Identification of factors influencing expectancies of successful performance in competitive youth sports is important to understanding the way in which children perceive and respond to this evaluative achievement situation. Therefore, in this field study involving 10- to 12-year-old female soccer players, intrapersonal factors affecting players' pregame personal performance expectancies were first identified. Soccer ability and self-esteem were found to be related to personal performance expectancies, but competitive trait anxiety was not Second, the impact of game outcome, the previously mentioned intrapersonal variables, and the interaction of game outcome and intrapersonal variables was examined by determining players' postgame team expectancies in a hypothetical rematch with the same opponent. The postgame findings showed that winning players evidenced higher team expectancies than tying and losing players. Moreover, the expectancies of tying players were low and, in fact, similar to those of losers. The results of this study successfully replicated and extended previous findings with young male athletes.
