Which concept is central to social cognitive theory and is a key determinant of motivation, affect, and action?

• A. Self-efficacy
• B. Habit formation
• C. Punishment
• D. Drive reduction

Answer: (A)

Self-efficacy is a belief about one's own ability to perform the actions needed to achieve a goal. In social cognitive theory, this belief drives motivation, affect, and action in a interconnected way. When people feel capable, they put in more effort, persist longer in the face of obstacles, and choose more challenging tasks, because they expect to succeed. This confidence also shapes emotional responses: higher self-efficacy reduces fear and anxiety about trying something new, leading to more positive feelings that support engagement. Finally, it guides behavior directly—people with higher self-efficacy are more likely to initiate activities, select effective strategies, and stay with them until outcomes improve.

In health promotion and nursing, this means a patient who believes they can manage medications or follow an exercise plan is more likely to start and maintain those behaviors, and a nurse who believes she can effectively educate a patient is more likely to tailor approaches and succeed.

Other concepts don’t capture this cognitive belief in personal capability as the central driver. Habit formation describes automatic routines formed by repetition, not the belief in capability. Punishment relies on consequences to change behavior, not on how confident someone feels about performing the behavior. Drive reduction focuses on physiological needs and internal drives, which come from a different theoretical perspective and don’t explain how confidence shapes motivation and action.
