

Social network isolation mediates associations between risky symptoms and substance use in the high school transition

The current study examined whether social status and social integration, two related but distinct indicators of an adolescent's standing within a peer network, mediate the association between risky symptoms (depressive symptoms and deviant behavior) and substance use across adolescence. The sample of 6,776 adolescents participated in up to seven waves of data collection spanning 6th to 12th grades. Scores indexing social status and integration were derived from a social network analysis of six schools and subsequent psychometric modeling. Results of latent growth models showed that social integration and status mediated the relation between risky symptoms and substance use and that risky symptoms mediated the relation between social standing and substance use during the high school transition. Before this transition, pathways involving deviant behavior led to high social integration and status and in turn to substance use. After this transition, both deviant behavior and depressive symptoms led to low social integration and status and in turn greater substance use. These findings suggest that the high school transition is a risky time for substance use related to the interplay of increases in depressive symptoms and deviant behavior on the one hand and decreases in social status and integration on the other.

Adolescent Internalizing Symptoms and the "Tightknittedness" of Friendship Groups

Adolescents with depression have lower peer status overall, but tend to befriend each other. We examined the "tightknittedness" of their friendship groups by testing whether adolescent friendship groups' average levels of or variability in internalizing symptoms predict group cohesiveness. We used four waves (9th-12th grades) of survey and social network data on 3,013 friendship groups from the PROmoting School-Community-University Partnerships to Enhance Resilience study. Friendship groups with higher average depressive symptoms were less cohesive; groups with higher average anxiety symptoms had greater reciprocity. Groups with greater variability in depressive symptoms had greater density; variability in anxiety symptoms was not consistently associated with cohesion. The friendship groups of depressed adolescents appear less cohesive than the "typical" adolescent friendship group.

Social Ties Cut Both Ways: Self-Harm and Adolescent Peer Networks

Peers play an important role in adolescence, a time when self-harm arises as a major health risk, but little is known about the social networks of adolescents who cut. Peer network positions can affect mental distress related to cutting or provide direct social motivations for self-harm. This study uses PROSPER survey data from U.S. high school students (n = 11,160, 48% male, grades 11 and 12), finding that social networks predict self-cutting net of demographics and depressive symptoms. In final models, bridging peers predicts higher self-cutting, while claiming more friends predicts lower cutting for boys. The findings suggest that researchers and practitioners should consider peer networks both a beneficial resource and source of risk associated with cutting for teens and recognize the sociostructural contexts of self-harm for adolescents more broadly.

Friend or frenemy? Experiential homophily and educational track attrition among premedical students

Support from experientially similar others-individuals who have been through the same life transition or faced a similar set of stressful circumstances-has been shown to be effective for coping with issues ranging from chronic illness to bereavement. Less research has examined how networks comprised of experientially similar others may shape academic outcomes. Using longitudinal egocentric network data collected from early career premedical students at a large research university (n = 268), results indicate that greater experiential homophily in premeds' networks are associated with a lower likelihood of departing from the premedical career track at the end of the academic year. Interview data (n = 39) highlight three support functions provided by premedical peers that help to explain this relationship: 1) concrete task assistance with assignments and studying, 2) empathic understanding and emotional support, and 3) advice and reassurance from more advanced peers. Results hint at the potential utility of peer support for the retention of students at-risk of straying from the premedical career track, and have implications for other fields of study.

Quantifying the propagation of distress and mental disorders in social networks

Heterogeneity of human beings leads to think and react differently to social phenomena. Awareness and homophily drive people to weigh interactions in social multiplex networks, influencing a potential contagion effect. To quantify the impact of heterogeneity on spreading dynamics, we propose a model of coevolution of social contagion and awareness, through the introduction of statistical estimators, in a weighted multiplex network. Multiplexity of networked individuals may trigger propagation enough to produce effects among vulnerable subjects experiencing distress, mental disorder, which represent some of the strongest predictors of suicidal behaviours. The exposure to suicide is emotionally harmful, since talking about it may give support or inadvertently promote it. To disclose the complex effect of the overlapping awareness on suicidal ideation spreading among disordered people, we also introduce a data-driven approach by integrating different types of data. Our modelling approach unveils the relationship between distress and mental disorders propagation and suicidal ideation spreading, shedding light on the role of awareness in a social network for suicide prevention. The proposed model is able to quantify the impact of overlapping awareness on suicidal ideation spreading and our findings demonstrate that it plays a dual role on contagion, either reinforcing or delaying the contagion outbreak.

