Abstract: Examined the relationship between sport fandom and trait aggression in 117 college students (mean age 22.4 yrs). The Ss completed the Buss-Perry Aggression Questionnaire, the Sport Fandom Questionnaire, the Sport Spectator Identification Scale, and a questionnaire that assessed demographic information. In contrast to past work, this study yielded a significant relationship between fandom and aggression for men. (PsycINFO Database Record (c) 2004 APA, all rights reserved)
