Extracurricular Activities and Adolescent Development

Abstract: In this article, we summarize: (a) the arguments linking participation in structured leisure activities to positive youth development, (b) our findings on the association of extracurricular activity involvement with both educational and risky behavior outcomes during adolescence and young adulthood, and (c) our findings regarding possible mediating mechanisms of these associations. Participants in most extracurricular activities achieved better educational outcomes than non-participants even after controlling for social class, gender, and intellectual aptitude. Participation in service and religious activities predicted lower rates of drinking and drug use. Participation on school sports teams predicted both better educational outcomes and higher rates of drinking. The mediating mechanisms we discuss relate to identity formation, peer group membership, and attachment to non-familial adults.

Does Peer Ability Affect Student Achievement

Abstract: Empirical analysis of peer effects on student achievement has been open to question because of the difficulties of separating peer effects from other confounding influences. While most econometric attention has been directed at issues of simultaneous determination of peer interactions, we argue that issues of omitted and mismeasured variables are likely to be more important. We control for the most important determinants of achievement that will confound peer estimates by removing student and school-by-grade fixed effects in addition to observable family and school characteristics. The analysis also addresses the reciprocal nature of peer interactions and the interpretation of estimates based upon models using past achievement as the measure of peer group quality. The results indicate that peer achievement has a positive effect on achievement growth. Moreover, students throughout the school test score distribution appear to benefit from higher achieving schoolmates. On the other hand, the variance in achievement appears to have no systematic effect. Copyright © 2003 John Wiley & Sons, Ltd.

Peer rejection and social information-processing factors in the development of aggressive behavior problems in children.

Abstract: The relation between social rejection and growth in antisocial behavior was investigated. In Study 1,259 boys and girls (34% African American) were followed from Grades 1 to 3 (ages 6-8 years) to Grades 5 to 7 (ages 10-12 years). Early peer rejection predicted growth in aggression. In Study 2,585 boys and girls (16% African American) were followed from kindergarten to Grade 3 (ages 5-8 years), and findings were replicated. Furthermore, early aggression moderated the effect of rejection, such that rejection exacerbated antisocial development only among children initially disposed toward aggression. In Study 3, social information-processing patterns measured in Study 1 were found to mediate partially the effect of early rejection on later aggression. In Study 4, processing patterns measured in Study 2 replicated the mediation effect. Findings are integrated into a recursive model of antisocial development.

Examination of Peer-Group Contextual Effects on Aggression during Early Adolescence

Abstract: Peer group contextual effects of aggressive behavior among middle school students (6th-8th graders) were examined using a short-term longitudinal design. More specifically, the homophily hypothesis that peer group membership influences individual-level bullying and fighting was evaluated with multilevel sex-specific models of individual- and peer-level aggression scores. Peer groups were identified via social network analysis. Intraclass correlation coefficients yielded through hierarchical linear modeling demonstrated substantial within-group similarity on self-reported bullying and fighting, suggesting that students affiliate with individuals who bully and fight at the same frequency. Peer group bullying and fighting was associated with individual-level behavior, even after controlling individual baseline levels for males and females. However, peer contextual effects explained more variance in individual bullying than individual fighting. This differential impact of peer group membership suggests that future studies consider peer relations across subtypes of aggression.

Peers and adolescent smoking.

Abstract: There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths’ smoking behavior. Understanding these processes of influence is key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents’ use of tobacco, in some cases promoting use, and in other cases deterring it. This review also suggests that peer influences on smoking are more subtle than commonly thought and need to be examined more carefully, including consideration of larger social contexts, e.g. the family, neighborhood, and media. Recommendations for future investigations are made, as well as suggestions for specific methodological approaches that offer promise for advancing our knowledge of the contribution of peers on adolescent tobacco use.

The Role of Chronic Peer Difficulties in the Development of Children's Psychological Adjustment Problems

Abstract: A longitudinal investigation was conducted to explicate how the confluence of early behavioral dispositions, relational histories, and cognitive representations of the self and others contributes to internalizing problems, externalizing problems, and loneliness. One-hundred and ninety three girls, and 206 boys were assessed annually from age 5 (kindergarten) to age 10 (Grade 4). Early aggressive behavior was related to Grade 4 maladjustment directly and indirectly through subsequent relational stressors. Significant associations emerged between chronic friendlessness and rejection and later adaptation not accounted for by concurrent relational difficulties. Self- and peer beliefs partially mediated the relation between peer difficulties and internalizing problems and loneliness. The results highlight the utility of child-by-environment models as a guide for the investigation of processes that antecede psychosocial maladjustment.

