Predicting changes in classroom aggression status norms: The role of teachers’ normative beliefs and students’ perceived support

This study examined variations in the development of classroom aggression popularity norms, as well as the role of homeroom teachers’ aggression beliefs and students’ perceptions of teachers’ support as predictors of such variations. To achieve this goal, a sample of 63 classrooms were assessed at four time points during a school year, in nine Colombian schools. Results indicated that, overall, classroom aggression popularity norms have a nonlinear trajectory with an increase that peaks at the end of the school year. Also, we found that teachers’ aggression beliefs were concurrently associated with aggression popularity norms across time, and that teachers’ support prevented the increase in these norms. These findings are discussed considering their practical implications for preventing aggression in the school context.

Change over time in interactions between unfamiliar toddlers

The frequency and length of games, conflicts, and contingency sequences that took place between toddlers as they got to know one another were studied using archival data. The sample consisted of 28 unfamiliar 20- and 30-month-old toddlers (predominantly White, 16 males) who met separately with each of two other toddlers for 18 play dates. The frequency of games increased over time, while the frequency of conflict and contingency sequences decreased. The length of games increased over time while the length of conflicts and contingency sequences were stable. Age and language ability predicted changes in frequency and length of the different types of sequences. Thus, toddlers engage in less structured interactions when they first meet; their interactions become increasingly more organized and positive as the relationship evolves.

Gender and contextual variations in self-perceived cognitive competence

School performance and cognitive competence can be conceptualized as social and relational constructs. Thus, we expect their association to vary as a function of other socially-embedded variables which have proven meaningful in the academic domain. The present study takes a critical theory approach to assess gender-related and contextual variability in the association between peer-assessed school performance and self-perceived cognitive competence. The sample consisted of 719 preadolescents (M age = 9.5 years, range = 9 to 12.5 years) living in lower- and upper-middle-class neighborhoods in Montreal, Canada and Barranquilla, Columbia. Multigroup comparisons revealed that (a) peer-assessed school competence was more strongly associated with self-perceived cognitive competence for upper-middle-class than lower-middle-class participants from Barranquilla, whereas the opposite pattern was observed with Montreal participants, and (b) that the association between communal orientation and self-perceived cognitive competence was stronger for girls than for boys across the sample, especially in the upper-middle-class school in Montreal. These findings highlight the nuanced degree of gender differences in preadolescents’ perceived academic competence and emphasize the role of SES in shaping self-perceptions.

Positive and negative actions early in the relationship predict later interactions among toddlers

Very little is known about the role of early interactions in the development of peer relationships among toddlers. The present study examined whether behaviors early in the formation of toddler relationships predict interactions later in their relationships. Twenty-eight unfamiliar 20- and 30-month-old toddlers from a predominately European background met separately with each of two other toddlers for 18 playdates. Both positive and negative behaviors at the beginning of the relationship predicted a higher frequency of games later in the relationship. Positive behaviors at the beginning of the relationship predicted fewer conflicts later in the relationship. Negative behaviors at the beginning predicted more conflicts later in the relationship. These findings suggest that toddlers’ behaviors, when they initially meet, underlie the pathway in which their relationship develops.

Psychophysiological adjustment to formal education varies as a function of peer status and socioeconomic status in children beginning kindergarten

The transition to kindergarten can be stressful as children adjust to novel separations from their caregivers and become accustomed to their peer group. A 9-month study of 96 children (M_age  = 5.37 years, SD = 0.42) from Barranquilla, Colombia, assessed socioeconomic differences in hypothalamic-pituitary-adrenal (HPA) axis functioning across the kindergarten year. Children were from four different classrooms in one school. Saliva samples were collected twice a day across 3 consecutive days at the beginning and end of the school year. We examined whether change in HPA axis activation across the year varied as a function of a child's socioeconomic status (SES) and experience in the peer group. We found that rejected children and lower SES children had lower cortisol levels early in the morning. Rejected children had a flatter morning cortisol slope. Lower SES children had higher cortisol than their higher SES peers at the end of the school year and a flatter morning cortisol slope. Taken together, these findings suggest that diurnal cortisol in children beginning kindergarten may be influenced by both peer rejection and SES.

