中文版护理院患者安全文化测评量表的信度与效度分析
Analysis of reliability and validity of Chinese version of Nursing Home Survey on Patient Safety Culture

目的 译制中文版护理院患者安全文化测评量表并对其信度和效度进行初步验证。方法 对护理院患者安全文化测评量表（NHSOPSC）进行跨文化调适，形成中文版NHSOPSC量表，对6家护理院的322名工作人员进行问卷调查，通过专家论证、因子分析及计算信度系数对结果进行信度、效度检验。结果 中文版NHSOPSC量表保留23个条目，探索性因子分析提取出6个公因子，累积贡献率为65.28%，各条目的因子载荷范围为0.451～0.892。中文版NHSOPSC量表总的内部一致性系数(Cronbachs α)为0.884，各维度的Cronbachs α系数分别为0.841、0.804、0.737、0.757、0.866、0.815。总量表的重测信度为0.904，各维度的重测信度分别为0.913、0.786、0.963、0.895、0.951、0.709，重测关联有统计学意义(P<0.001)。结论 中文版NHSOPSC量表具有良好的信度与效度，可以作为测评我国护理院患者安全文化的有效工具。
： Objective To translate the Nursing Home Survey on Patient Safety Culture (NHSOPSC) into Chinese and verify the reliability and validity of the Chinese version of NHSOPSC. Methods The NHSOPSC was translated and adjusted according to Chinese culture. Three hundred and twenty-two personnel in 6 nursing homes were surveyed by questionnaire. The reliability and validity of the Chinese version of NHSOPSC were verified by expert opinion, factor analysis, and calculation of reliability coefficients. Results The Chinese version of NHSOPSC consisted of 23 items. The exploratory factor analysis extracted six common factors, which could explain 65.28% of the total variance and the factor loading of each item ranged from 0.451 to 0.892. The Cronbachs α of the total scale was 0.884 and the Cronbachs α values of subscales were 0.841, 0.804, 0.737, 0.757, 0.866, and 0.815 respectively. The test-retest reliability of the total scale was 0.904 and the test-retest reliability values of subscales were 0.913, 0.786, 0.963, 0.895, 0.951, and 0.709， respectively. The test-retest correlation was statistically significant (P<0.001). Conclusion The Chinese version of NHSOPSC is reliable and valid and can be used as an effective tool for assessing the patient safety culture in Chinese nursing homes
