Addressing Measurement Issues Related to Bullying Involvement

Developmental Relations Between Peer Victimization, Emotional Symptoms, and Disability/Chronic Condition in Adolescence: Are Within- or Between-Person Factors Driving Development?

Although there is a link between peer victimization, emotional symptoms, and disability or chronic condition in adolescence, less is known about the role of stable, individual differences compared to developmental processes. The current study addressed this gap by examining developmental relations between peer victimization, emotional symptoms, and disability or chronic condition. Three waves of self-report panel data on Swedish adolescents at ages 13, 15, and 17 years (n = 734; 51.6% girls) were used. Data were analyzed using random-intercept cross-lagged panel models with invariance tests by sex, disability/chronic condition, and family affluence. Girls and adolescents with a disability or chronic condition showed more heterogeneity in the co-development of peer victimization and emotional symptoms, with girls being more prone than boys to developing emotional symptoms following peer victimization, and particularly in early adolescence. Girls and adolescents with a disability or chronic condition had elevated within-person levels of both peer victimization and emotional symptoms throughout adolescence. Theory and practice may need to pay additional attention to the role of sex, disability, and their intersection, as well as age, regarding the development of peer victimization and emotional symptoms.

Admitting to bullying others or denying it: Differences in children's psychosocial adjustment and implications for intervention

This study examined whether, for bullying perpetrators, admitting to their behavior was associated with specific psychosocial characteristics, and whether it predicted decreases in bullying behavior and a higher responsiveness to a successful anti-bullying program after 9 months of implementation. It also investigated whether participation in an anti-bullying program deterred admitting to the behavior. At pretest, our sample included 5,908 children and early adolescents (M age: 11.2 years) in 39 intervention and 38 control schools; among them, 1,304 were peer-identified bullying perpetrators (scoring higher or equal to 0.5 SD above the same-sex classroom mean). Regression analyses indicated that peer-identified bullying perpetrators who admitted to their behavior were more likely to suffer from internalizing problems and reported lower anti-bullying attitudes than those who did not admit to bullying others. There was no significant main effect of admitting to bullying on changes in peer-reported bullying 1 year later. However, in control schools only, those who admitted to bullying at pretest were more likely to continue bullying a year later than those who denied it. There was no evidence that participating in the anti-bullying program made it less likely for peer-identified bullying perpetrators to admit to their behavior.

Literature Review and Content Analysis of Bullying Assessments: Are We Measuring What We Intend to?

The initial phase in any initiative aimed at preventing bullying involves evaluating the present prevalence to pinpoint students who might be more susceptible to involvement in the bullying dynamic. Assessment serves as a guide for shaping future decisions regarding intervention. The purpose of this study was to identify and evaluate current assessment tools to determine the extent to which the bullying dynamic is currently measured. The results indicated that assessment tools measured verbal bullying/victimization most frequently, followed by relational and physical. Also, items measured repetition and intent about 50% of the time, while they measured power imbalance less frequently (i.e., 25%). The importance of matching an appropriate assessment to a school's needs is emphasized. Implications for both researchers and practitioners are discussed.

Reactivity to Peer Rejection Moderates the Effect of Victimization on Adolescent Girls' Depressive Symptoms: A Prospective Study

Peer victimization and bullying behaviors are prevalent during adolescence and have been linked to depression. This study examined whether peer rejection reactivity, defined as physiological responses to peer exclusion, moderated the associations of victimization and bullying behaviors with depressive symptoms 12 months later in a sample of female youths (N = 79, Mage = 13.37 ± 2.31). Participants underwent the Yale Interpersonal Stressor-Child, during which systolic and diastolic blood pressure and heart rate were continuously measured. Parent and youth reports of the youth's depressive symptoms were utilized. Our results demonstrate that peer rejection reactivity moderates the relationship between victimization and subsequent depressive symptoms but does not moderate the relationship between bullying behaviors and subsequent depressive symptoms. Higher victimization was associated with increased youth-reported depressive symptoms among girls with high reactivity but decreased depressive symptoms among girls with low reactivity. Future research can explore whether reducing emotional and physiological reactivity to peer rejection, as well as increasing interpersonal effectiveness in peer relationships, can reduce depressive symptoms in adolescent girls experiencing victimization.

