This study aimed to develop a “Scale for Teamwork in Sport” (STS) and examine its reliability and validity. We conducted a questionnaire survey of 432 athletes from 45 university sports teams across Japan. Based on exploratory factor analysis, 4 upper factors, 10 lower factors, and 40 items were extracted. The 4 upper factors, “team orientation”, “team leadership”, “team process”, and “communication” corresponded to Dickinson and McIntyre's (1997) conceptual model. The following results were obtained regarding the reliability and validity of the STS: 1) Its reliability was confirmed via sufficient internal consistency and temporal stability of Cronbach's alpha and retest reliability coefficients. 2) A significant correlation was found between the STS and factors of an existing scale. The average score for each STS factor of the team with high competition level was significantly high. Therefore, the criterion-related validity of the scale was supported. 3) As a result of confirmatory factor analysis, the goodness-of-fit of the model found in all 4 scales corresponded to the upper factors. In addition, covariance structure analysis was conducted on the validation model, and its goodness-of-fit was acceptable. Furthermore, significant path coefficients were confirmed among the elements, which excluded the path from “monitoring” to “coordination”. These results support the construct validity of the STS. These findings indicate that the STS has high reliability and validity and can evaluate teamwork in sports from a comprehensive and process perspective. Hence, a new simplified scale was developed that conformed to Dickinson and McIntyre's (1997) teamwork model and could be used in sports. These results provide new insight on team building.

This study aimed to develop a “questionnaire for shared mental models of a basketball team”, based on the classification of shared mental models by Cannon-Bowers et al. (1993), and examine its reliability and validity. We conducted a questionnaire survey with 453 players from university basketball clubs in Japan. Based on an exploratory factor analysis, four factors and 16 items were extracted. The four factors corresponded to the classification of the shared mental models. The following results were obtained regarding the reliability and validity of the “questionnaire for shared mental models of a basketball team”: 1) Its reliability was confirmed via sufficient internal consistency, temporal stability of Cronbach's alpha, and retest reliability coefficients. 2) A significant correlation was found between the developed scale and factors of an existing scale. The average score of each factor of the team with a high competition level was significantly high. Therefore, the scale's criterion-related validity was supported. 3) As a result of confirmatory factor analysis, the goodness-of-fit of the model was recognized. Additionally, the validity of the construct of the developed scale was supported. Thus, the “questionnaire for shared mental models of a basketball team” had high reliability and validity. Furthermore, it appropriately evaluated shared mental models in basketball. In conclusion, we developed a new simple scale that conformed to the classification of shared mental models by Cannon-Bowers et al. (1993) and could be used in the field of competition. The results of this study provide a new perspective on team building in basketball.

<p> バスケットボール競技の現場では、連続してシュートを成功させると、その選手はパフォーマンスに対する自信と成功への期待を高め、「シュートタッチ」やその後のシュート時の諸動作がスムーズになることから、シュートが入りやすくなると信じられている。このhot hand現象を支持する研究報告の例として、Smith(2003)はhot hand現象の生起に関して、成功体験による正の強化が、自己効力感を高めパフォーマンスを向上させるとしている。一方で、誤認知であり単なる偶然に過ぎないという報告もみられる。しかし、実際にシュートの連続成功場面における、シューターのシュート動作と心理状態の変化を検討した研究は見当たらない。そこで本研究では、hot hand現象の生起、及びその際のシュート動作と心理状態との関係について、男子大学生バスケットボール選手らに行ったインタビューデータの質的分析と、3ポイントシュートを課題とする連続シュート実験によって検討した。連続シュート実験では、二次元気分尺度(TDMS)を用いてhot hand現象が生起している際の感情状態を経時的に評価し、シュート動作を撮影した動画を用いて3次元動作解析を行った。</p>
