In social cognitive theory, what role does self-efficacy play?

• A. It is not relevant
• B. It is a central determinant of motivation, affect, and action
• C. It only affects memory
• D. It only concerns external observation

Answer: (B)

Self-efficacy is the belief in one’s capability to organize and execute the actions needed to manage a task or situation. In social cognitive theory, this belief shapes whether a person will try a behavior, how much effort they’ll put in, and how long they’ll persist in the face of obstacles, as well as how they experience and regulate their emotions during the process. When someone has high self-efficacy for a task, they’re more likely to set challenging goals, persist through difficulties, and recover from setbacks, leading to greater motivation, better affect, and more effective action. It’s task-specific and context-dependent, so people can feel confident in one area (like exercising) while feeling less confident in another (like sticking to a diet under stress). Self-efficacy can be built through mastery experiences, observing others succeed, verbal encouragement, and interpreting bodily states in a way that supports capability. In health promotion, boosting self-efficacy helps patients initiate and sustain healthy behaviors, making it a central driver of motivation, affect, and action.
