ARTICLE HIGHLIGHTS
Research background

Although illness perception is proposed to be associated with psychological health in patients with rheumatic diseases, empirical evidence is lacking to support this hypothesis. Furthermore, the contribution of ruminative coping style to this relationship is unclear yet.

Research motivation

Psychological symptoms observed in patients with rheumatic diseases in clinical practice.

Research objectives

This study aimed to investigate the association of illness perception and fatigue and negative emotions in patients with chronic rheumatic diseases and the potential mediating effects of rumination.

Research methods

Illness perception, rumination, fatigue and negative emotions were assessed by the Illness Perception Questionnaire-Revised, Stress Reactive Rumination Scale, Multidimensional Assessment of Fatigue, and the Depression, Anxiety and Stress Scale respectively. Multivariate regression analysis, the Sobel test, and the bootstrap were used to identify the mediating effect of rumination.

Research results

All the subscales of illness perception were found significantly associated with fatigue and negative emotions. In mediational analysis, rumination mediated three components of illness perception (the identity, cyclical nature, and consequences of illness) and negative emotions/fatigue.

Research conclusions

Perceived identity, cyclical nature, and consequences of illness are significantly associated with fatigue and negative emotions in patients with chronic rheumatic diseases and these associations are mediated by rumination. Psychological intervention should target rumination to improve physical and emotional well-being of patients with chronic rheumatic diseases.

Research perspectives

Identification of the mediating role of rumination in the relationship between illness perception and negative emotions and fatigue has important implications clinically for developing cognitive interventions for patients with rheumatoid arthritis and systemic lupus erythematosus.