Coevolution of adolescent friendship networks and smoking and drinking behaviors with consideration of parental influence

Friendship tie choices in adolescent social networks coevolve simultaneously with youths' cigarette smoking and drinking. We estimate direct and multiplicative relationships between both peer influence and peer selection with salient parental factors affecting both friendship tie choice and the use of these 2 substances. We utilize 1 sample of 12 small schools and a single large school extracted from the National Longitudinal Study of Adolescent to Adult Health. Using a Stochastic Actor-Based modeling approach over 3 waves, we find: (a) a peer selection effect, as adolescents nominated others as friends based on cigarette and alcohol use levels across samples; (b) a peer influence effect, as adolescents adapted their smoking and drinking behaviors to those of their best friends across samples; (c) reciprocal effect between cigarette and alcohol usage in the small school sample; (d) a direct effect of parental support and the home smoking environment on adolescent friendship tie choice in the small school sample; (e) a direct effect of the home smoking environment on smoking across samples; (f) a direct effect of the home drinking environment on alcohol use across samples; and (g) a direct effect of parental monitoring on alcohol use across samples. We observed an interaction between parental support and peer influence in affecting drinking, and an interaction between the home drinking environment and peer influence on drinking, in the small school sample. Our findings suggested the importance of delineating direct and synergistic pathways linking network processes and parental influence as they affect concurrent cigarette and alcohol use.

Teen Alcohol Use and Social Networks: The Contributions of Friend Influence and Friendship Selection

Background

We evaluated the contributions of teen alcohol use to the formation and continuation of new and existing friendships while in turn estimating the influence of friend drinking on individuals’ regular use and heavy drinking.

Method

Longitudinal network analysis was used to assess the mutual influences between teen drinking and social networks among adolescents in two large Add Health schools where full network data was collected three times. Friendship processes were disaggregated into the formation of new friendships and the continuation of existing friendships in a joint model isolating friendship selection and friend influences.

Results

Friends have a modest influence on one another when selection is controlled. Selection is more complicated than prior studies suggest, and is only related to new friendships and not their duration in the largest school. Alcohol use predicts decreasing popularity in some cases, and popularity does not predict alcohol consumption.

Conclusion

Intervention efforts should continue pursuing strategies that mitigate negative peer influences. The development of socializing opportunities that facilitate relationship opportunities to select on healthy behaviors also appears promising. Future work preventing teen substance use should incorporate longitudinal network assessments to determine whether programs promote protective peer relationships in addition to how treatment effects diffuse through social networks.

Perceived discrimination and markers of cardiovascular risk among low-income African American youth

OBJECTIVES

Our study examines the relationship between perceived discrimination and levels of C-reactive protein and blood pressure in low-income youth ages 10-15 years old.

METHODS

Data were collected from 10 to 15 year old focal children and their mothers. Face-to-face interviews were implemented to collect data on stressors including experiences of everyday discrimination from youth. High sensitivity CRP in dried blood spot samples and diastolic and systolic blood pressure were also collected at the time of the interview.

RESULTS

Perceived discrimination among youth was significantly associated with higher levels of CRP, systolic, and diastolic blood pressure. CRP, systolic, and diastolic blood pressure remained significant after controlling for age-adjusted BMI, waist circumference, and other factors.

CONCLUSIONS

Discrimination is a salient risk factor for inflammation and cardiovascular health. Early life course inflammation and cardiovascular reactivity are important candidate pathways through which the repeated exposure to discrimination for minority group members contributes to racial and economic health inequities in adulthood.

Peer influence processes for youth delinquency and depression

This study explores the multiple factors that account for peer influence processes of adolescent delinquency and depression using data from Waves I and II of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Random-effects longitudinal negative binomial models were used to predict depression and delinquency, controlling for social connection variables to account for selection bias. Findings suggest peer depression and delinquency are both predictive of youth delinquency, while peer influences of depression are much more modest. Youth who are more connected to parents and communities and who are more popular within their networks are more susceptible to peer influence, while self-regulating youth are less susceptible. We find support for theories of popularity-socialization as well as weak-ties in explaining social network factors that amplify or constrain peer influence. We argue that practitioners working with youth should consider network-informed interventions to improve program efficacy and avoid iatrogenic effects.

Research Note: The consequences of different methods for handling missing network data in Stochastic Actor Based Models

Although stochastic actor based models (e.g., as implemented in the SIENA software program) are growing in popularity as a technique for estimating longitudinal network data, a relatively understudied issue is the consequence of missing network data for longitudinal analysis. We explore this issue in our research note by utilizing data from four schools in an existing dataset (the AddHealth dataset) over three time points, assessing the substantive consequences of using four different strategies for addressing missing network data. The results indicate that whereas some measures in such models are estimated relatively robustly regardless of the strategy chosen for addressing missing network data, some of the substantive conclusions will differ based on the missing data strategy chosen. These results have important implications for this burgeoning applied research area, implying that researchers should more carefully consider how they address missing data when estimating such models.