Self-ratings and peer-ratings of bullying perpetrators: Intrapersonal and interpersonal factors that differentiate bully subgroups

Using a large sample of students (N = 1373; 40% girls; Mage = 14 years) from 54 classrooms in South Korea, this study identified subtypes of bullies based on specific combinations of self-reports and peer-reports and examined the intrapersonal and interpersonal factors that explain the differences in characteristics between these identified groups. Latent profile analysis identified four subgroups of bullies: (a) non-bullies (59.5%), (b) peer-identified bullies (21%), (c) self-identified bullies (9.8%), and (d) self/peer-identified bullies (9.7%). Multinomial logistic hierarchical analysis revealed significant differences between the bully subgroups on the four intrapersonal factors (i.e., anti-bullying attitudes, perception of teachers' reaction to bullying, delinquent behavior, and depression; odds ratios [OR] ranged from 0.24 to 3.13) and three of the four interpersonal factors (i.e., overestimated popularity, rejection, and victimization; ORs ranged from 0.39 to 2.26). More specifically, compared to the peer-identified bully group, the non-bully and self/peer-identified bully groups showed opposite patterns of anti-bullying attitudes, delinquent behavior, and peer status (ORs ranged from 0.46 to 3.13). Relative to the peer-identified bully group, the self-identified bully group was more likely to exhibit depressive symptoms and perceive themselves as being victimized, was less likely to endorse anti-bullying attitudes, and had a less positive perception of teacher's reaction to bullying (ORs ranged from 0.24 to 1.40). Gender differences emerged as well. Implications for optimizing the screening of bullying perpetrators and anti-bullying interventions are discussed.

Longitudinal study of peer victimization, social support, and mental health during early adolescence

BACKGROUND

Peer victimization predicts the development of mental health symptoms in the transition to adolescence, but it is unclear whether and how parents and school environments can buffer this link.

METHODS

We analyzed two-year longitudinal data from the Adolescent Brain Cognitive Development (ABCD) study, involving a diverse sample of 11 844 children across the United States (average at baseline = 9.91 years; standard deviation = 0.63; range = 8.92-11.08; complete case sample = 8385). Longitudinal associations between peer victimization and two-year changes in mental health symptoms of major depression disorder (MDD), separation anxiety (SA), prodromal psychosis (PP), and attention-deficit/hyperactivity disorder (ADHD) were examined including a wide range of covariates. Mixed linear models were used to test for the moderating effects of parental warmth and prosocial school environment.

RESULTS

20% of children experienced peer victimization. Higher exposure to peer victimization was associated with increases in MDD, SA, and ADHD symptoms. Parental warmth was associated with decreases in MDD symptoms but did not robustly buffer the link between peer victimization and mental health symptoms. Prosocial school environment predicted decreases in PP symptoms and buffered the link between peer victimization and MDD symptoms but amplified the link between peer victimization and SA and ADHD symptoms.

CONCLUSIONS

Peer victimization is associated with increases in mental health symptoms during the transition to adolescence. Parental warmth and prosocial school environments might not be enough to counter the negative consequences of peer victimization on all mental health outcomes.

