Validity and reliability of Evidence-Based Practice Leadership Scale and Evidence-Based Work Environment Scale in Turkish

Abstract

Purpose: This study aims to evaluate the validity and reliability of the Evidence-Based Practice Leadership Scale (EBPLS) and Work Environment Scale (EBPWES) translated into Turkish so that they are used in nursing research.

Design and methods: This methodological study was conducted with nurses. Language and content validity, item analyses were used to test the validity and reliability of the scales.

Findings: The confirmatory factor analysis results demonstrate that t values of each item in both scales are significant (P < .05). All model and data fit indices are higher than the acceptable level. Thus, CFA has shown that the scales with model-data fit are valid.

Practice implications: The characteristics of nurse leaders and the suitability of the working environment are crucial for the maintenance of evidence-based practices. EBPLS and EBPWES will be effective and reliable tools in our country and an effective tool for contributing to the maintenance and development of evidence-based practices. The analyses indicate that the Turkish versions of the EBPLS and the EBPWES are acceptable, valid, and reliable for Turkish nurses.
