本研究目的在瞭解護理人員的專業承諾，並探討個人屬性、家庭狀況及工作背景與專業承諾的關係。採相關性研究設計，以方便取樣收集資料，研究對象為服務於高雄縣28所地區醫院之護理人員共670位，問卷回收575份，回收率為85.8％。為達研究目的，研究工具使用「護理專業承諾量表」，係採用國內呂桂雲於1998年發展之結構式問卷，獲得同意後使用。依研究目的及變項性質選擇適當統計方法，包括百分比、平均值、標準差、Pearson's相關、單因子變異數分析、事後比較及複迴歸分析等統計方法進行資料分析。 研究結果發現：（1）護理人員整體專業承諾總平均值2.80分（Range 1-4），屬於中等程度；各專業承諾因素分別「為專業努力意願」因素，平均值2.65分（Range 1-4）；「專業生涯涉入意願」因素，平均值3.04分（Range 1-4）；「專業生涯正向評價」因素，平均值2.76分（Range 1-4）；「專業價值認同」因素，平均值2.95分（Range 1-4）。（2）護理人員個人屬性中的婚姻狀況不同其「專業價值認同」呈顯著差異；技術學院及一般大學畢業的護理人員具有較高的專業承諾。（3）家人對護理工作的支持與專業承諾的四個因素均呈顯著正相關；小孩安置安心程度與「整體專業承諾」及「努力意願」、「生涯涉入意願」和「生涯正向評價」等三個因素呈顯著正相關。（4）經複迴歸分析發現僅「家人對護理工作的支持」會影響專業承諾的確定感，其解釋力達21％。（5）經對數迴歸分析發現「工作職稱」亦會影響專業承諾的確定感，其解釋力達8.5％。本研究結果可提供地區醫療機構護理管理者對招募和留任護理人員之參考。