Suicidality Among Syrian Refugee Children in Jordan

History of adverse events in childhood is one of the strongest predictors of developing negative mental health outcomes with suicidality being the most devastating consequence. Syrian refugee children are at very high risk of developing mental illness, however, the prevalence and significance of suicidal thoughts among this population remains undocumented. A total of 339 Syrian refugee children and adolescents aged 10 to 17 years and their parents living in Jordan were surveyed to assess resilience, depression and suicidality. Demographics and parental depression were correlated with child suicidality. Multivariate logistic regression analyses were used to determine the predictors of suicidality within this population. A total of 94 (27.7%) children reported suicidal statements. In the multivariate analyses we found that younger children were more likely to state suicidal ideation than older children. Of the children who stated suicidal ideation, 49 were in primary school, 19 in pre-secondary and 26 in upper-secondary school. In the multivariate analyses, mild (OR 2.633 (95% CI 1.283, 5.709)) and high (OR 6.987 (95% CI 3.532, 14.614)) depression levels among the surveyed children were predictive of suicidality. Experiencing bullying was also predictive of suicidality (OR 2.181 (95% CI 1.179, 4.035)) when compared to those who did not report any bullying. We report high rates of suicidal ideation among Syrian refugee children, especially in children with exposure to pre-existing depression or bullying. Prevention through raising awareness, education and early detection of depression are needed to address suicidality in this and other vulnerable populations of children.

Long-term consequences of bullying involvement in first grade

Few prospective studies have examined how early bullying experiences impact long-term adjustment and the differential impact of children's co-occurring bullying and peer victimization involvement on adjustment in adulthood. This study addressed these gaps by examining subgroups of first graders involved in bullying and associations with four outcomes in early adulthood, including (a) Major Depression diagnosis, (b) post-high school suicide attempt, (c) on-time high school graduation, and (d) criminal justice involvement. Additionally, middle school standardized reading test scores and suspensions were examined as potential mechanisms through which early bullying involvement is associated with adult outcomes. Participants were 594 children from nine urban elementary schools in the United States who participated in a randomized controlled trial of two school-based universal prevention interventions. Latent profile analyses using peer nominations identified three subgroups: (a) High involvement bully-victims, (b) Moderate involvement bully-victims, and (c) Low/No involvement youth. Compared to the No/Low involvement class, High involvement bully-victims were less likely to graduate high school on time (OR = 0.48, p = .002) and Moderate involvement bully-victims were more likely to be involved in the criminal justice system (OR = 1.37, p = .02). High bully-victims were at greater risk for both not graduating high school on-time and criminal justice system involvement, which were partially explained by 6th grade standardized reading test scores and suspensions. Moderate bully-victims were less likely to graduate high school on time, which was partially explained by 6th grade suspensions. Findings highlight how early bully-victim involvement increases risk for difficulties that affect adult quality of life.

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.

Bullying perpetration and social status in the peer group: A meta-analysis

INTRODUCTION

Associations between bullying perpetration and social status vary, not only between different facets of social status but also between bullying in primary versus secondary school. The main aim of the present study was to meta-analyse existing evidence regarding the prospective associations between bullying perpetration and various facets of social status, that is, popularity, peer acceptance, peer rejection, and social preference.

METHODS

Electronic databases were searched to identify studies on bullying perpetration and later social status published up to January 17, 2022. Multilevel random effects models were performed using Metafor and differences in effect sizes as a function of substantive and methodological moderators were tested.

RESULTS

In total, 116 effects were included from 18 publications, reporting on 17 different samples and more than 15,000 participants (mean age bullying assessment = 11.57 years, on average 51% female participants). Most samples were from the United States (7) or Europe (7). Overall, bullies were more popular, but also more rejected and scored lower on social preference compared with non-bullies. These associations remained when effects were adjusted for previous social status and other confounders. No link between bullying perpetration and acceptance was found. There was little evidence that effect sizes differed as a function of moderators.

CONCLUSIONS

Bullies become more popular over time, but also have a higher risk of being rejected and being less socially preferred. Bullying perpetrators are more popular but also more rejected by their peers. There is no evidence that these links differ depending on sex or age at which perpetrators bully, reporter or type of bullying.

