Which concept relates to an individual’s belief about their own capabilities to affect their outcomes?

The concept of self-efficacy pertains specifically to an individual's belief in their own ability to achieve specific tasks or goals, which directly impacts their motivation and the effort they put into achieving those outcomes. Developed by psychologist Albert Bandura, self-efficacy influences how people approach challenges and how resilient they are in the face of setbacks. When an individual possesses high self-efficacy, they are more likely to perceive themselves as capable of making effective changes, maintaining persistence in difficult situations, and ultimately succeeding in their endeavors.

In contrast, social validity refers to the social appropriateness and significance of an intervention, outcome expectancies involve the anticipation of the consequences of a behavior, and behavioral intention describes a person's commitment to performing a certain behavior. While these concepts are interrelated within the framework of behavior change, self-efficacy specifically captures the essence of personal belief in one’s capabilities and how that belief affects behavior and outcomes.
