本研究的目的在分析護理教師的工作壓力、組織承諾與專業承諾，並探討此三個變項間的結構模式關係。採橫斷式設計，以全國專科學校之護理教師為對象，發出5xx份卷，回收404份，回收率為82.6%。研究工具包括：工作壓力、組織承諾與專業承諾三個量表，均經過信度與校度檢測。結果顯示，教師的工作壓力、組織承諾與專業承諾均呈中高程度，工作壓力與組織承諾呈顯著負相關，組織承諾與專業承諾呈顯著正相關，工作壓力與專業承諾不呈顯著相關。結構方程模式顯示工作壓力直接而負向影響組織承諾(r=-.47)，組織承諾對專業承諾呈顯著之直接而正向的影響(r=.58)，工作壓力對專業承諾無直接之影響。本研究建議相關單位重視專科護理教師的壓力，提供必要之資源與支持，以免影響教師對學校的認同，進而影響其對專業的忠誠。 The purposes of this study are to explore work stress, organizational commitment and professional commitment, and to analyze their structural relationships among nursing educators. A cross-sectional survey was designed. The developed Work Stress Inventory (WSI), modified Professional Commitment Scale (PCS) and Organizational Commitment Scale (OCS) were used as measures. A total of 82.6% (n=404) of teachers in 14 junior nursing colleges in Taiwan anonymously completed the questionnaire. The subjects exhibited a medium-high level of work stress, organizational commitment and professional commitment. There was significant negative correlation between work stress and organizational commitment, and significant positive correlation between organizational commitment and professional commitment. The structural equation model showed that work stress directly affects organizational commitment (r=-0.47) and indirectly affects professional commitment, while organizational commitment directly affects professional commitment (r=0.58). The work stress of nursing educators in junior nursing colleges in Taiwan should be of concern because it plays an antecedent role in organizational commitment and professional commitment.
