Abstract

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.
