I think I can, I think I can, is a famous phrase from a beloved children's book called The Little Engine That Could. This phrase also emulates what Resnick considers one of the main pillars of self-efficacy theory (2003). Self-efficacy is an individual’s opinion of their ability to accomplish a task (Resnick 2003). The theory itself is based on previous research on social cognition and asserts that a person's thoughts regarding their abilities are based on life experiences and environmental factors that directly influence their behavior (Resnick 2003). Building on this earlier research by Albert Bandura, Resnick states that there are four subparts to support the overall theory, namely enactive acquisition, vicarious experience, verbal persuasion, and physiological feedback (Resnick 2003 ). All these pillars strengthen the individual's confidence and belief in their own self-efficacy and enable them not only to set goals, but also to achieve them (Bandura 1977). These four segments will be analyzed individually in order to explain the theory of self-efficacy and how it can be implemented in nursing practice. will be reached again (Resnick 2003). Enactive impairment is this belief in continued success in similar activities after trying said activity (Bandura 1977). For every person, there is a mental barrier when it comes to setting goals and trying new things (Resnick 2003). Self-efficacy is not only the ability to set goals, but also having the confidence to achieve those goals (Bandura 1977). If an individual believes that a goal is achievable but does not think middle of paper ......f-effectiveness and therefore more independence.Works CitedBandura, A. (1977).