Associations between interpersonal behavior and friendship quality in childhood and adolescence: A meta-analysis

This meta-analysis examined concurrent associations between aggression, withdrawal, assertion, and prosocial behavior and each of positive and negative friendship quality across studies with 22,657 children and adolescents (M_age  = 11.71 years; 51.7% girls; 67.7% White). Studies were published between 1995 to 2021 and 32.4% were conducted outside of North America. Aggression was linked to more negative, r ¯  = .19, 95% CI [.14, .24], and less positive, r ¯  = -.05 [-.08, -.01], friendships. Withdrawal was associated with less positive friendships, r ¯  = -.13 [-.18, -.08], whereas prosocial behavior was related to more positive, r ¯  = .29 [.22, .37], as well as less negative, r ¯  = -.16 [-.20, -.12], friendships. Assertion was related to more positive friendships, r ¯  = .15 [.01, .28].

Replication studies of critical findings from the peer literature: An introduction

Despite its importance, replication has remained in the background of social development research. The aim of this special section was to elucidate and elevate the role of replication in peer relations research, examining its challenges and its utility for moving the field forward. To accomplish this aim, five sets of researchers undertook identifying an important finding from a widely cited article in the peer literature and tried to replicate its basic results using new data. As a group, the resulting five articles cover a broad range of topics, measures, and methods that are seen in peer research. Four of the five articles provide evidence of replication. This evidence was seen more for basic principles or processes observed in earlier studies than for exact or specific findings. In addition, the authors used varied approaches to replication, highlighting the need to embrace diverse methods when attempting to replicate complicated mechanisms of social development. It is argued that replication efforts should be aimed at identifying basic principles and processes of social development while clarifying the parameters that account for variability across studies in the specific findings.

Contextual variations in associations between measures of aggression and withdrawal and functioning with peers: A replication study

Data from 790 older school-age (Mage = 10.2 years, SD = 1.2 years) girls (N = 427) and boys from Barranquilla, Colombia (N = 449) and Montréal, Canada (N = 331) were used to replicate findings reported by Valdivia et al. (2005). This prior study revealed contextual variations in the association between two measures of social behavior, specifically aggression and withdrawal, and two measures of effective functioning with peers, specifically sociometric preference and friendship. The Montréal participants were primarily from families with European backgrounds. The ethnicity of the participants from Barranquilla can be described as Latinx/Caribbean. Multilevel analyses provided evidence of replication of place differences only for the associations between measures of aggression and sociometric preference. Stronger negative associations were observed between (a) measures of aggression and sociometric preference, (b) measures of withdrawal and sociometric preference, and (c) withdrawal and friendship in peer groups that were high in collectivism. These findings are interpreted as largely replicating the deep structure of the findings from the Valdivia et al. study. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

The effect of classroom aggression-related peer group norms on students' short-term trajectories of aggression

Using a four-wave/seven-month longitudinal design with a sample of 1595 preadolescents (53% boys, 47% girls, M_age  = 10.2 years) from 63 fourth-, fifth- and sixth- grade classrooms in nine mixed-sex schools in Bogotá, Colombia, we examined whether growth trajectories of measures of overt and relational aggression varied as a function of classroom norms for aggression. Multilevel growth mixture modeling revealed (a) distinct trajectories of overt and relational aggression for boys and girls and (b) that norm salience (i.e., the process by which a group norm is made salient via the punishments or reinforcements to the behavior within the group) was a better predictor of associations with trajectories of overt and relational aggression than were perceived injunctive norms (i.e., the perceived standards of what is approved or disapproved in a social context). In classrooms where popular or accepted children were perceived by their peers as aggressive, more boys followed an increasing trajectory of overt and relational aggression than a low-stable trajectory, and more girls followed a high-stable trajectory of relational aggression than a low-stable trajectory. These findings are discussed in terms of the practical implications for the design of educational interventions aimed at preventing aggression in classroom settings.

