Socio-cognitive correlates of primary school children's deceptive behavior toward peers in competitive settings

Competing for limited resources with peers is common among children from an early age, illustrating their propensity to use deceptive strategies to win. We focused on how primary school-age (6-8 years old) children's strategic deception toward peers is associated with their socio-cognitive development (theory of mind and executive functions). In a novel computerized competitive hide-and-seek game, we manipulated the peer opponents' familiarity (familiar vs. unfamiliar) and actions (following vs. not following children's indications), as well as the stimuli likability (liked vs. disliked cards). Our findings demonstrated that children deceived the familiar opponent less than the unfamiliar one, indicating their determination to preserve positive peer interactions. We showed that theory of mind and executive functions significantly predicted children's willingness to deceive. Notably, second-order false belief understanding and visuospatial working memory positively predicted children's use of truths to deceive, whereas inhibitory control and cognitive flexibility efficacy scores were negatively related to their deceptive performance when using the same strategy. Implications for children's competitive behavior toward peers involving lie-telling are discussed.

Neural processing of observed performance-based errors and rewards in the context of friends and unfamiliar peers across adolescence

Adolescence is characterized by changes in performance monitoring, whereby action outcomes are monitored to subsequently adapt behavior and optimize performance. Observation of performance-based outcomes (i.e., errors and rewards) received by others forms the basis of observational learning. Adolescence is also a period of increasing importance of peers, especially friends, and observing peers forms a crucial aspect of learning in the social context of the classroom. However, to our knowledge, no developmental fMRI studies have examined the neural mechanisms underlying observed performance monitoring of errors and rewards in the context of peers. The current fMRI study investigated the neural correlates of observing performance-based errors and rewards of peers in adolescents aged 9-16 years (N = 80). In the scanner, participants observed either their best friend or an unfamiliar peer play a shooting game resulting in performance-dependent rewards (based on hits) or losses (based on misses, i. e, errors), where outcomes affected both the player and the observing participant. Findings showed higher activation in the bilateral striatum and bilateral anterior insula when adolescents observed peers (i.e., best friend and unfamiliar peer) receive performance-based rewards compared to losses. This might reflect the heightened salience of observed reward processing in the peer context in adolescence. Our results further revealed lower activation in the left temporoparietal junction (TPJ) while adolescents observed the performance-based outcomes (rewards and losses) for their best friend than for an unfamiliar peer. Considering that observation of others' performance-based errors and rewards forms the basis of observational learning, this study provides a crucial first step in understanding and potentially improving adolescent observational learning in the peer context.

Social relationship provisions and loneliness in school: Child- and classroom-level effects

Building on social needs theory (Weiss, 1974), this study introduces the construct of classroom provision richness and examines the association between the exchange of social provisions among children in classrooms and children's feelings of loneliness in school. We examined the receipt of provisions from reciprocally nominated friends versus unilateral (one-sided) and non-friend classmates and examined associations between social provisions and loneliness at the child and classroom levels. Participants were 998 third- through fifth-grade children (468 girls, 530 boys; 88.5% White) in 38 classrooms who indicated which classmates they played with, helped, validated, and provided opportunities for self-disclosure. In addition to the social provisions nomination measure, children responded to (a) a measure of loneliness that avoided content overlapping with social provisions, (b) a rating-scale sociometric measure of peer acceptance, and (c) a measure that asked them to indicate which classmates engaged in prosocial, aggressive, or withdrawn-type behaviors. Multilevel analyses indicated that social provisions received from reciprocal friends and from unilateral-received friends were associated with children's feelings of loneliness in school. Furthermore, a measure of the provision richness of classrooms moderated the association between child-level provisions received and feelings of loneliness, such that children who received fewer provisions were less lonely in classrooms that were more provision-rich. Classroom provision richness was also associated with the general level of prosocial behavior and peer acceptance in the classroom. Together, findings suggest that efforts to foster the exchange of social provisions in classrooms could reduce loneliness and facilitate a more caring classroom environment.

Emotion Regulation in the Classroom: A Network Approach to Model Relations among Emotion Regulation Difficulties, Engagement to Learn, and Relationships with Peers and Teachers

Emotion regulation is theorized to shape students' engagement in learning activities, but the specific pathways via which this occurs remain unclear. This study examined how emotion regulation mechanisms are related to behavioral and emotional engagement as well as relations with peers and teachers. The sample included 136 secondary school students (59,7% girls; M_age = 14.93, SD_age = 1.02, range: 13-18 years). Psychometric network models revealed that difficulties in emotional awareness, emotional clarity, and access to emotion regulation strategies were differentially related to behavioral and emotional engagement, establishing an indirect link with teacher and/or peer relations. Nonacceptance of emotional responses, emotional awareness, and impulse control difficulties were uniquely related to teacher and/or peer relations, establishing an indirect link with student engagement. Causal discovery analysis suggested that student emotional engagement is an empirically-plausible direct cause of increased access to emotion regulation strategies. These findings uncover potential pathways through which emotion regulation hampers or facilitates learning at school, providing information useful for the design of school curricula and teacher training programs.

