Objectives. There is no existing Vietnamese diabetes knowledge questionnaire. This impedes assessment of patient knowledge that will be helpful in providing effective diabetes intervention. We aimed to validate the Vietnamese-translated Diabetes Knowledge Questionnaire (DKQ).

Methodology. Translation and adaptation strictly followed the guidelines of Beaton et al. Internal consistency was assessed by Cronbach’s alpha coefficient, test-retest reliability was assessed by Fleiss’ Kappa coefficient, and validity value was determined among type 2 diabetes patients in a general hospital.

Results. The Vietnamese version of the DKQ had good internal consistency (Cronbach’s alpha for all items = 0.898) and stability (Kappa coefficient >0.600). The average score for all equivalence criteria was 1.00, demonstrating good equivalence to the original. The significant difference between knowledge score and education level (p <0.001) confirmed construct validity.

Conclusion. Our study provided a reliable Vietnamese version of the DKQ. Future studies may apply the version in different regions in Vietnam to determine external validity.
