背景：心理韌性是心理健康與復元歷程中的重要概念，攸關個體面對逆境、創傷或疾病時的適應能力，並影響其心理健康與生活品質。然而，由於不同學科對心理韌性的定義不盡相同，且常與因應能力及復元等相關概念混淆，使其概念內涵與界定特徵尚未獲得一致共識。因此，本文旨在釐清心理韌性於心理健康脈絡中的概念內涵與界定特徵。方法：本文依據Walker & Avant (2019) 八步驟概念分析法，分析 2015 至 2025 年間 PubMed、Ovid、CINAHL 及 PsycINFO 資料庫之相關文獻，以釐清心理韌性於心理健康脈絡中的概念內涵，並透過典型案例、邊緣案例、相關案例及相反案例闡明其定義性特徵。結果：心理韌性具有三項核心界定屬性，包括維持逆境下的心理與情緒穩定、運用內外在資源進行適應性因應，以及展現逆境後的恢復與成長；其前置因子包括個人、人際及環境因素；後果則涵蓋臨床、心理及社會層面的正向結果，包括症狀穩定、情緒福祉提升、功能恢復及生活品質改善。實證參考指標主要為評估適應性因應、情緒調節及復元結果之心理韌性相關測量工具與指標。結論：心理韌性是一種促進個體正向適應逆境並實現復元的動態且多面向歷程。本文有助於增進醫療照護人員對心理韌性的理解，並可作為未來評估工具發展、臨床介入措施設計及復元導向心理健康照護之理論參考。

Purpose: To clarify the concept and defining attributes of psychological resili-ence within the mental health context and provide a theoretical foundation for future research, assessment, and clinical practice. Design: A concept analysis. Methods: Walker and Avant’s eight-step concept analysis method was applied. Relevant theo-retical and empirical literature published between 2015 and 2025 was retrieved from the PubMed, Ovid, CINAHL, and PsycINFO databases. The defining attributes, an-tecedents, consequences, empirical referents, and illustrative cases of psychological resilience were identified and analyzed. Results: Three defining attributes of psy-chological resilience were identified: psychological and emotional stability under adversity, mobilization of internal and external resources for adaptive coping, and restoration and growth following adversity. Antecedents included individual, inter-personal, and environmental factors that support resilience development. Conse-quences comprised clinical, psychological, and social outcomes, including symptom stabilization, emotional well-being, functional recovery, and improved quality of life. Empirical referents included validated resilience instruments and related indi-cators that assess adaptive coping, emotional regulation, and recovery outcomes. Conclusion: Psychological resilience is a dynamic and multidimensional process that enables individuals to adapt positively and recover from adversity. Clarification of this concept provides a theoretical foundation for the development of assessment tools and clinical interventions, thereby contributing to the promotion of mental health and recovery-oriented care.
