Collective Efficacy, Group Goals, and Group Performance of a Muscular Endurance Task

The purpose of the study was to examine the relationships among collective efficacy, group goals, and group performance using an interdependent muscular endurance task in a controlled laboratory setting. Thirty-seven male (n = 14) and female (n = 23) triads performed two trials of maximum muscular endurance, completing measures of collective efficacy and group goals between trials. Results showed a high degree of correlation ( r range = .73 -.92) between collective efficacy, group goals, and group performance. Hierarchical linear regression analyses revealed that collective efficacy predicted significant variance in Trial 2 performance after controlling for performance on Trial 1. Group goals mediated the relationship between collective efficacy and group performance on Trial 2. Implications for theory and group performance in naturalistic settings such as sport teams are discussed.
