Understanding classroom-level correlates of preschool children's aggressive behavior is critical to identifying multiple avenues for intervention within schools. The present school-based study evaluated the reliability and validity of a classroom-level measure of physical and relational aggression and examined a social-ecological model to test…

Very few studies have identified the relationship between chronotype, sleep habits, and bullying/victimization in school and online contexts. The objective of this work is to identify predictors of frequency of bullying/cyberbullying in Portuguese pubescent and adolescent populations, such as chronotype and sleep aspects, controlling for gender,…

The socialisation of adolescent boys and girls takes place primarily online in virtual environments, where cyberbullying is one of the greatest current social dangers faced by that age group. Socio-emotional e-competencies (i.e., competencies that apply specifically to online environments) are a protective factor against cyberaggression and…

Bullying victimization is a very common, complex, and potentially damaging form of violence among children and adolescents. Bullying is defined as unwanted, aggressive behavior, which involves a real or perceived social power imbalance.

Moral disengagement (MD) refers to social-cognitive distortions that allow individuals to sidestep the self-regulatory processes that normally prevent immoral conduct. MD has been linked to bullying in childhood and adolescence, but most studies have used a cross-sectional design. Less is known about the longitudinal link. Therefore, the aim of…

Understanding the factors that motivate defending behaviour from an early age is crucial in informing effective intervention in bullying. However, relatively little is known about the social, emotional, and cognitive factors that predict young children's involvement in defending behaviour. This study investigated the concurrent role of social…

Bystanders play a key role in understanding the phenomenon of cyberbullying (CB). The main aim of this study is to explore longitudinal bidirectional relationships among cyberbystanders' reaction, CB perpetration, and CB justification. Participants were 1,105 adolescents (56.7% girls; M[subscript age] = 13.56, SD = 1.21) who answered self-reported…

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 study explored the relations among peer victimization (i.e., physical, relational, and cyberbullying victimization), learning flow, and academic achievement among elementary school students, using a seven-wave longitudinal design across four consecutive semesters. Participants were 1,440 students from Grades 3 and 4 in China (M[subscript age]…

Aggression is a known contributor to burnout and caregiver instability among direct support professionals (DSPs) caring for adults with developmental disabilities. However, few studies have explored the differential effects of aggression subtypes on caregivers and what implications these may have for intervention planning. This longitudinal study…

Narcissistic youth use social media to engage in a variety of self-promotional behaviors, which have either antisocial or prosocial characteristics. Differing views exist to explain the processes underlying narcissistic self-promotion, either characterizing these actions as intentional, or as impulsive. This study compared intentional…
