Improving patient safety and reducing occupational accidents are two of the main challenges in healthcare. Instruments to measure safety performance and occupational safety are rare. This study aimed to prepare and validate a German version of the adapted workplace health and safety instrument to assess the safety performance of healthcare professionals. Overall, 168 healthcare professionals participated in this explorative cross-sectional study. The instrument consists of 16 items related to safety performance in four dimensions. We calculated mean values and standard deviations for each individual item and those of the four dimensions of the instrument. We evaluated internal consistency and construct validity, explored the dimensionality of the instrument through exploratory factor analysis, and tested how our data fit with the original model with confirmatory factor analysis. Among the participants, 73.8% were nurses and nurses in training, with the majority of the sample being female (71.9%) and younger than 30 (52.5%). Cronbach's alpha for all four dimensions was >0.7. All items were loaded on factors according to the original theoretical model. Confirmatory factor analysis showed good model fit (normed χ²/df = 1.43 (≤2.5), root mean square error of approximation = 0.06 (≤0.07), goodness of fit index = 0.90 (>0.90), comparative fit index = 0.95 (≥0.90), and Tucker-Lewis index = 0.93 (>0.90). The German version of the instrument demonstrated acceptable properties and was a good fit to the original theoretical model, allowing measurement of healthcare professionals' safety knowledge, motivation, compliance, and participation.
提高患者安全和减少职业事故是医疗保健领域的两个主要挑战。衡量安全绩效和职业安全的工具很少。本研究旨在制备和验证经过改编的工作场所健康和安全工具的德语版本，以评估医疗保健专业人员的安全绩效。共有 168 名医疗保健专业人员参与了这项探索性横断面研究。该工具包含与四个维度的安全绩效相关的 16 个项目。我们计算了每个项目和工具四个维度的平均值和标准差。我们评估了内部一致性和结构有效性，通过探索性因素分析探讨了工具的维度，并通过验证性因素分析测试了我们的数据与原始模型的拟合程度。在参与者中，73.8%是护士和护士培训生，大多数样本是女性（71.9%），年龄小于 30 岁（52.5%）。所有四个维度的 Cronbach 的 alpha 值均大于 0.7。所有项目均根据原始理论模型加载到因子上。验证性因素分析显示模型拟合良好（归一化 χ²/df = 1.43（≤2.5），近似均方根误差 = 0.06（≤0.07），拟合优度指数 = 0.90（>0.90），比较拟合指数 = 0.95（≥0.90），和 Tucker-Lewis 指数 = 0.93（>0.90）。该工具的德语版本具有可接受的特性，与原始理论模型拟合良好，可测量医疗保健专业人员的安全知识、动机、合规性和参与度。
