cross-cultural adaptation and psychometric validation of the vietnamese version of the evidence-based practice competency questionnaire for registered nurses (ebp-coq prof©)

Background & aim: establishing strategies to enhance evidence-based practice (ebp) requires a reliable instrument for assessing ebp competency. this study focused on translating and validating the evidence-based practice competency questionnaire for registered nurses (ebp-coq prof©) in the vietnamese context. methods & materials: through a methodological approach, this study performed cross-cultural adaptation and psychometric validation. the study involved 372 nurses selected through convenience sampling. content validity was established using the content validity index for items (i-cvi) and the content validity index for scales (s-cvi). construct validity was assessed via exploratory (efa) and confirmatory factor analysis (cfa). reliability was determined using cronbach's alpha and the intra-class correlation coefficient (icc). criterion validity was examined by comparing ebp-coq prof© competency between nurses with and without prior ebp education. results: the vietnamese version of ebp-coq prof© maintained consistency with the original version following cross-cultural adaptation. content validity was confirmed with i-cvi> 0.78 and s-cvi/ave= 0.97. efa and cfa revealed consistent components with the original version: attitude (8 items), knowledge (11 items), skills (6 items), and utilization (10 items). cronbach's alpha values were high: attitudes (0.965), knowledge (0.962), skills (0.909), and utilization (0.926). icc values were also significant: attitudes (0.754), knowledge (0.895), skills (0.823), and utilization (0.966). nurses with prior ebp education demonstrated higher ebp-coq prof© competency. conclusion: the translated and validated ebp-coq prof© provides a robust tool for assessing ebp competency among vietnamese nurses. its reliability, validity, and sensitivity to educational effects underscore its potential for promoting ebp in nursing.
