背景：標準化病人測驗係以標準化病人模擬臨床情境的方式，瞭解受試者執行臨床檢查及處置能力的測驗方式。在本文中，我們就實施外科系實施標準化病人測驗之經驗加以整理報告。研究對象及方法：臺大醫院外科部於2005年舉辦兩次標準化病人測驗，受測對象為104位醫學系七年級實習醫學生。結果：受試者平均成績為84.7分，標準差為6.46分，與同組學生之傳統筆試成績相較（平均成績：84.2分，標準差：13.1分），兩者之平均值並無顯著差異（p=0.772），兩種成績亦欠缺線性相關關係（p=0.202），但標準化病人測驗成績之變異數明顯小於傳統筆試成績（p<0.01）。多數受測者認為標準化病人的扮演專業、測驗內容包含於平日所學中、考試難易適中以及考試環境布置符合臨床實境，惟近四成（39%）受試者認為測驗時間過短。結論：標準化病人測驗於國內為一種可行的測驗方式，以此種方式測驗所得之成績並不一定與傳統筆試成績有顯著相關。如果加以良好之設計，此種測驗方式將有助於反應醫學生的臨床能力，並導正醫學生的學習方向。

Background: The standardized patient test (SPY) is a tool used to measure the clinical ability of students by the simulation of clinical situations. In this paper, we reported our experience using standardized patients in surgical tests. Material and Methods: In 2005, we held two standardized patient tests in our department, and, in total, 104 interns took part in this examination. Results: The interns average grades for the SPY was (84.7+6.46), which was not significantly different from the scores they got from the purely written examination (84.2+13.1). However, there was no significant correlation between the scores from the SPY and the written test. Furthermore, the variance of the scores from the SPY was significantly lower than that from the written test. When asked to comment, most of the examinees thought: firstly, that the standardized patients worked well; secondly, that the content of the SPY included what they had encountered in daily clinical practice; thirdly, that the difficulty of the SPY was fair to the students and finally that the simulation of the clinical environment was appropriate. However, approximately 40% of the examinees complained of the limited time available to complete the SPY. Conclusions: SPY is feasible in Taiwan. If it is well designed, an SPY is able to reflect the medical student's clinical ability and guide their study attitudes.