Gender is Key: Girls' and Boys' Cortisol Differs as a Factor of Socioeconomic Status and Social Experiences During Early Adolescence

The risks associated with negative peer relationships and low socioeconomic status (SES), and how they impact diurnal cortisol and the cortisol response to negative experiences, have never been studied together in early adolescents; this study aims to fill this gap in the literature. Saliva was collected from 95 early adolescents (M_age = 10.80, SD = 0.72) and daily diaries were completed 30 min after awakening, beginning of school, 15 min after first recess, 15 min after lunch, and at the end of the school day across four consecutive days. Hierarchical Linear Modelling was used to estimate the within- and between-person variances of diurnal cortisol and the cortisol response to stress in the context of SES and peer experiences. Cortisol secretion differed by gender and was predicted by SES and social status within the peer group. Low-SES early adolescents had higher morning cortisol. Girls who were from higher SES families had the steepest diurnal cortisol slope. Non-accepted early adolescents had low cortisol in response to both positive and negative social experiences. The findings from this study clarify the impact of both SES and peer relations on early adolescent psychophysiological development.

Peer relations and socioeconomic status and inequality

Although peer relations are recognized as a fundamental developmental context, they have been rarely studied as a means of understanding the effects of socioeconomic status and inequality. In this paper, we show how and why peer relations provide a unique and powerful opportunity to assess the differential risks and resources available in the peer system to children and adolescents from different SES spectra. We argue that research on the intersection between SES and peer relations will enrich both these domains of study.

Studying the Same-Gender Preference as a Defining Feature of Cultural Contexts

Research on culture would be enriched by studying the connection between gender and peer relations. Cultures vary in the roles, privileges, opportunities, and right that are ascribed to girls and boys. They are known to also differ in the degree to which girls and boys interact with each other. Although the preference for same-gender peers has been observed across multiple cultural contexts, the degree of this segregation between girls and boys varies across contexts. We argue that variability in the divide between girls and boys is an important cultural feature of contexts that is likely to affect developmental processes and outcomes.

Evidence Base Update for Measures of Social Skills and Social Competence in Clinical Samples of Youth

Social skills and social competence are key transdiagnostic processes in developmental psychopathology and are the focus of an array of clinical interventions. In this Evidence Base Update, we evaluated the psychometric properties of measures of social skills and social competence used with clinical samples of children and adolescents. A systematic literature search yielded eight widely used measures of social skills and one measure of social competence. Applying the criteria identified by Youngstrom et al. (2017), we found that, with some exceptions, these measures had adequate to excellent norms, internal consistency, and test-retest reliability. There was at least adequate evidence of construct validity and treatment sensitivity in clinical samples for nearly all measures assessed. Many of the scales included items assessing constructs other than social skills and competence (e.g., emotion regulation). Development of updated tools to assess youth's effectiveness in key interpersonal situations, including those occurring online, may yield clinical dividends.

Being fun: An overlooked indicator of childhood social status

OBJECTIVE

The present study concerns an overlooked trait indicator of childhood peer status: Being fun. The study is designed to identify the degree to which being fun is uniquely associated with the peer status variables of likeability and popularity.

METHOD

Two studies of children in grades 4 to 6 (ages 9 to 12) are reported. The first involved 306 girls and 305 boys attending school in northern Colombia. The second involved 363 girls and 299 boys attending school in southern Florida. Students completed similar peer nomination inventories, once in the first study and twice (8 weeks apart) in the second.

RESULTS

In both studies, being fun was positively correlated with likeability and popularity. In the second study, being fun predicted subsequent changes in likeability and popularity, after controlling for factors known to be related to each. Initial likeability and popularity also predicted subsequent changes in perceptions of being fun.

