Older adults experience the greatest burden of diabetes. Resources must be available and accessible to empower older adults to perform diabetes self-care. The purpose of this study was to evaluate a videophone motivational interviewing (MI) diabetes self-management education (DSME) intervention to improve glycemic control of rural older adults. Sixty-six participants (mean age = 64.9 years, range 60-81) with uncontrolled diabetes were enrolled in a 6-month videophone intervention. Experimental group participants (n = 34) received weekly, then monthly, videophone MI DSME calls, whereas control participants (n = 32) received monthly videophone healthy-lifestyle education calls. Although both groups experienced a decreased HbA1c, there was a statistically significant difference in experimental group mean values (p = .015), but not the control group (p = .086). The experimental group demonstrated statistically significant increases in diabetes knowledge (p = .023) and diabetes self-efficacy (p = .002). Experimental group participants with high self-efficacy in contrast to low self-efficacy had a statistically significant decrease in HbA1c (p = .043).