Consequences of Bullying in Schools

Abstract: For the most part, studies of the consequences of bullying in schools have concentrated upon health outcomes for children persistently bullied by their peers. Conclusions have been influenced by how bullying has been conceptualized and assessed, the specific health outcomes investigated, and the research method and data analysis employed. Results from cross-sectional surveys suggest that being victimized by peers is significantly related to comparatively low levels of psychological well-being and social adjustment and to high levels of psychological distress and adverse physical health symptoms. Retrospective reports and studies suggest that peer victimization may contribute to later difficulties with health and well-being. Longitudinal studies provide stronger support for the view that peer victimization is a significant causal factor in schoolchildren's lowered health and well-being and that the effects can be long-lasting. Further evidence from longitudinal studies indicates that the tendency to bully others at school significantly predicts subsequent antisocial and violent behaviour.

Understanding the Influence of Perceived Norms on Behaviors

Abstract: Although a number of studies demonstrate the impact of perceived norms on human behavior we know little about how this relation works. Extant norms-based campaigns to reduce alcohol consumption among U.S. college students fail to distinguish between descriptive and injunctive norms. In this article we make this distinction and we develop a model of normative influences that also includes the impact of group identity and communication patterns of students alcohol consumption. Based on a survey of college students (N = 353) we found that descriptive and injunctive norms were different in terms of their impact on behavior. Furthermore the inclusion of group identity and communication patterns significantly added to the explanatory power of our model. Overall we were able to explain roughly 53% of the variance in consumption. (authors)

Peer interaction and loneliness in high-functioning children with autism.

Abstract: Social interaction with peers and the understanding and feelings of loneliness were examined in 18 high-functioning children with autism and 17 typically developing children matched for IQ, chronological age, gender, and maternal education. Observations were conducted on children's spontaneous social initiations and responses to their peers in natural settings such as recess and snack time, and children reported on their understanding and feelings of loneliness and social interaction. Overall, children with autism revealed a good understanding of both social interaction and loneliness, and they demonstrated a high level of social initiation. However, they spent only half the time in social interactions with peers compared with their matched counterparts, and they interacted more often with a typically developing child than with another special education child. Despite the intergroup differences in frequency of interaction, a similar distribution of interactions emerged for both groups, who presented mostly positive social behaviors, fewer low-level behaviors, and very infrequent negative behaviors. Children with autism reported higher degrees of loneliness than their typical age-mates, as well as a lower association between social interaction and loneliness, suggesting their poorer understanding of the relations between loneliness and social interaction. Research and practice implications of these findings are discussed.

Adolescent Problem Behavior in China and the United States: A Cross‐National Study of Psychosocial Protective Factors

Abstract: An explanatory model of adolescent problem behavior (problem drinking, cigarette smoking, and general delinquency) based on protective and risk factors in the individual and in 4 social contexts (family, peer group, school, and neighborhood) is employed in school-based samples from the People’s Republic of China (N 51,739) and the United States (N 51,596). Despite lower prevalence of the problem behaviors in the Chinese sample, especially for girls, a substantial account of problem behavior is provided by the same protective and risk factors in both countries and for both genders. Protection is generally higher in the Chinese sample than in the U.S. sample, but in both samples protection also moderates the impact of risk. Despite mean differences in psychosocial protective and risk factors, as well as in problem behavior, in the 2 samples—differences that may reflect societal variation— the explanatory model has, to a large extent, cross-national generality.

Bullying Is Power

Abstract: The present investigation examines subtypes of bullies, distinguished on the basis of social power, some of whom fit the traditional characterization of bullies as poorly accepted, psychologically troubled, marginal members of the peer group and others who exhibit a much more positive set of social characteristics and who are afforded high status within the peer group. In a sample of 555 grade 6 to 10 Canadian students, the associations between bullying, power, and social status were examined, as well as variability in bullies across behavioral and non-behavioral characteristics, self-perceptions, and mental health functioning. Peer nominations were used to assess bullying, social status, aggressive behavior, competencies and assets, and self-reports were used to assess social self-perceptions and internalizing difficulties. Results indicated that, although generally viewed by peers as disliked and aggressive, a substantial number of bullies were also seen as both popular and powerful with leader...