CONCLUSIONS

Anecdotal evidence suggests that children are intensely focused on having fun. The findings indicate that this focus extends beyond the immediate rewards that fun experiences provide; some portion of peer status is uniquely derived from the perception that one is fun to be around.

PROMIS Peer Relationships Short Form: How Well Does Self-Report Correlate With Data From Peers?

Objective

To examine the psychometric properties of the Patient-Reported Outcomes Measurement Information System (PROMIS®) peer relationships short form (PR-SF), including association with peer-reported friendships, likeability, and social reputation.

Method

203 children (Mage = 10.12 years, SD = 2.37, range = 6-14) in Grades 1-8 completed the 8-item PR-SF and friendship nominations, like ratings, and social reputation measures about their peers during 2 classroom visits approximately 4 months apart, as part of a larger study. A confirmatory factor analysis, followed by an exploratory factor analysis, was conducted to examine the factor structure of the PR-SF. Spearman correlations between the PR-SF and peer-reported outcomes evaluated construct validity.

Results

For the PR-SF, a 2-factor solution demonstrated better fit than a 1-factor solution. The 2 factors appear to assess friendship quality (3 items) and peer acceptance (5 items). Reliability was marginal for the friendship quality factor (.66) but adequate for the acceptance factor (.85); stability was .34 for the PR-SF over 4 months. The PR-SF (8 items) and acceptance factor (5 items) both had modest but significant correlations with measures of friendship (rs = .25-.27), likeability (rs = .21-.22), and social reputation (rs = .29-.44).

Conclusions

The PR-SF appears to be measuring two distinct aspects of social functioning. The 5-item peer acceptance scale is modestly associated with peer-reported friendship, likeability, and social reputation. Although not a replacement for peer-reported outcomes, the PR-SF is a promising patient-reported outcome for peer relationships in youth.

Contextual variations in children’s perceptions of their peers as gender typical

Cultural and socioeconomic differences in children’s perceptions of their peers as being typical members of the cis gender group were examined in a cross-sectional sample of 351 girls ( N = 164) and boys from 19 fifth- and sixth-grade classrooms (M age = 11.5) in three primary schools in Montréal ( N = 156) and two schools in Barranquilla. Multilevel modeling indicated that: (a) the overall level of perceived typicality was low; (b) boys perceived other boys to be more typical than girls, whereas girls perceived girls and boys to have the same level of typicality; (c) in Barranquilla perceptions of gender typicality were higher among upper-middle-class children than among lower-middle-class children, whereas no difference was observed with the children from Montréal.

Contextual variance and invariance in self-perceived gender typicality and pressure to conform to gender role expectations

Evidence of cultural comparisons of gender-identity-measurement scales is scarce. The present study aims to assess the scalar invariance of two dimensions of a widely used gender identity scale (Egan and Perry’s Multidimensional Gender Identity Inventory) across two cultural contexts. Fourth, sixth, and fifth graders from Barranquilla (Colombia) and Montréal (Canada) ( n = 351) completed an abbreviated, self-report revised version of Egan and Perry’s scale. A Confirmatory Factor Analysis demonstrated that typicality and pressure to conform to traditional gender roles are distinct factors and tend to be stable over time. Furthermore, a multi-group comparison analysis showed that the measurement model did not vary significantly as a function of cultural context. Our study adds evidence to support the use of a reliable and valid measurement instrument that is invariant across cultural settings, to allow comparisons that do not depend on contextual variations in the assessment of gender identity during childhood.

