Abstract

Aim: To develop and test the validity and reliability of a Japanese version of the Evidence-Based Practice Questionnaire. Methods: The Evidence-Based Practice Questionnaire was translated into Japanese, and a back-translation was performed. In March 2016, the survey was conducted among 843 nurses in 2 university hospitals in Japan. After 2 weeks, the same questionnaire for test-retest reliability was distributed to 197 nurses. We evaluated construct validity by factor analysis: convergent, discriminant, criterion-based and known-group validity, and reliability (internal consistency via Cronbach' alpha and test-retest reliability). Results: A total of 533 (66%) of nurses who agreed to our study returned the completed questionnaire, and 108 nurses (55%) agreed to the test-retest. Factor analysis confirmed that the original model of the Evidence-Based Practices Questionnaire was not statistically appropriate for Japanese nurses. Therefore, the final version of the Japanese version adopted 18 items and 4 subscales including practice, attitudes, and knowledge/skills related to research and practice. In the final version, the validity and reliability were moderate (Cronbach alpha =.90). Conclusion: The Japanese version of the Evidence-Based Practices Questionnaire is a reliable and valid tool and can be used to assess evidence-based practice, attitudes, and research knowledge/skills in Japan.