Friendship quality in adolescence: the role of social media features, online social support and e-motions

The last decade has seen a growing interest in understanding what role social media play in adolescent experiences, including friendship relationships. However, little is known about the associations of specific characteristics of social media and individual factors with friendship quality. This study was designed in line with the tenets of the so-called Transformation Framework (Nesi et al., 2018) with the aim of testing whether and how social media features, online social support, and online expressions of emotions play a role in adolescents' friendship quality. Participants were 744 Italian adolescents (64.5% females) with an average age of 15.9 years (SD = 1.31). First, a path analysis was conducted to test the hypothesized model on the whole sample of adolescents. Finally, two multi-group analyses (MGA) were conducted to analyze differences across gender groups (female vs. male) and group of social media users (problematic vs. non-problematic). Path analysis yielded a complex pattern of associations, in which different perceived social media features were significantly associated with different dimensions of friendship quality, both directly and indirectly via perceived online social support and the tendency to express e-motions on social media. Moreover, MGAs confirmed significant differences among both genders and social media users. The findings provide support for the importance of considering social media as a social context with its own characteristics for the study of adolescents' peer experiences, by taking into consideration that the hypothesized role of social media in supporting friendship relations during adolescence may depend on individual factors.

Peer Victimization, Internalizing Problems, and the Buffering Role of Friendship Quality: Disaggregating Between- and Within-Person Associations

Although many studies have shown an association between peer victimization and internalizing problems, which may be buffered by friendship quality, it is unclear whether these associations apply to within-person processes as well. This would mean that at times when adolescents experience more victimization than they usually do, they also experience more internalizing problems. The current study disaggregated between- and within-person variation to examine the association between peer victimization and symptoms of depression and anxiety, and the protective effect of friend support and conflict. Participants were 497 Dutch adolescents (56% boys) with a mean age of 13.03 (SD_age = 0.45, ranging from 11.68 to 15.56 at Wave 1). They participated in a 6-wave questionnaire study, with each wave taking place approximately one year after the previous. The results showed that peer victimization was associated with depressive symptoms and anxiety across adolescence, both between and within persons. Friend support buffered this association at the between-person level, but not the within-person level. This study highlights the impact of peer victimization and suggests that friend support may partly protect adolescents from the effects of peer victimization.

Adolescent Digital Stress: Frequencies, Correlates, and Longitudinal Association With Depressive Symptoms

PURPOSE

Adolescents are among the most frequent users of social media and are highly attuned to social feedback. However, digital stress, or subjective distress related to social media demands, expectations, and others' approval and judgment, is understudied in adolescents.

METHODS

We conducted a preliminary investigation of self-reported digital stress and its hypothesized correlates (social media, peer status, and mental health variables) among 680 students (M_age = 14.27, SD = .62; 49.2% female).

RESULTS

Nearly half of participants reported experiencing digital stress at least "sometimes," regardless of race or ethnicity; sex differences were small. Digital stress was associated with greater social media use and importance, peer importance, popularity, and all mental health variables. Digital stress was also associated longitudinally with increases in depressive symptoms.

CONCLUSIONS

These preliminary findings suggest the importance of further investigation of digital stress and its effects on adolescent health.

Depressive Symptoms Prospectively Predict Peer Victimization: A Longitudinal Study Among Adolescent Females

Research has consistently demonstrated a relationship between peer victimization, a major issue in early adolescence, and depression. However, longitudinal studies examining the relationship between peer victimization and depressive symptoms have yielded mixed results. Thus, the current study examined how specific aspects of peer victimization and subtypes of depressive symptoms are related over a two-year period. Adolescent females (N = 265) completed a questionnaire battery at baseline and two-year follow-up. Results indicated that baseline depressive symptoms prospectively predict peer overt victimization, relational victimization, and decreased prosocial behaviors at follow-up; baseline peer victimization did not predict depressive symptoms at follow-up. Further, results demonstrate the differential predictive value of specific depressive symptoms for overt vs. relational aggression and decreased prosocial behavior. Taken together, this study provides insight into the impact of depressive symptoms on peer victimization and the importance of addressing peer relations in the context of treatment for adolescent depression.

Parenting, Peers and Psychosocial Adjustment: Are the Same-or Different-Children Affected by Each?

The prospective research presented herein extends work on parent and peer effects on adolescent psychosocial adjustment by looking beyond average effects. Instead, it considers variation in susceptibility to each source of influence in order to assess the extent to which those individuals most and least susceptible to parent effects are similarly-or differentially-susceptible to peer effects. Data from the NICHD Study of Early Child Care and Youth Development (n = 1364, 48.3% female, age range: 10-15 yrs., race/ethnicity: 80.4% white, 12.9% black and 6.7% other) was analyzed to assess the degree to which each child was susceptible to parent and peer effects. Toward this end, an influence statistic, DFBETAS, was used. A significant and moderate positive association between the two susceptibility effects indicated that children most or least susceptible to the effects of quality of parenting proved to be similarly affected by their peers, although this was not the case for a substantial minority of youth. The fact that at least some children vary dramatically in the effects to which they are most susceptible is discussed with respect to potential targets of intervention, namely, parents or peers.

Linking post-stressor interpersonal processes in adolescent girls' close friendships with acute HPA stress responses

INTRODUCTION

For adolescent girls, close friendships may facilitate stress management and mitigate risk for internalizing psychopathology. However, little is known about how friendship processes may buffer (or potentially exacerbate) acute psychobiological responses to interpersonal stressors in ways that affect risk.

METHODS

In a sample of 220 girls (ages 12-17 years) with a history of internalizing symptoms, this study investigated friendship dynamics following the Trier Social Stress Test (TSST) to evaluate associations between post-stressor friendship behaviors (expressions of vulnerability by the stressed teen; support offered by their close friend) and hypothalamic-pituitary-adrenal (HPA) axis stress responses.

