Standard Deviation vs. Gini Coefficient: Effects of Different Indicators of Classroom Status Hierarchy on Bullying Behavior.

Classroom status hierarchy (the degree to which popularity is unequally distributed in a classroom) has often been examined as a predictor of bullying. Although most research has relied on an operationalization of status hierarchy as the classroom standard deviation (SD) of popularity, other fields (e.g., sociology, economics) have typically measured resource inequality using the Gini coefficient. This multilevel study examines the concurrent and prospective associations of both status hierarchy indicators (referred to as SD-hierarchy and Gini-hierarchy) with peer-reported bullying, controlling for key variables (i.e., the structure of the classroom status hierarchy, average classroom level of popularity). The final sample included 3017 students (45.3% self-identified as a boy; T1 Mage = 13.04, SD = 1.73, approximately 93% born in Finland) from 209 classrooms. Concurrently, classroom SD-hierarchy was positively, linearly associated with bullying, whereas there was a curvilinear (inverted U) association between Gini-hierarchy and bullying. No significant longitudinal associations were found. The findings suggest that Gini-hierarchy provides unique information beyond the SD-hierarchy.

The longitudinal role of classroom defending norms in victims' psychological adjustment, causal attributions, and social comparisons.

Frequent exposure to victimization by peers is related to greater psychological problems. It is often assumed that peer victimization is associated with fewer psychological problems in classrooms where defending victims of bullying is common (i.e., a norm). The few studies testing this claim have been cross-sectional and have produced mixed findings. The current preregistered study examined whether the prospective link between victimization and psychological adjustment (i.e., depressive symptoms and self-esteem) was moderated by classroom defending norms. Moreover, we aimed to explain why defending norms may have either beneficial or adverse effects on victims' adjustment, by focusing on two cognitive processes: victims' causal attributions and social comparisons. Three waves of data were collected among 3,470 Finnish fourth- to ninth-grade students from 227 classrooms (Mage = 13.04, 50.1% girls). Multilevel regression analyses showed that nonvictimized youth benefited from high defending norms, whereas victims' psychological adjustment did not vary as a function of defending norms. Therefore, no mediation analyses were conducted. Nonpreregistered additional analyses indicated that stable victims had greater psychological problems and higher self-blame over time in classrooms with higher defending norms. Thus, even though the majority of students seem to profit from defending norms, this might not be true for those who most urgently need help.

Is there really a healthy context paradox for victims of bullying? A longitudinal test of bidirectional within-and between-person associations between victimization and psychological problems.

The finding that victims' psychological problems tend to be exacerbated in lower-victimization classrooms has been referred to as the "healthy context paradox." The current study has put the healthy context paradox to a strict test by examining whether classroom-level victimization moderates bidirectional within- and between-person associations between victimization and psychological adjustment. Across one school year, 3,470 Finnish 4th to 9th graders (Mage = 13.16, 46.1% boys) reported their victimization, depressive symptoms, anxiety, and self-esteem. Three types of multilevel models (cross-lagged panel, latent change score, and random-intercept cross-lagged panel) were estimated for each indicator of psychological adjustment. Findings indicated that the healthy context paradox emerges because classroom-level victimization moderates the prospective effect of victimization on psychological problems, rather than the effect of psychological problems on victimization. In classrooms with lower victimization, victims not only experience worse psychological maladjustment over time compared to others (between-person changes), but also higher maladjustment than before (absolute within-person changes).

Adolescent victimization predicts adult depression and aggression: The role of rumination.

Victimization during school years can have detrimental effects on individuals' adjustment, lasting even into adulthood. In the current study, we examine whether there is an indirect effect of victimization on adult depression and aggression, via sad and angry rumination about past victimization. Participants included 1,319 Finnish individuals (59.5% identified as women; 97.4 native Finns) who were followed from adolescence into adulthood (Mage = 25.78, SD = 1.35). Victimization was indirectly associated with adult depression and aggression, through sad and angry ruminations, respectively. The findings suggest that intervention efforts targeting rumination could help victimized individuals avoid lasting ill effects from their experiences.

Does defending affect adolescents' peer status, or vice versa? Testing the moderating effects of empathy, gender, and anti-bullying norms.

