Abstract
Patient education is a key element in the treatment of diabetes. Assessment of diabetes knowledge is important for optimum treatment, and for the assessment of this knowledge, a validated tool is essential. No such tool is available in the Indonesian language. The aim of this study was to translate and examine the psychometric properties of the Indonesian version of the 24-item Diabetes Knowledge Questionnaire (DKQ) among type 2 diabetes patients. The standard ‘forward–backward’ process was used to translate the DKQ into the Indonesian language. Later, it was validated with a convenience sample of 35 patients with type 2 diabetes, between July and September 2021. Internal consistency was assessed by reliability analysis; one-way analysis of variance was applied for known group validity; and multivariate linear logistic regression was applied for identifying significant predictors for patients’ DKQ score. Good internal consistency was observed for the DKQ (Cronbach’s α = 0.757). The results indicated that the Indonesian version of the DKQ-24 was a valid and reliable measuring instrument for measuring diabetes knowledge in the Indonesian sample.
