背景：从管理的角度来看，有必要检查医院的最高管理层如何评估其组织中的患者安全文化。本研究旨在探讨《医院安全文化医院管理问卷》(HSOPS_M)与《医院员工安全文化问卷》(HSOPS_M)是否具有相同的心理测量学特性。在评估心理测量学特性时，我们进行了验证性因素分析(CFA)。结果：共有551名医学主任收回问卷。CFA的结果表明，全球数据符合令人满意的情况。局部拟合度指数显示出良好的收敛效度，但不能令人满意。结构效度分析表明，并不是所有的安全文化维度都很容易区分。结论：对HSOPS_M的心理测量学特性进行了分析，得出了较好的属性价值水平。尽管HSOPS-M中的一组维度需要进一步完善，但问卷涵盖了广泛的子维度，并提供了有关安全文化的重要信息。因此，HSOPS_M有资格从医院管理层的角度衡量安全文化，并可用于全国医院调查，以进行组织间比较。
Background: From a management perspective, it is necessary to examine how a hospital's top management assess the patient safety culture in their organisation. This study examines whether the Hospital Survey on Patient Safety Culture for hospital management (HSOPS_M) has the same psychometric properties as the HSOPS for hospital employees does.Methods: In 2008, a questionnaire survey including the HSOPS_M was conducted with 1,224 medical directors from German hospitals. When assessing the psychometric properties, we performed a confirmatory factor analysis (CFA). Additionally, we proved construct validity and internal consistency.Results: A total of 551 medical directors returned the questionnaire. The results of the CFA suggested a satisfactory global data fit. The indices of local fit indicated a good, but not satisfactory convergent validity. Analyses of construct validity indicated that not all safety culture dimensions were readily distinguishable. However, Cronbach's alpha indicated that the dimensions had an acceptable level of reliability.Conclusion: The analyses of the psychometric properties of the HSOPS_M resulted in reasonably good levels of property values. Although the set of dimensions within the HSOPS_M needs further scale refinement, the questionnaire covers a broad range of sub-dimensions and supplies important information on safety culture. The HSOPS_M, therefore, is eligible to measure safety culture from the hospital management's points of view and could be used in nationwide hospital surveys to make inter-organisational comparisons.