This study examined bidirectional associations between students' bully-directed defending behavior and their peer status (being liked or popular) and tested for the moderating role of empathy, gender, and classroom anti-bullying norms. Three waves of data were collected at 4-5-month time intervals among 3680 Finnish adolescents (Mage = 13.94, 53.0% girls). Cross-lagged panel analyses showed that defending positively predicted popularity and, to a larger degree, being liked over time. No moderating effect of empathy was found. Popularity was more strongly predictive of defending, and defending was more strongly predictive of status among girls than among boys. Moreover, the positive effects of both types of status on defending were-albeit to a limited extent-stronger in classrooms with higher anti-bullying norms.

Peer victimization and empathy for victims of bullying: A test of bidirectional associations in childhood and adolescence.

Anti-bullying interventions often assume that knowing how it feels to be bullied increases empathy for victims. However, longitudinal research on actual experiences of bullying and empathy is lacking. This study investigated whether within-person changes in victimization predicted changes in empathy over 1 year using random-intercept cross-lagged panel models. Self- and peer-reported victimization, and cognitive and affective empathy for victims were measured in a sample of 15,713 Finnish youth (Mage  = 13.23, SDage  = 2.01, 51.6% female; 92.5% had Finnish-speaking parents; data was collected in 2007-2009 when information about participants' race/ethnicity was not available due to ethical guidelines for the protection of personal information). Results indicated small, positive longitudinal associations from victimization to cognitive empathy. Implications for empathy-raising interventions are discussed.

Does defending victimized peers put youth at risk of being victimized?

Defending peers who have been bullied is often thought to put defenders at risk of becoming victimized themselves. The study investigated the concurrent and prospective associations between defending and (peer- and self-reported) victimization, and examined popularity and classroom norms as potential moderators. Participants included 4085 Finnish youth (43.9% boys; Mage  = 14.56, SD = .75; 97% born in Finland). Concurrently, defending was positively associated with self-reported victimization in classrooms with high bullying-popularity norms (b = .28, SE = .16). Defending was negatively associated with peer-reported victimization in classrooms with high defending-popularity norms (b = -.07, SE = .03). Defending was not significantly associated with future victimization, suggesting that it is generally not a risk factor for victimization.

Social Adjustment of Problem-Talk Partners Moderates Associations Between Self-Perceived Victimization and Depressive Symptoms.

This paper examines the moderating role of problem-talk partnerships with peers who are rejected, victimized, or unpopular on links between self-perceived victimization by peers and depressive symptoms. Problem-talk partnerships are friendships that involve frequent discussion of problems and personal struggles. 267 adolescents (152 girls; mean age of 14.4 years) participated in a short-term prospective study with identical measures administered in two annual waves. The adolescents completed a battery of self-report questionnaires assessing peer victimization and depression. They also completed a peer nomination inventory and identified friends with whom they frequently discuss problems. High levels of peer nominated victimization, social rejection, and unpopularity among problem-talk partners were linked to elevated associations between self-reported victimization and depressive symptoms. The effects for unpopularity levels among problem-talk partners were moderated by gender. Compared to boys, girls' adjustment was more strongly influenced by unpopularity among problem-talk partners. Conversely, friendships with peers who were not problem-talk partners did not have a consistent moderating role. The full pattern of findings highlights the need to consider the social adjustment of dyadic partners when examining the psychosocial impact of perceived victimization.

Differences in Aggression and Alcohol Use among Youth with Varying Levels of Victimization and Popularity Status.

Awareness that high-status adolescents can be targets of aggression has grown in recent years. However, questions remain about the associations of the confluence of victimization and popularity with adjustment. The current study fills this gap by examining the joint and unique effects of victimization and popularity on aggression and alcohol use. Participants were 804 Dutch adolescents (50.2% boys, Mage = 13.65) who were followed for one year. High-status victims were more aggressive and drank more alcohol than lower-status victims. High-status victims were also more proactively and indirectly aggressive and self-reported more bullying than high-status non-victims. Thus, the findings demonstrated a conjoined risk of victimization and popularity for some types of aggression.

Is aggression associated with biased perceptions of one's acceptance and rejection in adolescence?

