Concept analysis and concept development are the terms used to refer to the process of clarifying the definition of concepts used in nursing. They are generally applied to the process of inquiry that examines concepts according to their level of development as seen in their internal structure, usage, representativeness, and relationships with other concepts, with the aim of promoting a better understanding. Much of the conceptual basis of nursing theory is derived from concepts already established in other disciplines, and a re-examination of these concepts to determine their relevance and appropriateness to nursing is important in determining the appropriateness of their application (McEwen, 2007). Albert Bandura first described the concept of self-efficacy in 1977 as the belief in one's ability to perform the actions required to achieve a goal. As a self-efficacy construct, self-confidence can be defined as a judgment about one's perception of one's abilities. Confidence in one's abilities directly affects one's performance. The ability to acquire new skills and knowledge is also affected by an individual's sense of self-efficacy. Unlike self-esteem, self-efficacy can differ significantly across subjects or skills. Self-efficacy is dynamic because it can change over time as new experiences and information are acquired. As self-efficacy increases, self-confidence also increases. Self-efficacy forms the foundation of human motivation, well-being, and personal achievement (Leigh, 2008). There are several techniques, methods and strategies when it comes to concept analysis. The Wilson method (1963/1969) identifies 11 steps to use in concept analysis.
