We discuss the concept of self-efficacy, a person's belief in their ability to succeed in a particular situation. They explore the various factors that influence self-efficacy, including personal experiences, social models, verbal persuasion, and physiological states. We discuss the effects of self-efficacy on cognitive processes, performance, and mental and physical health. They further investigate the role of self-efficacy in overcoming challenges and achieving desired outcomes. Finally, we explore how self-efficacy is affected by social structures and group processes and how it can contribute to social change.
