Fan identification refers to the psychological connection that individuals have with sport teams. This study sought to determine whether fans possessing different levels of identification respond differently to the antecedents to aggressive spectator behaviors that are addressed by the theory of planned behavior. Fans of four professional sport teams (N = 231) were placed in one of three groups based on their scores for fan identification strength. Consistent with hypotheses, highly identified fans felt less control over their behavior at games than moderately identified fans and lowly identified fans. Contrary to hypotheses, however, neither attitudes towards aggression nor subjective norms on aggression differed between identification levels. Discussion centers on the relevance of the findings for the control of different types of aggression.
