Background: Bullying has been associated with several adverse health outcomes, including substance use. However, little is known about the association between bullying and e-cigarette use. This study examined the association between bully victimization and the frequency of e-cigarette use. Methods: Data from the 2016-2017 Canadian Student Tobacco,…

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…

Victimization experiences, including traditional forms of bullying, discriminatory harassment, and cyber victimization, are associated with numerous detrimental consequences in adolescence and over the life course. The objective of the current study was to understand the relationships between nine experiences of victimization and mental health…

We examined bullying victimization spanning from before the pandemic to the two school years post COVID-19 onset in adolescents. We used survey data from Canadian secondary school students collected during the 2019-20, 2020-21, and 2021-22 academic years. Generalized Estimating Equations models were used to estimate the population average odds of…

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…

This preliminary study explored a person-group dissimilarity hypothesis in the context of adolescent sexual harassment. Theory suggests that victimized youth are expected to experience worse outcomes if they perceive victimization to be a rare experience among their peers. This study comprised 435 middle school students who reported on their…

Cyberbullying has become an important public health issue due to documented associations among victimization, perpetration, and greater likelihood of depression, substance abuse, anxiety, insomnia, and school-related problems for adolescents. Less is known, however, about how youth cope with cyberbullying and the types of services and supports…

School recess scholars have called for more research into collective relations between social, personal, and physical factors on students' engagement and enjoyment of recess. Overall and by gender, this study serves to investigate a proposed model among 355 elementary school students from victimization to enjoyment through peer belonging, positive…

The present study examined how school-age children's communicative decisions are influenced by the situation, their social partner, and their own characteristics (gender, shyness levels, and history of peer relationships). Children (8-12 years old, N=246) imagined themselves in social scenarios (depicted through comics) and indicated the…

Emotional reactions to peer victimization may increase risk for subsequent peer victimization. In the present study, we investigated whether shame mediated the development of chronic peer victimization, i.e., young people's experiences of being bullied persistently across time. We used a multiple mediation model to test the indirect effects of…

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…

Victimization has been primarily studied within the broader peer group, leaving other potentially important contexts, such as friendship cliques, unexplored. This study examined the role of popularity in identifying protective factors that buffer against victimization within early adolescents' (N = 387) friendship cliques. Previously identified…

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…

The Dual Failure Model suggests that peer victimization (social failure) and academic difficulties (academic failure) mediate the association between externalizing and later internalizing problems. The present study sought to better understand why children with externalizing problems develop later internalizing problems by testing the Dual Failure…
