低自尊在社會心理學、諮商輔導、教育與健康照護都相當受到重視，然而目前在國內外文獻中對於低自尊並沒有一致性的定義。本文使用Walker與Avant所提出的概念分析步驟，分析低自尊的定義、定義性特徵，並列舉典型、邊緣、相關及相反案例、前置因子、後果及實證參考指標，期望藉此增進護理人員對低自尊概念的釐清與了解，並運用於臨床照護中，落實以病人為中心的全人照護。

Although the issue of low self-esteem was valued in numerous fields including social psychology, counseling, education, and healthcare, few definition of low self-esteem has been universally acknowledged. The study aimed to explore the operational definitions and the core characteristics of low self-esteem in the literature and applied the techniques advocated by Walker and Avant to redefine low self-esteem from a perspective on the use of conceptual analysis. Besides, four representative types of clinical vignettes based on the revised conceptual definition of low self-esteem in the study were provided for improving the understanding and being helpful with the implementation of patient-centered holistic nursing care.
