Adolescents with Few Friend Alternatives are Particularly Susceptible to Influence from Friends.

Friend influence in adolescence is well-documented, but the characteristics that contribute to individual differences in susceptibility to influence are not well understood. The present study tests the novel hypothesis that within a friend dyad, having fewer friends than one's partner (i.e., relative lack of alternatives) increases susceptibility to influence as it reduces dissimilarity and thereby promotes compatibility. Drawn from diverse California (USA) public middle schools, participants were 678 adolescents (58% girls) in reciprocated friendships that were stable from the fall to the spring of sixth grade (M = 11.53 years old). Longitudinal Actor-Partner Interdependence Models assessed peer influence, operationalized as individual change in the direction of increased friend similarity. Consistent with the hypothesis, partners with fewer friends were influenced by partners with relatively more friends in self-reported social anxiety and somatic complaints, as well as teacher-reported academic engagement and prosocial behavior. Academic engagement was the only domain wherein partners with more friends were also influenced by partners with relatively fewer friends. For those with few friends, conformity (i.e., becoming more similar to a partner) can be an important strategy to promote compatibility for strengthening existing friendships.

Type and Breadth of High School Extracurricular Activity Involvement and Postsecondary Psychosocial Well-Being among Diverse Youth.

Many youth experience declines in psychosocial well-being during the transition from high school to postsecondary. Hypothesizing that extracurricular activity involvement in high school functions as a resource factor, the current study examines type and breadth as predictors of psychosocial well-being one year postsecondary. The sample (N = 4070) consisted of students from diverse ethnic-racial and socio-economic status backgrounds (30% Latinx; 60% had a parent without a college degree; 47% cisgender female). Eleventh grade involvement in sports was linked with lower loneliness, social anxiety, and depressive symptoms, and higher self-worth, whereas special interest clubs were associated with lower social anxiety and depressive symptoms. Examining breadth, one or two activities were linked with optimal psychosocial well-being. The results suggest that sports and special interest clubs, and up to two activity domains, are associated with optimal psychosocial well-being, providing recommendations for extracurricular programming and youth involvement.

The academic benefits of maintaining friendships across the transition to high school.

Extending past research on the social and academic disruption associated with the transition from middle to high school, this study examined the role of friendship stability. Specifically, the goal was to investigate how friendships maintained from middle school and perceived (academic and emotional) support from friends at ninth grade contributed to school-related affect (e.g., school belonging, academic identification, burnout) at 10th grade. Relying on a sample of 3410 ethnically diverse ninth grade students, multilevel structural equation modeling (MSEM) was conducted on 17,255 friendships. Friendships maintained from middle to high school (versus newly formed) provided greater academic support, and students with a greater number of stable friends reported higher levels of both academic and emotional support from friends. Tests of multiple mediation revealed that friendship maintenance across the high school transition was related with more positive school affect at 10th grade, in part due to higher levels of perceived academic support from friends (e.g., homework help, course-taking advice), but not emotional support. The findings underscore the academic value of maintaining social ties across the high school transition.

Young Adult Adaptability to the Social Challenges of the COVID-19 Pandemic: The Protective Role of Friendships.

The continuing COVID-19 pandemic enables assessment of the adaptability of young adults to non-normative stressors threatening their social-emotional wellbeing. Focusing specifically on a developmentally critical social challenge of restricted in-person contact, the goal of the current study was to examine the role of friendships in alleviating social-emotional problems. Data were collected via online surveys from an ethnically diverse sample (n = 1557) of 20 to 24-year-olds (62% cisgender female, 31% male, 7% gender diverse or gender questioning) in spring of 2021. Longitudinal data from an earlier time point involving an age-normative social challenge (transition out of high school) were used as a comparison. The comparisons between the transition from high school and the pandemic showed that whereas social anxiety and depressive symptoms increased, loneliness decreased. Participants also reported having slightly more friends and rated the overall quality of their friendships as somewhat higher. Regression analyses revealed that a greater number of friends over time and greater satisfaction with friend electronic communication during the pandemic were most robustly related to lower social and generalized anxiety as well as depressive symptoms, over and above earlier social-emotional wellbeing and a number of relevant correlates. Loneliness was protected by higher quality of friendships, greater contact with friends, as well as more frequent and satisfying electronic communication with friends. The results suggest that although young adults are facing emotional challenges during the continued pandemic, they are also able to adapt by keeping in touch with friends to decrease subjective sense of isolation. The findings have novel intervention implications to reduce loneliness.

