自我效能（self-efficacy）是近幾年健康行為與病人教育研究中經常測量的一個變項，被認為是影響病人是否從事健康行為的一項重要因素，自從1977年心理學家Bandura提出自我效能的概念，在心理社會學界研究中廣泛運用，目前亦普遍運用在健康照顧領域，然而針對此概念之概念分析在國內仍欠缺，本文期望依Walker與Avant所提出的概念分析方法，清楚檢視自我效能的屬性及特徵，以便護理人員更清楚的運用於護理研究與護理實務工作中。

　　　　　Over the past decade, self-efficacy has become one of the most measured variables in studies on health behaviors and patient education. The concept was originally proposed in 1977 by Bandura, who initially promoted its use in social science research, especially psychology. It is now considered one of the most important determinants of health-related behaviors. Using Walker and Avant's concept analysis methods, the authors clarify the attributes and characteristics of self-efficacy. Refinement of this concept is proposed as a prerequisite for application to nursing research and practice.
