Abstract: OBJECTIVE: To effectively evaluate evidence-based dentistry (EBD) training outcomes, precise and validated assessment tools are essential. This study aimed to construct a Vietnamese version of the KACE questionnaire (Knowledge, Attitudes, Access, and Confidence Evaluation) and to assess its reliability and validity. METHODS: After translating the original KACE questionnaire, we conducted tests for face validity, content validity, and discriminant validity test. Cronbach's alpha and intraclass correlation coefficients (ICC) were calculated to evaluate the internal consistency and reliability of the Vietnamese KACE questionnaire. RESULTS: Thirty lecturers and 280 dental students completed the KACE questionnaire. Cronbach's alpha for the Attitude scale ranged from 0.90 to 0.97, for the Accessing Evidence scale from 0.90 to 0.96, and for the Confidence scale ranged from 0.83 to 0.93 across lecturers and dental student groups. The Knowledge scale had Cronbach's alpha from 0.55 to 0.79. The overall ICC of 0.861 indicated that the measurement is stable and consistent. CONCLUSION: The Vietnamese adaptation of the KACE questionnaire is a reliable and valuable tool for assessing EBD competencies among Vietnamese dental students and practitioners.
