Abstract
The authors performed 3 studies to investigate the effects of social-cognitive variables on physical effort perseverance. Linear hierarchical regressions indicated that task-specific variables and perceived ability or competence accounted for the majority of perseverance variance in all 3 studies. The strongest single predictors in this cluster of variables were perceived competence, confidence, and readiness to invest effort. Physical self-health and ability accounted for a lesser portion of effort perseverance variance, with self-presentation confidence being the major single predictor in this cluster. The goal orientation cluster accounted for the least amount of effort perseverance variance. Together with task-specific confidence and the readiness to invest effort, as well as determination and commitment and competence, the findings support the contention that task-specific efficacious beliefs to a large extent determine persistence and endurance behaviors.
