Abstract：
UNASSIGNED: Professionalism is a key quality that medical students should possess, but it is difficult to define and assess. Current assess-ment tools have room for improvement. This study aimed to design and validate a self-assessment tool to assess professionalism among medical students.
UNASSIGNED: A questionnaire was created based on 10 tenets of professionalism from the Charter on Medical Professionalism jointly published by the American Board of Internal Medicine Foundation, American College of Physicians Foundation and European Federation of Internal Medicine, along with input from Singapore guides. The self-administered questionnaire was administered to Year 2 to 5 students from Yong Loo Lin School of Medicine, National University of Singapore in a voluntary, anonymised manner in the academic year of 2019/2020. Construct validity and internal reliability were evaluated using Principal Component Analysis (PCA) and Cronbach\'s alpha, respectively.
UNASSIGNED: There was a total of 541 respondents. After removing incomplete responses, 504 responses were included. Following PCA, a 17-item questionnaire titled \"Medical Professionalism: A Self-assessment Tool\" (MPAST) with a 5-component solution was obtained. The 5 components were commit-ment to: (1) patient\'s best interest, (2) honesty and integrity, (3) professional competency, (4) patient safety and care, and (5) educational responsibilities. Their Cronbach\'s alpha value ranged from 0.540 to 0.714, with an overall Cronbach\'s alpha value of 0.777.
UNASSIGNED: MPAST is valid, reliable, practical, and is the first validated self-assessment tool to assess professional attributes and behaviours among medical students, to our knowledge.

摘要：
■专业素养是医学生应具备的关键素质,但是很难定义和评估。当前的评估工具还有改进的空间。本研究旨在设计和验证一种自我评估工具，以评估医学生的专业水平。
■根据美国内科医学委员会基金会联合出版的《医学专业主义宪章》中的10项专业原则创建了一份问卷，美国医师学会基金会和欧洲内科医学联合会，以及新加坡指南的输入。自编问卷发放给林永路医学院2至5年级学生,新加坡国立大学自愿参加，2019/2020学年的匿名方式。使用主成分分析(PCA)和Cronbachα评估结构效度和内部信度，分别。
■共有541名受访者。删除不完整的响应后，包括504个回答。在PCA之后，获得了一项17项问卷，标题为“医疗专业：自我评估工具”（MPAST），使用5组分溶液。这5个组成部分致力于：(1)患者的最大利益，(2)诚实正直,（3）专业能力，(4)患者安全和护理，（五）教育责任。他们的Cronbach的alpha值为0.540至0.714，Cronbach的整体alpha值为0.777。
■MPAST有效，可靠,实用,并且是第一个经过验证的自我评估工具，用于评估医学生的专业属性和行为，我们的知识。
