Which concept describes an individual's confidence in their ability to influence health outcomes?

The correct concept that describes an individual's confidence in their ability to influence health outcomes is self-efficacy. Self-efficacy refers to the belief in one's capabilities to execute behaviors necessary to produce specific performance attainments. This belief plays a critical role in how people approach challenges and makes a profound impact on their motivation and behavioral change.

When individuals possess high self-efficacy, they are more likely to engage in health-promoting behaviors, persist through difficulties, and recover from setbacks. In the context of health outcomes, a person who believes they can make positive changes—like exercising regularly or following a nutritional plan—is more likely to implement and maintain those changes effectively.

Other concepts such as perceived susceptibility relate to an individual's thoughts about their chances of experiencing a health issue; behavioral intention involves the motivation to perform a specific behavior; and cue to action refers to a trigger that prompts an individual to take action. While these concepts are relevant in health behavior frameworks, they do not specifically capture the essence of an individual's confidence in their ability to influence health outcomes as clearly as self-efficacy does.
