Enhancing Exercise Adherence through Self-Efficacy: Mechanisms, Moderators, and Interventions

Abstract

Regular physical activity provides substantial health benefits, yet adherence to exercise remains a challenge for many individuals. Self-efficacy, a core component of Social Cognitive Theory, has been identified as a critical psychological factor influencing exercise adherence. This review examines the theoretical underpinnings of self-efficacy and its role in promoting sustained physical activity. Key mechanisms through which self-efficacy affects exercise adherence include goal setting, self-regulation, and coping with barriers. Additionally, several moderators, such as demographic factors, social support, and health status, shape the selfefficacy–exercise adherence relationship. Intervention strategies designed to enhance selfefficacy, including behavioral techniques, social reinforcement, and digital health technologies, have demonstrated effectiveness in improving exercise adherence. Despite these advancements, gaps remain in understanding the long-term effects of self-efficacybased interventions and their applicability across diverse populations. Future research should explore longitudinal effects, cross-cultural variations, and the integration of emerging technologies to optimize exercise adherence interventions.