RESULTS

Multilevel regression modeling revealed that girls who displayed more pronounced cortisol reactivity expressed greater vulnerability to, and received greater support from, their close friend. Expressed vulnerability was associated with more efficient cortisol recovery. Close friend support was not significantly associated with cortisol recovery, nor did it influence the connection between expressed vulnerability and cortisol recovery.

CONCLUSIONS

Findings suggest that HPA reactivity may prompt expressions of vulnerability to girls' close friends, and in this context, promote more efficient HPA recovery. Findings highlight the role friendship dynamics may play in HPA-related risk for internalizing symptoms and point to expressed vulnerability in adolescent girls' close friendships as a potential consideration for interpersonally-centered therapeutic approaches.

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.

Friendship is more than strategic reciprocity: Preschoolers' selective sharing with friends cannot be reduced to strategic concerns

The current study investigated whether children share especially much with their friends when sharing can be reciprocated (strategic sharing) or whether friendship and strategic reciprocity are independent factors in predicting children's sharing. If the former is the case, children should prefer their friend relatively more in a situation where the friend can reciprocate than in a situation without the possibility for reciprocity. In two experiments, 3- and 5-year-old participants (N = 270) could distribute stickers between themselves and three recipients: a friend, a child who would join the kindergarten group the next day, and a stranger. Half of the children were led to believe that their generosity could be reciprocated, and the other half were not. In Experiment 1, this was implemented by anonymous and nonanonymous sharing. In Experiment 2, the possibility of reciprocity or lack thereof was explicitly mentioned. The results show that participants across both age groups shared more resources with their friend than with less familiar recipients. Potential reciprocity affected 5-year-olds' sharing but not 3-year-olds' sharing-but only if reciprocity was explicitly mentioned (Experiment 2). Importantly, the preference for the friend was independent of the possibility to be reciprocated for all children. The current study shows that friendship and strategic reciprocity are relevant but probably largely independent factors for children's sharing. That is, the preference to share with friends cannot be reduced to strategic considerations.

The Relationship Between Dating Status and Academic and Social Functioning in Middle Adolescence

Dating relationships are normative in middle adolescence, but the academic and social implications of different types of dating involvement remains unclear. To address this gap, this longitudinal study evaluates the association between dating status (i.e., never date, rarely date, casually date, steady relationship) and academic and social functioning in a sample of adolescents. Across two school years, 455 adolescents (53.8% female; 56.5% Asian American, 43.5% Latinx; T1 M_age = 15.04 years) reported on their dating status and peers provided nominations of popularity and aggression. Grades and standardized test scores were obtained from school records. For Asian American youth, abstaining from dating was negatively associated with subsequent popularity. Casual dating and being in a steady relationship were associated with relational and overt peer aggression over time. Gender moderated this association, such that boys in steady relationships, and girls in casual relationships were more relationally aggressive one year later. Implications are discussed in terms of problem behavior theory and adolescent intersexual competition.

"Who will share with me?": Preschoolers rely on their friends more than on their nonfriends to share with them

During the preschool years, children start to share selectively with close affiliates such as friends. However, it is unclear whether preschool children also selectively rely on their own friends more than on their nonfriends to share with them. Moreover, the developmental course of this relationship-dependent reliance is unknown. In the current study, therefore, we investigated to what extent preschoolers rely on their friends and nonfriends to share with them. To this end, we analyzed the choices of 82 3- to 5-year old children by means of a metacognitive opt-out paradigm. Children were led to believe that a friend and a disliked peer have had the opportunity-but have not been obligated-to share a highly valued resource with them by putting it in a box. Children could then choose between the above-mentioned box by their peer and an opt-out box that contained a slightly less attractive but certain item. Thus, children were expected to choose the peer's box only if they thought that their peer had shared with them. Otherwise, they should choose the opt-out option to maximize their outcome. Our results reveal developmental changes with older but not younger preschool children relying on their friends to share with them and relying more on their friends than on their nonfriends. This highlights the developmental changes in selective reliance over the preschool years and gives further insight into how young children learn to navigate the social world.

Multiple Trajectories in Anxious Solitary Youths: the Middle School Transition as a Turning Point in Development

This study aimed to identify divergent patterns of individual continuity and change in anxious solitude (AS) in the last half of elementary school (3rd - 5th grade) and the first two years of middle school (6th - 7th grade), and test predictors and outcomes of these pathways. Participants were 688 youths (girls n = 354, 51.5%; M age at outset = 8.66 years, SD = 0.50). Latent class growth analyses identified two AS trajectory classes in elementary school (moderate-decreasing, high-increasing) and three in middle school (low-stable, low-increasing, high-decreasing). The elementary school moderate-decreasing class was two-and-a-half times more likely than others to end in the middle school low-stable class. In contrast, the elementary school high-increasing class was twice as likely as others to end in the middle school low-increasing class, and four times as likely to end in the middle school high-decreasing class. Peer exclusion predicted membership in increasing AS trajectory classes in both elementary and middle school, whereas the middle school high-decreasing AS trajectory class demonstrated decreasing peer exclusion during middle school. Likewise, inability to defend oneself predicted membership in increasing AS trajectory classes in both elementary and middle school, whereas membership in the middle school high-decreasing AS trajectory class was predicted by inability to defend oneself in elementary but not middle school. High-decreasing AS youths' improved ability to defend themselves in middle school appeared to be related to a cascade of improvements in related domains. In contrast, membership in increasing AS classes in elementary and middle school predicted symptoms of social anxiety and depression.

Preference and popularity as distinct forms of status: A meta-analytic review of 20 years of research

INTRODUCTION

A systematic meta-analysis was conducted of the association between preference and popularity across childhood and adolescence. The role of development, sex, and region of the world were examined.

