Substance use and decision‐making in adolescent best friendship dyads: The role of popularity

In adolescent best friendship dyads, we examined: (a) similarity in substance use and decision‐making; (b) associations between participants' decision‐making and their own and best friend's substance use, (c) the influence of relative popularity within the dyad on these associations. Participants (n = 172; 12–18 years) named their best friend, completed popularity ratings, and a substance use questionnaire. Computer tasks were administered to assess risk‐taking and immediate reward preferences. Reciprocated same‐sex best friendship dyads (n = 49) were distinguished on their popularity, and we controlled for age differences between dyads in the analyses. Best friends were similar in substance use and risk‐taking preferences. More popular friends' risk‐taking preferences were positively associated with alcohol use of less popular friends. These findings underscore best friendship similarity in risky behaviors, and the influence of popular friends.     

Links between friends’ behaviors and the emergence of leadership in childhood: A genetically informed study of twins

Using a genetically informed design, this study examined whether children's leadership behavior varied as a function of their reciprocal friends’ behavioral characteristics. Specifically, we tested (a) whether friends’ use of a dual strategy (specifically, indirect aggression with prosocial behavior) was associated with children's leadership behavior and (b) whether, in line with a gene‐environment interaction (GxE), the predictive association between friends’ behaviors and children's leadership behavior varied depending on the child's genetic likelihood for leadership. The sample comprised 239 Monozygotic and same‐sex Dizygotic twin pairs (50% boys) assessed in grade 4 (mean age = 10.4 years, SD = 0.26). Reciprocal friendship and children's and their friends’ prosocial, indirectly aggressive, and physically aggressive behaviors were measured via peer nominations. Children's and friends’ leadership was measured through teacher ratings. Multilevel regression analyses revealed that children's genetic likelihood for leadership was positively associated with their leadership behavior. Moreover, the higher their genetic likelihood for leadership, the more children displayed increased leadership behavior when friends showed a combination of indirect aggression and prosocial behavior (GxE). These results underline the role of friends’ behaviors in explaining children's leadership. Socializing with bistrategic friends seems to foster leadership skills especially in children with a genetic likelihood for leadership.     

Body Image and Body Change Strategies Within Friendship Dyads and Groups: Implications for Adolescent Appearance‐based Rejection Sensitivity

Appearance‐based rejection sensitivity (appearance‐RS) consists of concerns about, and expectations of, rejection because of one's appearance (Park). This study examined dyadic‐ and group‐level friendship characteristics as correlates of early adolescents' appearance‐RS. Using subgroups of an initial sample of 380 participants, appearance‐RS was examined within best friend relationships (N = 132, M_age = 13.84) and friendship groups (N = 186, M_age = 13.83). Overall, best friends were similar in their appearance‐RS, body dissatisfaction, restrictive dieting, appearance‐conditional self‐worth, appearance values, and self‐rated attractiveness. Similarities between individuals and their friendship groups were consistent with the findings for dyads, except for self‐rated attractiveness and dieting. Appearance‐RS was higher in adolescents whose best friends and friendship groups reported greater restrictive dieting and appearance‐conditional self‐worth. In general, associations did not differ for boys and girls, but having a higher proportion of boys in the friendship group was associated with lowered appearance concerns.     

Friends in high places: A dyadic perspective on peer status as predictor of friendship quality and the mediating role of empathy and prosocial behavior

Friendships and peer status play important roles in the social landscape of adolescents and are related to developmental outcomes. Yet, how peer status is related to friendship quality and what role social skills play in this association remains unclear. In this study, we use Actor–Partner Interdependence (Mediation) Modeling (Ledermann, Macho, & Kenny, 2011 ) to investigate how two forms of peer status, preference and popularity, are related to positive and negative friendship quality in mid‐adolescence. Results show that adolescents who are friends with more preferred (i.e., likeable) and popular adolescents report higher friendship quality. These partner effects were partially mediated by adolescents’ own prosocial behavior and their friends’ empathy levels. Higher levels of empathy of one's friend and one's own lesser preference for equity explained why adolescents were more satisfied in a friendship with highly preferred (i.e., likeable) adolescents. Interestingly, empathy was not a mediator for the link between friendship quality and popularity. These findings promote a better understanding of the interplay between different levels of social complexity (i.e., individual, dyadic and peer group level) in adolescence.     

