Self-efficacy refers to which of the following concepts?

Self-efficacy specifically pertains to an individual’s belief in their own abilities to succeed in particular situations or accomplish specific tasks. This concept is rooted in Bandura's social cognitive theory, which emphasizes that self-efficacy influences motivation and behavior. When individuals believe they can successfully perform a task, they are more likely to engage in that task and persist through challenges, ultimately leading to better performance and outcomes.

This belief system plays a critical role in various areas, including health, education, and sports, as it encourages individuals to set challenging goals and strive towards achieving them. High self-efficacy can lead to greater resilience, improved performance, and a lower likelihood of experiencing anxiety or stress when facing tasks or challenges.

In contrast, the other concepts present in the choices do not accurately capture the essence of self-efficacy. The ability to influence others' behaviors, defining one’s self-identity, and the perception of social support relate to broader psychological and social dynamics, but they do not focus specifically on the belief in one’s personal capability to succeed in tasks or situations.
