Evidence-based practice (EBP) improves the quality of healthcare services and enhances patient safety. However, in Greece, the adoption of EBP remains modest, while validated assessment tools in the Greek language for measuring EBP among nurses are limited. The purpose of the study was to translate, culturally adapt, and psychometrically validate the Nursing Evidence-Based Practice Survey and Evidence-Based Practice Self-Efficacy Scale (EBP SES) tools into Greek.
The study sample comprised 222 registered nurses, including both clinical nurses and school-based nurses, through convenience sampling. Reliability analyses (Cronbach's α) and confirmatory factor analysis (CFA) were conducted to investigate internal consistency and structural validity.
The instruments showed high reliability (Cronbach's α = 0.78-0.96). The mean value of the Nursing Evidence-Based Practice Survey was 3.88 (standard deviation [SD] = 0.66), and the EBP SES was 73.4 (SD = 14.0), which reflects an overall favorable perception of EBP engagement. In CFA, the five-factor model of the Nursing EBP Survey showed fit indices: Goodness of Fit Index (GFI) = 0.960, Standardized Root Mean Square Residual (SRMR) = 0.041, Comparative Fit Index (CFI) = 0.899, Tucker-Lewis Index (TLI) = 0.885, and χ²/df = 4.1, while the single-factor model of the SES showed GFI = 0.980, SRMR = 0.056, CFI = 0.930, TLI = 0.913, and χ²/df = 3.4, indicating a good fit to the data.
The Greek versions of the instruments demonstrated robust psychometric properties, confirming their reliability and validity for use in the local nursing context. Based on the observed deficits, particularly in domains related to data collection and evidence appraisal, the findings underscore the necessity of implementing structured training programs, integrating EBP content into undergraduate and postgraduate nursing curricula, and developing continuous professional development (CPD) initiatives focused on enhancing evidence-based decision-making competencies.
循证实践（EBP）可提高医疗服务质量并增强患者安全。然而，在希腊，EBP的采用情况仍不乐观，而且用于评估希腊护士EBP水平的经过验证的评估工具有限。本研究的目的是将《护理循证实践调查问卷》和《循证实践自我效能量表》（EBP SES）工具翻译成希腊语，进行文化调适，并对其进行心理测量学验证。
通过便利抽样，研究样本包括222名注册护士，其中既有临床护士也有学校护士。进行可靠性分析（Cronbach's α）和验证性因素分析（CFA）以调查内部一致性和结构效度。
这些工具显示出高可靠性（Cronbach's α = 0.78 - 0.96）。《护理循证实践调查问卷》的平均值为3.88（标准差[SD] = 0.66），EBP SES为73.4（SD = 14.0），这反映出对EBP参与度的总体积极看法。在CFA中，《护理EBP调查问卷》的五因素模型显示拟合指数：拟合优度指数（GFI） = 0.960，标准化根均方残差（SRMR） = 0.041，比较拟合指数（CFI） = 0.899，塔克 - 刘易斯指数（TLI） = 0.885，χ²/df = 4.1，而SES的单因素模型显示GFI = 0.980，SRMR = 0.056，CFI = 0.930，TLI = 0.913，χ²/df = 3.4，表明与数据拟合良好。
这些工具的希腊语版本显示出强大的心理测量学特性，证实了它们在当地护理环境中使用的可靠性和有效性。基于观察到的不足，特别是在与数据收集和证据评估相关的领域，研究结果强调了实施结构化培训计划、将EBP内容纳入本科和研究生护理课程以及开展专注于提高循证决策能力的持续专业发展（CPD）举措的必要性。
