Assessing group efficacy: Comparing three methods of measurement

Two hundred eighty-two undergraduate students (94 groups) participated in a laboratory study designed to compare three methods of assessing group efficacy: an aggregate of self-efficacy perceptions, an aggregate of individual perceptions of group efficacy, and a consen-sual approach. Findings indicate that the three methods of measuring group efficacy do not differ in their capacity to discriminate high and moderate task-difficulty conditions nor do they differ in terms of their consistency, the magnitude of their relationship with goals, or the degree to which they are affected by performance. Findings suggest that any of the three methods can be applied when studying the effects of group efficacy, at least for tasks with low interdependence
