Although cyber victimization has been suggested as a significant risk factor for the development of adolescents' depression, the underlying psychopathological process that mediates this relationship needs further exploration. Based on the psychological inflexibility model, this study aimed to examine cognitive fusion and experiential avoidance as…

The goal of this study was to provide key prevalence rates for experiences with cyberbullying among tweens (children between the ages of 9 and 12 years old). We were also interested in the extent to which tweens engaged in helping behaviors when they observed cyberbullying. American tweens (n = 1034; mean age = 10.52, SD = 1.12) completed an…

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…

In the present study, we sought to examine the relationship between perceived economic stress and adolescents' bullying victimization and extended previous literature by examining the mediating effect of self-esteem as well as the moderating effects of student-student relationships and gender in this association. The research hypotheses were…

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.…

This review aimed at identifying specific features of PYD interventions with a PA component that appear most promising at reducing bullying behaviors among pre- and early adolescents. We reviewed articles that included PYD interventions with a PA component among pre- and early adolescents aged 8-14 years from five databases and found seven studies…

The objective of this study is to compare the prevalence of bullying victimization and perpetration between a sample of gifted students and a sample of nongifted students, and their relationship in both groups with depression, stress, anxiety, and health-related quality of life (HRQoL). A cross-sectional design was performed with two comparison…

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…

Bias-based aggression at school in the form of homophobic name-calling is quite prevalent among early adolescents. Homophobic name-calling is associated with low academic performance, higher risky sexual behaviors, and substance abuse, among other adverse outcomes. This longitudinal study examined risk and protective factors across multiple…

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…

Bias-based cyberbullying involves repeated hurtful actions online that devalue or harass one's peers specific to an identity-based characteristic. Cyberbullying in general has received increased scholarly scrutiny over the last decade, but the subtype of bias-based cyberbullying has been much less frequently investigated, with no known previous…

This study aimed to analyze affiliations with violent peers as an underlying mechanism that associates ethnic harassment with violent behaviors among immigrant youth (N = 365; M[subscript age] = 13.93, SD = 0.80), and also identify the risk factors in this relation. The results revealed that identification with an immigrant peer crowd at school…

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…

This short-term, longitudinal study examines evidence that the level of popularity among adolescents' peer role models exacerbates the emotional impact of mistreatment by peers. We recruited 469 adolescents (255 boys, 214 girls; [X-bar] age = 12.7 years) from an ethnically diverse middle school and followed these youth for a 1-year period. We…

The current study used thematic analysis to examine school staff perspectives on the impact of the Olweus Bullying Prevention Program (OBPP) on school climate in terms of the quality of student-student and student-teacher relationships in two low-income, urban middle schools in the United States. Data were collected using focus groups and…