Relating Individual Control, Social Understanding, and Gender to Child–Friend Interaction: A Relationships Perspective

According to a relationships perspective, it is critical to consider how the individual behaviors and characteristics of both partners shape their social interaction. Adopting a relationships approach to the investigation of children's friendships, we examined how preschool children's and their friends’ controlling behaviors, social understanding, and gender were related to their dyadic interaction. Child–friend dyads (n = 49) were videotaped in two laboratory play sessions (free play and sharing task), and child interviews assessed understanding of emotions and false beliefs. Both children's indirect control was associated with coordinated play during the free play session, and both children's direct control was associated with conflict during the sharing task. Moreover, dyadic interaction varied as a function of study children's social understanding, friends’ social understanding, and play session. An interaction between gender composition and play session also emerged for dyadic conflict. Multiple regression analyses suggested that study children's controlling behaviors accounted for associations between dyadic interaction and more ‘distal’ individual factors (i.e., social understanding, gender). The findings underscore the need to examine how both children's individual competencies are related to the quality of their dyadic interaction and illuminate how the associations between individual factors and dyadic interaction are moderated by the interactive context.     

Linkages between parent—child interaction and conversations of friends

In this study we examined how mothers' and fathers' parenting behavior during parent—child interaction related to children's ability to successfully interact with peers. Children's ability to engage in coordinated interaction, and their negativity and positivity towards peers were examined. Observational data were collected on 56 families in both parent—child and peer interaction settings. Results suggested that father's emotional volatility was related to children's tendency to play at a low level of engagement with their best friends (e.g. engage in parallel play or monologue). Both mother's and father's affective communication were related to children's tendency to play at a higher level of engagement, such as through establishing common ground activities, exchanging information, and self-disclosing personal information or feelings. Parental intrusiveness, low engagement and use of derisive humor was also related to children's negativity during peer interaction. Results support the hypothesis that both fathers and mothers provide a context for children's development of the ability to engage in and maintain interpersonal interaction, and mothers' parenting may influence the amount of positive affect children express during dyadic play.     

Exploring dyadic teacher–child interactions,emotional security,and task engagement in preschool children displaying externalizing behaviors

Based on attachment theory, we tested whether the link between dyadic teacher–child interactions and task engagement operates through a child's security with the teacher. In a sample of preschoolers (N = 470) rated by their teachers as exhibiting elevated disruptive behaviors, the quality of dyadic teacher–child interactions and children's security were observed using a standardized task. Children's engagement with tasks was both observed in the preschool classroom and rated by the teacher. Results indicated that the quality of teacher–child dyadic interactions was associated directly with teacher‐reported task engagement, and indirectly associated, through a child's security, with observed task engagement. We discussed the contribution of these findings to our understanding of how the quality of dyadic teacher–child interactions may serve to regulate children's behavior in the classroom for children whose teachers perceive them as displaying early externalizing behaviors.     

The Friendship Features of Preschool Children: Links with Prosocial Behavior and Aggression

This study assessed features of young children's friendships and determined whether the features reported were associated with prosocial and aggressive behavior. Teachers completed the friendship features questionnaires (FFQ) on the mutual friendships in their class identified by the 98 children who were interviewed (M age =3.91 years). Four subscales (support, conflict, exclusivity/intimacy, and asymmetry) were differentiated from the 36‐item questionnaire. Teacher reports of friendship features showed moderate inter‐rater reliability and were associated with teacher reports of aggression and prosocial behavior and peer reports of acceptance and rejection. Friendship support was positively correlated with prosocial behavior, friendship conflict was positively correlated with overt aggression and peer rejection, and friendship exclusivity/intimacy was positively associated with relational aggression and negatively with peer acceptance. Findings are consistent with research on school age children's friendship features and their behavioral correlates.     

Relations between close friendships and adolescent aggression: Structural and behavioral friendship features

Friendships have the potential to perpetuate or mitigate youth's aggressive behavior. We investigated concurrent and longitudinal effects of friendships on aggression by examining both structural (size and interconnectedness of the local friendship network) and behavioral (friends' aggression) friendship features. Participants were 868 sixth to eighth grade middle‐school students (M = 12.10 years; 49.9% girls; 44% Latina/o) who completed questionnaires at two time points. Participants nominated their friends; reciprocal friendship nominations were used to calculate structural friendship group features (size and interconnectedness). Peer nominations were also used to measure youth's and their friends' aggression. Having more reciprocal friends was associated with more aggression concurrently (particularly for youth whose friends were highly aggressive), and having an interconnected friendship group was associated with decreased aggression over time. Given that findings were different for group size and interconnectedness, we discuss the unique importance of each of these structural friendship features. Practical implications regarding the potential to decrease aggressive behavior based on specific friendship features are also discussed.     

