A cross-sectional study of existential concerns and fear of progression in people with Rheumatoid Arthritis

Abstract

ObjectivesPeople with rheumatoid arthritis (RA) have higher levels of fear of disease progression (FOP) than cancer survivors. In cancer, FOP is inextricably linked with existential concerns. However, this has not been investigated in people with RA. MethodsWe recruited 165 people with RA (96%F) who volunteered for a treatment trial of psychological intervention. Participants completed the Existential Concerns Questionnaire (ECQ) and questionnaires measuring constructs associated with FOP in cancer. We created groups of people with RA, with and without clinically significant levels of FOP (clinical and control groups) and compared their existential concerns. We hypothesized that existential concerns would add to the variance in FOP over and above pain, psychopathology, and disability. ResultsNearly two-thirds of people with RA scored in the clinical range for FOP. The clinical group had higher levels of all existential concerns than the control group. When subscales of the ECQ were entered into a multiple regression with FOP as the dependent variable, death anxiety, meaninglessness and guilt domains accounted for significant variance in FOP. Moreover, when added to a regression equation controlling all other variables, existential concerns continued to account for unique variance in FOP (t = 2.712, p = 0.007). ConclusionExistential concerns were strongly associated with FOP. While this cross-sectional study cannot determine whether existential concerns underlie FOP in RA, these results show robust relationships that warrant future investigation.