Pages from a sociometric notebook: Reconsidering the effects of selective missingness

The effects of selective missingness on the size of observed correlations between scores derived from peer assessment procedures were examined with a sample of 719 boys and girls drawn from 57 peer groups in seven schools in Montréal, Québec, Canada or Barranquilla, a city on the northern Caribbean coast of Colombia in Latin America. Peer groups (i.e., the boys or girls within in a school classroom) in which participation rates exceeded 90% were randomly assigned to either a “complete” or a “missing” group. In separate procedures, children whose scores placed them above the 20th percentile for their group were excluded from the “missing” groups on measures of passive withdrawal, popularity, and aggression. When the correlations observed with the “complete” groups were compared with the correlations observed with the “missing” groups, few differences were observed. These findings are discussed within the context of the effects of missing data on peer assessment techniques and the factors underlying the association between different peer assessment measures.

Daily Affect and Self-Esteem in Early Adolescence: Correlates of Mean Levels and Within-Person Variability

Emotions and self-esteem are critical components of well-being and adaptation during adolescence. People differ in their average levels of affect and self-esteem, as well as in how much their affect and self-esteem fluctuate from moment to moment. Fluctuations in affect in particular have not been extensively examined in relation to adolescent-relevant variables. The present study investigates internalizing symptoms, social functioning, and overt and relational aggression as correlates of average levels and within-person variability in daily positive and negative affect (PA and NA) and self-esteem. Crucially, unique association were examined controlling for the other variables. Early adolescents (mean age 10.8 years, N = 94) completed daily diaries across four days on PA, NA, and self-esteem. They also completed general questionnaires, as did peers. Some key findings were that more internalizing symptoms were significantly associated with more variability in NA. The importance of peer relationships for adolescents' daily mean levels of PA and NA were shown. Peer-perceived social functioning was associated with less fluctuations in self-esteem. Some unexpected, non-significant, findings for aggression appeared. Finally, higher mean NA were associated with more NA fluctuations, whereas higher mean PA and self-esteem were associated with less fluctuations.

Self-Continuity Moderates the Association Between Peer Victimization and Depressed Affect

Two longitudinal studies conducted with early adolescents (ages 10-13) examined the hypothesis that self-continuity, or the degree to which individuals feel that they remain the same person over time regardless of how their specific characteristics may change, would moderate the association between victimization and depressed affect. Both Study 1 (N = 141) and Study 2 (N = 100) provided evidence of the moderating role of self-continuity as a buffer on the effect of peer victimization. Study 2 confirmed that self-continuity had a moderating effect after controlling for academic performance, number of friends, self-esteem, self-concept clarity, hopelessness, and self-blame. Findings support self-continuity as being protective with regard to negative peer environments.

Friendship Security, But Not Friendship Intimacy, Moderates the Stability of Anxiety During Preadolescence

A two-wave longitudinal study of 380 preadolescents (M age = 10.87) from largely middle-class schools in Montréal, Québec, Canada, assessed the hypothesis that friendship security, but not friendship intimacy, moderates the stability of anxiety during adolescence. This central but largely overlooked question about peer relations concerns which aspects of friendship account for the effects of friendship on emotional adjustment. Anxiety and friendship quality were measured via self-report questionnaires, employing the Network of Relationships Inventory for security and intimacy items. An index of friendship durability, which combined reciprocity and stability within first- and second-best friendship choices, was derived from sociometric measures. A latent variable path analysis examined with structural equation modeling showed that anxiety was less stable for children who perceived their friendships as secure. The moderating effect of intimacy was statistically nonsignificant. A follow-up analysis showed that the effects of security did not result from friendship durability. These findings provide support for the long-standing but previously unaddressed hypothesis that security, rather than intimacy, accounts for friendship's effect on anxiety reduction during early adolescence.

The Current Status of Peer Assessment Techniques and Sociometric Methods

Current issues in the use of peer assessment techniques and sociometric methods are discussed. Attention is paid to the contributions of the four articles in this volume. Together these contributions point to the continual level of change and progress in these techniques. They also show that the paradigm underlying these methods has been unchanged for decades. It is argued that this domain is ripe for a paradigm change that takes advantage of recent developments in statistical techniques and technology.

