Successful daily self-management of diabetes is essential to the achievement of positive health outcomes. Basic to successful self-management of any disease is a sense of self-efficacy, or the feeling of confidence in one's self-management abilities. This study examined the association of these variables on the achievement of glycemic control, specifically A1C levels. This study used a retrospective cohort design to evaluate the predictive relationship of self-efficacy and self-care behaviors on A1C level. After Institutional Review Board approval was obtained, 60 medical records were accessed of people ≥ 18 years of age with type 1 or type 2 diabetes who were seen consecutively in a primary care practice located in an urban setting. Data analysis revealed no statistically significant relationships between global measures of self-efficacy and self-care and A1C levels. However, there were two questions from the Stanford Diabetes Self-Efficacy for Diabetes Scale found to be significantly related to A1C (P 0.009). Those whose diabetes was well controlled were confident in selecting appropriate foods when hungry and in their ability to exercise for 15–30 minutes, four to five times per week. These findings, if replicated in future studies, may provide clinicians an opportunity to develop and test targeted self-management interventions yielding the highest probability of improved glycemic control.
Beckerle et al. (2013) studied this question.
