Forms of Peer Victimization and School Adjustment Among Japanese Adolescents: A Multilevel Analysis.

The psychosocial correlates and consequences of peer victimization are well documented. However, there is limited knowledge about whether different forms of peer victimization (relational and physical) are predictive of school-based social and motivational factors among adolescents from non-Western cultures. The present study examined the relationship between individual and school-level forms of peer victimization and school adjustment among Japanese adolescents, and the mediating role that these factors may play. The Japanese sample (N = 6109 from 185 schools, Mage = 15.78, SD = 0.29, 51% girls and 49% boys) was drawn from a large international dataset, the Organization for Economic Cooperation and Development (OECD) Programme for International Student Assessment (PISA) 2018. Results showed that school-level relational victimization was associated with individual-level relational victimization, and school-level physical victimization was associated with individual-level physical victimization, after controlling for age, gender, and socioeconomic status. Individual-level relational victimization was also uniquely associated with indices of school adjustment (negative affect, positive affect, and fear of failure) over and above physical victimization. While controlling for relational victimization, individual-level physical victimization was associated with indices of school adjustment (positive affect and meaning in life). In further findings, school-level relational and physical victimization were indirectly, but not directly, related to some of students' school adjustment through individual-level relational and physical victimization. These parallel and differential associations suggest the importance of considering the role of relational and physical victimization in school adjustment among Japanese adolescents.

Trajectories and latent classes of school enjoyment in adolescence: Associations with peer victimization and mental health.

School enjoyment, as a measure of how much adolescents enjoy or value their school experience, has been extensively studied in Western cultures. However, our knowledge of school enjoyment, and particularly its changes and trajectories among adolescents living in non-Western cultures, is limited. The present study used 3-year longitudinal data to examine changes and trajectories in school enjoyment and their associations with social and relational factors, such as mental health problems and peer victimization, among Japanese middle school students. Participants were 281 Japanese students from two public middle schools (Time 1 Mage = 12.72, SD = .45, 50% female). Data included five time points at 6-month intervals (Grades 7-9). The growth curve model showed quadratic changes in school enjoyment overall; the mean of school enjoyment was relatively stable in Grades 7 and 8 but increased rapidly in Grade 9. In terms of individual differences in trajectories of school enjoyment, growth mixture modeling identified three distinct groups (i.e., groups of 44.8% increasing, 9.8% decreasing, and 45.4% stable). Compared to students in the other groups, students in the increasing group initially reported lower levels of mental health problems and experienced less relational and overt victimization. In contrast, the decreasing group reported higher levels of mental health problems and experienced more relational and overt victimization than the increasing group. The results inform us about the most adaptive group, which continued to show high levels of school enjoyment, and the most maladaptive group, which initially had lower levels of school enjoyment and decreased their levels over time. The latter group of students is at risk and requires immediate intervention. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

A Longitudinal Study of Forms of Peer Victimization and Internalizing Problems in Adolescence.

The present study examined developmental changes in forms of peer victimization and longitudinal associations between forms of peer victimization and internalizing problems among Japanese adolescents. Participants were 271 students (Time 1 M age = 12.72, SD = 0.45, 50% girls) from 9 classrooms and 2 public middle schools in Japan. Data were collected at five time points from 7th to 9th grade. Growth curve modeling (GCM) of mean changes indicated that relational victimization and internalizing problems decreased over three school years. Overt victimization first decreased and then remained relatively constant toward the end of the assessment. In addition, the results of the Random Intercept Cross-Lagged Panel Model (RI-CLPM) indicated that the random intercept of relational victimization was positively and strongly correlated with that of internalizing problems. Although the random intercept of overt victimization was positively correlated with that of internalizing problems, the effect size was small to moderate. In general, there were no significant within-person changes between relational and overt victimization and internalizing problems. However, some exceptions were noted towards the end of middle school, such that higher relational victimization was associated with increases in internalizing problems, which in turn led to more relational victimization. There were no gender differences in the above trajectories or in the transactional models. The findings regarding at-risk youth who are vulnerable to relational and overt victimization are discussed from clinical, cultural, and developmental perspectives.

