What term refers to the level of a person's confidence in his or her ability to successfully perform a behavior?

• A. Self-Efficacy
• B. Motivation
• C. Cognition
• D. Health Literacy

Answer: (A)

Self-efficacy is the belief in your own ability to succeed at a specific task or behavior. That confidence plays a crucial role in whether you start a behavior, how much effort you put in, and how you persist when obstacles appear. When someone feels capable of performing a health-related action—like sticking to a daily exercise routine or following a new medication schedule—they’re more likely to plan steps, stay motivated, and keep going after setbacks. This differs from motivation (the desire to act), cognition (the thinking processes involved), and health literacy (the ability to understand and use health information). So the level of confidence in actually performing the behavior is the defining feature of self-efficacy.
