Which option best reflects how to enhance self-efficacy in interventions?

• A. Mastery experiences, vicarious modeling, verbal persuasion, and reducing anxiety and barriers
• B. Mastery experiences
• C. Vicarious modeling
• D. Verbal persuasion

Answer: (A)

Self-efficacy in behavior change is strengthened when interventions engage the four channels that shape beliefs about one’s capabilities: mastery experiences (successfully completing tasks), vicarious experiences (watching others succeed), verbal persuasion (encouragement and positive feedback), and managing physiological and emotional states to reduce anxiety and perceived barriers. The best option combines all four, because each channel supports belief in different ways and together they produce stronger, more durable self-efficacy than focusing on a single source. In practice, design tasks that are gradually challenging to create mastery experiences, include demonstrations or peer models, provide supportive feedback and encouragement, and add strategies to reduce anxiety and practical barriers—such as stress management, problem-solving, and removing logistical obstacles. This integrated approach best enhances self-efficacy within interventions.
