部活動における主将のリーダーシップが部員の集団効力感に及ぼす影響

The purpose of this study was to clarify the effects of captain’s leadership on member’s collective efficacy in their club activities. Data was collected from 60 members of 4 clubs at a university, excluding captains. The leadership of the captain of the club which they belonged to and their collective efficacy were measured. The result of a factor analysis showed that the captain’s leadership consisted of three factors; “guidance and advice to the members”, “management of members’ relationship”, and “pressure on members”. The result also indicated that collective efficacy consisted of two factors; “team’s solidarity” and “team’s effort”. Captain’s leadership type of each club was categorized based on the average of the evaluation score of the club members. Analyses of variance, using captain’s leadership type as an independent variable and the member’s collective efficacy as a dependent variable, were conducted. The results suggested that the captain’s leadership with low “guidance and advice to the members”, low “management of members’ relationship”, and high “pressure on members” was effective in promoting “team’s solidarity” and “team’s effort”. Results also suggested that the captain’s leadership with low scores of all 3 factors (“guidance and advice to the members”, “management of members’ relationship”, and “pressure on members”) was effective in promoting “team’s effort”.
