本研究以某醫學為419名低年學生實醫Q分類自我概念評量，並針對評量工具及各項自我概念指標進行相關研究。 結果發現，醫學院低年級學生在主觀我方面，傾向以坦白誠實、幽默樂觀、勤奮努力、寬宏大量來描述自己，而比較不認為自己是口才好、學識豐富、情緒穩定、動作敏捷。理想我方面，則希望自已是學識豐富、聰明能幹、健康強壯、幽默樂觀、人緣好，而比較不在乎自己是否動作敏捷、熱心服務、英俊秀麗。投射我方面，傾向認為別人對他們的印象是幽默樂觀、坦白誠實、人緣好、健康強壯、熱心服務，而較不認為別人對他們的印象是口才好、動作敏捷、情緒穩定。 在三個自我概念層面之間，主觀我和投射我較為相近，理想我則與前二者差異很大。醫學院低年級學生在主觀我與理想我之間的負向差距最大的來源在於自覺學識不夠豐富、口才不夠好、不夠堅毅有�琚B情緒不夠穩定等、男女的Q分類結果相當類似；以選擇前五張卡片或第一張卡片來分析，所得到的結果亦無多大差異。 在相關研究方面，以Q分類測量自我概念，所得結果與人格測驗之得分有適度之關連，例如：主觀我情緒穩定一項的分配值與基氏人格測驗上的抑鬱性、感情變異性、自卑感、神經質等分量尺及情緒不穩定的總分呈負相關。理想我與投射我的Q分結果以及整體自我概念指標與自我接受指標I與人格測驗的得分亦出現不少有意義的關聯。研究者並針對Q分類工具之特性及研究，提出討論與建議。

　　　　　A Q-sort technique was administered to assess the self concept of 419 students in a medical college. The results indicated that, in choosing and sorting 15 personality traits, college students tended to describe themselves more as frank , humorous-optimistic, diligent, and open-hearted than as persuasive, learned, emotionally stable, and agile. In describing their ideal self, students wanted more to be learned, intelli-gent-competent, healthy, humorous-optimistic, and popular than to be agile, enthu-siastic, and handsome.In describing the self which they feel they project to others, students tended to figure that others see them more as humourous-optimistic, frank, popular, healthy, and enthusiastic than as persuasive, agile, and emotionally stable. Among the three levels of self concept, the subjective self and the projective self were similar to each other but were actually quite different from the ideal self. The main source of difference between the subjective self and the ideal self came from the sorting of the qualities of learnedness, persuasiveness, diligence, and emotion stability. The Q-distributions of male and female students were quite similar to each other. It also made little difference whether the first five cards or the first card was chosen for analysis. The relation between scores of the Q-sort and the Guilford Personality Inventory demonstrated the concurrent validity of the Q-sort technique. For example:the weighted score of emotional stability from the Q-sort was significantly negatively correlated with the the scales of depression. Cyclic tendency, feelings of inferiority, and nervousness found in the inventory. The validity of the total self concept index and self acceptance index I were also supported but this was not the case for idexes II and III. The special characteristics of the Q-sort technique and its utility in the field of counseling and guidance were also examined.
