Abstract

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. SUMMARY STATEMENT: What is already known about this topic? To develop approaches to increase evidence‐based practice (EBP) competency and to improve attitudes and behaviour toward EBP; changes in these outcomes should be assessed via a valid and reliable tool. A Japanese version of such a tool is not available. The Evidence‐Based Practice Questionnaire (EBPQ) is a representative tool that measures factors influencing the uptake and implementation and has already been translated into many languages. What this paper adds? The EBPQ was translated into Japanese; the resultant Evidence‐Based Practice Questionnaire‐Japanese version (EBPQ‐J) comprises 18 items and 4 subscales, including practice, attitudes, and knowledge/skills related to research and practice, and has demonstrated moderate validity and reliability. For the test‐retest method, the reliability of practice and knowledge/skills was high, but that of attitude was low. Items about knowledge/skills regarding practice did not fit the original model well, as has been the case of EBPQ translated into other languages. The implications of this paper: The EBPQ‐J can comprehensively describe the current status of EBP and contribute to clarifying the necessary educational support for nurses. The EBPQ‐J can help compare EBP activity and competency between Japanese nurses and nurses in other countries. The EBPQ‐J scores could be used to indicate the outcomes of interventional studies regarding EBP.