Does Bullying Occur behind Closed Doors? Agreement of Bullying Reports between Parents and Children and Its Differential Associations with Child Outcomes

The present study was aimed at examining the level of agreement between parent and child perceptions of sibling and peer bullying (victimization and perpetration), and investigating whether any differential associations with child emotional and conduct problems could be identified across raters. The actor-partner interdependence model (APIM) was utilized in order to statistically account for the non-independence of the parent-child dyad. The study was based on a sample of 142 parent-child dyads (children: M_age = 12.3 years; parents: M_age = 44.4 years) and employed an online survey design. Bullying experiences and child outcomes were assessed via parent- and self-report. Intraclass correlation analysis revealed a moderate level of agreement between parent- and child-reports of sibling and peer bullying victimization. Low to moderate levels of parent-child agreement emerged for sibling perpetration and low agreement for peer perpetration. Moreover, APIMs found that parent- and child-reports of bullying were differentially associated with child adjustment. The results of this study suggest that child- and parent data each add additional and unique information into the big picture. Thus, our findings argue for the utility of integrating parent and child perspectives simultaneously in research and clinical practice, in order to uncover the complex reality of child functioning in the context of the family system.

Latent classes of aggression and peer victimization: Measurement invariance and differential item functioning across sex, race-ethnicity, cohort, and study site

Peer victimization is common and linked to maladjustment. Prior research has typically identified four peer victimization subgroups: aggressors, victims, aggressive‐victims, and uninvolved. However, findings related to sex and racial‐ethnic differences in subgroup membership have been mixed. Using data collected in September of 2002 and 2003, this study conducted confirmatory latent class analysis of a racially‐ethnically diverse sample of 5415 sixth graders (49% boys; 50.6% Black; 20.9% Hispanic) representing two cohorts from 37 schools in four U.S. communities to replicate the four subgroups and evaluate measurement invariance of latent class indicators across cohort, sex, race‐ethnicity, and study site. Results replicated the four‐class solution and illustrated that sociodemographic differences in subgroup membership were less evident after accounting for differential item functioning.

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 (M_age = 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, M_age  = 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.

The Role of Metacognitions and Thinking Styles in the Negative Outcomes of Adolescents' Peer Victimization

Psychological mechanisms that may explain the link between peer victimization and its adverse outcomes are still understudied. The current study aimed to apply the Self-Regulatory Executive Function (S-REF) model of psychopathology (Wells & Matthews, 1994, 1996) to help explain this link in a sample of adolescents. A total of 1,169 Italian adolescents (47.7% females; M_age = 15.79, SD = 1.07) completed self-report measures of peer victimization, metacognitions, thinking styles (worry and rumination), and adjustment indices (somatic symptoms, anxiety, depression). The hypothesized model based on the S-REF model was tested through path analysis. Results confirmed that peer victimization was positively associated with both positive and negative metacognitions that, in turn, were linked to worry and rumination, which were associated with higher psychological and somatic problems. The strongest indirect links were found between peer victimization and anxiety via negative metacognitions and worry, and between victimization and depression via negative metacognitions and rumination. Overall, the results support to the application of the S-REF model to peer victimization experiences during adolescence. The clinical implications of these findings are discussed.

Preadolescent children's perception of power imbalance in bullying: A thematic analysis

Bullying in schools is associated with an extensive public health burden. Bullying is intentional and goal oriented aggressive behavior in which the perpetrator exploits an imbalance of power to repeatedly dominate the victim. To differentiate bullying from aggressive behavior, assessment must include a valid measure of power imbalance as perceived by the victim. And yet, to date, there remains no agreement as to how to most accurately measure power imbalance among preadolescent children. This qualitative study explored children’s (age 9 to 11) understanding of power imbalance through thematic analysis of focus group discussions. Subthemes that emerged as influencing power imbalance include: age of victim, peer valued characteristics, and group membership and position. Subthemes of empathy and peer valued characteristics emerged as protecting against the negative impact of power imbalance.

Item Generation and Content Validity of the Child-Adolescent Bullying Scale

BACKGROUND

Healthcare providers do not uniformly screen young patients for exposure to bullying, and no screening instruments have been developed for widespread use in clinical settings.

OBJECTIVES

The objectives of this study were to (a) generate scale items by identifying and eliciting concepts relevant to youths with potential exposure to bullying as well as to professionals who work with bullied youths and (b) assess the content validity of the new Child-Adolescent Bullying Scale (CABS) instrument.

