背　景 批判性思考能力是護理臨床實務重要技能，增進護理人員批判性思考能力是增進問題解決、決策能力和照護品質管道之一，而選用適當的工具，檢測臨床護理人員的批判思考能力與意向，可做為人力資源管理者對資源的內涵與素質，培育與分配應用的參考指標。
目　的 本研究目的為探討某醫學中心不同級階護理人員之批判性思考能力及意向。
方　法 本研究為調查性研究設計，採分層隨機取樣，以某醫學中心N1至N4四種級階之護理人員為研究對象，研究工具為批判性思考能力及意念量表，研究工具採專家效度，CVI值.93，信度Cronbach’s α值為 .85，資料以SPSS 12.0 統計軟體分析。
結　果 研究顯示，臨床護理人員在批判性思考五項次能力中以詮釋能力最佳，推論能力最差；批判性思考意念方面以反省思考性意念最佳，追根究底性意念較差；護理人員的年齡、工作年資及其他醫院經驗和批判性思考能力相關（p < .05）；年齡、工作年資及級階則與批判性思考意念有關；臨床級階N4護理人員具較佳的批判性思考能力與意念；且批判性思考能力及其意向有正相關；其他醫院經驗及工作年資可預測護理人員批判思考能力之解釋量為29.3%，臨床級階及年齡可預測批判思考意念27.9%。
結　論 護理人員在工作經驗、年資、進階制度下，對批判性思考能力與意念有正向的影響，亦有相當的預測性解釋量。另本研究針對臨床護理人員設計之批判性思考能力測量工具，亦可提供未來研究者繼續檢驗與修訂。

Background: Critical thinking is essential in nursing practice.
Promoting critical thinking competence in clinical nurses is an important way to improve problem solving and decision-making competence to further improve the quality of patient care.
However, using an adequate tool to test nurses’ critical think-ing competence and disposition may provide the reference criteria for clinical nurse characterization, training planning, and resource allocation for human resource management.
Purpose: The purpose of this study was to measure the critical thinking competence and critical thinking disposition of clinical nurses as well as to explore the related factors of critical thinking competence.
Methods: Clinical nurses from four different clinical ladders selected from one medical center were stratified randomly.
All qualified subjects who submitted valid questionnaires were included in the study. A Taiwan version of the modified WatsonYGlaser Critical Thinking Appraisal and Critical Thinking Disposition Inventory was developed to measure the critical thinking competence and critical thinking disposition of clinical nurses. Validity was evaluated using the professional content test (content validity index = .93). Reliability was assessed with a Cronbach’s alpha coefficient of .85. Data were ana-
lyzed using the SPSS for Windows (Version 12.0; SPSS Inc., Chicago, IL).
Results: Results showed that competence of interpretation was the highest critical thinking competence factor. Inference was the lowest, and reflective thinking as a critical thinking dis-position was more positive. In addition, age, years of nursing experience, and experiences in other hospitals significantly in- fluenced critical thinking competence (p G .05). Factors of age,years of experience, and nurses clinical ladder were shown to affect critical thinking disposition scores. Clinical ladder N4 nurses had the highest scores in both competence and dis- position. A significant relationship was found between critical thinking competence and disposition scores, with 29.3% of the variance in critical thinking competence potentially explained by
total years of nurse hospital experience. Clinical ladder and age were predictive factors for critical thinking disposition. Common-ality was 27.9%.
Conclusions and Implications for Practice: Nursing expe-rience and clinical ladders positively affect critical thinking competence and disposition. Issues of critical thinking com-petence increasingly need to be measured. Therefore, appro-priate tools for nursing professions should be further developed and explored for specific areas of practice.