In adolescence, being rejected by one's peers is positively associated with aggression. However, whether self-perceptions of being rejected or accepted by peers, and biases in these perceptions, are linked to aggression remains unclear, as the literature points to 2 perspectives: Youth are more likely to be aggressive when they (a) know or believe that they are rejected or (b) overestimate their acceptance. By addressing some of the limitations of prior studies, this study aimed to clarify how self-perceptions of status are related to concurrent and future aggression, and whether high levels of aggression are predictive of biased self-perceptions of acceptance and rejection. Data were collected in 2 consecutive school years from 572 high school students (Mage = 15.06, SD = .75; 55.4% girls). The ethnic/racial composition of the sample was 47.5% Asian, 43.1% Latino/Hispanic, 4.0% White, and 5.3% other. For well-liked youth, awareness of one's acceptance was positively associated with concurrent relational aggression, whereas for highly rejected youth, awareness of one's rejection was positively associated with concurrent overt aggression. Awareness of being rejected (i.e., high levels of both self-perceived and actual rejection) was associated with elevated levels of aggression over time. There was no evidence that youth with high levels of aggression had more biased perceptions of their status (concurrently or longitudinally) than youth with low levels of aggression. These findings help clarify how youth's status-related perceptions relate to the development of aggression. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Bullying Prevention in Adolescence: Solutions and New Challenges from the Past Decade.

Bullying among youth at school continues to be a global challenge. Being exposed to bullying may be especially hurtful in adolescence, a vulnerable period during which both peer group belonging and status become key concerns. In the current review, we first summarize the effectiveness of the solutions that were offered a decade ago in the form of anti-bullying programs. We proceed by highlighting some intriguing challenges concomitant to, or emerging from these solutions, focusing especially on their relevance during adolescence. These challenges are related to (1) the relatively weak, and highly variable effects of anti-bullying programs, (2) the complex associations among bullying, victimization, and social status, (3) the questions raised regarding the beneficial (or possibly iatrogenic) effects of peer defending, and (4) the healthy context paradox, that is, the phenomenon of remaining or emerging victims being worse off in contexts where the average levels of victimization decrease. We end by providing some suggestions for the next decade of research in the area of bullying prevention among adolescents.

Adolescent Victim Types Across the Popularity Status Hierarchy: Differences in Internalizing Symptoms.

Previous studies have called attention to the fact that popular youth are not immune to peer victimization, suggesting there is heterogeneity in the popularity of victims. Yet, no study to date has determined whether victims with different levels of popularity status can be identified using person-oriented analysis. Such analysis is critically needed to confirm the existence of popular victims. Further, there remains a paucity of research on internalizing indices of such popular victims, especially compared to other victim and non-victim groups. To address this gap in the research literature, the current study used latent profile analysis to identify subgroups of victims based on victimization (self- and peer-report) and popularity (peer-report). This study sought to verify the existence of popular victims and to compare victim subgroups on loneliness and self-esteem. Participants were 804 Dutch adolescents (50.2% boys, Mage = 13.65 years, ranging from 11.29 to 16.75 years). The results revealed six subgroups, including a group of popular self-identified victims. Popular self-identified victims were generally less lonely than other victims, but had higher loneliness and lower self-esteem than non-victims. Implications are discussed for understanding the victimization experiences of high-status youth.

Examining the Potential Mental Health Costs of Defending Victims of Bullying: a Longitudinal Analysis.

It has been speculated that defending victims of bullying is stressful for youth, and may contribute to poor mental health among those who regularly intervene to defend their victimized peers. However, the extant literature is thus far primarily limited to correlational, single-informant studies. The current study examined the concurrent and prospective mental health costs (e.g., social anxiety, depressive symptoms) of peer-reported defending among 4085 youth (43.9% boys; Mage = 14.56, SD = 0.75). Moreover, we examined two potential moderators (victimization and popularity) of the association between defending and internalizing problems. Analyses revealed that there was no evidence of a direct, positive relationship between defending and internalizing symptoms. However, a positive, concurrent association was found between defending and social anxiety, but only among youth who reported that they were also victims - the association was negative among non-victimized youth. In addition, both peer-reported victimization and social status were found to moderate the longitudinal relationship between defending and later symptoms of depression. Specifically, among low-status highly victimized youth, defending was associated with an increased risk of experiencing symptoms of depression, whereas high-status youth who were rarely seen as victims reported decreased symptoms of depression at T2 if they also had a reputation for defending others. The findings suggest that defending others is likely not a risk factor for youth who are not already vulnerable and/or have the protection of high status, and may actually have a protective effect for these youth.

Rumination as a Mediator of the Prospective Association Between Victimization and Bullying.

