Self-efficacy is the belief that one is capable of performing in a certain manner or attaining certain goals. It is a belief that one has the capabilities to execute the courses of actions require to manage prospective situations. Unlike efficacy, which is the power to produce an effect (in essence, competence), self-efficacy is the belief (whether or not accurate) that one has the power to produce that effect. For example, a person with high self efficacy may engage in a more health related activity when an illness occurs, whereas a person with low self efficacy would harbor feelings of hopelessness.
