A large survey of German (N = 3 403) and Israeli (N = 2 513) younger (age 11-14 yrs) and older (age 14-18 yrs) adolescents was conducted to reveal (a) their opinions and attitudes towards violence and aggression, (b) their personal engagement in aggressive and violent behaviors in and outside the school environment, (c) their attitudes toward physical activity, (d) their engagement in physical activity, and (e) the linkage between physical activity engagement and conductance of violence and aggression. The findings point out that there are more similarities than differences between German and Israeli adolescents concerning violence and aggression in and outside schools. No linkage between physical activity involvement and the extent of violent and/or aggressive acts is found. The findings pertaining adolescents’ opinions and attitudes toward aggression and violence and their behaviors in and outside school are encouraging
