Abstract

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 (x2 = 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.
