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.