METHOD

The analysis was conducted on 135 samples including 136,014 participants. The samples were divided by age (upper grades primary school, k = 41; lower grades secondary school, k = 72; upper grades secondary school, k = 22) and region (North America, k = 54; Europe, k = 66; China, k = 10).

RESULTS

Across all samples, a moderate positive association between preference and popularity was found (r = 0.45). The association was significantly weaker in the upper grades of secondary school (r = 0.37) than in the lower grades of secondary school (r = 0.47) or the upper grades of primary school (r = 0.47). The association was weaker for girls (r = 0.26) than for boys (r = 0.38) in the upper grades of secondary school. The association was weaker in European samples (r = 0.41) than in those from North America (r = 0.50) and China (r = 0.57).

CONCLUSIONS

The results confirmed that preference and popularity are related but distinct dimensions of adolescent peer status. The association differed significantly by age, sex, and region of the world. Further research should examine additional factors that explain the variability in the association between preference and popularity.

Emotion Identification in Preschool and Early Adolescent Body Mass Index: Exploring the Roles of Depressive Symptoms and Peer Relations

The ability to identify and label emotions may represent an early-life risk factor that relates to excess weight gain during childhood. The current study investigates the relationships between preschool emotion identification and early adolescent body mass index (BMI), as well as the mediating role of two variables: depressive symptoms and peer relations. In a longitudinal study, preschoolers completed an emotion identification task, and parents completed psychiatric assessments and a peer-relations questionnaire about their child. BMI percentile was measured at later time points in early adolescence. Poor emotion identification during preschool predicted increases in BMI percentile over time, with greater deficits in emotion identification ability relating to steeper increases in BMI percentile across early adolescence. Peer relations in preschool partially mediated the relationship between preschool emotion identification ability and adolescent BMI. This study provides novel information about potential targets for early interventions in the service of obesity prevention.

Effects of a seating chart intervention for target and nontarget students

Teachers' efforts to manage classroom social dynamics can have positive effects on students' social relationships. One way in which teachers may seek to manage these relationships is through seating arrangements. In a randomized control trial, van den Berg, Segers, and Cillessen (2012) found that closer proximity in the classroom can reduce disliking between two students who dislike each other (target students). However, the effect of this intervention on the larger class is unknown. The current study implemented a short version of this seating chart intervention, investigated effects on both target and nontarget students, and explored whether teachers' efficacy to manage social dynamics moderated the effects of the intervention. Data came from 1573 students in 59 Grade 5 classrooms in the Netherlands. Results indicated that students in intervention classes exhibited more overt aggression and perceived less cooperation among classmates than students in the control condition. These effects were consistent across target and nontarget students and were not moderated by teachers' efficacy for managing social dynamics. It may be that the intervention initially causes tension between target students that is resolved first at the dyad level and is only later noticed by other classmates. Whether these initial negative effects for target and nontarget students become positive after a longer period of adjustment and reorganization of relationships is to be determined in further research.

Popular peer norms and adolescent sexting behavior

INTRODUCTION

Adolescents misperceive and are heavily influenced by the behavior of their popular peers, yet research has not yet investigated this phenomenon for a relatively new and potentially risky behavior: adolescent sexting. The present study investigates rates of sexting among popular and non-popular adolescents and the association between adolescents' perceptions of popular peers' sexting behavior and their own sexting behavior.

METHODS

A school-based sample of 626 adolescents from a rural high school in the Southeastern U.S. (M_age = 17.4, 53.5% female) completed surveys indicating whether they had sent a sext in the past year. Participants also reported on perceptions of popular peers' sexting behavior and completed sociometric nominations of peer status.

RESULTS

While 87.4% of adolescents believed the typical popular boy or girl in their class had sent a sext in the past year, only 62.5% of popular adolescents had actually sent a sext. There was no significant difference between rates of sexting among popular and non-popular (54.8%) adolescents. After adjusting for gender and sexual activity status, adolescents who believed that the typical popular peer sent a sext were over ten times more likely to have also sexted in the past year. Among adolescents who believed their popular peers had not sexted, girls were more likely than boys to have sexted themselves; however, this gender difference disappeared among adolescents who believed their popular peers had sexted.

CONCLUSIONS

These results underscore the importance of peer status and perceptions of peer norms in adolescents' sexting.

Risk factors for psychological functioning in German adolescents with gender dysphoria: poor peer relations and general family functioning

Adolescents with gender dysphoria (GD) often face various associated social, emotional, and behavioral difficulties. In such a marginalized group, it is crucial to identify factors that may impact psychological functioning to better accommodate their needs. Therefore, the present study investigated the impact of two specific risk factors, poor peer relations and general family functioning, on the development of psychological problems in adolescents with GD, and their possible interaction effect. The Youth Self-Report, a Peer Relations Scale, and a General Family Functioning scale were assessed in a sample of n = 180 clinically referred adolescents (mean age 15.5; 146 transgender boys with a female birth-assigned sex, and 34 transgender girls with a male birth-assigned sex) with a complete GD diagnosis (fulfillment of the DSM 5 criteria A and B) at their initial admission to the Hamburg Gender Identity Service. Multiple linear regression analysis was conducted to examine the relationship between peer relations, family functioning, and psychological functioning outcomes. Adolescents with GD presented significantly higher Internalizing and Total Problem scores compared to the German reference norm. Externalizing problems were above the norm for transgender boys, but within the normal range for transgender girls. Multiple regression analysis revealed that, overall, adolescents with an advanced age, a female birth-assigned sex, poorer peer relations, and poorer family functioning showed more behavioral and emotional problems. Consequently, incorporating both the family and social environment in transgender care is of high importance to adequately tend to the needs of adolescents with GD.

