Using Three Reporters to Identify Pre-Adolescent Peer Victims through Latent Profile Analysis

Peer victimization in early adolescence and maladjustment in adulthood

Studies report different effect sizes for associations between peer victimization and later maladjustment. A possible origin of this heterogeneity is the length of the interval between victimization and maladjustment assessments. Effect sizes might also vary as a function of reporter. Longitudinal data from TRAILS, a study of adolescents followed from age 11 to 29 (baseline n = 2229) were used to test whether peer victimization assessed from adolescents themselves, their parents, teachers, and peers predicted internalizing symptoms, thought problems, and somatic complaints at six follow-ups with a temporal distance of up to 19 years. Neither self- nor peer-reported victimization predicted later maladjustment. In contrast, parent-reported victimization stably predicted adult maladjustment. Teacher-reported victimization also predicted maladjustment but associations were weaker and largely non-significant when parent reports were accounted for simultaneously. Parent-reported peer victimization has traditionally played a minor role in bullying research as parents are usually not present when victimization occurs. The results of this study however suggest that parents should be listened to when talking about their offspring being victimized.

Neighborhood Resource Deprivation as a Predictor of Bullying Perpetration and Resource-Driven Conduct Symptoms

OBJECTIVE

Resource deprivation is linked to systemic factors that disproportionately impact historically marginalized communities, and theoretical work suggests that resource deprivation may increase risk for bullying behaviors. Bullying perpetration is an intransigent social problem and an early risk factor that perpetuates the school-to-prison pipeline. This study explored how resource deprivation (family- and neighborhood-level metrics) was associated with early childhood bullying behaviors and clinician-rated symptoms of psychopathology, while accounting for other known risk factors (early life stressors, traumatic events, parental arrest, domestic violence).

METHOD

Participants (306 children, mean age = 4.45 years) were enrolled in a longitudinal study (Preschool Depression Study) where demographics, clinician-rated assessments of psychopathology, and parent reports of social functioning were collected. Measures of bullying behaviors (bullying perpetration, generalized aggression, and victimization) were constructed. A cross-sectional approach was employed, and analyses examined the interrelations between race, bullying-related behaviors, resource deprivation, and psychopathology, while accounting for confounding variables, at the baseline assessment time point.

RESULTS

The bullying measure showed acceptable model fit (comparative fit index = 0.956, Tucker-Lewis index = 0.945, root mean square error of approximation = 0.061, standardized root mean residual = 0.052, normed χ2 ratio = 2). Neighborhood resource deprivation was more strongly associated with bullying perpetration (r = 0.324, p < .001) than generalized aggression (r = 0.236, Williams t303 = 2.11, p = .036) and remained significant when controlling for other known risk factors (parental arrests, domestic violence, stressors, traumas) and demographic factors. Bullying perpetration was linked with racial category, but the relation was fully mediated by neighborhood resource deprivation. Linear regression including bullying behaviors and symptoms of clinical psychopathology suggested that resource deprivation specifically led to increases in bullying perpetration (t = 2.831, p = .005) and clinician-rated symptoms of conduct disorder (t = 2.827, p = .005), which were attributable to increased rates of resource-driven conduct symptoms (bullies, lies to obtain goods, stolen without confrontation).

CONCLUSION

Resource deprivation is strongly and specifically associated with increases in bullying perpetration. Children growing up in impoverished neighborhoods show significant increases in resource-driven conduct behaviors, yet interventions often target individual-level factors. These results highlight the need to target social inequity to reduce bullying perpetration and suggest that interventions targeting neighborhoods should be tested to reduce bullying in early childhood.

PLAIN LANGUAGE SUMMARY

Resource deprivation disproportionately impacts historically marginalized communities and may increase risk for bullying behavior. This study explored the relationships between neighborhood resource deprivation and social health behaviors and psychopathology in preschool-aged children (N = 306) in the St. Louis metropolitan area. Neighborhood resource deprivation was significantly linked to increased bullying perpetration (r = .324, p <.001) and accounted for other conduct symptoms. Results highlight the need to view neighborhood resources as a treatment target for reducing bullying perpetration in young children.

School bullying in children and adolescents with neurodevelopmental and psychiatric conditions: a systematic review and meta-analysis

BACKGROUND

Bullying is a common form of violence among children and adolescents. Young people with neurodevelopmental or psychiatric conditions might have an increased risk of bullying victimisation and perpetration. We aimed to assess the odds of bullying involvement and its association with mental health measures in these populations.

METHODS

In this systematic review and meta-analysis, we searched PubMed, ERIC, Psychology and Behavioural Sciences Collection, Web of Science Core Collection, PsycArticles, and PsycInfo databases from inception up to Aug 8, 2023, and included articles reporting data on bullying outcomes of current bullying (within the past year) among children and adolescents (aged 4-17 years) with a diagnosis of a neurodevelopmental or psychiatric condtion provided by a health professional. Bullying type was classified as traditional (physical, verbal, or relational) or as cyberbullying (intentional and repeated harm inflicted through electronic devices and social media), and bullying involvement was classified as victimisation, perpetration, and perpetration-victimisation. Mental health measures were collected and the associations with bullying involvement assessed. We used random-effects meta-analyses to estimate prevalence and odds ratios (ORs) for bullying involvement. Heterogeneity was assessed using the I2 statistic, and publication bias was tested with Egger's regression. This study is registered with PROSPERO, CRD42021235043.

FINDINGS

We included 212 studies in the meta-analysis. The total sample comprised 126 717 cases (mean age 12·34 years [SD 1·82], 37·6% girls) and 504 806 controls (12·5 years [SD 1·86], 47·6% girls). For traditional bullying, the pooled prevalence was 42·2% (95% CI 39·6-44·9) for victimisation, 24·4% (22·6-26·3) for perpetration, and 14·0% (11·4-17·1) for perpetration-victimisation. For cyberbullying, the prevalence was 21·8% (16·0-28·9) for victimisation, 19·6% (13·4-27·7) for perpetration, and 20·7% (8·4-42·6) for perpetration-victimisation. Compared with controls, young people with neurodevelopmental or psychiatric conditions were more likely to be involved in traditional and cyberbullying as a victim (OR 2·85 [95% CI 2·62-3·09] and 2·07 [1·63-2·61]), perpetrator (2·42 [2·20-2·66] and 1·91 [1·60-2·28]), and perpetrator-victim (3·66 [2·83-4·74] and 1·85 [1·05-3·28]). Bullying involvement was associated with higher scores in mental health measures in young people with neurodevelopmental or psychiatric conditions, particularly internalising symptoms and externalising symptoms.

INTERPRETATION

Our study underscores bullying involvement as a prevalent risk factor in young people with neurodevelopmental or psychiatric conditions that might add to their disease burden through its negative effects on mental health. Interventions targeting these vulnerable populations are warranted to improve their mental health and their future social integration.