Contextual influences on the relations between physical and relational aggression and peer victimization

Previous studies have demonstrated that several contextual factors influence the relationship between aggression and peer victimization in early adolescence, including gender of the same-sex peer group and gender composition of the school. The current study replicated and expanded on this research by examining the moderating influences of gender of the same-sex peer group, same-sex peer group norms, and classroom gender composition in a sample of early adolescents from Barranquilla, Colombia. Multilevel modeling analyses indicated that both relational and physical aggression were positive predictors of peer victimization. Relationally aggressive girls were at a lower risk for victimization while physically aggressive girls were at a higher risk. Relational aggression was a weaker predictor in classes with a larger proportion of girls. Additionally, relational aggression was a weaker predictor in same-sex peer groups with a greater prevalence of relational aggression. These findings provide further evidence of multiple forms of contextual influence on social behavior. Practical implications for these findings are also provided.

A cross-cultural analysis of the relations of physical and relational aggression with peer victimization

To better address the many consequences of peer victimization, research must identify not only aspects of individuals that put them at risk for victimization, such as aggression, but also aspects of the context that influence the extent of that risk. To this end, this study examined the contextual influences of gender, same-sex peer group norms of physical and relational aggression, and nationality on the associations of physical and relational aggression with peer victimization in early adolescents from Canada, China, Brazil, and Colombia ( N = 865; Mage = 11.01, SD = 1.24; 55% boys). Structural equation modeling was used to test for measurement invariance of the latent constructs. Multilevel modeling revealed that both forms of aggression were positive predictors of peer victimization, but physical aggression was a stronger predictor for girls than boys. Cross-national differences emerged in levels of peer victimization, such that levels were highest in Brazil and lowest in Colombia. Cross-national differences were also evidenced in the relationship between relational aggression and victimization: the relationship was positive in China, Brazil, and Canada (listed in descending order of magnitude), but negative in Colombia. Above and beyond the cross-national differences, physical aggression was a stronger predictor of victimization in peer groups low in physical aggression, and relational aggression was a stronger predictor in peer groups low in relational aggression. Ultimately, this research is intended to contribute to a better theoretical understanding of risk factors for peer victimization and the development of more effective and culturally-appropriate prevention and intervention efforts.

Factors that promote and impede other-sex friendships: a qualitative study of Iranian adolescent girls

AIM

The aim of this study was to identify factors that promote and impede other-sex (OS) friendships in adolescent girls.

METHODS

A qualitative study conducted with 20 adolescent girls recruited in public places in Tehran, Iran. Information was collected through semi-structured interviews and coded via the conventional qualitative content analysis approach.

RESULTS

Four factors were identified that appeared to promote entry into OS friendships. These factors include (a) a poor understanding of perceived risks, (b) weak religious beliefs, (c) processes of identity formation, and (d) low self-esteem. In addition, six factors appeared to impede entry into these friendships: (a) self-confidence, (b) prioritizing education, (c) maintaining particular entertainment preferences, (d) awareness of prior unpleasant experiences with boys, (e) having strong religious convictions, and (f) shaming from significant others.

CONCLUSION

These findings provide unique insights into the factors that stem from different levels of social complexity, which affect participation in a fundamental form of human experience.

Attribution of human characteristics and bullying involvement in childhood: Distinguishing between targets

This investigation researched the association between the attribution of human characteristics and bullying involvement in children by distinguishing between targets. Study 1 focused on the attribution of human characteristics by bullies, victims, bully/victims, and non-involved children toward friends and non-friends. The data from 405 children (M = 10.7 years old) showed that they attributed fewer prosocial and more antisocial human characteristics to non-friends than to friends. Moreover, boy victims attributed fewer prosocial human characteristics to non-friends than boy bullies and non-involved boys did. In addition, victims attributed more antisocial human characteristics to non-friends than non-involved children did. Study 2 addressed bullies', victims', bully/victims', and non-involved children's attribution of human characteristics to each other. The data of 264 children (M = 10.0 years old) showed that bullies, victims, and bully/victims attributed fewer prosocial and more antisocial human characteristics to each other than to non-involved children. Non-involved children attributed fewer prosocial human characteristics to bully/victims than to bullies and victims, and more antisocial human characteristics to bully/victims than to victims. In addition, girls attributed more prosocial and fewer antisocial human characteristics to girls than to boys, whereas boys did not distinguish between girls and boys. Based on these findings, suggestions for future research are provided and implications for bullying prevention and intervention are discussed. Aggr.

