The interaction between self-efficacy and sports performance

本研究では165人の日本人アマチュアゴルファーを対象に自己効力感の大きさ・強度とスポーツパフォーマンスとの関連について検討した。参加者の自己効力感はゴルフコンペ直前に測定され、そのデータを実際のパフォーマンスと比較し関連を調べた。結果として自己効力感の大きさと強度はその後のパフォーマンスに影響を与えており、特に大きさはパフォーマンスの促進に重要な要因となっていることがわかった。さらに、実際のパフォーマンスはその後の自己効力感に影響を与え、自己効力感とスポーツパフォーマンスに相互作用が認められた。Recently Bandura\u27s self-efficacy theory (1977) has been adapted to a variety of academic fields. The core of the theory suggests that self-efficacy is one of the psychological components that influence or change human behaviour. The present study focused on sports performance and examined how it interacts with self-efficacy. In this study the degree of self-efficacy was divided into magnitude and strength, and analysed separately. 165 Japanese amateur golfers (152 men, 13 women) were measured for their degree of self-efficacy just before competition. After competitions the degree of self-efficacy was compared with actual score. Our study found that the degree of both magnitude and strength have effect on subsequent performance. Magnitude was found to be a more influential factor of enhanced superior performance. On the other hand, it was found that the actual performance had a great influence on the degree of self-efficacy for future performance
