背景：在组织研究中强调了制定影响循证实践的实用和可靠措施的必要性。本研究的目的是评估希腊版实施领导力量表(ILS)的心理测量学特性。在实施循证实践时，ILS是衡量领导力的一种简单而有效的工具。对问卷的表面效度和内容效度进行了检验。然后，对在希腊一家私立医院工作的143名护士和助产士进行了测试，测试了ILS的心理测量学特性。验证性因素分析用于结构效度检验，皮尔逊系数用于收敛效度和判别效度检验，内部一致性分析用于信度检验。结果：希腊版ILS具有较好的面子效度和内容效度。CFA结果(x(2)=100。69(50)；CFI=0.93；GFI=0.83；RMSEA=0.06)证实了量表的四因素结构(主动性、知识性、支持性和坚持性)。内部一致性良好(总量表a=0.94，分量表a=0.85~0.91)。结论：希腊版ILS是衡量循证实践实施领导力的有效和可靠的工具。然而，建议在不同的样本和更专业的群体中对其心理测量学特性进行进一步的研究。
Background: The need for developing pragmatic and reliable measures that affect evidence-based practice has been highlighted in organizational studies. The aim of the current study is to evaluate the psychometric properties of the Greek version of Implementation Leadership Scale (ILS). ILS is a brief and effective tool for measuring leadership when implementing evidence based practices.Methods: The translation process followed World Health Organization guidelines. Face and content validity were examined. Then, the psychometric properties of ILS were tested with a sample of 143 nurses and midwifes working in a private Greek hospital. Confirmatory Factor Analyses for structural validity testing, Pearson coefficient for convergent and discriminant validity testing as well as internal consistency analysis for reliability testing were conducted. Quality of leadership scale from COPSOQ II and Organizational Climate Measure were used for assessing convergent and discriminant validity, respectively.Results: Greek version of ILS show good face and content validity. CFA results (x(2)=100. 69 (50); CFI=0.93; GFI=0.83; RMSEA=0.06) confirmed the four-factor structure of the scale (Proactive, Knowledgeable, Supportive and Perseverant leadership). The internal consistency was excellent (a=0.94 for total scale and between 0.85 and 0.91 for subscales). Analyses also revealed good convergent and discriminant validity.Conclusions: The findings suggest that the Greek Version of ILS is a valid and reliable tool for measuring leadership of evidence based practices implementation. However, further research for assessing its psychometric properties in various samples and more professional groups is suggested.
