Peer victimization represents a pervasive problem, particularly for students in middle school. Although curriculum-based prevention programs have generated small to moderate effects on victimization, these effects tend to weaken beginning with the transition to middle school. In this study, we evaluated cooperative learning (CL) as a mechanism to prevent victimization, and evaluated reciprocated friendships as a mediator of these effects. Using four waves of data from a cluster randomized trial of CL (7 intervention and 8 control middle schools; N = 1,890 students, 47.1% female, 75.2% White), we found that CL significantly reduced victimization after two years, and these effects were mediated by growth in the ratio of reciprocated friendship in the first year. We conclude that CL can reduce victimization by providing a means for students to engage in extended social interactions with a wider range of peers and thus creating opportunities for students to forge stronger (i.e., reciprocated) friendships.

Adolescents, particularly early adolescents, are vulnerable to stress created by negative peer interactions. Stress, in turn, can lead to increased mental health problems and reduced academic engagement, in addition to negative long-term consequences for cognitive development and physical health. Using four waves (2 years) of data from a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White), we evaluated whether enhancements to peer relations, brought about through carefully structured small-group learning activities (i.e., cooperative learning), could reduce stress and emotional problems and promote academic engagement. We hypothesized that the increased social contact created by cooperative learning would promote greater peer relatedness, reducing student stress and, in turn, reducing emotional problems and promoting academic engagement. Our results confirmed these hypotheses. We conclude that cooperative learning can provide social, behavioral, academic, and mental health benefits for students.

Students with disabilities are at an increased risk of experiencing poorer quality peer relationships than those without disabilities. Previous school-based efforts to promote positive peer interactions among students with and without disabilities have included individual skill development and broader initiatives such as inclusive school practices. In the current study, we investigate the effects of cooperative learning (CL) on peer relationships, peer academic supports, and classroom engagement of middle school students with and without disabilities over two years. Using 4 waves of data from a cluster randomized trial of middle schools, we hypothesized that CL would create positive gains in study outcomes among all students, but we anticipated that effects would be more pronounced among students with disabilities. Results confirmed these hypotheses and highlighted the potential role of CL in creating greater social integration among students with and without disabilities. The implications of these findings for practitioners and policymakers are discussed. [ABSTRACT FROM AUTHOR]

Despite "Brown vs. Board of Education," prejudice still exists in the American school system. These attitudes can give rise to negative social experiences for students of color (i.e., discrimination), negatively impacting their mental and physical health and creating disparities in educational outcomes. Rather than seeking to ameliorate these negative experiences, our approach attempts to address the underlying prejudices and, in so doing, reduce these disparities. Using 4 waves of data from a cluster randomized trial (N = 15 middle schools, 1,890 students, 47.1% female, 75.2% White), we hypothesized that cooperative learning, which has been shown to reduce prejudice in previous research, would create positive gains in peer relatedness, perceptions of academic support, and engagement in learning, and that gains would be larger for students of color; our results confirmed these hypotheses. Our findings highlight the potential role of cooperative learning in reducing disparities and creating greater equity in education.

Background: Adolescent mental health issues are a major public health concern, highlighted by the US Surgeon General as a crisis. Traditional school‐based interventions show inconsistent success, creating a demand for effective solutions. Aims: This study evaluates the impact of technology‐supported cooperative learning (CL) on adolescent mental health, focusing on positive peer relations and peer victimization. Materials and Methods: Participants included 813 adolescents (50.2% female; 70.7% White) from 12 middle and high schools in the Pacific Northwest. The study used hierarchical linear modelling (HLM) to assess the effectiveness of CL facilitated via PeerLearning.net. Results: Implementing CL led to significant improvements in peer relations and reductions in victimization and mental health problems, with moderate‐to‐large effect sizes observed across different demographics. Positive peer relations significantly predicted lower victimization and improved mental health. Discussion: The findings highlight the potential of technology‐supported CL in addressing adolescent mental health by enhancing protective factors and reducing risks. Such interventions offer a scalable and sustainable approach for schools to address mental health challenges. Conclusion: Technology‐supported cooperative learning offers a promising strategy for improving adolescent mental health, demonstrating significant benefits in peer relations and reducing victimization. This approach provides schools with an accessible and effective tool to tackle the mental health crisis among students. [ABSTRACT FROM AUTHOR]

