Intolerance of uncertainty moderates the relationship between catastrophizing, anxiety, and perceived pain in people with chronic nononcological pain.
Abstract
Substantial empirical evidence has shown that intolerance of uncertainty is a central transdiagnostic feature in psychopathology and it has been suggested to be a pain-related psychological factor contributing to the experience of chronic pain. However, research in this area is virtually nonexistent. The objective of this study was to investigate associations between pain severity, catastrophizing, and anxiety in people with chronic nononcological pain, while assuming that intolerance of uncertainty moderates these relationships.
