To translate and revise the Medication Literacy Assessment in English (MedLitRxSE-English) and evaluate its validity and reliability. Methods: We introduced MedLitRxSE-English from abroad. According to the principles of Brislin and culture adjustment, we revised it as a Chinese edition. Using random sampling method, from Oct, 2014 to Jan, 2015, 461 non-hospitalized patients from the outpatient departments of the top three hospitals in Changsha city were investigated. The reliability and validity of the scale was tested. Results: The test-retest reliability of the Chinese version for medication literacy scale was 0.885; the split reliability was 0.840; K-R was 0.820; the correlations between the assessment of medication literacy and the corresponding items were 0.427-0.587; the confirmatory factor analysis revealed overall good fit. Root mean square error of approximation (RMSEA), χ2/df, goodness of fit index (GFI) and comparative fit index (CFI) was 0.08, 3.06, 0.91 and 0.94, respectively. Conclusion: The Chinese version for the assessment of medication literacy is in good reliability and validity, and it can be used to evaluate the medication literacy in our country.
目的：编译中文版药物素养评估量表，并对其进行信效度评价。方法：引进MedLitRxSE-English量表，按照Brislin问卷翻译-回译原则及文化调试，最终形成了一个包含14个条目的单维度药物素养评估量表。在2014年10月至2015年1月，采用单纯随机抽样的方式，随机抽取了461名在长沙市省级三甲医院门诊就诊的非住院患者进行问卷调查，并对其信效度进行分析。结果：中文版药物素养评估量表的重测信度为0.885；分半信度为0.840；库德-理查逊公式(Kuder Richardson formula 20，K-R20)计算K-R值为0.820；各条目与量表总分的相关系数在0.427~0.587之间；单因子结构方程模型拟合良好，近似误差均方根(root mean square error of approximation，RMSEA)为0.08，χ2/df=3.06，拟合优度指数(goodness of fit index，GFI)为0.91，比较拟合指数(comparative fit index，CFI)为0.944。结论：中文版药物素养评估量表的信效度良好，可作为我国对药物素养评价的工具。.