Peer victimization is a highly stressful experience that impacts up to a third of all adolescents and can contribute to a variety of negative outcomes, including elevated anxiety, depression, drug use, and delinquency, as well as reduced self-esteem, school attendance, and academic achievement. Current prevention approaches (e.g., the Olweus program) have a mixed record in American schools. We propose a new approach to prevention that leverages theory and research surrounding the social aspects of bullying and victimization, particularly peer relations. Our approach attempts to (a) break down the process of homophily among bullies and (b) provide a mechanism by which socially isolated students can develop new friendships. Our approach asks teachers to increase opportunities for positive peer interaction through carefully structured, group-based learning activities in school (i.e., cooperative learning). We hypothesized that these positive peer interactions would result in reductions in bullying, victimization, perceived stress, and emotional problems, as well as increases in peer relatedness, among more marginalized students. Using a cluster randomized trial with 15 rural middle schools in the Pacific Northwest (N = 1,460 7th-grade students), we found that cooperative learning significantly reduced bullying, victimization, and perceived stress for marginalized students (i.e., moderated effects) and reduced emotional problems and enhanced relatedness for all students (i.e., main effects). Given that cooperative learning has already been shown to enhance student engagement and achievement in prior research, our results demonstrate that cooperative learning should be a permanent, sustainable component of teacher training and school culture.

As children reach adolescence, peer groups gain special power to influence their behavior, and young people tend to adapt their behavior to fit group norms. When students engage in bullying, alcohol and drug abuse, and other behavior, those in their peer group are more likely to engage in those behaviors as well. The authors sought to evaluate whether having students engage in peer learning through interdependent cooperative groups might disrupt this tendency. Middle school teachers were trained in using peer learning to teach their regular curriculum, and after one year, students showed more positive and less negative behavior than those in control schools that did not implement peer learning. The effect was also larger than has been reported for traditional prevention and social-emotional learning programs.

The formation and maintenance of young adult romantic relationships that are free from violence and are characterized by love, connection, and effective problem-solving have important implications for later well-being and family functioning. In this study, we examined adolescent hostile-aggressive behavior (HAB) and family relationship quality as key individual and family level factors that may forecast later romantic relationship functioning. Guided by a family systems framework, we evaluated the reciprocal influences of adolescent hostility and family climate, to provide a more comprehensive picture of the etiology of romantic relationship functioning. We drew on a large sample (N = 974) of young adults (mean age = 19.5) that were followed starting in the fall of 6th grade, and subsequently in spring of 6th, 7th, 8th, 9th, and 10th grades prior to the young adult assessment. Using a latent difference score cross-lag model (McArdle, 2009), our results indicated that a more positive family climate was associated with decreases in HAB, but HAB was not associated with changes in family climate. Further, the influence of the family climate on HAB was consistent across all time points. HAB and family climate had different predictions for young adult romantic relationships: Increasing HAB over adolescence predicted relationship violence, while maintenance in family climate was a key predictor of relationship problem-solving skills. The only predictor of love and connection in relationships was early family functioning. Implications for developmental theory and prevention science are discussed.

Social-emotional learning programs are increasingly being implemented in U.S. schools to address a wide range of problematic behaviors (e.g., bullying, delinquency) and to promote academic success. The current study examined the direct and indirect impact of the Second Step Middle School Program (Committee for Children, 2008) on bullying, cyberbullying, homophobic name-calling, and sexual harassment perpetration over the course of a 3-year randomized clinical trial. Delinquency was examined as an intervening variable between treatment condition and aggression outcomes. Thirty-six schools in Kansas and Illinois were assigned to either a Second Step condition or a control condition, and 3,651 sixth-grade students completed self-reported surveys at four time points across 3 years. Students in the Second Step condition received a total of 41 lessons across the 3-year study. No direct intervention effects were found for multiple forms of aggression perpetration at the end of 3 years. However, as hypothesized, decreases in self-reported delinquency (intervening variable) over the first 2 years were significantly related to decreases in bullying, cyberbullying, and homophobic name-calling perpetration for Second Step schools across the 3-year study. Indirect effects of the Second Step program on bullying and aggressive behavior were statistically significant through reductions of delinquency.

