Effects of Illness Perception and Coping Style on Self-Management in Peritoneal Dialysis Patients: A Cross-Sectional Study.

Aim: Chronic disease self-management is critical to disease prognosis and patient quality of life. Several psychological factors influence this process of self-management. In this background, the present study investigated the impact of illness perceptions and coping style on self-management in people with peritoneal dialysis (PD). Methods: The study is a cross-sectional study. From May 2022 to January 2023, a convenience sampling method was used to recruit 246 peritoneal dialysis patients. General information questionnaire, brief illness perception questionnaire, medical coping style modes questionnaire and the self-management scale for peritoneal dialysis patients were used in this study. We used SPSS 24.0 to analyze the data, and the statistical methods included descriptive analysis, single factor analysis, Pearson correlation analysis and multiple linear regression analysis. Results: A total of 246 patients were included in this study (93.89% response rate). Cognitive representations and emotional representations were 30.40, 14.18, respectively. However, illness comprehensibility was 2.87. Illness perceptions were negative significantly correlated with self-management. With regard to coping style, our patients were more likely to adopt avoidance and resignation coping style. Confrontation and avoidance were positively related to self-management, while acceptance-resignation was negatively related. Conclusion: Self-management of peritoneal dialysis patients needs to be improved. Age, female sex, monthly income, illness perceptions and coping style were independently associated with self-management. Impact: These findings suggest that interventions that improve illness perceptions and coping style should be explored to ultimately improve their self-management. For example, patients can be provided with psychological counseling so that they can face the disease correctly, and we should pay attention to the positive role of social support.
