目的 开发基层医疗机构用药信息透明度测量量表.方法 通过查阅文献和咨询专家确定测量维度和条目.使用量表在东、中、西部共调查100家基层医疗机构.采用相关系数法、克朗巴赫系数法、因子分析法对条目进行筛选,得到正式量表.采用克朗巴赫系数和因子分析法评价量表的信度和效度.结果 量表包含服务流程公示、药事管理组织与制度公示、患者告知和健康教育、药品目录公示、患者费用负担公示,合理用药情况等维度.正式量表克朗巴赫系数为0.844,有较好的信度;因子分析KMO值为0.801,累计解释方差89.69%,条目在5个公因子上的分布与维度设置完全吻合,结构效度较好.结论 量表制作过程科学严谨,能可靠和有效地评价基层医疗机构用药信息透明度.%Objective To develop transparency measurement scale on medicine use information in primary health care facilities. Methods The dimensions and items of scale were determined through literature review and expert consultation. The scale was used to investigate 100 primary health care facilities in eastern, central and western regions. Correlation coefficient analysis, Cronbach's coefficient, and exploratory factor analysis were used to select items. Five dimensions and 20 items were selected for the final scale. Cronbach's coefficient was used to evaluate the reliability of the formal scale. Factor analysis was used for construct validity evaluation. Results Dimensions were measured, including service processes, organization and regulation for pharmacy administration, patients informing and education, medicine catalogue, and the economic burden of patients. The scale had good reliability since overall Cronbach coefficient was 0. 844. Factor analysis extracted five common factors, total explaining 89. 69% of the cumulative variance, and the item distribution in five common factors was completely consistent with formal scale, indicating good construct validity. Conclusion This scale had good reliability and validity as a measurement tool to evaluate the transparency level of primary health care facilities in China.