Background: Early substance use co-occurs with youths' self-organization into deviant peer groups in which substance use is central to social interaction. We hypothesized that the social dynamics of deviant peer groups amplify the risk of progressing from early use to later dependence, and that this influence occurs over and above escalations in use that typically accompany early substance use and membership in deviant groups. Methods: Our study used a longitudinal, multimethod dataset consisting of 998 adolescents and their families. Participants were recruited from middle schools in a large metropolitan area in the Pacific Northwest. The sample was 47.3% female and ethnically diverse (42.3% European American, 29.1% African American, and 28.6% other, including biracial). We examined deviant peer clustering as a mediator between early substance use and later dependence, controlling for proximal levels of use, SES, early antisocial behavior, and parental monitoring. Tobacco, alcohol, and marijuana use were assessed at ages 12, 13, and 16-17. Past-year nicotine, alcohol, and marijuana dependence (DSM-IV) was assessed at age 19. Youth and parent reports and observational data were used to assess deviant peer clustering at age 16-17, and youth reported on antisocial behavior and parental monitoring at ages 12 and 13. Results: Early substance use predicted increased likelihood of dependence on tobacco, alcohol, and marijuana by late adolescence. Deviant peer affiliation mediated these links, even when accounting for proximal levels of substance use. Conclusions: Early substance use not only promotes escalations in use across adolescence but also provides entry into a deviant social context that contributes to increased risk of dependence. Our results emphasize the importance of identifying and intervening in early substance use before it becomes an organizing factor in friendship selection and interaction. Deviant peer clusters are clearly an important avenue for intervention when seeking to interrupt the progression to substance dependence.

Background: Aggression is one of the more stable characteristics of child and adolescent development, and violent behavior in early adulthood is often foreshadowed by aggressive behavior in childhood and early adolescence. Considerable evidence has linked coercive family interactions to aggressive behavior in childhood, but less research has been conducted on the joint role of family and peer interaction in the escalation of aggression to violence in adulthood. Methods: We coded family interactions at age 12-13 and friendship interaction at age 16-17 in a multiethnic sample of youth and families. Violence in young adulthood (age 22-23) was measured using self-report, criminal records, and parent report. We tested the hypothesis that a process of "coercive joining" in friendship interactions mediated the relationship between coercive family interactions and serious violence. Results: We found that observed coercive joining in friendships at age 16-17 predicted early-adulthood violent behavior over and above an established tendency toward antisocial behavior. We also found that observed coercive family interactions at age 12 predicted early-adulthood violence, and that coercive joining with friends fully mediated this link. Conclusions: These results significantly extend coercion theory by suggesting that coercive joining in the context of peer groups is an additional mechanism by which coercive processes in the family are extended and amplified to violent behavior in early adulthood. Our findings suggest the importance of addressing both individual interpersonal skills and self-organizing peer groups when intervening to prevent violent behavior. (Contains 1 table and 2 figures.)

Objective: This study evaluated the ability of delinquent peer affiliation to mediate the effects of multidimensional treatment foster care (MTFC; Chamberlain, 2003) on girls' delinquent behavior. Method: This study used a sample of girls from 2 cohorts (N = 166; M = 15.31 years old at baseline, range 13-17 years; 74% European American, 2% African American, 7% Hispanic, 4% Native American, 1% Asian, and 13% mixed ethnicity) and measures of delinquent behavior, including general delinquency, number of criminal referrals, and number of days in locked settings. As the mediator, we used self-reports of affiliation with delinquent peers. Our analytic plan specified an intent-to-treat analysis within the framework of a randomized controlled trial comparing MTFC with traditional community-based group care. Results: Random assignment to the MTFC program reduced girls' number of criminal referrals and number of days in locked settings at 24 months. The MTFC condition also reduced girls' exposure to delinquent peers at 12 months, which in turn reduced levels of all forms of delinquent behavior at 24 months; indirect effects were statistically significant. Conclusions: Reduction in exposure to delinquent peers mediated MTFC effects on the number of criminal referrals and number of days in locked settings; delinquent peers also served as an intervening variable between MTFC and self-report delinquency, suggesting that, by reducing contact with delinquent peers, MTFC helped to encourage lower levels of self-report delinquency. Existing prevention and intervention programs targeting similar populations may benefit from increased attention to reductions in delinquent peer affiliation in female samples.

In this study, the validity of a self-report measure of children's perceived attachment security (the Kerns Security Scale) was tested using adolescents. With regards to predictive validity, the Security Scale was significantly associated with (1) observed mother-adolescent interactions during conflict and (2) parent- and teacher-rated social competence. With regards to convergent validity, the Security Scale was significantly associated with all subscales of the Adult Attachment Scale (i.e., Depend, Anxiety, and Close) as measured 3 years later. Further, these links were found even after controlling for mother-child relationship quality as assessed by the Inventory of Parent and Peer Attachment (IPPA), and chi-square difference tests indicated that the Security Scale was generally a stronger predictor as compared to the IPPA. These results suggest that the Security Scale can be used to assess perceived attachment security across both childhood and adolescence, and thus could contribute significantly to developmental research during this period.

