Objective
We assessed the relationships between supportive and obstructive family behaviors and patients’ diabetes self-care activities and HbA1C, and potential interaction effects and differences by demographic characteristics.
Methods
In a cross-sectional study, 192 adults with type 2 diabetes completed the Diabetes Family Behavior Checklist-II, the Summary of Diabetes Self-Care Activities, and a glycemic control (HbA1C) test.
Results
Participants reported similar rates of supportive and obstructive behaviors that were positively correlated (rho=0.61, p<.001). In adjusted analyses, supportive family behaviors were associated with adherence to different self-care behaviors (β=0.20–0.50, p<.05), whereas obstructive family behaviors were associated with less adherence to self-care behaviors (β=−0.28–−0.39, p<.01) and worse HbA1C (β=0.18, p<.05). Supportive behaviors protected against the detrimental effect of obstructive behaviors on HbA1C (interaction β=−0.22, p<.001). Non-Whites reported more supportive and obstructive behaviors than Whites, but race did not affect the relationships between family behaviors and self-care or HbA1C.
Conclusion
Involving family members in patients’ diabetes management may compromise patients’ self-care and glycemic control unless family members are taught to avoid obstructive behaviors.
Practice Implications
Our findings endorse interventions that help family members develop actionable plans to support patients’ self-care and train them to communicate productively about diabetes management.