Adolescent Oral Sex, Peer Popularity, and Perceptions of Best Friends' Sexual Behavior

Abstract: Objective To provided initial descriptive information regarding adolescents' engagement in oral sex and to investigate adolescents' perceptions of their best friends' sexual behavior and peer-reported popularity as two social mechanisms that may influence engagement in oral sex. Methods A total of 212 tenth graders reported their engagement in oral sex and intercourse, number of sexual partners, and use of sexually transmitted infection (STI) protection, as well as perceptions of their best friends' sexual behaviors. Sociometric assessment yielded peer-reported measures of adolescents' preference- and reputation-based popularity. Results Adolescents were more likely to report engagement in oral sex than intercourse, report more oral sex partners than intercourse partners, and were unlikely to report use of STI protection during oral sex. Perceptions of best friends' behavior were significantly associated with adolescents' own oral sex behavior, but not intercourse. Adolescents who reported sexual activity had high levels of reputation-based popularity, but not likeability among peers; however, sex with more partners was associated with lower levels of popularity. Conclusions Implications for prevention programs are discussed.

The developmental ecology of urban males' youth violence.

Abstract: Data from a longitudinal study of 294 African American and Latino adolescent boys and their caregivers living in poor urban communities were used to test a developmental-ecological model of violence. Six annual waves of data were applied to evaluate the relations between microsystem influences of parenting and peer deviance (peer violence and gang membership), macrosystem influences of community structural characteristics and neighborhood social organization, and individual involvement in violence (level and growth). Structural equation modeling analyses showed that community structural characteristics significantly predicted neighborhood social processes. Parenting practices partially mediated the relation between neighborhood social processes and gang membership. Parenting practices was fully mediated in its relation to peer violence by gang membership. Gang membership was partially mediated by peer violence level in its relation to individual violence level. Although the overall set of relations does not satisfy mediation requirements fully in all instances, the model was validated for the most part, supporting a focus on a multilevel ecological model of influences on risk development.

Late adolescents' self-defining memories about relationships.

Abstract: This study examined late adolescents' self-defining memories about relationships. Participants were 88 European Americans (mean age = 19 years) who reported 3 self-defining memories of their choosing and were selected for the study because they reported a memory about parents and/or peers. Memory narratives were coded for themes of separation, closeness, and conflict and for 2 kinds of meaning: learning lessons and gaining insight. Parent memories emphasized separation more so than peer memories, which emphasized closeness. Within parent memories, however, separation and closeness were equally prevalent. Parent separation was exemplified by experiences of parental divorce, parent closeness by comforting a grieving parent, and peer closeness by episodes of first-time romance. Conflict was more prevalent in parent than peer memories and was associated with meaning-making. Findings are discussed in terms of the usefulness of self-defining memories for illuminating contexts of relationship development in late adolescence and for understanding the emergence of identity and the life story.

Effects of a social-network method for group assignment strategies on peer-led tobacco prevention programs in schools

Abstract: Objectives. Our study tested the effectiveness of network methods for identifying opinion leaders and for constructing groups. Methods. Three conditions—random, teacher, and network—were randomly assigned to 84 6th-grade classrooms within 16 schools. Pre- and postcurriculum data on mediators of tobacco use were collected from 1961 students. Peer leaders in the network condition were identified by student nominations, and those leaders were matched with the students who nominated them. Results. Students in the network condition relative to the random condition liked the prevention program more and had improved attitudes (β = −0.06; P < .01), improved self-efficacy (β = −0.10; P < .001), and decreased intention to smoke (adjusted odds ratio [OR] = 0.46; 95% confidence interval [CI] = 0.38, 0.55). Conclusions. The network method was the most effective way to structure the program. Future programs may refine this technique and use it in other settings.

Peer harassment, school connectedness, and academic achievement.

Abstract: This study described peer harassment in a large, multiethnic sample of adolescents, and explored the relationship between experiencing peer harassment and both school connectedness and achievement. Survey data came from 4,746 students in grades 7-12 at 31 public schools in ethnically and socioeconomically diverse communities in a Midwestern state. Frequency of five types of harassment were analyzed with data on school connectedness and grades. Multivariate analysis controlled for gender, grade level, race/ethnicity, and socioeconomic status. Results indicate that most students periodically experience mistreatment; 10% to 17% report being treated disrespectfully, having others act superior, or being insulted at least once per week, and an additional 14% to 22% of students report suffering these behaviors a few times per month. Girls, Whites, Native Americans, and middle school students reported more harassment than boys, other ethnic groups, and high school students, respectively. Peer harassment related significantly to both aspects of school life; those who disliked school tended to suffer more mistreatment, and "B" students reported the least harassment on average. Young people mistreated by peers may not want to be in school and may thereby miss out on the benefits of school connectedness as well as educational advancement. The high prevalence of peer harassment and its association with school connectedness and school achievement provide justification for interventions aimed at prevention of peer harassment. A schoolwide approach using educational and policy components may provide an appropriate prevention strategy.