Although there is evidence of concurrent associations between victimization and bully perpetration, it is still unclear how this relation unfolds over time. This study investigates whether victimization in childhood is a prospective risk factor for bully perpetration in early adolescence, and examines rumination as a socio-cognitive factor that may mediate this association. Participants included 553 third graders (43.2% boys; Mage = 9.85), with follow-up assessments when they were in fourth, seventh, and eighth grade. Results indicated that more frequent victimization in grades 3 and 4 was indirectly associated with bully perpetration in grade 8, through rumination in grade 7 about past victimization experiences in elementary school. This pattern remained regardless of whether the rumination elicited feelings of anger or sadness. Our findings demonstrate one pathway through which frequent victimization can lead to perpetration and underscore the important role of rumination in victims' subsequent adjustment. Implications for future interventions are discussed.

Bidirectional Associations between Popularity, Popularity Goal, and Aggression, Alcohol Use and Prosocial Behaviors in Adolescence: A 3-Year Prospective Longitudinal Study.

Adolescents' popularity and popularity goal have been shown to be related to their aggression and alcohol use. As intervention efforts increasingly aim to focus on prosocial alternatives for youth to gain status, it is essential to have a comprehensive understanding of how popularity and popularity goal are associated with aggression and substance use as well as prosocial behaviors over time. The current study examined the bidirectional associations of aggression (overt and relational aggression), alcohol use, and prosocial behavior with popularity and popularity goal in adolescence across 3 years using cross-lagged panel analyses. Participants were 839 Dutch adolescents (Mage = 13.36, SD = 0.98; 51.3% girls). The results indicated that popularity was consistently positively associated with popularity goal, but popularity goal did not significantly predict subsequent popularity. Popularity positively predicted elevated aggression and alcohol use, but lower levels of prosocial behavior. For the full sample, alcohol use and overt aggression in grade 7 both predicted subsequent popularity in grade 8. However, when considering gender differences, overt aggression no longer was a significant predictor of popularity. These results were discussed in terms of the dynamic interplay between popularity, popularity goal, and behaviors, and in terms of implications for prevention and intervention efforts.

Prospective Associations between Popularity, Victimization, and Aggression in Early Adolescence.

Recent research has highlighted an understudied phenomenon in the peer victimization literature thus far: the overlap between high status (i.e., popularity) and victimization. However, the research on this phenomenon has primarily been cross-sectional. The current investigation uses a longitudinal design to address two questions related to high-status victims. First, the present study examined prospective associations between popularity and two forms of indirect victimization (reputational victimization and exclusion). Second, this study examined elevated aggression as a consequence of high-status youth's victimization (using self- and peer- reports of victimization). Participants were 370 adolescents (Mage = 14.44, range = 14.00-16.00; 56.5% girls) who were followed for 1 year. Both high and low levels of popularity were prospectively associated with reputational victimization. Moreover, popularity moderated the association between self-reported indirect victimization (but not peer-reported indirect victimization) and aggression. The results help build toward a more comprehensive understanding of both victimization and aggression in adolescence. Findings are discussed in terms of implications for a cycle of aggression in youth and the lowered effectiveness of bullying interventions in adolescence.

Dyadic nominations of bullying: Comparing types of bullies and their victims.

Previous studies indicate that when identifying individuals involved in bullying, the concordance between self- and peer- reports is low to moderate. There is support that self- and peer- identified victims constitute distinct types of victims and differ in adjustment. Likewise, differentiating between self- and peer- reports of bullying may also reveal distinct types of bullies. The goal of this study was to examine differences between types of bullies identified via dyadic nominations (self-identified, victim-identified, and self/victim identified). First, we examined the concordance between dyadic nominations of bullying and traditional measures of bullying (i.e., self- and peer-reports). Second, we compared the behavioral profiles of the bully types to nonbullies, with a focus on aggressive behaviors and social status. Third, we examined whether the types of bullies targeted victims with different levels of popularity, as well as the role of their own popularity and prioritizing of popularity. Participants were 1,008 Dutch adolescents (50.1% male, Mage = 14.14 years, standard deviation [SD] = 1.30) who completed a classroom assessment of dyadic nominations, peer nominations, and self-report items. Results indicated that victim identified and self/victim identified bullies were more aggressive, more popular, and less socially preferred than self-identified bullies and nonbullies. Self/victim identified bullies targeted victims with the highest social status. The association between bully type and victims' popularity was further qualified by bullies' own popularity and the degree to which they prioritized popularity. Implications for the implementation of dyadic nominations are discussed.
