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…

Developing accurate and equitable screening protocols can lead to more targeted, efficient, and effective, teen dating violence (TDV) prevention programming. Current TDV screening protocols perform poorly and are rarely implemented, but recent research and policy emphasizes the importance of leveraging more trauma-focused screening measures for…

Despite the importance of peer relationships in college, limited research has explored factors protecting students from the development of relational aggression and victimization, despite evidence of the manifestation of these phenomena. This study explored associations between negative emotional states, mindfulness and self-compassion, and…

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…

Background: Aggressive behaviour (AB) and non-suicidal self-injury (NSSI) are common in people with mild intellectual disability or borderline intellectual functioning, leading to adverse consequences for themselves and those around them. Method: We investigated the relationship between AB (both total and physical in particular) and NSSI and risk…

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. One in 10 public schools reports at least one case of serious violent crime, such as aggressive bullying,…

Attention deficit/hyperactivity behaviors in children are often unnoticed until they reach school age; however, evidence suggests that attention deficit hyperactivity disorder (ADHD) tends to develop at an earlier age. Recent studies also indicate that perinatal maternal mental health is associated with ADHD symptoms in offspring. This study…

In this study, we identified the specific discipline decision situations (i.e., vulnerable decision points [VDPs]) that contribute most to racial discipline disparities from a sample of 2020 schools across the United States. We also examined how much VDPs contributed to overall discipline disparities and the extent which there was similarity among…

To identify factors in adolescence that predict the onset of sexual violence in adolescence and young adulthood. Data were analyzed from six survey waves of the longitudinal Growing up with Media Study (2008-2018) conducted in the USA. Participants were 778 youth 13-18 years old at baseline, who completed online surveys assessing sexual violence…

Experiences of dating violence are widespread among adolescents. Therefore, increasing the understanding on the developmental antecedents is crucial. However, most existing studies involve cross-sectional designs, which poses a challenge in better understanding the developmental precursors of dating violence victimization. To address this, we…

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…
