Family Function and Self-Management of Patients With Early Chronic Kidney Disease: The Mediating Roles of Self-Perceived Burden and Ego Depletion.

BACKGROUND

Effective self-management in the early stage of chronic kidney disease (CKD) is key to delaying disease progression. However, no studies have confirmed that the combined support of internal individual factors and external family environmental factors may play an important role in the self-management of patients with early CKD.

PURPOSE

This current study aims to explore the effect of family function on the self-management of patients with early CKD and examine the mediating roles of self-perceived burden and ego depletion.

PATIENTS AND METHODS

Three hundred and sixty patients with stage 1-3 CKD participated in the cross-sectional survey and completed structured questionnaires, including the family APGAR index, self-perceived burden scale, self-regulatory fatigue scale and chronic kidney disease self-management instrument. Mplus 8.3 was used to establish a structural equation model.

RESULTS

Family function had a positive predictive effect on self-management ( = 0.231, < 0.001). Self-perceived burden and ego depletion were not only single mediating variables between family function and self-management but also played a chain-mediating role. The total indirect effect was 0.304 (95% CI: 0.234 to 0.388, < 0.001), accounting for 56.82% of the total effect ( = 0.535, 95% CI: 0.420 to 0.651, < 0.001).

CONCLUSION

This study highlights the importance of self-management for patients and their families and provides new important theoretical guidance for multiple interventions of improving family function, reducing self-perceived burden and ego depletion to improve self-management, which is of great value in delaying the progression of renal disease.
