The present study aimed to investigate the possible alternative factorial structure of the patient safety culture model in Iran.
This study was performed based on data collected by Hospital Survey on Patient Safety Culture (HSOPSC) questionnaire from 420 staff in four hospitals. Internal consistency reliability and construct validity were evaluated by Cronbach's alpha and correlation analysis. Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used to investigate the possible alternative factorial structure, examine and confirm the obtained structure, alternatively. Kaiser-Meyer-Olkin measure and Bartlett test were calculated to determine the factor ability of sample and fit of the factor analysis, alternatively. SPSS and AMOS version 25 were used.
EFA identified 12 dimensions which one dimension has been also created from a new question. Distribution of items in all dimensions differed from the original HSOPSC questionnaire except two dimensions. The obtained structure was a proportional model. The calculation of Cronbach's alpha (∝ = .8) showed that, the internal consistency reliability was appropriate for all items in the questionnaire. Also, construct validity was acceptable for all factors.
The structure of the dimensions obtained in this study was not consistent with the structure of the original HSOPSC model.
Provide a model for assessing patient safety culture with relative stability with respect to the native culture of the region. Good content and construct validity. Differences in the distribution of items in dimensions. Formation of new dimensions. Performing a psychometric analysis of the instrument using EFA, CFA and SEM to examine the disagreement on the validity, reliability and dimensions of patient safety culture in previous studies in Iran. Numerous discrepancies in item wording comply with the approach advocated by the translation guideline for AHRQ survey on patient safety.
本研究旨在探讨伊朗患者安全文化模型可能的替代因子结构。
本研究基于从四家医院的 420 名员工收集的医院患者安全文化调查(HSOPSC)问卷数据进行。通过 Cronbach's alpha 和相关分析评估内部一致性信度和构念效度。采用探索性因子分析(EFA)、验证性因子分析(CFA)和结构方程模型(SEM)来研究可能的替代因子结构,依次检验和确认所获得的结构。Kaiser-Meyer-Olkin 度量和 Bartlett 检验用于确定样本的因子能力和因子分析的拟合度,依次进行。使用 SPSS 和 AMOS 版本 25。
EFA 确定了 12 个维度,其中一个维度是从一个新问题中创建的。除了两个维度外,所有维度的项目分布都与原始 HSOPSC 问卷不同。所得到的结构是比例模型。Cronbach's alpha(∝=0.8)的计算表明,问卷中所有项目的内部一致性信度都适当。此外,所有因素的构念效度都是可以接受的。
本研究中获得的维度结构与原始 HSOPSC 模型的结构不一致。
提供一个与该地区本土文化具有相对稳定性的患者安全文化评估模型。具有良好的内容和构念效度。维度中项目分布的差异。新维度的形成。使用 EFA、CFA 和 SEM 对工具进行心理计量学分析,以检查伊朗之前研究中在患者安全文化的有效性、可靠性和维度上的分歧。项目措辞的许多差异符合 AHRQ 患者安全调查翻译指南所倡导的方法。
