BACKGROUND Illness perception has long been hypothesized to be linked to psychological well-b eing in patients with rheumatic diseases,although substantial evidence is lacking,and the contribution of ruminative coping style to this relationship is unclear.AIM To investigate the roles of illness perception and rumination in predicting fatigue and negative emotions in patients with chronic rheumatic diseases.METHODS Illness perception,rumination,fatigue and negative emotions(i.e.depression,anxiety and stress)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.RESULTS All five subscales of illness perception,including perceived illness identity,chronicity,cyclical nature,consequences and coherence of illness,were significantly associated with fatigue and negative emotions.In mediational analysis,rumination was found to mediate three components of illness perception(the identity,cyclical nature and consequences of illness)and negative emotions/fatigue.CONCLUSION 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.Our findings suggest that psychological intervention should target rumination to improve physical and emotional well-being of patients with chronic rheumatic diseases.
