Orthogonality of achievement goals and its relationship to beliefs about success and satisfaction in sport.

The present study examined the relationship between dispositional achievement goal orientations and satisfaction and beliefs about success in sport. Participants were 333 students who were administered the Perception of Success Questionnaire (POSQ), Beliefs about Success, and Satisfaction/Interest/Boredom Questionnaires. Consistent with theory (e.g., J. G. Nicholls, 1989) and previous research, task and ego goal orientations were found to be orthogonal. Following an extreme group split of the task and ego subscales of the POSQ, results of a 2 × 2 (High/Low Ego; High/Low Task) multivariate analysis of variance revealed a significant interaction effect between task and ego orientation. Specifically, participants high in ego and low in task orientation believed effort to be less a cause of success while high task/low ego-oriented individuals were the least likely to attribute success to external factors. The findings are discussed in terms of their motivational implications for athletes.
