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.

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.

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.

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.

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.

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.

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.

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.

When and How Do Students Benefit From Ethnic Diversity in Middle School?

The effects of school-based ethnic diversity on student well-being and race-related views were examined during the first year in middle school. To capture the dynamic nature of ethnic exposure, diversity was assessed both at the school-level (n = 26) and based on academic course enrollments of African American, Asian, Latino, and White students (n = 4,302; M = 11.33 years). Across all four pan-ethnic groups, school-level ethnic diversity was associated with lower sense of vulnerability (i.e., feeling safer, less victimized, and less lonely) as well as perceptions of teachers' fair and equal treatment of ethnic groups and lower out-group distance. Underscoring the role of individual experiences, exposure to diversity in academic classes moderated the association between school-level diversity and the two aforementioned race-related views.

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.

Friends in Activities, School-related Affect, and Academic Outcomes in Diverse Middle Schools.

Participating in school-based activities is linked to positive academic engagement and achievement, but less is known about how peer relationships within activities affect these outcomes. The current study examined friends in extracurricular activities as a predictor of academic outcomes in multiethnic middle schools in California. Specifically, the mediating role of school belonging, and interactions by ethnicity and type of activity, were examined in a sample including African American or Black, East or Southeast Asian, White, and Latino youth in extracurricular activities (N = 2268; Mage = 13.36 in eighth grade; 54% female). The results of multilevel mediational models suggested that school belonging mediated the link between friends in activities and academic outcomes, and these findings replicated across groups based on ethnicity and the type of activity in which one was involved in general. These results are discussed in terms of how activities can be structured to promote positive peer relations in ways that are linked with academic engagement and achievement.

Gender Norm Salience Across Middle Schools: Contextual Variations in Associations Between Gender Typicality and Socioemotional Distress.

Youth who feel they do not fit with gender norms frequently experience peer victimization and socioemotional distress. To gauge differences between schools, the current study examined the longitudinal effects of school-level gender norm salience-a within-school association between gender typicality and peer victimization-on socioemotional distress across 26 ethnically diverse middle schools (n boys = 2607; n girls = 2805). Boys (but not girls) reporting lower gender typicality experienced more loneliness and social anxiety in schools with more salient gender norms, even when accounting for both individual and school level victimization. Greater gender norm salience also predicted increased depressed mood among boys regardless of gender typicality. These findings suggest particular sensitivity among boys to environments in which low gender typicality is sanctioned.

Emotional Implications of Weight Stigma Across Middle School: The Role of Weight-Based Peer Discrimination.

This study considered the emotional consequences of weight stigmatization in early adolescence by examining the effects of weight-based peer discrimination across middle school. Sampled across 26 urban middle schools, 5,128 youth (52% girls) with complete body mass index data at sixth or 7th grade were included: 30% Latino, 21% White, 14% East/Southeast Asian, 14% Multiethnic, 12% African American/Black, and 9% from other specific ethnic groups. About one third of the sample reported at least one weight-discrimination incident at 7th grade. Controlling for sixth-grade adjustment, perceptions of weight-based peer discrimination at 7th grade were stronger predictors of body dissatisfaction, social anxiety, and loneliness (and somatic symptoms for girls but not boys) at 8th-grade than 7th-grade body mass index. Moreover, heavier body stature during the 1st year in middle school was associated with increased body dissatisfaction by the end of middle school in part due to weight-related disrespectful, exclusionary, and demeaning treatment by peers. Weight-based peer discrimination helps us understand one of the stigmatizing mechanisms underlying the relation between heavy body stature and the progression of emotional problems in early adolescence.

Extracurricular Activities in Multiethnic Middle Schools: Ideal Context for Positive Intergroup Attitudes?

This study examined processes by which extracurricular participation is linked with positive ethnic intergroup attitudes in multiethnic middle schools in California. Specifically, the mediating roles of activity-related cross-ethnic friendships and social identities including alliances with multiple groups were examined in a sample including African American or Black, East or South-East Asian, White, and Latino youth (N = 1,446; Mage  = 11.60 in sixth grade). Results of multilevel modeling suggested that in addition to activity-related cross-ethnic friendships, complex social identities mediated the association between availability of cross-ethnic peers in activities and ethnic intergroup attitudes. Results are discussed in terms of how activities can be structured to promote cross-ethnic relationships and complex social identities, as well as positive ethnic intergroup attitudes.

Do I fit in? Psychosocial ramifications of low gender typicality in early adolescence.

The current longitudinal study was designed to examine one of the possible underlying mechanisms that can help account for why low gender typicality (i.e., not feeling like a typical boy or girl) is related to subsequent psychosocial adjustment problems: peer victimization. Relying on a large (N = 5,991, 52% female), ethnically diverse U.S. sample, the results suggested that peer victimization at 7th grade partially accounts for associations between 7th grade gender typicality and 8th grade social anxiety, somatic complaints, and externalizing behavior, when controlling for earlier (e.g., 6th grade) levels of adjustment. Associations were similar across ethnic groups. Peer victimization mediated associations for boys and girls across all outcomes; however, girls showed stronger associations with somatic complaints and boys showed stronger associations with externalizing behavior. These results suggest that attempts to improve adjustment for youth feeling low gender typicality should focus in part on reducing peer victimization.

Identification with Multiple Groups in Multiethnic Middle Schools: What Predicts Social Ingroup Overlap?

Self-definition becomes a central task during early adolescence, as youth identify with multiple social groups. Focusing on ethnic identification and identification with other salient social ingroups (e.g., those based on extracurricular activities), we examined predictors of perceived ingroup membership overlap among ethnically diverse adolescents (n = 1264; M age = 12.51; 53 % female). Social ingroup overlap remained relatively stable, but decreased, across the seventh to eighth grade. The number of cross-ethnic classmates in seventh grade predicted lower overlap in the eighth grade, and cross-ethnic friendships by eighth grade mediated this association. Findings underscore the opportunities provided by multiethnic middle schools for youth to connect and befriend one another across ethnic lines, as well as to foster divergent social identities that are associated with positive intergroup attitudes.

Depressive symptoms, friend distress, and self-blame: Risk factors for adolescent peer victimization.

Past research indicates that depressed adolescents experience increased risk for peer victimization. Less is known about the conditions under which depressive symptoms predict social vulnerability and the mechanism underlying such links. The current study considers a) characterological self-blaming attributions as a social cognitive mechanism accounting for links between depressive symptoms and victimization across the first two years of middle school and b) the potential moderating role of friends' level of depressive symptoms. Relying on an ethnically diverse sample of 5,374 adolescents, multilevel moderated mediation analyses indicated that maladaptive attributions accounted for links between 6th grade depressive symptoms and increases in 7th grade victimization. Moreover, this mediational pathway was strongest for students whose friends also experienced heightened depressive symptoms at the beginning of middle school. These results highlight the roles of both intra- and inter-personal risk factors in predicting social cognitive biases and future victimization risk during the middle school years.
