Connections between prosociality and antisocial behaviors have been recognized; however, little research has studied their developmental links longitudinally. This is important to illuminate during early adolescence as a sensitive period for social development in which prosociality could protect against the development of later antisocial…

Although there is a body of literature that addresses victimization of adolescents based on their membership in stigmatized groups, there is little that focuses on this type of aggression delivered digitally. Furthermore, the extant literature typically focuses on the targets of such aggression, but scant attention has been paid to the aggressors.…

Prior research on bullying victimization has often explored the behavior from a binary perspective in which victims and non-victims are examined. However, there has been an increasing amount of literature taking a more nuanced approach towards different subtypes of victims in recent years. This study sought to examine heterogeneous patterns of…

This study examined beliefs about aggression and self-efficacy for nonviolent responses as mediators of longitudinal relations between exposure to violence and physical aggression. Participants were a predominantly African American (79%) sample of 2705 early adolescents from three middle schools within urban neighborhoods with high rates of…

The main aim of this study was to examine one potential mediator of the prospective association between depressive symptoms and peer victimization: sadness rumination. Data were collected from 302 early adolescents (M[subscript age] = 10.53, SD =0.16; 55.3% girls), at two waves, 1-year spaced, using self-reports. Depressive symptoms preceded…

Effectively coping with peer victimization may be facilitated by deploying attention away from threat (i.e., bullies, reinforcers) and toward available support (e.g., defenders). To test this premise, 72 early adolescents (38 girls; M[subscript age] = 11.67, SD = 8.14 months) watched video clips of youth actors portraying a bully aggressing…

Although substantive research has shown that a positive perceived school climate is an essential protective factor for cyberbullying among adolescents, little research revealed the mechanisms underlying this relationship. This study examined whether normative beliefs about aggression mediate the association between a positive perceived school…

This study examined the links between seven specific mechanisms of moral disengagement and indirect bullying, direct bullying, and pro-aggressive bystander behavior. In addition, the moderating role of gender on these associations was examined. Participants were 317 Swedish students in Grades 4 to 8 (X-bar[subscript age]=12.6, SD = 1.35; 62%…

The current study was designed to assess early adolescents' response evaluation and decision for hypothetical peer victimization vignettes. Participants were 336 (59% girls; X-bar age = 12.55) seventh and eighth graders from one school in the Midwestern United States. Adolescents read a hypothetical online or offline social situation and answered…

We used latent growth curve analysis to extend research on associations between early puberty and adverse peer relations by examining the role of pubertal timing in the developmental trajectories of peer victimization and offending from early- to mid-adolescence. We made use of three-wave longitudinal data collected annually from a cohort of…

Identifying factors that influence peer aggression and victimization is important because of their high prevalence rates and associated negative outcomes during early adolescence. Limited research has examined the impact of environmental and contextual factors, such as school climate, on peer aggression and victimization. This study longitudinally…

Victimization in early adolescence can have severe negative consequences later in life. Friendships are especially important in this time period. The present study investigated friendship selection and influence (contagion) processes with regard to victimization, as well as prosocial and aggressive characteristics of victims' friends. Using social…

In a previous study, reactive criminal thinking or cognitive impulsivity mediated the relationship between parental knowledge and delinquency. This study sought to determine whether cognitive impulsivity also mediated the relationship between parental knowledge and childhood aggression. A path analysis was performed on a sample of 438 early…

The present study investigated the effect of descriptive and injunctive norms of peers, parents, and favorite celebrities on adolescents' negative online behavior toward celebrities. The sample consisted of 1,255 adolescents ([X-bar][subscript age] = 14.17, SD = 0.47). Adolescents indicated what their peers, parents, and favorite celebrities think…

The complex temporal associations among moral disengagement, moral emotions, and aggressive behavior were investigated within a short-term four-wave longitudinal study in a sample of early adolescents (at T1: N = 245; M[subscript age] = 12.16 years; SD = 0.85). Moral disengagement and aggressive behavior were investigated by validated self-report…
