目标展示用于测试患者安全调查工具的测量等效性的统计分析。本研究中检查的调查工具是药物管理错误报告调查。方法调查被张贴到德克萨斯州注册护士的随机样本中，有 435 名护士完成了调查。调查包含有关各种错误报告问题的问题，包括 16 项药物管理错误报告量表。护士被分为两个样本之一——校准样本和保留样本——以确保结果的可重复性。在每个样本中，根据护士在工作中的任期创建了两组。结果对具有不同经验水平的校准和保留样本的护士进行了多组验证性因素分析。对于每个样本，估计基线模型，其中模型参数允许在护理组之间变化，并与更严格的模型进行比较。结果为药物管理错误报告系统的因素结构提供了支持，但在不同护理组之间的测量等效性方面产生了不同的结果。结论本研究解释了如何检查调查工具的测量等效性，并证明药物管理错误报告量表在不同经验水平的护士之间可能并不相同。
ObjectivesTo demonstrate a statistical analysis for testing the measurement equivalence of a patient safety survey instrument. The survey instrument examined in the present study is the Medication Administration Error Reporting Survey.MethodsSurveys were posted to a random sample of registered nurses in the State of Texas, with 435 nurses completing the survey. The surveys contained questions about various error reporting issues, including the 16-item, Medication Administration Error Reporting scale. Nurses were divided into one of two samples—calibration and holdout—to ensure replicability of the results. Within each sample, two groups were created based on nurse tenure on the job.ResultsMultiple Group Confirmatory Factor Analysis was conducted across nurses with varying levels of experience for the calibration and holdout samples. For each sample, a baseline model was estimated, where model parameters were allowed to vary across the nursing groups, and compared with more restrictive models. The results provided support for the factor structure of the Medication Administration Error Reporting System but yielded mixed results concerning the equivalence of the measure across nursing groups.ConclusionsThe present study provides an explanation of how to examine the measurement equivalence of survey instruments and demonstrated that the Medication Administration Error Reporting scale might not be equivalent across nurses who differ with respect to experience levels.