Alcohol use among adolescent youth: the role of friendship networks and family factors in multiple school studies

To explore the co-evolution of friendship tie choice and alcohol use behavior among 1,284 adolescents from 12 small schools and 976 adolescents from one big school sampled in the National Longitudinal Study of Adolescent to Adult Health (AddHealth), we apply a Stochastic Actor-Based (SAB) approach implemented in the R-based Simulation Investigation for Empirical Network Analysis (RSiena) package. Our results indicate the salience of both peer selection and peer influence effects for friendship tie choice and adolescent drinking behavior. Concurrently, the main effect models indicate that parental monitoring and the parental home drinking environment affected adolescent alcohol use in the small school sample, and that parental home drinking environment affected adolescent drinking in the large school sample. In the small school sample, we detect an interaction between the parental home drinking environment and choosing friends that drink as they multiplicatively affect friendship tie choice. Our findings suggest that future research should investigate the synergistic effects of both peer and parental influences for adolescent friendship tie choices and drinking behavior. And given the tendency of adolescents to form ties with their friends' friends, and the evidence of local hierarchy in these networks, popular youth who do not drink may be uniquely positioned and uniquely salient as the highest rank of the hierarchy to cause anti-drinking peer influences to diffuse down the social hierarchy to less popular youth. As such, future interventions should harness prosocial peer influences simultaneously with strategies to increase parental support and monitoring among parents to promote affiliation with prosocial peers.

A Dynamic Model of Adolescent Friendship Networks, Parental Influences, and Smoking

Peer and parental influences are critical socializing forces shaping adolescent development, including the co-evolving processes of friendship tie choice and adolescent smoking. This study examines aspects of adolescent friendship networks and dimensions of parental influences shaping friendship tie choice and smoking, including parental support, parental monitoring, and the parental home smoking environment using a Stochastic Actor-Based model. With data from three waves of the National Longitudinal Study of Adolescent Health of youth in grades 7 through 12, including the In-School Survey, the first wave of the In-Home survey occurring 6 months later, and the second wave of the In-Home survey, occurring one year later, this study utilizes two samples based on the social network data collected in the longitudinal saturated sample of sixteen schools. One consists of twelve small schools (n = 1,284, 50.93 % female), and the other of one large school (n = 976, 48.46 % female). The findings indicated that reciprocity, choosing a friend of a friend as a friend, and smoking similarity increased friendship tie choice behavior, as did parental support. Parental monitoring interacted with choosing friends who smoke in affecting friendship tie choice, as at higher levels of parental monitoring, youth chose fewer friends that smoked. A parental home smoking context conducive to smoking decreased the number of friends adolescents chose. Peer influence and a parental home smoking environment conducive to smoking increased smoking, while parental monitoring decreased it in the large school. Overall, peer and parental factors affected the coevolution of friendship tie choice and smoking, directly and multiplicatively.

The differential contributions of teen drinking homophily to new and existing friendships: An empirical assessment of assortative and proximity selection mechanisms

Alcohol use is pervasive in adolescence. Though most research is concerned with how friends influence drinking, alcohol is also important for connecting teens to one another. Prior studies have not distinguished between new friendship creation, and existing friendship durability, however. We argue that accounting for distinctions in creation-durability processes is critical for understanding the selection mechanisms drawing drinkers into homophilous friendships, and the social integration that results. In order to address these issues, we appliedstochastic actor based models of network dynamics to National Longitudinal Study of Adolescent Health data. Adolescents only modestly prefer new friendships with others who drinker similarly, but greatly prefer friends who indirectly connect them to homophilous drinkers. These indirect homophilous drinker relationships are shorter lived, however, and suggest that drinking is a social focus that connects adolescents via proximity, rather than assortativity. These findings suggest that drinking leads to more situational and superficial social integration.

The role of drinking in new and existing friendships across high school settings

We use 9 Add Health high schools with longitudinal network data to assess whether adolescent drinkers choose friends who drink, prefer friends whose friends drink, if selection differs between new and existing friendships, and between schools. Utilizing dynamic social network models that control for friend influences on individual alcohol use, the results show that drinkers do not strongly prefer friends who drink. Instead, they favor close friends whose friends’ drink, suggesting that alcohol matters for selection on the social groups and environments that friends connect each other to. The role of alcohol use differs by whether friendships are new or existing, however, with bridging connections being less stable. Moreover, selection processes, and the implications of alcohol use for friendship, vary in important ways between schools.
