Psychometric Properties of the Chinese Version of the Evidence-Based Practice Questionnaire for Nurses

Abstract

Background and PurposeThe Evidence-Based Practice Questionnaire (EBPQ-English) has been used in various populations. However, it has not been validated in the Chinese nursing population. This study aimed to translate EBPQ-English into Chinese and evaluate its psychometric properties.MethodsThe Brislin translation procedure was used to maintain the conceptual equivalence. The validity and reliability of EBPQ-Chinese were investigated using exploratory factor analysis and Cronbach's α with 810 nurses from nine tertiary hospitals in Southern China.ResultsPrinciple axis factoring and oblimin rotation yielded three factors with 22 items, including Knowledge and Skills (k = 14; α = 0.94), Attitudes (k = 3; α = 0.83), and Practice (k = 5; α = 0.86), which explained 57.03% of the total variance.ConclusionsEvidence supports the validity and reliability of a three-factor 22-item EBPQ-Chinese.
