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.

越南文版知识、态度、获取与信心评估问卷的信度与效度。

目的：为了有效地评估循证牙科（EBD）培训效果，精确和有效的评估工具是必不可少的。本研究旨在建构越南版的KACE问卷（知识、态度、获取与信心评估），并评估其信度与效度。方法：对原KACE问卷进行翻译后，进行面效度、内容效度和判别效度检验。计算Cronbach’s alpha和类内相关系数（ICC）来评估越南KACE问卷的内部一致性和信度。结果：30名讲师和280名牙科学生完成了KACE问卷。在讲师和牙科学生群体中，态度量表的Cronbach's alpha在0.90到0.97之间，获取证据量表的Cronbach's alpha在0.90到0.96之间，信心量表的Cronbach's alpha在0.83到0.93之间。知识量表的Cronbach's alpha值为0.55 ~ 0.79。总体ICC为0.861，表明测量结果稳定一致。结论：越南版的KACE问卷是评估越南牙科学生和从业人员EBD能力的可靠和有价值的工具。