Resistance to peer influence, smoking friends, cigarette and betel nut use, and gender among Pacific Islander youth.

The present study examined the relationships between resistance to peer influence and cigarette and betel nut use, as well as the potential mediating role of friends who use cigarettes and betel nut, among boys and girls in Guam. This study included 673 ethnically diverse students (49% female; M age = 12.7, SD = 0.89) from eight public middle schools. The mediation analysis demonstrated that higher resistance to peer influence for both cigarette and betel nut use was associated with lower cigarette and betel nut use directly and that this association was mediated by friends who used cigarette and betel nut products. That is, low resistance to peer influence for both cigarette and betel nut use was associated with a greater number of friends who smoke and use betel nut, which was linked with more cigarette and betel nut use. The moderated mediation analysis revealed no gender difference in the indirect effect (i.e., the mediation of friends who used cigarettes and betel nut). These findings can be used to inform the design and implementation of intervention and prevention programs for at-risk youth, regardless of gender, who are vulnerable to substance use in the Pacific.

A Mediation Model for Biculturalism and Cigarette and Betel Nut Use: The Case of Adolescents in Guam.

The present study examined the associations between biculturalism and cigarette and betel nut use and the potential mediating roles of cigarette and betel nut use risk perception and resistance to peer and adult influence among adolescents in Guam. Participants were 673 ethnically diverse students (49% female; Mage = 12.7, SD = .89) from eight public middle schools. The results showed that biculturalism was not associated with cigarette use directly; however, this association was mediated by cigarette use risk perception and resistance to peer and adult influence. In other words, higher biculturalism was associated with more risk perception and then more resistance to peer and adult influence, which sequentially predicted less cigarette use. Similarly, the association between biculturalism and betel nut use was mediated by betel nut use risk perception and resistance to peer and adult influence. Higher biculturalism was associated with greater risk perception and then more resistance to peer and adult influence, which in turn resulted in less betel nut use. These findings can be used to inform the design and implementation of intervention and prevention programs targeting youth who are vulnerable to substance use.

Types of Offers of Combustible Cigarettes, E-Cigarettes, and Betel Nut Experienced by Guam Youths.

The present study examined types of scenarios in which Guam youths are offered tobacco-namely, combustible cigarettes and e-cigarettes-and betel (areca) nut. We conducted 10 focus groups with public middle school students (n = 34) from Guam. Results suggested that the types of offer scenarios of combustible cigarettes, e-cigarettes, and betel nut referenced by the students fall into two categories-direct-relational offers and indirect-contextual offers. The results also suggested that both categories of offer scenarios were more likely to occur in school rather than in other locations such as the home. Family members were more likely to make offers than other types of people. Indirect-contextual offers were more easily avoidable depending on the substance offered, the location where the offer took place, and the person making the offer. Based on the findings, we provide brief suggestions on developing a school-based prevention curriculum focused on training young adolescents from Guam on ways to resist offers of cigarettes, e-cigarettes, and betel nut.

Guam Adolescents' Use of Strategies to Resist Cigarette, e-Cigarette, and Betel Nut Offers: Findings from a Focus Group Study.

Background: This study examined resistance strategies used by predominantly Pacific Islander young adolescents in response to offers of tobacco, e-cigarettes, and betel [areca] nuts. This study was intended to inform the development of a prevention curriculum focused on training young adolescents from the U.S.-Affiliated Pacific Islands (USAPI) on culturally appropriate strategies to resist substance use offers. Currently, very little is understood in terms of how Pacific Islander youths deal with tobacco and other substance use offers, although the use of tobacco products among Pacific Islander youths is high. Specifically, given the collectivist sociocultural orientation of the Pacific Islander communities, it is unclear whether the direct (overt) confrontational style of resistance is a viable mode of resistance for youths to practice when faced with a substance use offer. Methods: We conducted 10 focus groups with public middle school students (N = 34) from Guam, which is part of the USAPI. Results: Results suggested that, as with other communities in the U.S., the resistance strategies fall into two categories-overt/confrontational and non-confrontational resistance strategies. Overt/confrontational strategies included (a) saying "no" and (b) verbally confronting the offeror. Non-confrontational strategies included (a) avoiding or leaving the situation and (b) telling an adult. Conclusions: Our findings have implications for the development of culturally grounded interventions aimed at preventing youth tobacco and other substance use in Guam, the USAPI, and the Pacific region.

