Social scientists believe that sport, on the one hand, is a reflection of sport in general and, on the other hand, represents a small world of large societies, so the anomaly observed in sport is a kind of indicator of anomaly in the whole society. Abnormal behavior of sports spectators is one of the negative consequences of competitive sports such as football, which can create false sensitivities towards this sport in different societies and lead to misbehavior among spectators, which in addition to the game process, also inflames society. Due to the importance of the subject under study, the present study has done a sociological study of factors affecting abnormal behaviors among 400 persons of the football spectators in Tehran in 2017. The research results showed that; The rate of abnormal behavior of the respondents was above average and the criterion variables were almost moderate, which indicates the existence of the necessary conditions to increase inflammation in critical conditions and could play a vital role in explaining the abnormal behavior of spectators. Also, the results of regression analysis of the research showed that the criterion variables; Player, coach and referee behavior, history of fights, type of media coverage, relationship with relatives and friends, socio-economic status and job failure were able to explain more than 59% of the changes in the predictor of abnormal behavior, including player behavior, The coach and the referee have a greater impact on the abnormal behavior of the spectators.
