Evidence-based medicine is defined as searching for medical information, reviewing and comparing it to each patient's situation, and then judging the optimal decision. We aimed to measure the psychometric properties of the Evidence-Based Performance Profile (EBP) Questionnaire among the students of health-related fields at Shiraz University of Medical Sciences.
This cross-sectional study was conducted in 2021. The EBP2 questionnaire, which includes 74 five-Likert-scale items, was translated into the Persian language using the forward-backward translation method. A panel of five experts approved the face, content, and structural validity of the questionnaire. The Cronbach's alpha and McDonald's Omega coefficients were utilized to assess the questionnaire's internal consistency. Furthermore, both confirmatory and exploratory factor analyses were used to assess the questionnaire's construct validity. SPSS software version 25 and LISREL software version 8.8 were used for statistical analysis.
Overall, 339 students participated in this study. The cultural adaptability, linguistic equivalence, and content validity of the Persian version of the EBP questionnaire were approved by a five-member team of medical experts. In addition, the results showed excellent internal consistency of the Persian version of the EBP questionnaire (Cronbach's alpha = 0.962, McDonald's Omega (ML) = 0.963). Moreover, all domains had acceptable reliability (> 0.7), except the Practice domain which had a marginally acceptable Cronbach's alpha coefficient equal to 0.686. Exploratory factor analysis discovered six domains for the questionnaire. Moreover, the confirmatory factor analysis demonstrated that all indices except the comparative fit index (CFI) and adjusted goodness of fit (AGFI) confirmed the validity of the EBP questionnaire.
The study's findings indicate that the Persian translated of the EBP2 questionnaire exhibited satisfactory validity and reliability for assessing students' evidence-based performance in health-related fields.
循证医学被定义为搜索医学信息、对其进行审查并与每位患者的情况进行比较，然后判断最佳决策。我们旨在衡量 Shiraz 医科大学健康相关领域学生的循证表现概况（EBP）问卷的心理测量学特性。
这是一项 2021 年进行的横断面研究。EBP2 问卷包含 74 个五分制李克特量表项目，采用正向-反向翻译法翻译成波斯语。由五名专家组成的小组对问卷的表面、内容和结构有效性进行了评估。问卷的内部一致性采用克朗巴赫α和麦克唐纳ω系数进行评估。此外，还采用验证性和探索性因子分析来评估问卷的结构有效性。统计分析采用 SPSS 软件 25 版和 LISREL 软件 8.8 版。
共有 339 名学生参与了这项研究。一个由五名医学专家组成的小组批准了 EBP 问卷波斯语版本的文化适应性、语言等效性和内容有效性。此外，研究结果表明 EBP 问卷波斯语版本具有极好的内部一致性（克朗巴赫α=0.962，麦克唐纳ω（ML）=0.963）。此外，除实践领域的克朗巴赫α系数略可接受（等于 0.686）外，所有领域的可靠性均较高（>0.7）。探索性因子分析发现问卷有六个领域。此外，验证性因子分析表明，除比较拟合指数（CFI）和调整拟合优度（AGFI）外，所有指数均证实了 EBP 问卷的有效性。
研究结果表明，EBP2 问卷的波斯语翻译版在评估健康相关领域学生的循证表现方面具有良好的有效性和可靠性。