Reassessing the Burden of 'acting white': The importance of peer groups in managing academic success

Abstract: In 1986 Fordham and Ogbu introduced the idea that black students continue to underperform in school because of their cultural opposition to acting white. This notion of the burden of acting white and Ogbu's cultural ecological theory more broadly have provided one of the dominant theories used to explain the black-white achievement gap. The research presented here offers a reassessment of the burden of acting white and directs researchers to examine the variation to be found in students' peer groups. This article highlights the ability of students to sustain an authentic black identity and to achieve academically by effectively managing their academic success among their peers

Identifying and Targeting Risk for Involvement in Bullying and Victimization

Abstract: Bullying is a relationship problem in which power and aggression are used to cause distress to a vulnerable person. To assess and address bullying and victimization, we need to understand the nature of the problem, how the problem changes with age and differs for boys and girls, the relevant risk factors (those individual or environmental indicators that may lead to bullying and victimization), and the protective factors that buffer the impact of risk. For children involved in bullying, we need to assess its extent and the associated social, emotional, psychological, educational, and physical problems. Bullying is a systemic problem; therefore, assessments of bullying need to extend beyond the individual child to encompass the family, peer group, school, and community. We recommend that assessments at each of these levels reflect the scientific research on bullying and victimization. With attention to the problems associated with bullying, we can work collectively to make schools and communities safer for children and youth.

Friendship Quality, Peer Group Affiliation, and Peer Antisocial Behavior as Moderators of the Link Between Negative Parenting and Adolescent Externalizing Behavior.

Abstract: Quality of peer relationships and perceived peer antisocial behavior were examined as moderators of the link between negative parenting and externalizing behavior problems in school from middle childhood to early adolescence. Data on negative parenting (i.e., unilateral parental decision making, low supervision and awareness, and harsh discipline) were collected from 362 parents in the summer preceding the adolescents' entry into Grade 6. Adolescent reports of positive peer relationships and peer antisocial behavior were assessed in the winter of Grade 7. The outcome measure was teacher report of adolescent externalizing behavior in the spring of Grade 7, controlling for externalizing behavior in Grade 5. High levels of friendship quality and peer group affiliation attenuated the association between unilateral parental decision making and adolescent externalizing behavior in school; this was particularly true when adolescents associated with peers perceived to be low in antisocial behavior. In addition, having low-quality peer relationships and having peers perceived to be highly antisocial further amplified the association between unilateral parental decision making and adolescent externalizing behavior problems. Finally, high levels of friend and peer group antisocial behavior exacerbated the predictiveness of harsh discipline for adolescents' externalizing behavior.

Adaptation among Youth Facing Multiple Risks: Prospective Research Findings

Abstract: © Cambridge University Press, 2010 and Suniya S. Luthar 2003. The high prevalence of mental health problems among children in the United States has continued to stimulate service-oriented professionals to seek targets for preventive intervention. In a 1999 survey of youth risk behavior during the previous year (Centers for Disease Control and Prevention, 2000), 28% of high school children felt blue or hopeless, 19% had considered suicide, and 8% had made an attempt. In terms of aggression, 36% had been in a physical fight. Academic problems were equally serious, with 30% of Hispanics dropping out before high school graduation compared to 14% of African Americans and 8% of whites. Although the majority of youth do not have such problems, the number who do is substantial. Understanding the pathways that have led to such problem behavior is an important precursor of any successful intervention. Prevention is intimately connected to developmental concerns because there is an expected time course in which activities in the present will influence activities in the future. Where the problem seems to be in the family, school, or peer group, intuitively interventions should take place in those settings and should have immediate impact. Unfortunately, most interventions in single domains have not produced major reductions in problem behavior. It appears that children typically experience multiple risks in multiple social contexts; consequently, it is unlikely that a “magic bullet” for prevention or intervention will be found (Masten & Coatsworth, 1998).

Examining the effectiveness of an outpatient clinic-based social skills group for high-functioning children with autism.

