Building self-efficacy as a key for behavior change involves which of the following?

• A. Increasing knowledge
• B. Enhancing belief in ability to perform the activity
• C. Relying solely on social support
• D. Reducing effort needed

Answer: (B)

The main idea is that self-efficacy is about your belief in your own ability to perform a specific behavior. That belief directly influences whether you start the behavior, how much effort you put in, and how long you stay with it when challenges arise. In behavior change, cultivating that confidence—your belief you can actually do the activity—is what drives sustained action, not just knowing what to do.

So the best choice is enhancing belief in your ability to perform the activity. If you truly feel capable, you’re more likely to initiate and persist, even when it’s tough, because you trust you can overcome bumps along the way.

Increasing knowledge helps you understand what to do, but it doesn’t by itself guarantee you’ll believe you can do it. Relying solely on social support can help, but it doesn’t automatically build your own confidence in your ability. Reducing the effort needed might make the task feel easier, but the underlying driver of long-term change is the belief that you can do it, even when effort is required.
