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.

AbstractNumerous studies have reported that children and adolescents who are overweight are more likely to get bullied, yet the literature is replete with methodological limitations. We examined the transactional associations between peer victimization and body mass index (BMI), considering potential mediating (body dissatisfaction) and moderating (biological sex) factors. Participants (n = 631) came from the McMaster Teen Study, where students were assessed annually between Grades 5–11, approximately half were girls (53.9%), and the majority were white (76.4%). Peer victimization (from Grade 5) and body dissatisfaction (from Grade 6) were self‐reported by students, while parents reported their child's height and weight (from Grade 5). Cascade models were built up sequentially using path analysis across 2‐year increments (Grades 5, 7, 9, and 11). The final model had excellent fit to the data (χ2 = 73.961, df = 66, p = 0.234). Grade 5 peer victimization had a direct effect on BMI across a 2‐year period in girls (b = 0.59, SE = 0.21, p = 0.005) and boys (b = 0.82, SE = 0.30, p = 0.006), and an indirect effect on BMI via body dissatisfaction across a 4‐year period (b = 0.074, 95% CI = 0.012–0.152, p = 0.036). At no point did BMI directly increase risk for peer victimization, yet there were indirect effects via body dissatisfaction among girls but not boys. Peer victimization and body dissatisfaction were proximally and longitudinally related at every time point and there was a transactional association in late‐adolescence among girls but not boys. Targeting modifiable factors in the social (peer victimization) and psychological (body dissatisfaction) domains may limit accelerated weight gain and the health risks associated with excess adiposity.

"Aggressive behavior during childhood and adolescence is an important risk factor for later serious and persistent adjustment problems in adulthood, including criminal behavior, school dropout as well as family-related and economic problems. Researchers have thus deployed considerable efforts to uncover what drives individuals to attack and hurt others. Each chapter explores the issue of aggression with an introduction, theoretical considerations, measures and methods, research findings, implications, and future directions"--

AbstractThis study examined the heterotypic continuity of aggression hypothesis (physical to indirect) using independent teacher reports of aggression drawn from a nationally representative sample of 749 Canadian girls and boys. Confirmatory factor analysis using an accelerated longitudinal design confirmed a two‐factor model of physical and indirect aggression that was stable across time, but not sex. Mean levels of indirect aggression were highest for girls whereas mean levels of physical aggression were highest for boys. Results of a series of path analyses indicated statistically significant cross‐lagged effects that varied by sex. Physical aggression at Time 1 (T1; aged six to nine years) significantly predicted increased levels of indirect aggression at Time 2 (T2; girls only) and Time 3 (T3; boys and girls). Indirect aggression at T1 predicted decreased physical aggression at T2 (boys only) and at T3 (boys and girls). These results offer support for the heterotypic continuity of aggression and underscore the usefulness of teacher reports in studies of childhood aggression.

Background: Significant disparities in utilization of mental health services exist among immigrant and Canadian-born populations. These gaps may be associated with a 'double stigma' – stigma related to being from a racialized background exacerbated by mental health stigma. Immigrant young adults may be particularly susceptible to this phenomenon, given developmental and social transitions from adolescence to adulthood. Aims: To investigate the joint effects of racial microaggression and mental health stigma on mental health and service use among first-generation immigrant and Canadian-born university students. Method: We conducted an online cross-sectional study among first-generation immigrant and Canadian-born university students (N = 1,280, Mage = 19.10, SD = 1.50). Results: Despite no differences in anxiety or depression symptoms, first-generation (foreign-born) immigrants were less likely to have received therapy and to have taken medication for mental health issues compared to Canadian-born participants. First-generation immigrants also reported experiencing higher levels of racial microaggression and stigma toward service use. Results suggest the presence of a double stigma, mental health stigma and racial microaggression, each explained significant additional variance in symptoms of anxiety and depression and medication use. No effects of double stigma for therapy use were found – while higher mental health stigma predicted lower use of therapy, racial microaggression did not predict unique variance in therapy use. Conclusions: Our findings highlight the joint effects of racial microaggression and stigma toward mental health and service as barriers to help-seeking among immigrant young adults. Mental health intervention and outreach programmes should target overt and covert forms of racial discrimination while incorporating culturally sensitive anti-stigma approaches to help reduce disparities in mental health service use among immigrants in Canada.

