Bhaskaran 3 ; 1Ng Teng Feng General Hospital, 2 Temasek Polytechnic, 3School of Applied Science, Temasek Polytechnic Learning Outcome: To design a validated DRNK-Q for individuals with T2DM. Background: The study involved development of a validated questionnaire to assess diabetes related nutrition knowledge (DRNK) and its relationship with psychosocial self-efficacy in individuals with T2DM. Methods: First draft of DRNK-Q was tested for user friendliness and ambiguity (n¼21). Second draft was tested for item difficulty, index of discrimination and internal consistency (n¼62). Final draft was examined for construct validity and test-retest reliability (n¼100). DRNK-Q was administered with Diabetes Empowerment Scale-short form to measure DRNK and psychosocial self-efficacy in T2DM (n¼22). Results and Discussion: The final questionnaire was found to be consistent and reliable. The item difficulty and index of discrimination scores of the selected questions ranged from difficult to desirable (2 to 85) and from poor to very good (0.00 to 0.65). There is good internal consistency (Cronbach’s alpha: 0.838), construct validity (Independent t-test: p<0.001) and test-retest reliability (Intraclass correlation: 0.824-0.840). In this cross sectional analysis, subjects had fair DRNK and psychosocial self-efficacy scores [mean (SD): 13/ 27 (4.50) and 4/8 (0.73)]. There was no relationship between DRNK and psychosocial self-efficacy (adjusted generalized linear model: p¼0.119) within our sample. Conclusion: This is the first validated DRNK-Q for individuals with T2DM in Singapore and is a valid measure of DRNK that is consistent and reliable. Our study suggests that DRNK and psychosocial self-efficacy are independent. Hence, healthcare practitioners should assess them separately. Funding Disclosure: None