Associations between sleep consolidation in infancy and peer relationships in middle childhood

Sleep plays an important role in many aspects of children's development. Research on children's sleep and their peer relationships has begun to emerge in the last years. However, these studies are mostly cross‐sectional. The current study aimed to investigate the associations between infant sleep and peer relationships in middle childhood. The sample comprised 72 children. Sleep was measured at 1 year using a sleep diary completed by mothers. In the second and third grades of elementary school (7 and 8 years of age), mothers and fathers reported on their children's functioning with peers. When they were in third grade, children were interviewed regarding their friendship quality with a best friend. Results revealed negative associations between children's sleep consolidation (i.e., ratio of nighttime sleep) and parent‐reported peer problems, and positive associations between sleep consolidation and perceived friendship quality. These findings suggest that well‐regulated sleep in infancy may help children develop the skills necessary for later appropriate social functioning in peer contexts.     

Maladaptive Peer Relationships and the Development of Relational and Physical Aggression During Middle Childhood

This study examined the unique roles of peer rejection and affiliation with aggressive peers in the development of relational and physical aggression in a sample of 979 2nd through 4th grade children. Information about target children and their best friends’ aggression and peer rejection was gathered via peer‐nominations when the majority of children were in the 3rd grade, and again approximately one year later. Friendships were identified by having target children nominate their three best friends in their classroom. Path analyses conducted with children who had at least one reciprocated friendship revealed that peer rejection and friends’ aggression predicted changes in target children's aggression; however, the patterns of relations varied by gender and form of aggression. Higher initial levels of rejection and friends’ relational aggression predicted increases in relational aggression among girls only, whereas rejection and friends’ physical aggression predicted increases in physical aggression among boys and girls. The significance of these results for the application of peer influence theories to relational aggression, and to females, is discussed.     

Children's Interpretations of Ambiguous Provocation From Their Siblings: Comparisons With Peers and Links to Relationship Quality

This study investigated how six‐ to eight‐year‐old children interpret ambiguous provocation from their siblings. In particular, we examined how children's attributions of their siblings' intent (1) differed from those for their peers, (2) varied as a function of the structural features of the sibling relationship, and (3) were associated with the affective qualities of the sibling relationship. A total of 121 children were presented with ambiguous provocation scenarios in which three groups of agemates were described as the perpetrators of harm (siblings, friends, and disliked peers). Scenarios were designed to assess children's attributions of hostile, instrumental, and accidental intent. Children attributed more hostile intent to disliked peers than to siblings and less hostile intent to friends than to siblings. Accidental and instrumental intent attributions were equally likely for friends and siblings but less common for disliked peers. Children attributed more hostile intent to older siblings, and more instrumental intent to laterborn siblings who were chronologically younger. Children's attributions of siblings' intent were related to both parents' and children's reports of the affective features of siblings' interactions. Results provide new insight into how children's construals of others' actions are grounded in the unique features of their relationships with particular interaction partners.     

Longitudinal dyadic analyses of emotion dysregulation and mother–child relationship quality in Chinese children with teacher‐reported oppositional defiant disorder

This study examined whether and how mothers' and children's perceptions of mother–child relationship quality mediated associations between mothers' and children's initial emotion dysregulation and children's emotion dysregulation and oppositional defiant disorder (ODD) symptoms 2 years later. The participants were 155 Chinese children with teacher‐reported ODD and their mothers derived from a three‐wave (2 years apart) longitudinal study. A multiple‐informant approach and a dyadic analysis approach (i.e., actor–partner interdependent modeling) were used. The results revealed that (a) mothers' and children's emotion dysregulation was significantly related to their own and their partners’ concurrent perceptions of relationship quality; (b) mothers' and children's perceptions of relationship quality from Wave 1 to Wave 2 were stable but were also interdependent, such that one's own perception of relationship quality at Wave 1 related to the partner's perception at Wave 2; and (c) relationship quality at the two waves interdependently mediated the associations between mothers' and children's emotion dysregulation at Wave 1 and children's emotion dysregulation and ODD symptoms at Wave 3. Implications for family intervention programs targeting maternal and child emotion dysregulation and strengthening mother–child relationship quality for children with ODD were discussed.     

A Cross-Cultural Exploration of the Stability of Children's Friendships and the Predictors of their Continuation

The purpose of this study was to explore cultural differences in children's perceptions of friendship quality and in the predictors of the subsequent continuation of their relationships. Participants were third and fourth-grade children in Florence, Italy, and Toronto, Canada. A total of 184 dyads of children who indicated that they were friends near the beginning of the school year completed questionnaires regarding the quality of their relationships. Among the Italian children, especially the girls, a higher proportion of friendships remained intact at the end of the school year than among the Canadians. Positive aspects of relationship quality at the first data collection point were associated with future friendship status, but earlier conflict within the dyad was unrelated to the continuation of friendship. The levels of conflict reported by the children were lower in the Italian sample than in Canada.     

