Abstract
Embedded in the theory of group cohesion and the expectancy-value model of achievement choice, the purpose of this study was to examine the predictive strengths of group cohesion on students’ motivation (expectancy-related beliefs and subjective task values) and motivational outcomes (exercise choice and class attendance) in college physical activity classes. Participants were 121 females enrolled in aerobics classes who completed questionnaires assessing group cohesion, motivational constructs, and exercise choice. Group cohesion constructs were significantly associated with motivation and motivational outcomes. These findings provide insight into how to design environments to promote motivation in physical activity classes.
