Male ice hockey fans (N = 78) completed a battery of biographical, soc
ial, cognitive, and individual differences measures that had previousl
y been administered piecemeal to spectators found in attendance at gam
es. Participants' self-reported likelihood of joining in a crowd distu
rbance served as the dependent measure. The individual differences mea
sures included physical aggression, anger, impulsivity, psychopathy, s
ensation seeking, and public self-consciousness. All but public self-c
onsciousness was positively related to subjects' likelihood of escalat
ing a disturbance. Participants' age, number of accompanying males, th
e false consensus effect, number and recency of fights, and attending
in anticipation of watching player fights were also related to the dep
endent measure. A multiple regression analysis yielded a multiple R =
.807, accounting for 65% of the variance. The time since the participa
nt was last in a fight and liking to watch player fights emerged as si
gnificant predictors. (C) 1998 Wiley-Liss, Inc.
