Irrational drug use has become a global problem threatening human health. As future health professionals, medical college students' medication literacy (ML) is critical. Their mastery of medication-related knowledge will directly affect public medication safety in the future.
The initial scale was developed through a literature review and was modified through expert consultation and student interviews to form the initial scale with 14 items. In 2020, a questionnaire survey was conducted among students in a medical college for item analysis, reliability test, validity test and other analyses.
The total Cronbach's α coefficient was 0.826 and split-half reliability was 0.852. The Cronbach's α coefficients for functional medication literacy, communicative medication literacy, and critical medication literacy were 0.901, 0.858, and 0.851, respectively. The item-level content validity index (I-CVI) ranged from 0.833 to 1.000 (≥ 0.78). Factor analysis of 14 items showed that KMO = 0. 852(> 0.7) and Bartlett's spherical test p < 0.001, indicating that the data are very suitable for factor analysis. Three principal axis factors were extracted by principal component analysis, and the total variance interpretation rate was 69.031% (> 40%). The confirmatory factor analysis identified a three-factor model and showed goodness of fit indices for the scale: The χ²/df = 2.623, The Goodness of Fit Index (GFI) = 0.905, The Comparative Fit Index (CFI) = 0.950, Normed Fit Index (NFI) = 0.922, Tucker-Lewis index (TLI) = 0.938, and The Root Mean Square Error of Approximation (RMSEA) = 0.078.
A new scale for evaluating the medication literacy of Chinese medical college students was preliminarily developed, demonstrating good reliability and validity. Itcan be used as a preliminary measurement tool for assessing medical students' medication literacy. However, due to the limitations of this study, the practical application of the scale needs to be further examined in a larger sample and should be refined in future studies.
不合理用药已成为威胁人类健康的全球性问题。作为未来的医疗专业人员，医学生的用药素养（ML）至关重要。他们对药物相关知识的掌握程度将直接影响未来公众的用药安全。
初始量表通过文献回顾制定，并通过专家咨询和学生访谈进行修改，形成了包含 14 个项目的初始量表。2020 年，对一所医学院的学生进行了问卷调查，进行项目分析、信度测试、效度测试等分析。
总量表 Cronbach's α 系数为 0.826，分半信度为 0.852。功能性用药素养、沟通性用药素养和批判性用药素养的 Cronbach's α 系数分别为 0.901、0.858 和 0.851。条目水平内容效度指数（I-CVI）范围为 0.833 至 1.000（≥0.78）。14 个条目的因子分析显示，KMO=0.852（>0.7），Bartlett 球形检验 p<0.001，表明数据非常适合因子分析。主成分分析提取 3 个主轴因子，总方差解释率为 69.031%（>40%）。验证性因子分析确定了一个三因素模型，表明该量表具有良好的拟合度指标：χ²/df=2.623，拟合优度指数（GFI）=0.905，比较拟合指数（CFI）=0.950，归一拟合指数（NFI）=0.922，Tucker-Lewis 指数（TLI）=0.938，近似均方根误差（RMSEA）=0.078。
初步开发了一种用于评估中国医学生用药素养的新量表，具有良好的信度和效度。可作为评估医学生用药素养的初步测量工具。但由于本研究的局限性，该量表的实际应用需要在更大的样本中进一步检验，并在未来的研究中进行细化。
