In adolescence, being rejected by one's peers is positively associated with aggression. However, whether self-perceptions of being rejected or accepted by peers, and biases in these perceptions, are linked to aggression remains unclear, as the literature points to 2 perspectives: Youth are more likely to be aggressive when they (a) know or believe…

Student perpetrated violence against teachers is widespread, yet few studies differentiate teacher experiences of violence by school level (i.e., elementary, middle, and high school). This study, based upon 2,558 pre-kindergarten through 12th grade teacher survey responses, revealed differences in types of student aggression against teachers by…

Adolescent behavior now occurs offline and online. Frequently studied and treated independently, the relationship between offline problem behaviors and online risk taking is not well understood. This study asked whether there are any problematic behaviors predictive of online risk taking by high school students. Using a 2009 dataset of 2,077 high…

This research aims to examine the relationship between classroom management, classroom climate, and relational aggression and victimization in high school students. A total of 42 teachers and 2168 students from 5 high schools in Shenzhen, China participated in the study. Teachers completed a classroom management style scale, while students…

This exploratory study aims to broaden students' models of cyber-aggression behavior, with the Theory of Planned Behavior (TPB) by including additional constructs, namely cyber health, to predict youth cyber-aggression actions. The self-administered questionnaire was used to collect data from 291 students intentionally, aged 15 to 21 at secondary…

This study aims to analyse the relationship between moral disengagement mechanisms, aggression and bullying behaviour in 221 high school students between 11 and 17 years who took the Mechanisms of Moral Disengagement Questionnaire, The Aggression Questionnaire and the School Bullying Questionnaire. Findings suggest significant positive…

The research aims to examine the relationship between cyber bullying and self-disclosure. Participants of the study were 480 high school students who answered the scales. According to the results, the dimensions of cyber bullying; verbal cyber-aggression and exclusion, impersonation and visual-sexual cyber-aggression are negatively related to…

It is unknown whether sluggish cognitive tempo (SCT) is prospectively associated with depression in adolescence, and possible processes linking SCT to depression remain unexamined. Using a longitudinal study with three timepoints over a two-year period, the current study tested the indirect effects of SCT on depression via peer victimization,…

The beneficial relationship of school climate with various positive student outcomes has been demonstrated in several studies, though the relationship has not been thoroughly explored with regards to a student's likelihood of being suspended from school. The relationship of school climate and out-of-school suspensions was investigated using a…

Student victimization by school staff members has important potential consequences for students' academic achievement and physical and psychological outcomes. Several studies have shown that such victimization exists in multiple contexts and there is considerable variation in prevalence among contexts. This study examined the prevalence of student…

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…

As researchers and practitioners begin to take a bystander approach toward preventing bullying, which involves a power imbalance between two students, it is important to acknowledge that predictors of bystander intervention may look different in various groups of students. Though school connectedness has been suggested as a predictor, previous…

Few studies have been conducted to perform an in-depth examination of cyberbullying roles and to identify multifaceted factors associated with cyberbullying roles. Using Latent Class Analysis, the current study identified four cyberbullying roles (i.e., cyberbully, cyber victim, cyberbully victim, and noninvolved) based on the data from the…

Bullying bystanders' reactions are important for either stopping or perpetuating bullying behaviors. Given school-based bullying programs' focus on bystanders, understanding the associations between school-level factors and individual bystander responses can improve intervention efficacy. Data from 64,670 adolescents were used to examine bullying…

Most studies of school bullying in China are atheoretical. To fill the gap in the literature, we introduce criminological theories in an attempt to test propositions broadly derived from these perspectives in the study of physical bullying. Relying on data collected from 12 middle schools (Grades 7 to 9) in three cities with information on both…