Exposure to tobacco and betel nut content on social media, risk perceptions, and susceptibility to peer influence among early adolescents in Guam.

Introduction: This study aimed to examine the associations between exposure to tobacco and betel nut-related content on social media, perceived risks of tobacco and betel nut use, and susceptibility to peer influence for tobacco and betel nut use among adolescents living in Guam, a United States-Affiliated Pacific Island in the Western Pacific. Methods: A representative survey of adolescents (N = 670) attending public middle schools on Guam was conducted. The survey measured exposure to tobacco and betel nut content on the following social media platforms: (a) Facebook, (b) Twitter, (c) Instagram, (d) Snapchat, and (e) WhatsApp. The survey also measured perceived risks of tobacco and betel nut use and susceptibility to peer influence for tobacco and betel nut use. Results: Guam adolescents' exposure to tobacco-related content on social media was found to be associated with lower perceived risks toward the use of tobacco (ß = -0.18, p < 0.001) and betel nut (ß = -0.16, p < 0.001). Also, exposure to tobacco-related content on social media was found to be associated with higher levels of susceptibility to peer influence for uses of both tobacco (ß = 0.10, p < 0.05) and betel nut (ß = 0.15, p < 0.001). Similarly, exposure to betel nut-related content on social media was associated with lower perceived risks of using betel nut (ß = -0.20, p < 0.001) and tobacco (ß = -0.24, p < 0.001). Also, exposure to betel nut-related content on social media was associated with increased susceptibility to peer influence for use of both betel nut (ß = 0.35, p < 0.001) and tobacco (ß = 0.29, p < 0.001). Conclusions: Adolescents' exposure to tobacco- and betel nut-related content on social media may influence attitudinal risk factors associated with tobacco and betel nut use.

Social media, peer norms, and betel nut susceptibility and use: Evidence from early adolescents in Guam.

Betel (areca) nut is an addictive psychoactive substance considered to be carcinogenic. Yet not much is known about factors that may be promoting betel nut use. To fill this void, the present study examines the roles of exposure to betel nut-related posts on social media and peer norms regarding betel nut use in explaining betel nut susceptibility and use among adolescents. We conducted a representative survey of early adolescents (N = 673) attending all public middle schools on Guam, a United States-Affiliated Pacific Island in the Western Pacific. Results showed that exposure to betel nut-related posts on social media was positively associated with peer descriptive norms regarding betel nut use. Specifically, the more frequent early adolescents were exposed to betel nut posts on social media, the more likely they were to perceive betel nut use to be more prevalent among their general peers and close friends. Additionally, early adolescents' exposure to betel nut-related posts on social media was positively associated with both their susceptibility to use betel nut and reported use. Descriptive norms regarding close friends' betel nut use was also positively associated with both susceptibility to and use of betel nut. However, descriptive norms regarding general peers' betel nut use was unrelated with either betel nut susceptibility or use. Descriptive norms regarding close friends' betel nut use mediated the relationships that exposure to betel nut posts on social media had with both betel nut susceptibility and betel nut use. Implications are discussed.

Measurement of peer and friend relational and physical victimization among early adolescents.

INTRODUCTION: Peer victimization has been widely examined among children and adolescents; however, the majority of studies in the area of research have been conducted in Western cultures. The goal of the present study was to evaluate the utility of measures that assess different forms of victimization (physical and relational victimization; a two-factor model) against a global form of victimization (combined victimization; a one-factor model) in the peer groups and friendships among Japanese adolescents. It was hypothesized that peer and friend relational victimization would be conceptually distinct from peer and friend physical victimization in Japan. METHODS: The participants were fourth and fifth graders (n = 222, 50% females, age 9-11) and their classroom teachers in Japanese elementary schools. The data were drawn from a short-term longitudinal study. RESULTS: Results showed, as hypothesized, that peer and friend relational victimization was conceptually and empirically different from peer and friend physical victimization. CONCLUSIONS: These findings suggest that children and teachers view peer and friend relational victimization and peer and friend physical victimization differently. Examining forms of victimization separately is promising for future peer relations research in Japan.

