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.
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.
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.
The Vietnamese adaptation of the KACE questionnaire is a reliable and valuable tool for assessing EBD competencies among Vietnamese dental students and practitioners.
为有效评估循证牙科（EBD）培训成果，精确且经过验证的评估工具至关重要。本研究旨在构建越南语版的KACE问卷（知识、态度、获取途径和信心评估）并评估其信效度。
翻译原始KACE问卷后，我们进行了表面效度、内容效度和区分效度测试。计算克朗巴哈系数（Cronbach's alpha）和组内相关系数（ICC）以评估越南语KACE问卷的内部一致性和信度。
30名讲师和280名牙科学生完成了KACE问卷。在讲师和牙科学生组中，态度量表的克朗巴哈系数在0.90至0.97之间，获取证据量表在0.90至0.96之间，信心量表在0.83至0.93之间。知识量表的克朗巴哈系数在0.55至0.79之间。总体ICC为0.861，表明测量稳定且一致。
越南语版的KACE问卷是评估越南牙科学生和从业者EBD能力的可靠且有价值的工具。