Associations between trajectories of depressive symptoms and subsequent tobacco and alcohol use were examined in two samples of girls assessed at age 11.5 (T1), 12.5 (T2), and 13.5 (T3). Two samples were examined to ascertain if there was generalizability of processes across risk levels and cultures. Study 1 comprised a United States-based sample of 100 girls in foster care; Study 2 comprised 264 girls in a United Kingdom community-based sample. Controlling for T1 aggression and T1 substance use, individual variation in intercept and slope of depressive symptoms was associated with tobacco use at T3 in both samples: greater intercept and increases in depressive symptoms increased the risk for T3 tobacco use. A similar pattern of associations was found for alcohol use in Study 1. The replicability of findings for the prediction of tobacco use from trajectories of depressive symptoms suggests potential benefit in identifying girls with elevated depressive symptoms for tobacco use prevention programs, prior to the transition to secondary school.

Although some research suggests that schools can be a source of protective factors for students, the processes by which school environments impact students' behavior, performance and adjustment over time are not clear. Guided by both self-determination theory and hope theory, this article evaluated reciprocal effects among adolescent perceptions of the school environment, engagement in learning, hope, and academic achievement. Using a sample of 423 students (M age 15.72 years; 46.7% female; 77.6% white; 30.9% eligible for FRPL) from five small secondary schools in the upper Midwest, students' perceptions of the school environment were linked to engagement in learning, which, in turn, was linked to change in academic achievement and hope over the span of 1 year. Evidence was found for reciprocal links between earlier levels of engagement and hope and later perceptions of the environment. These results suggest that the school environment represents a potential leverage point for educational reform, and interventions that target students' perceptions of autonomy, teacher/peer support, and goal orientation may be able to promote engagement, hope, and academic achievement. In addition, such changes may create a positive feedback loop in which change in academic performance and adjustment accelerate over time. (Contains 3 tables and 2 figures.)

Children of ages 3 to 4.5 years (N = 107; 45 boys, 62 girls) were studied twice, 6 months apart, to examine whether the cortisol rise in child care at Time 1 (T1) was associated with (a) changes in anxious, vigilant behavior from T1 to Time 2 (T2) and (b) higher internalizing symptoms at T2. Controlling for measures of home environment and child care quality at T1, as well as for cortisol activity at T2, we obtained results indicating that behavioral inhibition moderated the associations between the rise in cortisol at T1 and child outcomes at T2 (i.e., anxious, vigilant behavior and internalizing symptoms). For both outcomes, the rise in cortisol at T1 became more positively predictive at increasing levels of behavioral inhibition. Specifically, at higher levels of behavioral inhibition, children with larger T1 cortisol increases expressed more internalizing symptoms than did children at lower levels of behavioral inhibition; in contrast, for those with low cortisol activity at T1, children with higher levels of inhibition expressed fewer internalizing symptoms than did children at lower levels of inhibition. In addition, children with higher levels of behavioral inhibition and lower cortisol activity at T1 exhibited reductions in anxious, vigilant behavior from T1 to T2, whereas at lower levels of behavioral inhibition, variations in the T1 cortisol rise bore no relation to changes in this behavior. These results suggest that the rise in cortisol at child care may have differential predictive value as a function of behaviorally inhibited temperament. (Contains 4 tables and 2 figures.)

Background: Experience in institutional/orphanage care has been linked to increased mental health problems. Research suggests that children adopted from institutions experience specific difficulties related to inattention/overactivity. Evidence of internalizing and conduct problems relative to non-adopted peers has been found in early childhood and early adolescence, but problems may not differ from other adopted children. This study clarifies the understanding of behavioral and emotional symptoms of post-institutionalized (PI) children during middle childhood. Methods: Eight- to eleven-year-old PI children (n = 68) and two comparison groups, children internationally adopted from foster care (n = 74) and non-adopted children (n = 76), and their parents completed the MacArthur Health and Behavior Questionnaire related to attention-deficit/hyperactivity disorder (ADHD), externalizing, and internalizing symptoms. Group means for symptom level and number of children with symptoms above clinical cutoffs were compared. Results: PI children displayed an increased level of ADHD symptoms per parent report. PI child and parent report indicated a higher number of PI children above clinical ADHD cutoff. Both groups of internationally adopted (IA) children had higher levels of externalizing symptoms relative to non-adopted children, with parent report indicating higher numbers of IA children above the externalizing clinical threshold. Informants differed in their report of internalizing symptoms. Parents indicated that both IA groups displayed increased internalizing symptom levels and greater numbers above clinical threshold; however, children reported this to be true only for the PI group. Conclusions: PI children differ from non-adopted peers across symptom domains in middle childhood. Whether these concerns were more broadly associated with international adoption rather than institutional care depended on symptom domain and informant. An understanding of this variability may be beneficial for treatment and intervention. (Contains 2 tables.)