Ethnic Inequalities in Psychological Distress: A Population Data Linkage Study on the Pacific Island of Guåhån/Guam.

Psychological distress and mental illness has been found to be elevated in migrant groups living in sovereign countries, as well as for indigenous people living under colonial or administrative rule. The north Pacific island of Guam is unusual in its ethnic composition as it has no majority ethnic group, has a large indigenous population and remains a territory of the U.S. This study aimed to identify ethnic differences in self-reported psychological distress between the main ethnic groups on Guam. The study uses a cross sectional design with data linkage methodology, drawing on the Guam Census and the Behavioral Risk Factor Surveillance System health survey for Guam. The results showed that the native Chamorro population had worse self-reported psychological distress (defined as a 'mental health condition or emotional problem') than White/Caucasians (OR 2.09, 95% CI 1.52-2.87), particularly for severe distress (OR 3.61, 95% CI 1.33-2.77). This relationship persisted even after adjusting for a wide range of socio-demographic and economic factors (OR 2.58, 95% CI 1.15-5.76). Other Pacific Islanders also had higher psychological distress compared to White/Caucasians, but this association was largely explained by the adjusted factors. The findings are discussed in terms of social and economic disadvantage for Pacific Island peoples on Guam, as well as the impact of colonial administration, disaffection, and lack of autonomy for the Chamorro of Guam. Recommendations are made to improve psychiatric treatment for these groups by considering wider socio-political factors in assessment and treatment, as well as broader implications for the national dialogue on self-determination.

Relational-Interdependent Self-Construal and Gender Predicting Blood Pressure Reactivity and Recovery From Stress in Early Adolescence.

This study investigated the association between relational-interdependent self-construals (relational interdependence) and blood pressure reactivity and recovery from two types of peer stressors (i.e., relational and instrumental) and gender as a moderator of this association. One hundred and ninety-six early adolescents (M = 10.11 years) reported their relational interdependence and participated in a laboratory stress protocol in which their systolic and diastolic blood pressures before, during, and after experiencing peer stressors were assessed. Results indicated that for males only, those with high relational interdependence showed greater systolic blood pressure reactivity and, at a trend level, impaired recovery from instrumental stressors; females with high relational interdependence showed greater diastolic blood pressure reactivity to relational stressors.

Moderating Effects of Relational Interdependence on the Association Between Peer Victimization and Depressive Symptoms.

This short-term longitudinal study examined the association between relational and physical victimization and subsequent depressive symptoms together with the roles of social cognitive processes (i.e., relational interdependence) and gender in this association. A total of 580 Japanese adolescents in the seventh and eighth grades (52 % girls; age range 12-14) participated in this study across an academic year. Results of structural equation modeling demonstrated that relational and physical victimization, which was assessed via self- and teacher- reports, was concurrently associated with greater depressive symptoms, regardless of the gender of the youth and the level of relational interdependence. Furthermore, after controlling for the stability and co-occurrence between each construct, relational victimization (not physical victimization) was predictive of elevated depressive symptoms only for boys who exhibited relatively higher relational interdependence. The findings are discussed from developmental, gender, and cultural perspectives.

Direct and interactive links between cross-ethnic friendships and peer rejection, internalizing symptoms, and academic engagement among ethnically diverse children.

