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…

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…

Aggressive behaviour has negative consequences for students who are exposed to it and those who are aggressive. In addition to a number of negative consequences at the individual level aggression negatively impacts processes within the school. Successful methods of preventing and reducing aggressive behaviour at school often include activities…

Children who show elevated levels of indirect aggression (IA) from childhood to adolescence are at increased risks of experiencing detrimental outcomes. Some studies suggest that psychopathic traits could act as a predisposing vulnerability in the development of IA, but the contributions of all three dimensions of psychopathic traits in explaining…

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…

Increasing research has indicated associations between popularity goal and adolescents' social functioning. However, little is known about the processes intervening and moderating these associations. We examined whether popularity status insecurity explained the longitudinal associations of popularity goal with depression and social behavior among…

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…

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…

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…

The current study evaluates the concurrent relationship between parent ratings of executive functioning and maladaptive behavior among children and adolescents with Down syndrome and then repeats this evaluation using teacher reports. Parents and teachers of 63 school-age children with Down syndrome rated the child's executive functioning…

Adolescent marijuana use has become increasingly more problematic compared with the past; thus, understanding developmental processes that increase the liability of marijuana use is essential. Two developmental pathways to adolescent substance use have been proposed: an externalizing pathway that emphasizes the expression of aggressive and…

Alexithymia refers to an ineffectiveness in identifying feelings and emotions and their communication. In adolescence, it has been identified as a significant predictor of emotional dysregulation, depression, anxiety, especially in girls, and it is generally associated with higher levels of physical and verbal aggression. We investigated the…