Developmental changes in the frequency and functions of school-related communication with friends and family across high school: Effects on college enrollment.

As postsecondary education is an increasingly important developmental milestone for adolescents, it is critical to identify supports that help prepare youth for college. Building on evidence highlighting the role of parental input and guidance, the current study investigates how within-person changes in adolescent school-related communication (i.e., frequency of talking about school and educational planning) with friends and family across high school contribute to college preparedness and subsequent enrollment. Capitalizing on a diverse adolescent sample (N = 4,495), longitudinal analyses across high school showed that school-related communication with friends increased, but remained relatively stable with family, from Grades 9-12 (approximately ages 15-18 years). Parallel process latent growth curve modeling demonstrated that steeper increases in school-related communication with friends independently predicted college enrollment, consistently across racial/ethnic and parental education groups. Moreover, within-person changes in friend and family school-related communication across high school interacted in a compensatory fashion to predict grade point average and perceived college readiness at 12th grade. At a time of growing need for independence from parents, the findings highlight the positive developmental function of friends in helping adolescents reach a critical educational milestone.

Navigating the Healthy Context Paradox: Identifying Classroom Characteristics that Improve the Psychological Adjustment of Bullying Victims.

The healthy context paradox-an unexpected pattern in which victims' psychological adjustment worsens as the overall level of victimization in a classroom or school declines-implies that reducing the frequency of bullying or victimization incidents does not do enough to help victims of bullying. In light of this finding, it is imperative to identify protective factors that alleviate victimization-related distress in the peer ecology. The current study examines classroom-level peer victimization and peer-defending behaviors as moderators of the association between individual-level victimization and psychological adjustment. These classroom-level moderators were tested with a sample of 1373 adolescents (40% girls, Mage: 14 years) from 54 classrooms in South Korean middle schools. Consistent with past findings documenting the healthy context paradox, the results of multilevel modeling indicated that victimized youth experienced a lower level of depressive symptoms in classrooms where victimization was more common. Most importantly, bullied students reported fewer depressive symptoms, on average, in classrooms with relatively high levels of bully-oriented (i.e., confronting the bully), rather than victim-oriented (i.e., comforting the victim), defending behavior. These findings provide a more nuanced understanding of the role of peers' defending behaviors toward bullied adolescents and have significant implications for anti-bullying interventions.

Gender Discrimination, Perceived School Unfairness, Depressive Symptoms, and Sleep Duration Among Middle School Girls.

The current study examines how gender discrimination by adults in school is linked with depressive symptoms and sleep duration over time in middle school. The main goal is to test one psychological mechanism that can account for such associations: perceived school unfairness. Relying on a racially-ethnically diverse sample of girls (N = 2,718, Mage  = 13.01, SDage  = 0.39) from 26 middle schools, multilevel mediation analyses revealed that girls who experienced school-based gender discrimination by an adult in seventh grade reported higher levels of perceived school unfairness in eighth grade. Moreover, perceived unfairness, in turn, was associated with more depressive symptoms and shorter sleep durations by eighth grade. Implications of changes in adolescent girls' sleep and mood related to their experiences of gender discrimination are discussed.

School and Cybervictimization Across High School: Normative Developmental Trajectories and Bidirectional Links with Loneliness.

The current study examines normative developmental trajectories of school and cybervictimization across 3 years of high school and tests whether school and cybervictimization experiences predict increases in loneliness at school or whether loneliness at school increases the risk of victimization. Gender differences are also explored. Data were drawn from a longitudinal sample of 4,339 ethnically diverse U.S. adolescents (Mage  = 15.02) who completed surveys in 9th, 10th, and 11th grades. Whereas school victimization decreased, cybervictimization increased across high school. School-based victimization and loneliness were bidirectionally related across time (controlling for cybervictimization), but cybervictimization and loneliness were not related (controlling for school victimization). The findings provide a nuanced account of the associations between school and cybervictimization with feelings of isolation at school.

Engagement Norms Buffer Academic Risks Associated with Peer Rejection in Middle School.

The current study examined school variations in academic engagement norms and whether such norms affect those most susceptible to peer influence. We presumed that behaviors associated with perceived popularity make norms salient and are most likely to affect socially marginalized (rejected) youth. Focusing on differences across 26 middle schools, the main aim was to test whether academic engagement norms moderate the association between peer rejection and subsequent academic difficulties. The U.S. public school sample included 5,991 youth (52% girls): 32% Latino/a, 20% White, 14% East/Southeast Asian, 12% African American, and 22% from other specific ethnic groups. Multilevel models were used to examine whether engagement norms moderated the association between sixth grade peer rejection and changes in grade point average (GPA) and academic engagement across middle school (i.e., from sixth to eighth grade). Consistent with our contextual moderator hypothesis, the association between peer rejection and academic engagement was attenuated-- and in the case of GPA eliminated-- in schools where higher engagement was a salient norm. The study findings suggest that the behaviors of popular peers affect those on social margins, and that academic difficulties are not inevitable for rejected youth.