The present study examined direct and interactive links between friendships and social, academic, and psychological adjustment problems (i.e., peer rejection as nominated by same-ethnic and cross-ethnic peers, teacher-reported academic engagement, and teacher-reported internalizing symptoms) among school-age children in multiethnic schools (n = 509, age: 9-10). The data, which included 2 time points with a 6-month interval, were drawn from a relatively large-sized, short-term longitudinal study. Results showed that cross-ethnic friendships (not same-ethnic friendships) were associated with greater academic engagement concurrently and predated decreased peer rejection and internalizing symptoms longitudinally, even after controlling for the availability of same-ethnic peers and classroom diversity. Furthermore, cross-ethnic friendships (not same-ethnic friendships) moderated the link between relational victimization and increased peer rejection and greater internalizing symptoms, such that this link was evidenced for children with fewer cross-ethnic friendships. However, the moderation effect was contingent upon the type of outcome variables and the ethnicity of the child. For example, the buffering effect against the negative contribution of relational victimization to internalizing symptoms was found particularly for African American children. The findings are discussed based on theories of normative development, ethnic socialization, and intergroup relations.

Mechanisms and processes of relational and physical victimization, depressive symptoms, and children's relational-interdependent self-construals: implications for peer relationships and psychopathology.

This short-term longitudinal study examined the associations between relational and physical victimization and depressive symptoms, and the moderating role of school-aged children's relational-interdependent self-construals in these associations. The participants were 387 children (51.8% boys) who were in the fifth grade (M = 10.48 years, SD = 0.55) in Taiwan and followed at two time points (a 6-month interval) during a calendar year. A multiple-informant approach was used where forms of peer victimization, depressive symptoms, and relational-interdependent self-construals were assessed via peer nominations, teacher reports, and child reports, respectively. All measures had favorable psychometric properties. The results of a multigroup cross-lagged model demonstrated that relational victimization (not physical victimization) was positively predictive of subsequent depressive symptoms, and the effect was evidenced for highly interdependent children only. The opposite link was also significant, such that depressive symptoms predicted subsequent relational victimization (not physical victimization) for children who exhibited low and high levels of relational-interdependent self-construals. In contrast, physical victimization predated a lower level of depressive symptoms for highly interdependent children. These effects were unaffected by the gender of the child. The findings, especially the interactive effects of relational victimization (as a contextual factor) and relational-interdependent self-construals (as an individual vulnerability) on depressive symptoms, are discussed from a developmental psychopathology perspective.

Symptoms of attention-deficit/hyperactivity disorder and peer functioning: a transactional model of development.

The goals of this short-term longitudinal study were to investigate differential, independent effects of inattention and hyperactivity/impulsivity on children's peer relationships and the dynamic, transactional interplay between ADHD symptoms and indices of peer functioning over time. This study used a community sample that included 739 preadolescents (239 fourth graders and 500 fifth graders; 52.23 % boys) from northern Taiwan, who were assessed every six months at three time points. Children's ADHD symptoms were measured using the parent report on the Swanson, Nolan, and Pelham, version IV scale. Positive and negative facets of peer functioning, including peer rejection, peer acceptance, and the number of friendships, were assessed via peer nomination. Results of cross-lagged models indicated that inattention, but not hyperactivity/impulsivity, predicted subsequent peer impairment (i.e., lower peer acceptance and fewer dyadic friendships). Findings also showed a vicious cycle in which inattentive symptoms predicted later peer impairment, which in turn led to increases in both inattention and hyperactivity/impulsivity. These findings did not differ across gender, and the majority of the findings remained significant even after controlling for age and physical aggression. Taken together, this study demonstrated the detrimental effect of inattention on children's peer functioning and the transactional and dynamic interplay between inattention and peer impairment in a Chinese culture.

The Role of Preschool Relational and Physical Aggression in the Transition to Kindergarten: Links with Social-Psychological Adjustment.

RESEARCH FINDINGS: The transition to kindergarten has important ramifications for future achievement and psychosocial outcomes. Research suggests that physical aggression may be related to difficulty during school transitions, yet no studies to date have examined the role of relational aggression in these transitions. This paper examined how engagement in preschool physical and relational aggression predicted psychosocial adjustment during the kindergarten school year. Observations and teacher reports of aggression were collected in preschool, and kindergarten teachers reported on student-teacher relationship quality, child internalizing problems, and peer acceptance in kindergarten. Results suggested that preschool physical aggression predicted reduced peer acceptance and increased conflict with the kindergarten teacher. High levels of relational aggression, when not combined with physical aggression, were related to more positive transitions to kindergarten in the domains assessed. PRACTICE OR POLICY: These data lend support to the need for interventions among physically aggressive preschoolers to target not only concurrent behavior but also future aggression and adjustment in kindergarten. Thus, educators should work to encourage social influence in more prosocial ways amongst aggressive preschoolers.