Investigation of peer relations of preschool refugee and non-refugee children

The purpose of this study is to compare the peer relations of refugee and non-refugee children in preschool period. The study has a causal-comparative design. The study sample included a total of 40 children, of whom 20 were refugee children and 20 were non-refugee children. In the study in which the random sampling and purposeful sampling method were used, the data were collected by using "General Information Form", "Ladd-Profilet Child Behavior Scale" and "Peer Victimization Scale". FINDINGS: It was found as a result of the study that even though there was no significant difference in terms of the items of "aggressive with peers", "fearful-anxious towards peers", "prosocial behaviors with peers", "excluded by peers", the hyperactivity and peer victimization in refugee and non-refugee children, a significant difference was found between the asocial behaviors of refugee and non-refugee children. According to their mean ranks, it was observed that the refugee children who showed less aggression with peers and prosocial behaviors towards their peers were more anxious/fearful and displayed asocial behaviors, were excluded more by their peers, were less hyperactive and were exposed to more peer violence. According to these results, it can be recommended to develop social skill programs for refugee and non-refugee children and determine the current situation by spreading the sample to larger groups.

School adjustment of first-grade primary school students: Effects of family involvement, externalizing behavior, teacher and peer relations

Adjusting to school contributes to the healthy introduction of all educational activities. For this reason, it is important to determine all facilitating and debilitating factors to the school adjustment process and to develop preventive studies for overcoming school adjustment. The purpose of this study is to determine the factors affecting the school adjustment of first-grade primary school students based on an ecological approach. The study group consisted of 81 teachers and 517 parents. The data were gathered for 517 children aged between 64 months and 98 months from public schools located in the central districts of Ankara in the 2015-2016 academic year. Structural equation modeling was used in the present study. Thus, according to the School Adjustment Model, externalizing behaviors, teacher-student relationship, and peer relations have a significant direct impact on first-grade students' school adjustment, whereas family involvement has no statistically significant direct influence on first-grade students' school adjustment. In addition, externalizing behaviors affect school adjustment through the mediating role of teacher-student relationship and peer relations. Also, the total effect of the externalizing behavior variable on school adjustment is -0.55. The student-teacher relationship (B = 0.53) and peer relationship (B = 0.48) variables have also had an effect on school adjustment.

Parent Support of Preschool Peer Relationships in Younger Siblings of Children with Autism Spectrum Disorder

Preschool-aged siblings of children with ASD are at high-risk (HR) for ASD and related challenges, but little is known about their emerging peer competence and friendships. Parents are the main providers of peer-relationship opportunities during preschool. Understanding parental challenges supporting early peer relationships is needed for optimal peer competence and friendships in children with ASD. We describe differences in peer relationships among three groups of preschool-aged children (15 HR-ASD, 53 HR-NonASD, 40 low-risk, LR), and examine parent support activities at home and arranging community-based peer activities. Children with ASD demonstrated precursors to poor peer competence and friendship outcomes. Parents in the HR group showed resilience in many areas, but providing peer opportunities for preschool-age children with ASD demanded significant adaptations.

Transformation of Adolescent Peer Relations in the Social Media Context: Part 1-A Theoretical Framework and Application to Dyadic Peer Relationships

Investigators have long recognized that adolescents' peer experiences provide a crucial context for the acquisition of developmental competencies, as well as potential risks for a range of adjustment difficulties. However, recent years have seen an exponential increase in adolescents' adoption of social media tools, fundamentally reshaping the landscape of adolescent peer interactions. Although research has begun to examine social media use among adolescents, researchers have lacked a unifying framework for understanding the impact of social media on adolescents' peer experiences. This paper represents Part 1 of a two-part theoretical review, in which we offer a transformation framework to integrate interdisciplinary social media scholarship and guide future work on social media use and peer relations from a theory-driven perspective. We draw on prior conceptualizations of social media as a distinct interpersonal context and apply this understanding to adolescents' peer experiences, outlining features of social media with particular relevance to adolescent peer relations. We argue that social media transforms adolescent peer relationships in five key ways: by changing the frequency or immediacy of experiences, amplifying experiences and demands, altering the qualitative nature of interactions, facilitating new opportunities for compensatory behaviors, and creating entirely novel behaviors. We offer an illustration of the transformation framework applied to adolescents' dyadic friendship processes (i.e., experiences typically occurring between two individuals), reviewing existing evidence and offering theoretical implications. Overall, the transformation framework represents a departure from the prevailing approaches of prior peer relations work and a new model for understanding peer relations in the social media context.

"They Think that I Should Defend": Effects of Peer and Teacher Injunctive Norms on Defending Victimized Classmates in Early Adolescents

Norms have been suggested as important characteristics of the social-ecological context for defending victimized peers, but little is known about the contribution of student perceived injunctive norms (regarding the appropriateness of defending) imposed by peers and teachers. To investigate the role of these norms in defending, a sample of 751 early adolescents (51% female; M_age at Time 1:13 years) was assessed at two time points. Defending, as measured by peer- and self-ratings, decreased slightly over a six-month timespan. Three-level models (with time, students, and classrooms as the levels) indicated that both individual- and classroom-level perceived peer injunctive norms (but not teacher injunctive norms) had positive effects on defending over time regardless of the source of the information on defending (peers or self). These findings support programs that encourage defending through peer norms.

