Background: Aggression in residential youth care institutions is a frequent problem. Objective: The present short-term longitudinal study examined individual and institutional predictors of aggression in a group of 198 adolescents placed in open, semi-secure and secure residential institutions from the perspective of the importation and…

The goal of this cross-cultural study was to analyze and compare the cybervictimization and cyberaggression scores, and the problematic Internet use between Spain, Colombia and Uruguay. Despite cultural similarities between the Spanish and the South American contexts, there are few empirical studies that have comparatively examined this issue. The…

Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

Exposure to deviant friends has been found to be a powerful source of influence on children's and adolescents' aggressive behavior. However, the contribution of deviant friends may have been overestimated because of a possible non-accounted gene-environment correlation (rGE). In this study, we used a cross-lagged design to test whether friends'…

Most researchers on media and aggression have examined the behavioral effects of viewing physical aggression in the media. Conversely, in the current study, I examined longitudinal associations between viewing "relational aggression" on TV and subsequent aggressive behavior. Participants included 467 adolescents who completed a number of…

Witnessing intimate partner violence (IPV) and child maltreatment may place children on a lifelong trajectory toward violence. The primary aim of this research was to examine the associations between exposure to violence at home and two forms of violence in close relationships in Spanish adolescents: child-to-parent violence (CPV) and dating…

This study examines the effects of peer victimization by verbal, physical, and relational bullying on Korean adolescents' self-worth, disconnect to peers, school engagement, and academic achievement. A two-year longitudinal survey on 3,266 sixth-graders attending school in Seoul, Korea was used. Multivariate regression results controlling for…

Growing up in poverty increases youth risk for developing aggressive behavior problems which, in turn, are associated with a host of problematic outcomes, including school drop-out, substance use, mental health problems, and delinquency. In part, this may be due to exposure to adverse school contexts that create socialization influences supporting…

To investigate the developmental course of aggression and peer victimization in childhood and adolescence, distinct subgroups of children were identified based on similarities and differences in their physical, verbal and relational aggression, and victimization. Developmental continuity and change were assessed by examining transitions within and…

The 'terrible twos' are often associated with increased temper tantrums, noncompliance and aggression. Although some expression of these behaviors is normal, whether early individual factors can predict which children are most at risk of frequent or prolonged emotional and behavioral problems is of increasing interest. The current study of 6,067…

The purpose of the present study is to examine bullying perpetration and social intelligence (SI), which is a sociocognitive characteristic that has been proposed as a possible regulator of traditional and cyberbullying. We compared SI for perpetrators and nonperpetrators of traditional bullying and/or cyberbullying and examined longitudinal…

The purpose of the study was the theoretical justification and experimental verification of content, complex forms and methods to ensure effective prevention and psycho-pedagogical correction of bullying in school. 53 teenage students from Kazan took part in the experiment. A complex of diagnostic techniques for the detection of violence and…

The aim of this study was to examine the role of publicity (private versus public) and medium (face-to-face versus cyber) in adolescents' coping strategies for hypothetical victimization, while also considering culture. Participants were adolescents from China, Cyprus, the Czech Republic, India, Japan, and the United States. The study also…

This study examined the reciprocal longitudinal relations between homophobic attitudes and homophobic bullying at school. Furthermore, the study also assessed the roles of exposure to homophobic bullying at school, homophobic language at home, and previous social interaction with individuals who identify as lesbian, gay, bisexual, or transgender…

Poverty is a well-established risk factor for behavior problems, yet our understanding of putative family mediators during early childhood (i.e., before age 5 years) is limited. The present study investigated whether the association between poverty and behavior problems during early childhood is mediated simultaneously by perceived parenting,…
