一位因慢性酒精使用問題一年內第四次入院。病人說：「我沒問題，我想戒隨時都能戒。」這是什麼例子？

在處理成癮問題的病人時，護理師經常會遇到病人使用各種心理防衛機轉來應對其行為的後果。否認 (denial) 是成癮病人最常見且最具挑戰性的防衛機轉之一。病人拒絕承認自己有問題，或低估問題的嚴重性，這會嚴重阻礙其尋求幫助和接受治療的意願。護理師需要認識到這種防衛機轉，並採用非批判性的、支持性的溝通方式，逐步幫助病人面對現實，理解其行為對自身和周圍人的影響，從而促使病人進入改變的階段。

When caring for clients with addiction, nurses frequently encounter the use of various psychological defense mechanisms in response to the consequences of the client's behavior. Denial is one of the most common and challenging defense mechanisms in clients with addiction. The client refuses to admit there is a problem or minimizes its severity, which seriously hinders his or her willingness to seek help and accept treatment. Nurses must recognize this defense mechanism and use nonjudgmental, supportive communication to gradually help the client confront reality and understand the impact of his or her behavior on self and others, thereby facilitating movement toward the stage of change.

成癮行為中的心理防衛機轉，特別是否認，在美國和台灣的臨床精神科護理中均被視為重要的評估和介入點。兩地的護理教育和實務皆強調理解這些機制對於有效治療成癮的重要性，因此在概念和應用上無顯著差異。