Gender and friendship: relationships within peer groups of young children

We examined the influences of developing gender segregation on children's friendship maintenance in a longitudinal sample of 40 (17 girls) children who began their peer group experiences as infants. Friendships were behaviorally identified and social interaction was observed and rated six times between average age 16.3 months and average age 49.1 months. The proportion of cross-gender friendships increased with age only when children formed friendships outside of the core group of peers with whom they had begun infant care. Girl-girl and cross-gender friendships were more likely to be maintained than boy-boy friendships. Cross-gender friends tended to be similar in gregariousness in both toddler and preschool periods, similar in hostile aggression as toddlers, and similar in withdrawn behavior as preschoolers. Same-gender friends were not similar in social interaction style. Social skill similarity was generally more important as a basis for friendship in the toddler periods than in the preschool periods. However, cross-gender friends tended to be similar in social skills throughout both the toddler and preschool periods.     

Friendship and Delinquency: Selection and Influence Processes in Early Adolescence

Positive association of relevant characteristics is a widespread pattern among adolescent friends. A positive association may be caused by the selection of similar others as friends and by the deselection of dissimilar ones, but also by influence processes where friends adjust their behavior to each other. Social control theory argues that adolescents select each other as friends based on delinquency. Differential association theory, on the other hand, argues that adolescent friends influence each other's delinquency levels. We employ new statistical methods for assessing the empirical evidence for either process while controlling for the other process. These methods are based on ‘actor‐oriented’ stochastic simulation models. We analyze longitudinal data on friendship networks and delinquent behavior collected in four waves of 544 students in 21 first‐grade classrooms of Dutch secondary schools. Results indicate that adolescents select others as friends who have a similar level of delinquency compared with their own level. Estimates of the social influence parameters are not significant. The results are consistent with social control theory but provide no support for differential association theory.     

Interplay between Friends' Aggression and Friendship Quality in the Development of Child Aggression during the Early School Years

The aim of this study was to investigate the unique and combined role of friendship quality and friends' aggression in regard to the persistence of young children's physical aggression from kindergarten to grade 2. The sample included 1555 children (808 girls) assessed annually using teacher ratings. Two theoretical perspectives (i.e., the social learning and the social bonding perspectives) served as frameworks to guide the analyses and interpret the results. In line with the social learning perspective, friends' aggression was related to a significant increase in children's physical aggression. However, in line with the social bonding perspective, good friendship quality played both a compensatory and a protective role, by, respectively, reducing children's initial level of physical aggression and by mitigating, albeit marginally, the associations between friends' and children's physical aggression. These results suggest that fostering a positive relationship between friends in the early school years may decrease physical aggression even if the friends are aggressive.     

Preschoolers' Mind‐related Comments During Collaborative Problem‐solving: Parental Contributions and Developmental Outcomes

Preschool children's mind‐related comments were analyzed during collaborative problem‐solving interactions with mothers and fathers, and in relation to parental mind‐mindedness (MM) and children's concurrent theory of mind (ToM). Seventy‐two parents (36 fathers, 36 mothers) and their four‐year‐olds participated. Parents' comments to encourage independent thinking and children's own mind‐related comments were expected to mediate, in serial, the relationship between parental MM and children's ToM. The proposed model of mediation received empirical confirmation. In addition, mothers and fathers were found to perform similarly on two measures of MM and in their usage of autonomy promoting and control comments. Finally, no differences were found in the frequency of children's mind‐related comments during interactions with fathers and mothers.     

Domestic Violence, Emotional Competence, and Child Adjustment

This article examined emotion competence in children exposed to domestic violence (DV). It also examined the hypothesis that children's emotional competence mediates relations between DV and children's later difficulties with peers and behavioral adjustment. DV was assessed when children were at the age of five, emotional competence was assessed at the age of 9.5, and peer quality and behavioral adjustment were obtained at the age of 11. Children from homes with greater DV were less aware of their own emotions and more emotionally dysregulated at the age of 9.5. Emotional awareness mediated the relationship between DV at the age of five and children's friendship closeness and internalizing problems at the age of 11. Emotion dysregulation mediated the relationship between DV at the age of five and children's negative peer group interactions, social problems, and internalizing and externalizing problems at the age of 11. Results are discussed in terms of the impact of DV on children's emotional development and the role that different aspects of emotional competence play in children's socio‐emotional adjustment.     

Peer and Friend Influences on Children's Eating

Peers and friends are perceived as important role models for the formation of children's attitudes and behaviours. A wealth of research has aimed to establish the contribution of peers and friends to children's developing eating behaviours, and their attitudes towards eating. This review describes and evaluates such research. Experimental research examining peer modelling of food consumption and liking is reviewed, and several individual child factors that are suggested to make children more or less receptive to peer and friend influences are discussed. The influence of children's perceptions of their peers’ and friends’ eating behaviours upon their own eating practices is also explored. The benefits of future longitudinal research to improve understanding of peer and friend influences on children's eating are emphasized.
