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 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…

Spanking and parental verbal aggression are potentially toxic stressors that can negatively affect children's academic achievement by disrupting mental skills like executive function. Yet little empirical evidence has been provided for this mediating pathway. This study used data from the Early Childhood Longitudinal Study Kindergarten Cohort of…

Three generations of developmental epidemiologically based randomized field trials of the Good Behavior Game (GBG) have been delivered to Baltimore elementary schools. With the collaboration of family and community partners, all three trials were directed at decreasing proximal targets of aggressive behavior and improving learning in first-grade…