Applying Social Cognitive Theory to Explore Relational Aggression across Early Adolescence: A Within- and Between-Person Analysis

In the past two decades, there has been a significant amount of research on children's relational aggression, which has been found to be associated with psychosocial problems. Longitudinal studies have examined changes in relational aggression during early adolescence in relation to individual characteristics; however, most studies compare individual differences between people with regard to rates of relational aggression. A shortcoming to the current literature is the lack of studies that use a multilevel approach to examine individual differences (between-person) as well as the extent to which individuals deviate from their own typical levels (within-person) over time. In this study, within- and between-person psychological and peer-related predictors of rates of relational aggression over time were examined. Participants included 1,655 students in 5th-8th grade (mean age: 13.01) from four public middle schools in the Midwest, which consisted 828 females and 827 males. In terms of race and ethnicity, 819 (49.5%) were African Americans, followed by 571 (34.5%) Whites, and 265 (16%) Others. Longitudinal data were collected over four waves across two years of middle school. The findings indicated that contrary to the hypothesis that relational aggression would increase over time, there was no significant growth across time. Age, gender, and race were not associated with relational aggression over time; however, consistent with the Social Cognitive Theory, changes in within-person impulsivity, anger, and peer delinquency were all positively related to increases in relational aggression. At the between-person level of analysis, depressive symptoms and peer delinquency were related to relational aggression. Findings suggest that school-based programs that address anger management, impulsivity, empathy, and victimization could help prevent relational aggression.

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals' own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.

Investigating the Potential Impact of Social Talk on Prevention Through Social Networks: the Relationships Between Social Talk and Refusal Self-Efficacy and Norms

Interpersonal communication among participants plays an important role in the impact and effectiveness of prevention programs (Southwell & Yzer, Communication Theory 19:1-8, 2009). This study focused on adolescents' informal conversations about a prevention program, referred to as social talk, from a social network perspective. We provide both a conceptualization of social talk in relation to prevention programs and an operationalization of it by examining adolescents' social networks. Participants (N = 185) were eighth-grade students attending a middle school substance-abuse prevention program called keepin' it REAL (kiR). Participants engaged in both positive and negative social talk about kiR. Students with higher friendship indegree centrality were more likely to have greater positive social talk indegree centrality (r = .23 p < .01). These results indicated that youth considered as friends by most of their classmates were also reported as being positive in their comments with respect to kiR. Youth who talked positively about kiR tended to report personal anti-substance injunctive norms (b = 0.71, p < .05). On the other hand, youth who were nominated as negative social talkers by their peers appeared to have less personal anti-substance injunctive norms (b = -0.92, p < .05). Furthermore, youth who were more likely to talk negatively about kiR were less likely to perceive that their best friends (b = -1.66, p < .05) or most youth in their age (b = -1.49, p < .05) disapprove of substance use.

Psychological functioning in adolescents referred to specialist gender identity clinics across Europe: a clinical comparison study between four clinics

Adolescents seeking professional help with their gender identity development often present with psychological difficulties. Existing literature on psychological functioning of gender diverse young people is limited and mostly bound to national chart reviews. This study examined the prevalence of psychological functioning and peer relationship problems in adolescents across four European specialist gender services (The Netherlands, Belgium, the UK, and Switzerland), using the Child Behavioural Checklist (CBCL) and the Youth Self-Report (YSR). Differences in psychological functioning and peer relationships were found in gender diverse adolescents across Europe. Overall, emotional and behavioural problems and peer relationship problems were most prevalent in adolescents from the UK, followed by Switzerland and Belgium. The least behavioural and emotional problems and peer relationship problems were reported by adolescents from The Netherlands. Across the four clinics, a similar pattern of gender differences was found. Birth-assigned girls showed more behavioural problems and externalising problems in the clinical range, as reported by their parents. According to self-report, internalising problems in the clinical range were more prevalent in adolescent birth-assigned boys. More research is needed to gain a better understanding of the difference in clinical presentations in gender diverse adolescents and to investigate what contextual factors that may contribute to this.

Classroom social experiences in early elementary school relate to diurnal cortisol levels

Social stress has been linked to altered hypothalamic-pituitary-adrenocorticol (HPA) axis activation. During elementary school, children can become exposed to negative peer relations, such as poor appraisal among classroom peers, which is considered a social stressor. However, little is known about the association between classroom peer appraisal and the physiological stress system in children. The goal of this study was to examine the association of peer acceptance and peer non-acceptance with diurnal cortisol concentrations in 222 children from 20 mainstream elementary schools (Mage=6.97years, SD=0.99, 55% boys) in the Netherlands. Saliva samples were collected at awakening, 30min post-awakening, at noon and at 8 pm during a weekend day. From these assessments, the Cortisol Awakening Response (CAR), diurnal cortisol concentration (AUC_g) and diurnal cortisol slope were calculated. Peer nominations of peer acceptance (being liked), and peer non-acceptance (being disliked) were collected across a one year interval. Associations were controlled for peer victimization, age, sex and SES and children's levels of emotional problems and behavioural problems. Results showed that low peer acceptance was associated with heightened diurnal cortisol concentration (i.e., heightened AUG_g), lower cortisol reductions across the day (i.e., less decreasing cortisol slope) and heightened cortisol awakening response (i.e., heightened CAR). Peer non-acceptance and the interaction between peer acceptance and peer non-acceptance (known as peer rejection) were not associated with AUCg, cortisol slope or the CAR. The findings emphasize the association between poor appraisal among classroom peers and children's heightened HPA-axis activation. This underscores the importance of the physiological stress system in studying the consequences of negative peer relations in children.

