摘要：Soccer fans’ aggressiveness has serious consequences for individuals and society. However, its predictive factors have been poorly investigated. This study aimed to examine variables that predict soccer fans’ aggressiveness. This survey, correlational and cross-sectional research involved 210 participants, which were equivalent in crowd type (105 belonging to organized fan crowds and 105 not belonging to organized fan crowds), sex and age. The measurement instruments were: sociodemographic, occupational and behavioural questionnaires; the Fanaticism Scale for Football Fans; and the Buss and Perry Aggression Questionnaire. Results showed high aggressiveness in both groups and correlations between aggressiveness and fanaticism, sociodemographic and behavioural variables. Furthermore, the predictors of aggressiveness were fanaticism, age and time affiliated with the organized crowd. Therefore, it is concluded that sociodemographic and behavioural variables and fanaticism are important for understanding this phenomenon.
