The moderating effects of pain catastrophizing on the relationship between illness perceptions and self-reported signs of central sensitization in patients with persistent pain.

Abstract

Two factors related to the continuation of persistent pain are pain catastrophizing and illness perceptions. Pain neuroscience education is known to positively influence both in patients with persistent pain. As the integration of pain neuroscience education in monodisciplinary physiotherapy treatments is effective, integration in transdisciplinary cognitive-behavioral treatments seems recommendable. When doing so, the moderating effect of pain catastrophizing and perceptions on treatment results have to be examined, as these provide valuable information under which conditions treatment works. A bottom-up retrospective observational study evaluated the changes in clinical outcomes, and relationships between clinical outcomes and cognitive and emotional factors in patients with persistent pain. Multiple regression analysis, PROCESS macro, explored the moderating effects of pain catastrophizing on the relationship between illness perceptions and self-reported symptoms of central sensitization. In total, 78 patients were included in the study. A correlation between pretreatment scores and change scores in illness perceptions and self-reported symptoms of central sensitization following treatment were found (resp. R-sq 0.407, F(10,99) = 0.638, P = 0.000; R-sq 0.361, F(5, 54) = 0.609, P = 0.000; and R-sq 0.314, F(4,55) = 0.560, P = 0.00), however, moderation of pain catastrophizing scores on these correlations was not found. Even though an association between changes in pain catastrophizing and illness perceptions in patients with persistent pain was found, the direction or strength between the changes in illness perceptions and changes in self-reported symptoms of central sensitization was not influenced by pretreatment scores of pain catastrophizing.
