  • The experience of Rheumatoid Arthritis (RA) includes significant suffering and life disruption. This cross-sectional study examined the associations between pain, catastrophizing, acceptance and physical limitation in 55 individuals (11 males and 44 female; Mean age = 54.37; SD = 18.346), from the Portuguese population with (RA) 2 years after the diagnosis; also explored the role of acceptance as a mediator process between pain, catastrophizing and physical limitation. Results showed positive correlation between pain and catastrophizing (r = .544; p = .001), and also between pain and 2-years� physical limitation (r = .531; p = .001) Results also showed that acceptance was negatively correlated with physical limitation 2 years after the diagnosis (r = �.476; p = .001). Path-analysis was performed to explore the direct effect of pain (ß = �.393; SD = .044; Z = 3.180; p = .001) and catastrophizing (n.sig.) on physical limitation and also to explore the buffer effect of acceptance in this relationship (indirect effect ß = �.080). Results showed that physical limitation is not necessarily a direct product of pain and catastrophizing but acceptance was also involved. Pain and catastrophizing are associated but the influence of catastrophizing on physical limitation is promoted by low levels of acceptance. Results emphasize the relevance of acceptance as the emotional regulation process by which pain and catastrophizing influence physical functioning and establish the basic mechanism by which pain and catastrophizing operate in a contextual-based perspective. Also the study results offer a novel approach that may help behavioral health and medical providers prevent and treat these conditions.
