Abstract: Objective To develop the patient safety assessment scale and test its reliability and validity. Methods The scale was initially built through literature review，expert interviews and expert consultation method. A total of 351 nurses were selected to conduct pilot investigation. Item analysis，correlation analysis，exploratory factor analysis and Cronbach’s alpha were used to screen items. A total of 544 nurses were recruited to conduct formal investigation. The reliability of the scale was evaluated by consistency reliability analysis and split-half reliability analysis， and the validity was evaluated by exploratory factor analysis and confirmatory factor analysis. Results The scale was consisted of 7 dimensions and 54 items. Cronbach's alpha coefficient was 0.98，content validity index was 0.99，and accumulative contribution rate of each dimension was 63.28% to 78.26% . Confirmatory factor analysis showed the scale had good construct validity. Conclusion This scale has been proved reliable and valid and can be used for patient safety assessment.

摘要： 目的 编制患者安全评价量表，并进行信效度检验，为评估患者安全提供一个有效的测评工具。 方法 采用文献回顾、专家访谈和专家评议法，拟定初始量表。 选取351名护理人员进行预调查，量表条目的筛选采用项目区分度分析、相关性分析、探索性因素分析和内部一致性检验。 选取544名护理人员进行正式调查，量表信度评价采用内部一致性信度和折半信度，量表效度评价采用内容效度和结构效度。 结果 正式量表包括7个维度54个条目。 该量表Cronbanch‘s α系数为0.98；内容效度指标为0.99；各维度累积贡献率为63.28%～78.26%；验证性因素分析显示该量表具有较好的结构效度。 结论 该量表具有良好的信效度，可以用于护理人员对患者安全状况的评价。
