Which source of self-efficacy is derived from successfully completing a target behavior?

The correct source of self-efficacy that is derived from successfully completing a target behavior is enactive mastery experience. This concept refers to the idea that individuals gain confidence in their abilities through direct, personal experiences of success. When a person achieves a specific goal or task, they build a sense of competence and self-belief that reinforces their ability to perform that behavior in the future. This practical experience is the most powerful source of self-efficacy, as it provides tangible evidence of one’s capabilities.

In contrast, verbal persuasion involves encouragement and motivation from others, but it does not provide the individual with direct experience of success. Vicarious experience entails observing others successfully completing a behavior, which can increase self-efficacy by modeling success, but it is less impactful than personal experience. Psychological affective states refer to one’s emotional responses, which can influence self-efficacy but are not derived from the actual completion of a behavior. Therefore, enactive mastery experience stands out as the direct source of self-efficacy linked to personal achievement.
