Introduction. Although psychological factors and self-regulation processes rarely cause pain they have enough importance to exacerbate pain and contribute to its maintenance. Nevertheless, pain perception and associated beliefs can influence its confrontation and the sensation of intensity. Pain perception in fibromyalgia acquires special relevance due to an abnormal sensitivity to digital pressure on the so-called tender points. This constitutes the main factor for its differential diagnosis.
Method. The aim of the present study is to determine differences in pain perception and associated beliefs that appear between a group of patients with fibromyalgia (n = 36), a control group with chronic pain with objectified non-inflammatory locomotion apparatus pathology (n = 44) and a control group with healthy subjects (n = 31). Pain perception and beliefs concerning pain were assessed using Spanish versions of the following self-reports: West Haven Yale Multidimensional Questionnaire (WHYWP) and Pain Perceptions and Beliefs Inventory (PBAPI).
Results show that the difference between patients with chronic pain is not related to pain global perception, but rather to greater perception of pain as more incapacitating when carrying out every day activities in fibromyalgic patients. In this sense, these people use escape-avoidance strategies in their every day lives believing that pain incapacitates them and therefore that physical activity should be avoided.
Conclusions. Measurement of pain perceptions and beliefs could be considered relevant for assessment and for intervention programs on pathologies associated with chronic pain.