Chronic Childhood Peer Rejection is Associated with Heightened Neural Responses to Social Exclusion During Adolescence

This functional Magnetic Resonance Imaging (fMRI) study examined subjective and neural responses to social exclusion in adolescents (age 12-15) who either had a stable accepted (n = 27; 14 males) or a chronic rejected (n = 19; 12 males) status among peers from age 6 to 12. Both groups of adolescents reported similar increases in distress after being excluded in a virtual ball-tossing game (Cyberball), but adolescents with a history of chronic peer rejection showed higher activity in brain regions previously linked to the detection of, and the distress caused by, social exclusion. Specifically, compared with stably accepted adolescents, chronically rejected adolescents displayed: 1) higher activity in the dorsal anterior cingulate cortex (dACC) during social exclusion and 2) higher activity in the dACC and anterior prefrontal cortex when they were incidentally excluded in a social interaction in which they were overall included. These findings demonstrate that chronic childhood peer rejection is associated with heightened neural responses to social exclusion during adolescence, which has implications for understanding the processes through which peer rejection may lead to adverse effects on mental health over time.

Co-Rumination Exacerbates Stress Generation among Adolescents with Depressive Symptoms

Through stress generation, individuals' own thoughts and behaviors can actually lead to increases in their experience of stress. Unfortunately, stress generation is especially common among individuals who are already suffering from elevated depressive symptoms. However, despite the acknowledgement that some individuals with depressive symptoms generate greater stress than others, few studies have identified specific factors that could exacerbate stress generation among individuals with depressive symptoms. The present study examines co-rumination as a factor that might exacerbate stress generation among adolescents with depressive symptoms using a short-term longitudinal design. Considering these processes among adolescents was critical given that many youth experience increases in depressive symptoms at this developmental stage and that co-rumination also becomes more common at adolescence. Participants were 628 adolescents (326 girls; 302 boys) who reported on their depressive symptoms, experiences of stress, and co-rumination with a best friend. Interpersonal stressors (peer and family stress) and non-interpersonal stressors (school and sports stress) were assessed. Consistent with past research, adolescents with depressive symptoms experienced greater interpersonal and non-interpersonal stress over time. Importantly, co-rumination interacted with both depressive symptoms and gender in predicting increases in peer stress. Depressive symptoms predicted the generation of peer stress only for girls who reported high levels of co-rumination with friends. Implications for protecting youth with depressive symptoms against stress generation are discussed.

Children's Intergroup Relations and Attitudes

The existence of warm, intimate, supportive, and egalitarian relationships between members of differing social outgroups is likely, at the societal level, to facilitate cooperation and cohesion, and at the individual level, to promote positive social, educational, and occupational outcomes. The developmental pathway from intergroup contact to intergroup attitudes as it operates among children is not, however, well understood. In our chapter, we review and integrate selected social and developmental science related to intergroup relations and attitudes with the goal of proposing a conceptual model of the pathway from intergroup contact to positive intergroup attitudes among youth.

Poor peer relations predict parent- and self-reported behavioral and emotional problems of adolescents with gender dysphoria: a cross-national, cross-clinic comparative analysis

This study is the third in a series to examine behavioral and emotional problems in children and adolescents with gender dysphoria in a comparative analysis between two clinics in Toronto, Ontario, Canada and Amsterdam, the Netherlands. In the present study, we report Child Behavior Checklist (CBCL) and Youth Self-Report (YSR) data on adolescents assessed in the Toronto clinic (n = 177) and the Amsterdam clinic (n = 139). On the CBCL and the YSR, we found that the percentage of adolescents with clinical range behavioral and emotional problems was higher when compared to the non-referred standardization samples but similar to the referred adolescents. On both the CBCL and the YSR, the Toronto adolescents had a significantly higher Total Problem score than the Amsterdam adolescents. Like our earlier studies of CBCL data of children and Teacher's Report Form data of children and adolescents, a measure of poor peer relations was the strongest predictor of CBCL and YSR behavioral and emotional problems in gender dysphoric adolescents.

Higher Childhood Peer Reports of Social Preference Mediates the Impact of the Good Behavior Game on Suicide Attempt

The Good Behavior Game (GBG) is a universal classroom-based preventive intervention directed at reducing early aggressive, disruptive behavior and improving children's social adaptation into the classroom. The GBG is one of the few universal preventive interventions delivered in early elementary school that has been shown to reduce the risk for future suicide attempts. This paper addresses one potential mechanism by which the GBG lowers the risk of later suicide attempt. In this study, we tested whether the GBG, by facilitating social adaptation into the classroom early on, including the level of social preference by classmates, thereby lowers future risk of suicide attempts. The measure of social adaptation is based on first and second grade peer reports of social preference ("which children do you like best?"; "which children don't you like?"). As part of the hypothesized meditational model, we examined the longitudinal association between childhood peer social preference and the risk of future suicide attempt, which has not previously been examined. Data were from an epidemiologically based randomized prevention trial, which tested the GBG among two consecutive cohorts of first grade children in 19 public schools and 41 classrooms. Results indicated that peer social preference partially mediated the relationship between the GBG and the associated reduction of risk for later suicide attempts by adulthood, specifically among children characterized by their first grade teacher as highly aggressive, disruptive. These results suggest that positive childhood peer relations may partially explain the GBG-associated reduction of risk for suicide attempts and may be an important and malleable protective factor for future suicide attempt.

