BACKGROUND: Self-efficacy is associated with better type 2 diabetes (T2D) self-management. OBJECTIVE: To examine whether a 6-month virtual multi-component T2D self-management education (SME) program increases self-efficacy. METHODS: The current study is a secondary analysis of an ongoing quasi-experimental, treatment-only study. Participants were recruited between November 2022 and December 2023. Adults diagnosed with T2D, glycated hemoglobin (A1c) more than or equal to 8%, and no prior flash glucose monitor experience were included. The SME included biofeedback from glucose and physical activity monitors, group education, and elective exercise prescription. Self-efficacy was measured using the Stanford Diabetes Self-Efficacy Scale. Change in self-efficacy from baseline was assessed using a paired samples t-test (p<.05). RESULTS: Thirty-eight participants were enrolled (mean age [SD]: 54.6 [13.3] years, % female: 36.8). Mean self-efficacy score increased from 6.00 [SD 1.96] at baseline to 7.97 [SD 1.21] at six months (p<0.001). CONCLUSION: This SME program may have fostered self-efficacy, possibly leading to enhanced T2D self-management.
