A structural equation model analysis confirmed that there is a significant positive correlation between the constructs of perception (i.e., aggressor and aggression), means (i.e., behavioral and emotional capabilities), and guidelines (i.e., scripts) and that behavioral performance (i.e., aggressive or nonaggressive behavior) is influenced significantly only by guidelines and means. It was also found that boys and young youth tended to present higher levels of aggressiveness across all constructs as compared to girls and older youths. Study limitations and implications are presented and discussed. The aim of this study was to explore the constructs that regulate verbal and physical aggression among youth. The model tested in this study is based on the general assertion that perception, means, and methods of action are interrelated and together influence behavioral performance. Specifically, it is maintained that the perception of aggressor and aggression, the emotional and behavioral means, and the manner by which they are to be applied regulate both verbally and physically aggressive behaviors. The study was conducted in a large metropolitan area in northern Israel and its suburbs. Participants consisted of 984 students enrolled in junior high schools. Tables, figure, references