Recent advances in the study of development, social and personal experience, and psychopathology

The field of developmental psychopathology has been challenged by various issues in understanding the link between social experiences and psychopathology. These challenges involve conceptual, methodological and statistical concerns that are often interrelated. This article examines four advances in resolving these concerns. First, co-rumination and deviancy training are discussed as specific interpersonal processes that are examples of important social experiences for predicting psychopathology. Second, dynamic properties of dyadic interaction are discussed as one of the recent advances in methodology for this area. Third, the Actor-Partner Interdependence Model is outlined as one of the recent statistical advances in the study of individuals within a dyad. Fourth, changes in the study of culture are presented as informing the understanding link between social experiences and developmental psychopathology.

Stability of aggression during early adolescence as moderated by reciprocated friendship status and friend’s aggression

The effect of friendship reciprocation and friend aggression on the stability of aggression across a 6-month period following the transition to secondary school was studied in a sample of 298 Grade 6 children from a predominately white, middle-class, Midwestern American community. The stability of aggression was generally high but it varied as a function of (1) the level of aggression of both individuals in the friendship and (2) whether the friendship was reciprocated. For children with high initial levels of aggression, those with unreciprocated aggressive friends were the most stable in their aggression. For children with low initial levels of aggression, most children remained stably low in aggression, with type of friendship and friend aggression having little effect on stability. Adolescents who were high in aggression at time 1 (T1) and had an aggressive friend (reciprocated or not) remained aggressive at time 2 (T2), but those who were aggressive at T1 and had nonaggressive friends actually displayed much lower levels of aggression at T2. The opposite did not occur for those adolescents low in aggression at T1. Those low in aggression with aggressive friends at T1 did not increase in aggression. These findings were discussed in light of current thinking about the effect of friendship on development.

Male Iranian adolescent's reasons for having an other-gender friend

AIM

The aim of this study was to identify the primary reasons why male Iranian adolescents enter into other-gender friendships.

METHODS

A qualitative study was conducted with a sample of 21 male adolescents recruited in public places in Tehran, Iran. Information about each boy's experiences with other-gender friends was collected via semi-structured interviews whose contents were analyzed with a conventional qualitative content analysis approach.

RESULTS

Five reasons were identified for engaging in other-gender friendships: (a) for the purpose of entertainment, (b) financial benefits, (c) increased popularity with peers, (d) sensation seeking and (e) sexual experiences.

CONCLUSION

This study revealed that adolescent males do not follow appropriate goals for communicating with the other-gender. In many cases, these goals could endanger their own health and the health of their other-gender friends. Future researchers must focus on identifying and understanding the factors that influence an adolescent to enter into an other-gender friendship.

Adolescent friend similarity on alcohol abuse as a function of participation in romantic relationships: Sometimes a new love comes between old friends

This study tests the hypothesis that adolescents with romantic partners are less similar to their friends on rates of alcohol abuse than adolescents without romantic partners. Participants (662 girls, 574 boys) ranging in age from 12 to 19 years nominated friends and romantic partners, and completed a measure of alcohol abuse. In hierarchical linear models, friends with romantic partners were less similar on rates of alcohol abuse than friends without romantic partners, especially if they were older and less accepted. Follow-up longitudinal analyses were conducted on a subsample (266 boys, 374 girls) of adolescents who reported friendships that were stable across 2 consecutive years. Associations between friend reports of alcohol abuse declined after adolescents became involved in a romantic relationship, to the point at which they became more similar to their romantic partners than to their friends.

