Outline of Final Research Achievements

The objectives of this study were to develop a more general and versatile Collective Efficacy (CE) scale for Basketball, and to investigate relationships between CE, gender, and performance levels. More specifically, we examined the relationships between CE, cohesion, optimism, and “team performance” over the course of one season, using Hierarchical Linear Modeling.
The key findings of this study were as follows:1. Factor analysis revealed that the Collective Efficacy Scale for Basketball Offense was comprised of twenty-one items, using subscales for“tactics”,“characteristics”, and“adjustments”.; 2. The impact of CE and cohesion differed, depending on the team/group. ; 3. A team's CE was not affected by the optimism of individual team members. Moreover, CE and cohesion were significantly correlated, and the degree of coherence varied, depending on the team/group.; 4. Providing feedback to the coach using the CE scale was effective in improving a team's task-performance.
