背景：在醫療環境中所發生的職場暴力事件遠遠高於其他職業場所，而在急診室工作的醫護人員更是遭受暴力攻擊的高危險群，然而當護理人員在遭受職場暴力後，隨之而來的是負向的情緒感受，其中包含生氣、無奈、心情沉重、憂鬱、恐懼、疲倦、乏力感、挫折感、缺乏耐性、害怕及自信心和自尊心下降等，這些情緒反應也影響著護理人員在事件發生後的調適行為，而負向的調適行為甚至會影響人員留任意願及影響臨床照護品質。
目的：探討急診護理人員遭受職場暴力後之情緒反應和調適行為之相關。
方法：本研究為橫斷式相關研究，以方便取樣方式收集資料，選取南部三家醫院之急診室年資滿3個月之護理人員為研究對象，以結構式自擬問卷包含「急診護理師基本資料」、「遭受職場暴力經驗調查」、「遭受職場暴力後之情緒反應量表」、「遭受職場暴力後調適行為量表」進行問卷調查，以G-Power軟體，估算需收案118位，加上問卷填答不完整率20%，預計收案148人，並以SPSS 統計軟體系統進行資料分析，以次數分配、百分比、平均數、最大值、最小值及標準差呈現描述性統計，以獨立樣本t檢定、One-way ANOVA、簡單線性迴歸分析各變項間的相關性。
結果：總共發出181份問卷，回收180份，回收率99.4%，扣除遺漏、填答不完整及無效問卷共15份，有效問卷為165份，有效填答率為91.16%，有效問卷中，有47位(28.5%)未曾於一年內遭受職場暴力事件，故最後收案118位急診護理人員，研究對象為女性居多，年齡介於31-40歲(43.2%)，急診總年資平均9.45年，婚姻狀況以未婚居多，且為非固定班的N2以上急診護理師；研究結果分析發現，急診護理人員遭受職場暴力後，呈現的情緒反應分佈前五項為：我覺得無奈(88.14%)、我感到生氣(84.75%)、我的心情沉重(65.25%)、我覺得悲傷(55.08%)及我變得憂鬱(45.76%)；而職稱和情緒反應強度(t = 2.06，p = .042)之關係，及職場暴力類型和情緒反應強度(F = 4.56，p = .012)之關係，皆呈現有顯著差異，在遭受職場暴力後的調適行為分析發現，急診護理人員使用正向調適行為的頻率(3.08+0.65)高於使用負向調適行為(1.70+0.47)，負向調適行為和所遭受職場暴力類型的項次(F= 4.74，p = .012 )呈現顯著差異，而情緒反應的強度和負向調適行為呈現正相關(γ= .593，p= .000)。
結論/實務運用：急診護理人員遭受職場暴力後其情緒反應會因職稱和暴力類型而有不同的情緒反應強度，而情緒反應強度越強其使用負向調適行為頻率越高，建議於護理師的臨床教育課程中導入認識及調節情緒反應的相關課程，避免增加急診護理人員在遭受職場暴力後使用負向調適行為的頻率，並提供給臨床主管，在處理職場暴力事件時能作為初步的情緒反應評估及即時引導人員降低使用負向調適行為。

SUMMARY
Workplace violence has been viewed as a serious problem in health care organizations, especially in the emergency department. After a workplace violence incident, health care providers often experience negative emotional responses and coping behaviors. Negative coping behaviors will further affect nurses’ job retention and quality of care. The purpose of this cross-sectional study was to explore emergency nurses’ emotional responses to workplace violence and their coping behaviors. We used convenience sampling to recruit 148 nurses, who has worked in the emergency department for at least 3 months in the southern Taiwan. We found that the top five emotional responses to workplace violence were feelings of bootlessness, anger, heaviness, sadness and depression in order. The most positive coping behavior was talking to colleagues, friends or family members. Leaving the scene immediately was the most frequently negative coping behavior. Overall, positive coping behaviors were seen more than negative coping behaviors. Job title and violence types were significantly related to emotional responses. The intensity of emotional responses was correlated to job title and violence types. Emotional responses and coping behaviors were positively related (ꭇ = .593, p ≤ .001). The stronger the emotional responses were, the more negative coping behaviors were shown. Therefore, we suggested the institution can provide courses to help nurses learn how to respond to workplace violence and develop appropriate coping strategies to reduce the negative coping behaviors.
