Psychometric Testing of the Evidence-Based Practice Nursing Leadership Scale and the Work Environment Scale After Cross-Cultural Adaptation in Mainland China.

Implementation and sustainability of the evidence-based practice (EBP) approach within systems of health-care delivery require leadership and organizational support, yet few instruments have been developed specifically in Mainland China. The purpose of this study was to adapt the EBP Nursing Leadership Scale and the EBP Work Environment Scale to Mainland China's cultural context and to evaluate the psychometric properties of the newly adapted Chinese version. A pilot study was conducted in Mainland China with 25 clinical nurses. A subsequent validation study was conducted with 419 nurses from Mainland China. A content validity index of .985 and .982 was achieved. The split-half coefficient was .890 for the EBP Nursing Leadership Scale and .892 for the EBP Work Environment Scale. Test-retest reliability was .871 and .855, respectively. Principal component analysis resulted in a one-factor structure explaining 62.069% of the total variance for the EBP Nursing Leadership Scale and 62.242% of the total variance for the EBP Work Environment Scale. Both of the newly cross-culturally adapted scales possess adequate internal consistency and test-retest reliability and validity and therefore may be utilized in health-care environments to assess leadership and organizational support for EBP in Mainland China.
