The current randomized controlled study evaluated the effects of a health literacy-considered diabetes self-management program on diabetes-related parameters: diabetes self-management knowledge (DSK), diabetes health beliefs (DHB), diabetes self-efficacy (DSE), diabetes self-management behavior (DSMB), and diabetes biomarkers. Fifty-one Korean older adults with diabetes completed 12 weekly sessions that were developed based on their health literacy and health-related characteristics. The results indicate significant posttest differences between groups in DSK (p = 0.046), DSE (p = 0.046), DSMB (p = 0.012), and the DSMB self-monitored blood glucose subscale (p = 0.002). Significant pre-post changes between groups were observed in the DHB benefit subscale (p = 0.043), DSE (p = 0.006), DSMB (p = 0.008), DSMB diet (p = 0.029), and the self-monitored blood glucose subscale (p < 0.001). A significant pre-post difference was observed in the intervention group's HbA1c levels (p = 0.008). The program effectively improved participants' DSK, DHB, DSE, and DSMB values, which may be helpful for improving HbA1c levels. [Res Gerontol Nurs. 2017; 10(5):215-225.].
