Relations entre cohésion et efficacité collective au sein d'équipes professionnelles masculines et féminines de basket-ball.

Abstract

The purpose of this study was to examine the relationship between cohesion and collective efficacy in professional basketball teams. A total of 66 male and 54 female French-speaking professional players from 20 teams completed Heuze and Fontayne’s (2002) Questionnaire sur l’Ambiance du Groupe and a collective efficacy measure designed to assess the athletes’ perceptions of their team efficacy in offense, defense, and total. Index of agreement, intraclass correlation, and eta-squared statistic supported the existence of group perceptions for the constructs. At group level, several positive correlations were found between the dimensions of cohesion and collective efficacy. However, sequential multiple regression analyses indicated that only Group integration-task was a significant predictor of collective efficacy and explained 38% to 65% of the variance of the collective efficacy scales. The implications of the results are discussed and future studies using multilevel statistical methodologies are recommended.