Early adolescent substance use in Mexican origin families: Peer selection, peer influence, and parental monitoring

BACKGROUND

Because adolescents vary in their susceptibility to peer influence, the current study addresses potential reciprocal effects between associating with deviant peers and use of alcohol, tobacco and other drugs (ATOD), as well as the potential buffering role of parental monitoring on these reciprocal effects.

METHOD

674 children of Mexican origin reported at fifth and seventh grade (10.4 years old at fifth grade) on the degree to which they associated with deviant peers, intended to use alcohol, tobacco or other drugs (ATOD) in the future, and had used controlled substances during the past year. Trained observers rated parental monitoring from video-recorded family interactions at the first assessment.

RESULTS

Youth who intended to use ATODs during fifth grade experienced a relative increase in number of deviant peers by seventh grade, and youth with more deviant peers in fifth grade were more likely to use ATODs by seventh grade. Parental monitoring buffered (i.e., moderated) the reciprocal association between involvement with deviant peers and both intent to use ATODs and actual use of ATODs.

CONCLUSIONS

Parental monitoring can disrupt the reciprocal associations between deviant peers and ATOD use during the transition from childhood to adolescence.

Sex differences in children's investment in peers

It is hypothesized from within an evolutionary framework that females should be less invested in peer relations than males. Investment was operationalized as enjoyment in Study 1 and as preference for interaction in Study 2. In the first study, four- and six-year-old children's enjoyment of peer interaction was observed in 26 groups of same-sex peers. Girls were rated as enjoying their interactions significantly less than boys. In the second study, six- and nine-year-old children were interviewed about the individuals with whom they spend time in their homes and neighborhoods and about the individuals who participate in their favorite activities. The proportion of individuals named by children who were peers was significantly lower for girls than boys both in children's neighborhoods and in children's favorite activities. Results strongly support the hypothesis that females and males have evolved differential preferences for interaction with peers.

Associations between social isolation, pro-social behaviour and emotional development in preschool aged children: a population based survey of kindergarten staff

Background

The impact of peer relationships has been extensively reported during adolescence, when peer influence is generally considered to be at its greatest. Research on social isolation during childhood has found associations with school achievement, future relationships and adult mental health. Much of the evidence is derived from either parent or child-rated assessment of peer relationships, each of which have their limitations.

Methods

We report findings from Goodman’s Strengths and Difficulties Questionnaire (SDQ), completed by staff in preschool establishments for over 10,000 children in their preschool year (aged 4–5), linked with routine demographic data. Correlations between scores and demographics were explored. Regression models examined the independent relationships between three social isolation variables, taken from the SDQ Peer Relationship Problems, Pro-social Behaviour and Emotional Symptoms subscales, controlling for demographics.

Results

There were substantial overlaps between problem scores. Regression models found all social isolation variables to be significantly correlated with social and emotional functioning. Different types of social isolation appeared to relate to different psychological domains, with unpopularity having a stronger relationship with poor pro-social skills, whereas being solitary was more strongly linked to poorer emotional functioning.

Conclusions

Social isolation does have a significant association with reported child social and emotional difficulties, independent of demographic characteristics. The analysis highlights the complexity of measuring social isolation in young children. Different types of social isolation were found to have relationships with specific areas of social and emotional functioning.

A randomised controlled trial of a computerised intervention for children with social communication difficulties to support peer collaboration

An intervention aiming to support children with social communication difficulties was tested using a randomised controlled design. Children aged 5-6 years old (n=32) were tested and selected for participation on the basis of their scores on the Test of Pragmatic Skills (TPS) and were then randomly assigned to the intervention arm or to the delayed intervention control group. Following previous research which suggested that computer technology may be particularly useful for this group of children, the intervention included a collaborative computer game which the children played with an adult. Subsequently, children's performance as they played the game with a classmate was observed. Micro-analytic observational methods were used to analyse the audio-recorded interaction of the children as they played. Pre- and post-intervention measures comprised the Test of Pragmatic Skills, children's performance on the computer game and verbal communication measures that the children used during the game. This evaluation of the intervention shows promise. At post-test, the children who had received the intervention, by comparison to the control group who had not, showed significant gains in their scores on the Test of Pragmatic Skills (p=.009, effect size r=-.42), a significant improvement in their performance on the computer game (p=.03, r=-.32) and significantly greater use of high-quality questioning during collaboration (p<.001, r=-.60). Furthermore, the children who received the intervention made significantly more positive statements about the game and about their partners (p=.02, r=-.34) suggesting that the intervention increased their confidence and enjoyment.

Peer-related loneliness across early to late adolescence: normative trends, intra-individual trajectories, and links with depressive symptoms

Study aims were to: (a) describe normative levels and person-oriented developmental trends in loneliness across adolescence, and (2) examine the association between loneliness and depressive symptoms during this same epoch. Participants included 478 youth (239 males and females; 80% Caucasian, 16% African American, and 4% other). Measures of loneliness and multiple indicators of depressive symptoms were gathered yearly across grades 6 through 12 (ages 12-18). Findings implied that most adolescents experience loneliness more strongly during early rather than later adolescence, but not all adolescents traverse the same loneliness trajectories. Youth followed one of five distinct trajectories, characterized as: (a) stable non-lonely, (b) stable low lonely, (c) stable high (chronic) lonely, (d) moderate decliners, and (e) steep decliners. Adolescents following stable high and moderate loneliness trajectories displayed the most depressive symptoms and, although informant differences were found, these youth also manifest the largest gains in depressive symptoms over time.