Disorders of Sex Development (DSD): Peer Relations and Psychosocial Well-Being

Social and emotional development is shaped by familial and extra-familial experiences especially interactions with peers. Children and adolescents with physical, behavioral or developmental differences, such as youth with disorders of sex development (DSD), may not benefit to the same degree as other children and adolescents from experiences with peers. This paper reviews current thinking about the features and effects of experiences with peers and the potential challenges of peer interactions for children and adolescents with DSD. We review findings from studies of adjustment for individuals with DSD. We finish the paper with a brief outline of a research agenda to promote the understanding of adjustment of individuals with DSD.

Knowledge transfer or social competence? A comparison of German and Canadian adolescent students on their socio-motivational relationships in school

This cross-national study investigates the perception of the impact of students’ relationships towards teachers and peers on scholastic motivation in a total sample of 1477 seventh and eighth grade German ( N = 1088) and Canadian ( N = 389) secondary school students. By applying Multigroup Confirmatory Latent Class Analysis in Mplus we confirmed four different motivation types: (1) teacher-dependent; (2) peer-dependent; (3) teacher-and-peer-dependent; (4) teacher-and-peer-independent motivation types in Québec, Canada, as they were found in a preliminary study among German students in the state of Brandenburg ( Raufelder, Jagenow, Drury, & Hoferichter, 2013 ). However, across the two samples, the class sizes varied considerable. The largest group among Canadian students was composed of teacher-and-peer-dependent students, followed by teacher-and-peer-independent students, while the largest group among German students was composed of peer-dependent students, followed by teacher-and-peer-independent students. In both settings the teacher-dependent motivation type constituted the smallest group. These results manifest the different impacts of social environmental variables on the motivation of German and Canadian students, having practical implications for school psychologists and educators in general.

Dehumanization in children: the link with moral disengagement in bullying and victimization

The current study explored subtle dehumanization-the denial of full humanness-in children, using distinctions of forms (i.e., animalistic vs. mechanistic) and social targets (i.e., friends vs. non-friends). In addition, the link between dehumanization and moral disengagement in bullying and victimization was investigated. Participants were 800 children (7-12 years old) from third to fifth grade classrooms. Subtle animalistic and mechanistic dehumanization toward friends and non-friends were measured with the new Juvenile Dehumanization Measure. Results showed that animalistic dehumanization was more common than mechanistic dehumanization and that non-friends were dehumanized more than friends. The highest levels of dehumanization were found in animalistic form toward non-friends and the lowest levels in mechanistic form toward friends. Both moral disengagement and animalistic dehumanization toward friends were positively associated with bullying. However, moral disengagement was negatively associated with victimization, whereas both animalistic and mechanistic dehumanization toward non-friends were positively associated with victimization. The current findings indicate that children are able to distinguish different forms and targets of dehumanization and that dehumanization plays a distinct role from moral disengagement in bullying and victimization.

Opposites detract: middle school peer group antipathies

This study examines variability in patterns of peer group antipathy. Same-grade adolescent peer groups were identified from sociometric nominations of preferred affiliates in a community sample of 600 Finnish ninth-grade middle school students (mean age=15.0 years). Hierarchical linear modeling determined characteristics of youths in actor groups (nominators) that predicted antipathy for youths in target groups (nominatees) on the basis of target group characteristics. Most antipathies were based on dissimilarity between groups representing the mainstream culture and groups opposed to it. The higher a peer group's school burnout, the more its members disliked students in peer groups with higher school grades and students in peer groups with higher sports participation. Conversely, the higher a peer group's school grades, the more its members disliked students in peer groups with higher school burnout. Students in peer groups with less problem behavior disliked students in peer groups with more problem behavior. There was some evidence of rivalry within the mainstream culture: The higher a group's school grades, the more its members disliked groups whose members participated in sports.
