Peer victimization is a common concern in adolescence that includes both relational (e.g., exclusion, rumor spreading) and overt (e.g., hitting, threatening) forms (Crick & Bigbee, 1998). Relational and overt peer victimization have shown to be differentially associated with depressive symptoms, with relational peer victimization showing a…

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were…

Building durable peace through education requires addressing the gender ideologies and hierarchies that encourage both direct physical aggression and indirect harm through marginalization and exploitation. Although formal education systems are shaped by gendered patterns of social conflict, enmity, and inequity, schools can help young people to…

We examined whether the moderating role of cortisol in the relation between physical peer victimization and physical aggression was better accounted for by a diathesis-stress model or a differential susceptibility model using a multi-informant approach (direct observations, teacher reports, and parent reports) of 198 preschool-aged children…

An expanded Theory of Planned Behaviour (TPB; Ajzen, "Organizational Behavior and Human Decision Processes" 50:179-211, 1991, Ajzen, "Journal of Applied Social Psychology" 32:665-683, 2002) which incorporates affective, moral, and personal belief variables with Ajzen's original social, behavioural, and cognitive factors has not…

Racial microaggressions are defined as daily indignities directed towards disempowered racial groups that communicate hostile, derogatory, or negative racial slights (Sue et al. "American Psychologist," 62, 271-286, 2007b). The purpose of the present study was to investigate Indigenous Canadian university students' experiences of racial…

Many workshops about identifying, understanding, and responding to microaggressions have been designed and delivered to learners within health education. However, few workshops implement an antiracist pedagogical approach, and none presented in the literature have been created specifically for occupational therapy students. Anti-racist pedagogical…

Numerous studies consider competition and jealousy within an evolutionary framework, yet less is known about the relation between aggression vis-à-vis hypercompetitiveness (i.e., competing to win) and jealousy. We investigated the longitudinal relations between hypercompetitiveness, jealousy, and aggression and the moderating role of gender in a…

Despite the well-established protective functions of guilt across childhood, its underlying physiological mechanisms have received little attention. We used latent difference scores (LDS) to model changes in children's (N = 267; 4- and 8-year-olds, 51% girls) skin conductance (SC) and respiratory sinus arrhythmia (RSA) while they imagined…

Drawing on semistructured interviews with Canadian Grade 4 to 12 students, this article uses a feminist lens to explore gendered and sexualized bullying and cyberbullying among children and youth. Our findings indicate that while boys' roles and behaviors were frequently made invisible, girls were typically spotlighted, blamed, and criticized.…

Objective: This study examined the prospective relationship from student inattention symptoms to changes in their psychological need satisfaction (PNS) during their transition to secondary school. In doing so, it has explored whether this temporal association was moderated by teachers' involvement (TI). Method: A sample of 688 students (46% male;…

Previous research indicates that the disproportionate distribution of income within society is associated with aggression and violence. Although research has been conducted identifying the relationship between income inequality and bullying victimization and perpetration, little is known about possible mediators. We investigated the association…

The proportion of foreign-born population in Canada is at the highest it has been in 70 years. Such an increase in immigration is projected to account for 100 percent of the population growth by 2026. The children of families arriving from different parts of the world into Canada's multicultural mosaic are commonly believed to have an easier time…

This study examined the moderating role of classroom injunctive norms salience regarding social withdrawal and regarding aggression in the longitudinal association between these behaviors and peer victimization. A total of 1,769 fourth through sixth graders (895 girls, M = 10.25 years, SD = 1.03) from 23 schools (67 classrooms) completed a peer…

Although the effect of physical and relational (i.e., traditional) victimization on psychopathology is established, the interdependent contribution of cybervictimization is unclear. We test a longitudinal path model theorizing that (a) children's physical and relational victimization in Grade 4 or 5 is associated with more cybervictimization…
