The purpose in this investigation was to determine whether or not goal orientation and self-efficacy level could predict the motivation to participate in adolescent male soccer players. Participants were 159 male soccer players aged 13 and 14 (M = 13.43, SD = .49). Multiple regression analysis was used to analyze data. Achievement/status and competition were positively predicted by ego orientation. Skill development was positively predicted by task orientation. Team affiliation, being active/movement, and fitness/energy were positively predicted by self-efficacy. Goal orientation and self-efficacy were not found to be significant predictors of fun and friendship.
