  abstract  = {Exposure to peer aggression is a major risk factor for the development of aggressive behavior in childhood and adolescence. Furthermore, peer aggression has the propensity to spread and affect individuals who were not exposed to the original source of aggression. The aim of this paper is to demonstrate that peer aggression is in many regards similar to a contagious disease. By presenting a program of research based on longitudinal and multilevel studies, we provide evidence for the contagious quality of aggressive behavior, show that individuals vary in their susceptibility to peer aggression, and describe group-level characteristics that moderate the influence of peer aggression. We discuss mechanisms that may explain how individuals catch aggressive behavior from their peers and how the effects on the development of individuals' aggressive behavior unfold over time. Further, we examine processes that may increase the risk of being exposed to peers' aggressive behavior. We conclude with discussing implications for future studies on the contagious nature of peer aggression.},

  abstract  = {Assessing anger regulation via self-reports is fraught with problems, especially among children. Behavioral observation provides an ecologically valid alternative for measuring anger regulation. The present study uses data from two waves of a longitudinal study to present a behavioral observation approach for measuring anger regulation in middle childhood. At T1, 599 children from Germany (6-10 years old) were observed during an anger eliciting task, and the use of anger regulation strategies was coded. At T2, 3 years later, the observation was repeated with an age-appropriate version of the same task. Partial metric measurement invariance over time demonstrated the structural equivalence of the two versions. Maladaptive anger regulation between the two time points showed moderate stability. Validity was established by showing correlations with aggressive behavior, peer problems, and conduct problems (concurrent and predictive criterion validity). The study presents an ecologically valid and economic approach to assessing anger regulation strategies in situ.},