Indirect aggression is considered an evolutionarily adaptive mechanism that can improve female mating success. It has been hypothesized that indirect aggression toward romantic partners and peers is used more frequently by females who make appearance‐based comparisons and that these relationships are mediated by jealousy. Females (N = 528) currently in romantic relationships were surveyed. Results confirmed females who made more frequent appearance comparisons aggressed more often toward partners and peers. Low‐comparing females reported being more frequent targets of peer indirect aggression. Jealousy partially mediated the relationships between making frequent attractiveness comparisons and indirect aggression. Results are discussed as effort allocated toward deterring partner defection and fending off rivals, and the role of emotion as a motivational influence for aggression.

Jealousy is argued to be an adaptive emotion that coordinates the use of mate retention acts, denoting behavior intended to guard a relationship from rivals, to prevent infidelity, and to hinder defection from the mateship. Nevertheless, few researchers have examined these relations. We sampled 144 women and men in romantic relationships and found that anxious (unease over potential infidelity) and preventive (preventing one's partner from consorting with others) but not reactive (anger over a partner being unfaithful) jealousy positively predicted cost‐inflicting mate retention. Only anxious jealousy positively predicted benefit‐provisioning acts. Sex moderated the relations between reactive jealousy with cost‐inflicting and benefit‐provisioning behavior, such that reactively jealous women used more of both kinds of mate retention.

Adolescents rejected by peers are often targets of bullying. However, peer rejection is not a sure path to victimization. We examined whether characteristics valued by peers (i.e., attractiveness, wealth, academic, and athletic ability) moderated the relationship between peer rejection and victimization. We predicted rejected adolescents high on peer‐valued characteristics (PVCs) would receive fewer nominations for being victimized than adolescents with lower levels. Canadian students in Grades 6–10 (N = 549; Mage = 13.32, SD = 1.50) provided peer nominations for peer victimization, rejection, attractiveness, wealth, and academic and athletic competence. As hypothesized, each PVC moderated the relationship between peer rejection and peer victimization. No sex differences were found. This study demonstrates the buffering effects of nonbehavioral characteristics valued by peers.

AbstractResearch concerning temperament in children and adults with autism spectrum disorder (ASD) has suggested a consistent profile of low positive affect, high negative affect, and low regulation (Visser et al., 2016). One area receiving less attention is individual differences among children diagnosed with ASD. The primary objective of this study was to use a person‐centered approach to explore heterogeneity of early temperament precursors of regulation in a large sample of infants with elevated familial likelihood of ASD. Early precursors of regulation included temperament assessed at 6, 12, and 24 months whereas outcome measures were diagnosis of ASD, cognitive ability and adaptive behavior at 36 months. Participants included 176 low‐likelihood and 473 elevated‐likelihood infants, 129 of whom were diagnosed with ASD at 3 years. Results supported a three‐profile solution: a well‐regulated profile (high positive affect and high attentional focus and shifting), a low attention focus profile (higher attentional shifting compared to attentional focus), and a low attention shifting profile (higher attentional focus compared to attentional shifting). A higher proportion of children diagnosed with ASD were classified into the low attention shifting profile. Furthermore, children with the well‐regulated profile were differentiated from the other profiles by a pattern of higher social competence and lower dysregulation whereas children with the low attention focus profile were distinguished from the other profiles by higher cognitive ability at 3 years. The findings indicate that the combination of early positive affect with attention measures may provide an enhanced tool for prediction of self‐regulation and later outcomes.