METHODS

A mixed-methods design was used to develop an initial pool of 52 items. The study was conducted in four phases: (I) comprehensive review of the existing literature; (II) concept elicitation through the conduct of focus groups with school-age youths and professionals who work with bullied youths; (III) concept selection and item construction; and (IV) content validation assessment of relevance, clarity, and dimension of each item by a panel of 30 international bullying and measurement experts through completion of an online survey.

RESULTS

An initial pool of 52 potential items was developed during Phases I-III of the study. During Phase IV, item- and scale-level content validity indices were calculated and were used to refine the item pool. These strategies resulted in a new, 22-item tool, with scale-level content validity indices of .954 for clarity and .920 for representativeness.

DISCUSSION

Evaluation of the CABS tool with a sample of youths drawn from healthcare settings will be necessary to assess the performance of the CABS items, further evaluate its psychometric properties, and further refine the tool.

Relations between Parent Psychological Control and Parent and Adolescent Social Aggression

Parent-child interactions and parenting behavior may be related to social aggression among adolescents, and adolescents' social aggression may relate to parents' social aggression. This study investigated (a) whether parent psychological control predicted future adolescent and parent social aggression in their own peer relationships, (b) whether parents' social aggression was related to their use of psychological control within the parent-adolescent relationship (c) whether adolescents' and parents' social aggression was associated with changes in each other's social aggression over time, and (d) change in psychological control. Participants were 174 racially/ethnically diverse parent-adolescent dyads assessed longitudinally for four years. Adolescents were approximately 15-years-old at the first time point. The adolescent sample was 52% girls and 56% identified as White, 22% as Black or African American, 16% as Hispanic, and 5% as mixed race/ ethnicity. Ten percent of the parent participants were fathers. Parents self-reported their psychological control and social aggression, and their adolescents' teachers reported adolescents' social aggression. Hypotheses were tested using longitudinal structural equation modeling and a latent growth curve analysis. The hypothesized effect of parent's psychological control on parent's future aggression with their own peers was supported. Psychological control positively predicted parent aggression from T2 to T3 (β = .28, p < .05) and from T3 to T4 (β = .37, p < .05). Other hypotheses were not supported. The findings suggest that the parent-child relationship may influence the parent's functioning in their own peer relationships. Parents' peer relations seem to have important implications for their own wellbeing and the parent-child relationship.

Ethnic Group Differences in Bullying Perpetration: A Meta-Analysis

We examined ethnic differences in bullying perpetration in order to assess whether ethnic group membership was associated with higher involvement among (1) nonimmigrant and immigrant youth; and (2) White and visible minority youth (i.e., Black, Hispanic, Asian, Indigenous, and Biracial). Fifty-three studies (N = 740,176; 6-18-year-olds) were included in the meta-analysis. Results yielded very small and nonsignificant effect size differences across all group comparisons. Methodological moderator analyses indicated several differences across groups. Our findings provide initial support that the assessment of ethnicity as a descriptive variable is not sufficient to account for group differences in bullying perpetration.

Evaluating the genetic susceptibility to peer reported bullying behaviors

Bullying is a significant public health concern with lasting impacts on youth. Although environmental risk factors for bullying have been well-characterized, genetic influences on bullying are not well understood. This study explored the role of genetics on early childhood bullying behavior. Participants were 561 children who participated in a longitudinal randomized control trial of a preventive intervention beginning in first grade who were present for the first grade peer nominations used to measure early childhood bullying and who provided genetic data during the age 19-21 year follow-up in the form of blood or saliva. Measures included a polygenic risk score (PRS) derived from a conduct disorder genome wide association study. Latent profile analysis identified three profiles of bullying behaviors during early childhood. Results suggest that the PRS was significantly associated with class membership, with individuals in the moderate bully-victim profile having the highest levels of the PRS and those in the high bully-victim profile having the lowest levels. This line of research has important implications for understanding genetic vulnerability to bullying in early childhood.
