Purpose Little research has examined the role of pain catastrophizing (PC) in predicting suicide among patients with rheumatic disease or the mechanisms through which it works. This study examines whether depression, perceived social support (PSS), and perceived burdensomeness (PB) mediate the relationship between PC and suicide risk. It also examines the relative importance of sociodemographic, clinical, and psychological factors in predicting suicide risk. Methods Three hundred sixty patients from a rheumatology clinic in Korea completed measures of pain catastrophizing, social support, depression, and perceived burdensomeness. Results In hierarchical multiple regression analysis, the PC magnification, PB, physical disability, and PSS were significantly related to suicide risk. Results of the serial multiple mediation analysis indicated that the total indirect effect of PC magnification on suicide risk was significant while the direct effect was not. Four specific indirect effects of PC magnification were found to be statistically significant. First of all, PC magnification was associated with suicide risk through PB and through depression and PB. PC magnification was also associated with suicide risk through depression and PSS. Lastly, PC magnification was associated with suicide risk through depression, PSS, and PB. Conclusions The identified pathways through which PC affects suicide risk suggest the importance of depression, PSS, and PB. Evaluation and intervention targeted at physical disability and the psychological factors of PC magnification, depression, PSS, and PB may be integrated into the management of suicide risk in patients with rheumatic disease.
