Diabetes conflict outstrips the positive impact of self-efficacy on youth adherence and glycemic control in type 1 diabetes

Objective: To examine whether self-efficacy buffers the deleterious consequences of diabetes-specific family conflict on self-monitoring blood glucose (SMBG) and glycated hemoglobin (HbA1c) in youth with type 1 diabetes mellitus (T1DM). Methods: A total of 129 youth with T1DM (aged 10-16 years) completed measures of diabetes-specific family conflict and self-efficacy for diabetes management, and their blood glucose meter data and HbA1c were extracted from the electronic medical record. We preformed moderation analyses to examine whether self-efficacy moderated the association that diabetes-specific family conflict had with SMBG and HbA1c. We used simple slopes analyses to probe significant interactions. Results: Our results indicated that self-efficacy moderated the association that diabetes-specific family conflict had with SMBG and HbA1c. The pattern of these findings showed that high self-efficacy buffered the negative impact of diabetes conflict on HbA1c. However, benefits of high self-efficacy for more frequent SMBG was only apparent in the context of low diabetes-specific family conflict. Conclusions: Study findings highlight the interactive relationship between diabetes-specific family conflict and self-efficacy in relation to SMBG and glycemic control. These findings suggest that family functioning and youth's self-efficacy are promising intervention targets for families having trouble with SMBG and HbA1c.