Abstract: Although social skills group interventions for children with autism are common in outpatient clinic settings, little research has been conducted to determine the efficacy of such treatments. This study examined the effectiveness of an outpatient clinic-based social skills group intervention with four high-functioning elementary-aged children with autism. The group was designed to teach specific social skills, including greeting, conversation, and play skills in a brief therapy format (eight sessions total). At the end of each skills-training session, children with autism were observed in play sessions with typical peers. Typical peers received peer education about ways to interact with children with autism. Results indicate that a social skills group implemented in an outpatient clinic setting was effective in improving greeting and play skills, with less clear improvements noted in conversation skills. In addition, children with autism reported increased feelings of social support from classmates at school following participation in the group. However, parent report data of greeting, conversation, and play skills outside of the clinic setting indicated significant improvements in only greeting skills. Thus, although the clinic-based intervention led to improvements in social skills, fewer changes were noted in the generalization to nonclinic settings.

Measuring the impact of health research

Abstract: Measuring the decision-making impact of applied health research should constitute a core function for many research funders and research organizations. Different target audiences warrant different measures of impact. The target audiences for applied health research include the general public, patients (and their families), clinicians, managers (in hospitals, regional health authorities and health plans), research and development officers (in biotechnology firms) and public policy-makers (i.e. elected officials, political staff and civil servants). Making meaningful assessments within peer groups that fund or produce similar types of research knowledge for similar types of target audiences makes more sense than a one-size-fits-all approach to impact assessment. User-pull and interactive measures of impact (i.e. measures of cultural shifts that would facilitate the on-going use of research knowledge to inform decision-making) can supplement more traditional producer-push measures that assess researchers' active efforts to inform decision-making and the outcome of these efforts. Cultural shifts may include the creation of a research-attuned culture among decision-makers and a decision-relevant culture among researchers. Moving beyond whether research was used to examine how it was used is also important. Research knowledge may be used in instrumental, conceptual or symbolic ways. These actions, coupled with on-going refinements to the proposed assessment tool as research evidence evolves, would take us a long way towards assessment and accountability in the health sector.

Contexts of Risk? Explaining the Link between Girls' Pubertal Development and Their Delinquency Involvement

Abstract: Although early and more advanced pubertal development has been linked to adolescent girls' delinquency involvement, the social factors that mediate these relationships have not been established. This study incorporates parent and peer relationship measures from the National Longitudinal Study of Adolescent Health to examine (1) whether parents treat more physically developed daughters differently than their less developed peers, and (2) whether more developed girls are located in friendship networks that are more conducive to delinquency than the networks of less developed girls. Earlier pubertal development and more advanced development are associated with three types of delinquency: "party" deviance, minor delinquency, and serious delinquency. The strength of the association is strongest for "party" deviance (e.g., drinking, smoking, truancy, disorderly conduct). Conflict with parents, trust and autonomy from parents, exposure to peer deviance, and involvement in romantic relationships mediate the puberty-delinquency association. However, the relative importance of each of these mechanisms varies by the context of delinquency and the indicators of pubertal development that are used.

Correlates of unhealthy weight-control behaviors among adolescents: implications for prevention programs.

Abstract: This study aimed to identify correlates of unhealthy weight-control behaviors in adolescents to guide the development of programs aimed at the primary prevention of disordered eating. A model explaining unhealthy weight-control behaviors was tested among 4,746 adolescents using structural equation modeling. Models fit the data well and explained 76% of the variance in unhealthy weight-control behaviors among girls and 63% among boys. Weight-body concerns were a strong correlate of unhealthy weight-control behaviors in both girls and boys. Models also emphasized the importance of weight-specific social norms within the adolescent's proximal environment. Findings suggest the importance of addressing weight-body concerns within prevention programs and extending interventions beyond classroom settings to ensure changes in weight-related norms among peer groups and family members.

Developmental trajectories of boys' delinquent group membership and facilitation of violent behaviors during adolescence

Abstract: Being part of a delinquent group has been shown to facilitate the expression of an individual’s own delinquent propensities. However, this facilitation effect has not been investigated from a developmental perspective within a population heterogeneity model. Using a semiparametric mixture model with data from the Montreal Longitudinal Experimental Study, this article addresses important issues in the developmental trends of membership to delinquent groups. We explore how the rate of violent behaviors follows delinquent peer group trajectories and investigate a differential facilitation effect of delinquent peers on violence across multiple developmental pathways. Results suggest that 25% of males followed a childhood or an adolescence delinquent group affiliation trajectory. These two groups account for most of the violent acts assessed during adolescence. In addition, the rate of violent behaviors follows these developmental trajectories. Controlling for these delinquent group trajectories, we also found that being involved in a delinquent group at any specific time during adolescence is associated with an increased rate of violent behaviors, and that leaving these groups results in a decrease in violent behaviors. This facilitation effect appears homogeneous over time and across developmental trajectories. Results are discussed from a social interactional perspective.
