Predicting Factors for Rapid Progressive Chronic Kidney Disease in Primary Glomerular Disease Patients with Moderate-to-Severe Stage

The Mediating Role of Psychological Well-Being in the Relationship between Self-Care Knowledge and Disease Self-Management in Patients with Hypertensive Nephropathy

Objective: This study aimed to investigate the correlation between self-care knowledge, psychological well-being, and disease self-management in patients with hypertensive nephropathy, and to assess the effect of psychological well-being as a mediator of self-care knowledge and disease self-management. Methods: This is a cross-sectional study. The 220 patients with hypertensive nephropathy were recruited from a teaching hospital in Taiwan using purposive sampling. The average age was 70.14 (SD = 11.96) years old. Among them, 128 (58.2%) were male and 92 (41.8%) were female. Instruments included a hypertensive nephropathy self-care knowledge scale, the World Health Organization-5 Well-Being Index, and the chronic kidney disease self-management instrument. The mediating effect was determined with linear regression models and the Sobel test. Results: The total explanatory variation of age, systolic blood pressure, psychological well-being, and self-care knowledge on the disease self-management was 27.7%. Psychological well-being was the most important explanatory factor and alone explains 16%. Psychological well-being was a partial mediator of self-care knowledge and quality of life in patients with hypertensive nephropathy, with a total effect of 23.2%. Conclusions: This study showed that older patients with hypertensive nephropathy and those with a higher systolic blood pressure had lower levels of disease self-management. The higher the patients’ self-care knowledge and psychological well-being, the better their disease self-management.

Disease Knowledge, Self-Efficacy, and Quality of Life in Patient With Hypertensive Nephropathy

The purpose of this study is to investigate the relationships among disease knowledge, self-efficacy, and quality of life in patients with hypertensive nephropathy. A cross-sectional and correlational design is employed in this study, and a total of 213 participants are collected by convenience sampling from the outpatient Department of Nephrology of a regional teaching hospital in Taiwan. The research instruments include the Hypertensive Nephropathy Knowledge Instrument, the Chronic Kidney Disease Self-Efficacy Instrument, and the Medical Outcome Study Short Form-12, and stepwise multiple regression analysis is used to test the explanatory power of each significantly-correlated independent variable regarding the quality of life. The results show that the higher the disease knowledge, the better the self-efficacy, and the better the quality of life, and self-efficacy is the most important predictor of the quality of life.
