スポーツチームにおける集団効力感とチームパフォーマンスの関係の種目間検討

抄録

The purpose of this article is to evaluate the collective efficacy of sport teams and to investigate whether the relationships among collective efficacy, the behavior of sportspersons during a game, and team performance differs depending on the type of sporting event. Hence, we developed and examined a scale of efficacy to measure the above relationships in the first part of the study and applied this instrument in the second part of the study. The results of the first part of the study indicated that our scale consisted of 10 items with one common factor and had internal consistency, stability, construct validity, and criterion-related validity. In the second part of the study, we conducted a simultaneous analysis of several groups in order to investigate the above relationships. The results showed that the relationships among collective efficacy, the behavior of sportspersons during a game, and team performance differed depending on the type of sporting event. From these results, we inferred that the impact of different sporting events should be considered while examining the effects of collective efficacy on team performance.
