In Social Cognitive Theory, what is the role of self-efficacy in behavior change and how can it be enhanced in a health promotion program?

• A. Self-efficacy influences initiation and persistence; can be enhanced through mastery experiences, vicarious experience, verbal persuasion, and managing physiological arousal.
• B. It determines genetic predisposition; enhanced by pharmacological aids.
• C. It only affects initial adoption; enhanced by punishment.
• D. It has no effect on behavior; enhanced by financial incentives alone.

Answer: (A)

Self-efficacy is a person’s belief in their own ability to perform a specific health behavior. In Social Cognitive Theory, that belief influences both whether someone starts a behavior and how persistently they pursue it when obstacles arise. A health promotion program can build self-efficacy by providing mastery experiences (giving people gradual, achievable steps so they experience success), vicarious experiences (modeling by peers or people similar to the participant who demonstrate the behavior), verbal persuasion (positive, credible encouragement and feedback that “you can do this”), and strategies to manage physiological arousal (teaching stress reduction and coping skills to reduce anxiety or fatigue that might undermine confidence). In practice, structure activities to create small wins, include relatable models, offer constructive praise, and teach relaxation or coping techniques. These elements collectively strengthen the belief in one's capabilities, which in turn supports initiation and persistence in healthy behavior changes.
