Measurement model: Discriminant validity.

Nurses play a crucial role in the adoption and continued use of Electronic Health Records (EHRs), especially in developing countries. Existing literature scarcely addresses how personality traits and organisational support influence nurses’ decision to persist with EHR use in these regions. This study developed a model combining the Five-Factor Model (FFM) and the Unified Theory of Acceptance and Use of Technology (UTAUT) to explore the impact of personality traits and organisational support on nurses’ continuance intention to use EHR systems. Data were collected via a self-reported survey from 472 nurses across 10 public hospitals in Jordan and analyzed using a structural equation modeling approach (Smart PLS-SEM 4). The analysis revealed that personality traits, specifically Openness, Experience, and Conscientiousness, significantly influence nurses’ decisions to continue using EHR systems. Furthermore, organisational support, enhanced by Performance Expectancy and Facilitating Conditions, positively affected their ongoing commitment to EHR use. The findings underscore the importance of considering individual personality traits and providing robust organisational support in promoting sustained EHR usage among nurses. These insights are vital for healthcare organisations aiming to foster a conducive environment for EHR system adoption, thereby enhancing patient care outcomes.护理人员在电子健康档案（Electronic Health Records, EHRs）的采纳与持续使用中扮演着关键角色，在发展中国家这一作用尤为显著。现有文献鲜有探讨在这类地区，人格特质与组织支持如何影响护理人员持续使用EHR的决策。本研究构建了结合大五人格模型（Five-Factor Model, FFM）与技术接受与使用统一理论（Unified Theory of Acceptance and Use of Technology, UTAUT）的模型，以探究人格特质与组织支持对护理人员持续使用EHR系统的持续使用意愿的影响。本研究通过自我报告式问卷调查，从约旦10家公立医院的472名护理人员处收集数据，并采用结构方程模型（Smart PLS-SEM 4）开展分析。分析结果显示，人格特质中的开放性（Openness）、经验开放性（Experience）与尽责性（Conscientiousness）会显著影响护理人员持续使用EHR系统的决策。此外，在绩效期望与促成条件的加持下，组织支持对护理人员持续使用EHR的承诺产生了积极影响。本研究结果凸显了在推动护理人员持续使用EHR的过程中，兼顾个体人格特质与提供强有力的组织支持的重要性。这些研究结论对于旨在营造利于EHR系统采纳的良好环境、进而提升患者护理质量的医疗组织而言至关重要。
