Transformational leadership and childrens' aggression in team settings: A short-term longitudinal study

Social learning theory posits that one crucial way individuals learn how to behave is by observing and modeling the behavior of salient others. We conducted a short-term longitudinal study using multisource data on 183 teenaged ice hockey players (M age = 13.39 years) in 16 hockey teams to test the effects of 3 potentially salient leadership influences (team coaches, team players, and parents) on players' on-ice aggression. We tested a cross-level mediated model in which player aggression (penalty minutes) as measured by referees was the criterion variable. After controlling for prior levels of player aggression, team-level aggression mediated the relationship between team-level coach transformational leadership and player aggression. Parents' transformational leadership did not influence player aggression when assessed simultaneously with team-level coach transformational leadership. Consistent with social learning theory, the findings suggest that transformational leaders model prosocial behavior for followers.