Peer rejection as a precursor of romantic dysfunction in adolescence: Can friendships protect?

INTRODUCTION: Using a prospective longitudinal design across six years, the current study investigated whether adolescents' experiences of peer rejection across middle school increased their risk of maladaptive (aggressive and unsupportive) behaviors in high school romantic relationships. Additionally, friendship quality following the transition to high school was examined as a potential protective factor. METHODS: The sample consisted of 1,987 ethnically diverse youth (54% female; Mage = 17.10) who were romantically involved at eleventh grade. Peer rejection (based on peer nominations) was assessed at four time points across three years in middle school. Students reported on their friendship quality in ninth grade and their aggressive (e.g., shouting; hitting) and supportive (e.g., listening; helping) behaviors towards a romantic partner in eleventh grade. RESULTS: Results demonstrated that adolescents who were increasingly rejected by peers during middle school were more likely to behave aggressively towards their romantic partners in high school. Friendship quality at the beginning of high school moderated prospective links from rejection to support, such that escalating middle school peer rejection predicted less supportive romantic behaviors only among youth with low-quality friendships at ninth grade. These patterns were documented over and above the effects of sex, ethnicity, socioeconomic status, and students' aggressive behavior at the beginning of middle school. CONCLUSIONS: Together, the findings suggest that 1) increasing peer rejection during middle school may spiral into later romantic relationship dysfunction and 2) supportive friendships across a critical school transition can interrupt links between peer and romantic problems.

Interminority Friendships and Intergroup Attitudes Across Middle School: Quantity and Stability of Black-Latino Ties.

Cross-ethnic friendships are associated with better intergroup attitudes, especially among youth from societally dominant groups. In spite of the increasing diversity of the United States school-age population, it is not clear whether friendships between ethnic minority youth ("interminority" friendships) similarly predict intergroup attitudes. Moreover, little is known about the underlying mechanisms that can help account for such friendship effects. To address these gaps, the current study examines the number and the stability (a potential mechanism) of unique cross-ethnic friendships as predictors of intergroup attitudes in a sample of 2580 Black and Latino youth (52% female, 73% Latino) attending 26 ethnically diverse California public middle schools. Youth nominated their close friends across the three years of middle school. Multilevel analyses revealed that the presence of at least one stable Black-Latino friendship positively predicted attitudes, over and above the number of such friendships. These findings indicate that lasting friendships between youth of different ethnic backgrounds may be particularly potent in shaping adolescents' attitudes, as opposed to several, transient relationships. Implications for facilitating stable friendships between youth of different racial/ethnic backgrounds are discussed, including suggestions for future research on interminority friendships.

Cross-class friendship and academic achievement in middle school.

Academic achievement disparities based on parental education are robust during the middle school years. The current study examined whether cross-class friendship (i.e., reciprocal relationships between peers with different levels of parental education) decrease class-based achievement differences during a developmental phase when friends are particularly important. Relying on a sample of 4,288 sixth grade students (M = 12.03 years) from 26 ethnically diverse middle schools, multilevel analyses were conducted predicting seventh-grade grade point average, standardized achievement test scores, and teacher-rated academic engagement. The associations between parental education and academic achievement were reduced when students had at least 1 cross-class friendship at sixth grade. The findings are discussed in terms of how socioeconomic diversity of school-based friendships can level the academic playing field. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Body weight and academic achievement: The role of weight diversity in urban middle schools.

The current study was designed to examine one possible weight stigma-reduction mechanism: school-level weight diversity. It was hypothesized that greater weight diversity among same-sex peers at school would attenuate the negative association between weight and academic achievement. Across 26 urban public middle schools, 5,991 sixth-grade students (52% girls) were included: 12% African American/Black, 14% East/Southeast Asian, 30% Latino, 21% White, and 23% from other specific ethnic groups. Weight diversity was estimated as the likelihood that two randomly selected students would be from different weight categories, using Simpson's index. Standardized achievement test scores and grade point average (GPA) were used to assess academic achievement. Consistent with our contextual moderator hypothesis, high levels of weight diversity at school served a protective function. The negative association between body mass index (BMI) and achievement test scores, as well as GPA (girls only) was nonsignificant at schools with high levels of weight diversity. The study results offer a potential explanation for inconsistent findings regarding body weight and achievement, and a novel methodological approach to capture weight diversity in ways that provide new insights for school-based interventions.