This study examined the increase in salivary cortisol from midmorning to midafternoon in 151 children (3.0-4.5 years) in full-time home-based day care. Compared to cortisol levels at home, increases were noted in the majority of children (63%) at day care, with 40% classified as a stress response. Observations at day care revealed that intrusive, overcontrolling care was associated with the cortisol rise. For girls, the cortisol rise was associated with anxious, vigilant behavior, while for boys the rise was associated with angry, aggressive behavior. Child behavior did not mediate or moderate relations between care quality and the cortisol rise, except for evidence that boys scoring low on angry, aggressive behavior were more sensitive to variations in warm, supportive care than boys scoring high on this behavior.

"Self-determination theory" emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment, and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support) and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The implications of these findings for secondary schools are discussed.

Many educational researchers have identified issues on classifying schools and some have made use of ad-hoc classification systems in their analyses; however, these solutions are generally one-dimensional, which prohibits them from capturing the full breadth of variation among schools. To understand the amount of variation that exist in schools today, the author calls for the creation of a taxonomy of schools. The ultimate goal of the taxonomy is the creation of a clear and comprehensible categorization system, comprised of multiple, theoretically significant dimensions, that produces relatively homogeneous groups of schools and draws clear lines between the groups. With such a taxonomy one can make valid evaluations and comparisons and achieve a real understanding of schools. (Contains 15 notes.)

What is needed to judge school effectiveness is a means by which schools can be assessed as "cultures" that create sets of relationships, norms of behaviors, and values and obligations that lead to the development of healthy and productive adults. The Hope Study was originally designed to evaluate whether the educational setting would produce more positive student outcomes than the traditional model of a secondary school. The basic proposition of the model grew out of the theory of adolescent development known as "stage/environment fit," which hypothesizes three core, overarching needs of adolescents: autonomy, belongingness, and competence. According to this theory, a mismatch between these developmental needs of adolescents and the educational environment can result in such negative outcomes as disengagement, dropping out, or behavioral problems. However, a better match between the needs of adolescents and the educational environment should result in higher levels of motivation, engagement, and achievement. In addition, placing students in a more developmentally appropriate environment should have a positive effect on student psychological health. To assess an educational environment, the authors measure the degree to which the school context supports the students' core developmental needs of autonomy, belongingness, and competence. In addition to measuring student perceptions of the environment in terms of autonomy, belongingness, and competence, they also gathered data on how students respond to the environment in terms of engagement and psychological health. In this article, the authors present convincing evidence that focusing on these needs is not at odds with No Child Left Behind's focus on raising student achievement. (Contains 16 endnotes.)

Introduction: This research investigated how peer victimization and support are reciprocally related and how Cooperative Learning (CL) can reverse the progressive cascade that, unchecked, can culminate in youth mental health problems. Methods: The sample (N = 1890; 53% male) was derived from a randomized trial of CL in 15 middle schools in the United States. Students were recruited in the 7th grade. Structural Equation Modeling (SEM) was used to fit our cross‐lag difference score model across four waves of data. Results: The results indicated a reciprocal relationship between peer support and victimization across time, suggesting the potential for negative experiences with peers to become amplified over time in a "vicious cycle," negatively impacting mental health. Students in intervention schools reported significantly higher levels of peer support and lower levels of victimization, suggesting that CL can intervene in this cycle, with salutary effects on mental health; CL also demonstrated direct effects on mental health. Conclusions: The present study indicates that low peer support can be both a precursor to and an outcome of victimization, serving to maintain a vicious cycle that compounds negative effects on student mental health. Further, results demonstrate how CL can reverse this cycle. We conclude that CL can be of particular importance to the prevention field as a universal mental health program that does not require the associated stigma of identifying youth at elevated risk for referral to treatment programs.
