目的编制从医院整体层面测量、符合我国文化特色和医院实际情况的的患者安全文化测评量表,并检验其信效度,确保量表科学可行。方法通过文献法和专家咨询法形成量表初稿。使用量表初稿对四川省4家的412名医护人员、管理人员进行调查,采用相关分析、信度分析、因子分析统计方法对量表的信度与效度进行分析。结果患者安全文化测评正式量表包括共31个条目,分为6个因子、方差累计贡献率62.19%。6个因子分别为医院氛围及沟通、直接领导重视与支持、医院政策支持、负性事件的认识与处理、科室成员相互帮助、负性事件报告。整个量表的Cronbach’sα系数为0.909,各因子的α系数均大于0.79。量表折半信度系数为0.952,除因子四(折半系数为0.783)外,其他各因子的折半系数均大于0.8。结论量表具有较好的信度和效度,可以在医院中广泛使用。
Objective To prepare a patient safety culture evaluation scale measured from the overall hospital level, in line with the cultural characteristics of our country and the actual conditions of the hospital, and test its reliability and validity to ensure that the scale is scientific and feasible. Methods The first draft of the scale was formed through literature method and expert consultation. The first draft of the questionnaire was used to investigate 412 health care workers and managers in four hospitals in Sichuan Province. The reliability and validity of the questionnaire were analyzed by correlation analysis, reliability analysis and factor analysis. Results The official scale of patient safety culture evaluation consisted of 31 items, divided into 6 factors and the cumulative contribution rate of variance was 62.19%. The six factors were the hospital atmosphere and communication, direct leadership attention and support, hospital policy support, understanding and handling of negative events, mutual assistance of department members, and reporting of negative events. The Cronbach’s alpha coefficient of the entire scale was 0.909, and the alpha coefficients of each factor were greater than 0.79. The half-value reliability coefficient of the scale was 0.952. Except the factor four (the half-coefficient was 0.783), the other half factors were all greater than 0.8. Conclusion The scale has good reliability and validity and can be widely used in hospitals.