Quality and Stability of Cross-Ethnic Friendships: Effects of Classroom Diversity and Out-of-School Contact.

Cross-ethnic friendships are linked to a range of positive outcomes in adolescence, but have been shown to be lower quality and less stable than same-ethnic friendships. The current study examined how classroom diversity and out-of-school contact contribute to these relational differences between cross-and same-ethnic friendships. Multilevel analyses were conducted on a sample of 9,171 classroom-based friends nested within 4,333 ethnically diverse sixth grade students (54% female; 32% Latino, 20% White, 14% East/Southeast Asian, 12% African American, 14% Multiethnic, 8% Other ethnic). Consistent with the hypotheses, lower ethnic diversity in classes shared by friends and lack of home contact (as opposed to electronic) contributed to relational differences between cross- and same-ethnic friendships. The findings suggest that while diverse classrooms enable youth to bond across ethnic groups, connecting outside of school is critical for the relational quality and longevity of cross-ethnic friendships.

Dynamic Changes in Peer Victimization and Adjustment Across Middle School: Does Friends' Victimization Alleviate Distress?

Although some adolescents are chronically bullied throughout middle school, others may only experience peer victimization temporarily. This study examined the effects of time-invariant (average level) and time-varying (year-to-year) victimization experiences across middle school on adolescents' depressive symptoms, somatic complaints, and self-blame. A key question was whether friends' victimization buffered students from their victimization-related distress. The diverse sample (n = 5,991) was surveyed four times between sixth and eighth grade (Mage at sixth grade = 11.54 years). Three-level multilevel models revealed both time-invariant and time-varying effects of victimization on adjustment, but these maladaptive associations were attenuated when adolescents' friends experienced more victimization across middle school. The results suggest that even temporarily victimized youth may have unmet mental health needs, and sharing social plight with friends can protect victims.

The Effects of Middle School Weight Climate on Youth With Higher Body Weight.

This study examines whether social-emotional difficulties associated with higher body weight vary across schools as a function of the school's weight climate. Weight climate, characterized by weight-policing, was assessed indirectly by examining how strongly self-reported weight predicts victim reputation within 26 ethnically diverse middle schools. Social-emotional indicators included self-reported loneliness, school belonging, and self-esteem. In schools with stronger weight-policing at seventh grade, loneliness was intensified by eighth grade among both girls (n = 2,101) and boys (n = 1,985) with higher weight. Similar effects were found for low self-esteem among girls. Additionally, boys-regardless of their weight-reported lower sense of belonging in schools with stronger weight-policing. The study offers a new method to estimate school weight climate, and the findings provide insights for interventions.

Losing and gaining friends: Does friendship instability compromise academic functioning in middle school?

Extending past research on the academic benefits of having close friends in early adolescence, the study examines how instability of friendships (i.e., losses and gains of friends) is related to academic engagement and performance in middle school. The sample was drawn from a longitudinal study of ethnically diverse youth across 26 middle schools (N = 5991). The results demonstrated that over two thirds of friends were either lost or gained during the first year in middle school. When controlling for friendship network size, both friendship losses and gains were concurrently associated with lower academic engagement and performance at spring of sixth grade. Moreover, higher overall instability during the first year in middle school was related to lower academic engagement in seventh grade, which in turn, predicted lower grade point average (GPA) by the end of middle school. The findings suggest that friendship instability captures a disruptive social process that can compromise academic functioning in middle school.

Friendless Adolescents: Do Perceptions of Social Threat Account for Their Internalizing Difficulties and Continued Friendlessness?

Adolescents who lack friends at school are at risk of internalizing difficulties. This study examined a social-cognitive mechanism underlying friendlessness and internalizing difficulties (i.e., depressive symptoms, social anxiety, low self-esteem). We tested whether perceived social threat (i.e., peer victimization, sense of unsafety, and peer misconduct) mediates the association between friendlessness and increased internalizing difficulties across middle school. Latent variable structural equation modeling was used to test the model among an ethnically diverse sample of 5,991 (52% female) adolescents. The results demonstrate that friendless sixth-grade students perceived their school environment as more threatening by seventh grade, which in turn, increased internalizing difficulties from sixth to eighth grade. Perceptions of threat also predicted friendlessness at the end of middle school.