Adaptive, maladaptive, mediational, and bidirectional processes of relational and physical aggression, relational and physical victimization, and peer liking.

A three-wave longitudinal study among ethnically diverse preadolescents (N = 597 at Time 1, ages 9-11) was conducted to examine adaptive, maladaptive, mediational, and bidirectional processes of relational and physical aggression, victimization, and peer liking indexed by peer acceptance and friendships. A series of nested structural equation models tested the hypothesized links among these peer-domain factors. It was hypothesized that (1) relational aggression trails both adaptive and maladaptive processes, linking to more peer victimization and more peer liking, whereas physical aggression is maladaptive, resulting in more peer victimization and less peer liking; (2) physical and relational victimization is maladaptive, relating to more aggression and less peer liking; (3) peer liking may be the social context that promotes relational aggression (not physical aggression), whereas peer liking may protect against peer victimization, regardless of its type; and (4) peer liking mediates the link between forms of aggression and forms of peer victimization. Results showed that higher levels of peer liking predicted relative increases in relational aggression (not physical aggression), which in turn led to more peer liking. On the other hand, more peer liking was predictive of relative decreases in relational aggression and relational victimization in transition to the next grade (i.e., fifth grade). In addition, relational victimization predicted relative increases in relational aggression and relative decreases in peer liking. Similarly, physical aggression was consistently and concurrently associated more physical victimization and was marginally predictive of relative increases in physical victimization in transition to the next grade. More peer liking predicted relative decreases in physical victimization, which resulted in lower levels of peer liking. The directionality and magnitude of these paths did not differ between boys and girls.

A cross-lagged structural equation model of relational aggression, physical aggression, and peer status in a Chinese culture.

This short-term longitudinal study examined the associations among relational aggression, physical aggression, and peer status (i.e., acceptance, rejection, and perceived popularity) across three time points, six months apart, in a Taiwanese sample. Participants were 198 fifth grade students (94 girls and 104 boys; Mean age = 10.35 years) from Taipei, Taiwan. Study variables were assessed using peer nomination procedure. Results from the cross-lagged structural equation models demonstrated that there were longitudinal associations between relational aggression and each of the peer status constructs while only one longitudinal association was found for physical aggression such that physical aggression positively predicted subsequent peer rejection. The longitudinal associations did not vary with gender. Results also showed high stabilities of relational aggression, physical aggression, and the three peer status constructs over 1 year as well as high concurrent association between relational and physical aggression. In addition, relational aggression and physical aggression were concurrently related to less acceptance, more rejection, and less perceived popularity, especially at the outset of the study. Findings of this study demonstrated both similarities and differences in relation to previous literature in primarily Western cultures. This study also highlights the bidirectional and complex nature of the association between aggression and peer status, which appears to depend on the form of aggression and on the particular indicator of peer status under study.

Developmental trajectories of chinese children's relational and physical aggression: associations with social-psychological adjustment problems.

The purpose of this short-term longitudinal study was to examine Chinese children's trajectories of physical and relational aggression and their association with social-psychological adjustment problems (i.e., depressive symptoms and delinquency) and gender. Fourth and fifth grade children in Taiwan (n = 739, age 9-11) were followed across 1 year. Results of Linear Mixed Models demonstrated that, on average, relational aggression increased in a linear fashion for fifth grade children and girls and physical aggression remained stable for boys and increased linearly for fifth grade girls. Further, increases in relational aggression were associated with time-dependent increases in depressive symptoms, and the effect size of this association seemed to be stronger than that of physical aggression. Findings are discussed in the context of Chinese culture.
